The two American astronauts Robert Behnken, 49, and Douglas Hurley, 53, who have both flown twice, took off on Saturday May 30, 2020 aboard the Crew Dragon capsule, launched by a Falcon-9 rocket from SpaceX from Florida.

It is the first time that a manned mission has been operated by a private company. The spacecraft was designed by billionaire Elon Musk's company.

Initially scheduled for Wednesday at 4.33 p.m. (10.33 p.m. Paris time), the launch could not take place.

The countdown was interrupted seventeen minutes before takeoff due to poor weather conditions in the Kennedy Space Center.

Taking advantage of a clearing, the rocket of the company founded by Elon Musk took off on Saturday at 3:22 p.m. (9:22 p.m. Paris time) and placed the Crew Dragon capsule in orbit unhindered ten minutes later.

A successful takeoff

Once the astronauts were on board, the rocket was full of fuel and the Falcon-9 was able to leave Florida soil.

After two and a half minutes, the first floor stopped pushing and came off; the second stage engine started soon after.

The body of the first stage began its controlled descent with retro-fuses to land on the barge in the Atlantic nine minutes and twenty-two seconds after takeoff.

Less than three minutes later, the second stage of the rocket in turn detached from the capsule.

As for the flight plan, astronauts Hurley and Behnken must automatically dock at the International Space Station (ISS) approximately nineteen hours after takeoff from the old lunar mission launch pad.

They will support the three members of the Russian-American crew there in their scientific experiments - the primary mission of the ISS -, before leaving for Earth in their Crew Dragon capsule, which will land in the Atlantic Ocean before the end of summer. And if all the lights are green, after this test mission, another mission, the first known as “routine”, will be launched before the end of the year towards the station.

The Crew Dragon capsule should then be in orbit and dock with the International Space Station (ISS) on Sunday.

Reducing the American coat of arms

With this inaugural flight, the Americans intend to restore their coat of arms and regain their independence by ending the monopoly of the Russians for the transportation of astronauts to the International Space Station (ISS), after ten years of hitchhiking on board Soyuz vessels . The last space mission "100% Made in USA" dates back almost a decade

Savings for NASA

For NASA, the Crew Dragon capsule is also a good way to save money. Because to continue sending astronauts into orbit, the United States has relied so far on the Russian Soyuz spacecraft, launched from the historic Baikonur Cosmodrome in present-day Kazakhstan.

A costly collaboration: the price of a Soyuz seat cost the American taxpayer $ 86 million this year. By comparison, a seat on the Crew Dragon is estimated at $ 55 million. A considerable gain, when the American space shuttle, it returned to 450 million dollars per mission.

The manned flight of the SpaceX capsule to the International Station opens a new era in space exploration.

SpaceX also intends to make private passengers travel in orbit, or even in the ISS, perhaps next year.

The Pentagon has officially released three videos taken by U.S. Navy pilots showing in-flight encounters with what appear to be unidentified flying objects, which were previously leaked on the internet and published by To The Stars Academy of Arts & Sciences, a private company, in 2017 and 2018.

"After an in-depth examination, the Defense Department determined that the publication of these videos did not reveal sensitive information", explains the Pentagon, which wants to "clarify any public misconception about the reality or not of these images" by making them public.

The videos, which the Navy confirmed to be true last September, "do not intrude on any further investigation into incursions into military airspace by unidentified aerial phenomena," spokeswoman Sue Gough said in this release. of the Pentagon, to justify their declassification.

The videos, which are all in black and white, bear the names of "FLI R", "GOFAST" and "GIMBAL", and are now available on the Naval Air Systems Command website

One of these videos dates from November 2004, the other two from January 2015. Captured by F18 Hornet on-board fighters, these videos first show an object shooting at a very high speed above the waves.

"The observed aerial phenomenon remains qualified as" unidentified ", assures the Pentagon.

On another video, above the clouds, this time appears a much larger UFO.

The pilots of the two US Navy planes that have it in their sights are wondering if it is a drone.

"Look at that: there is a whole swarm of it

[...] The cow, they are all going against the wind !"

A west wind of 120 knots ! " Look at this thing !" ", Continues his interlocutor when the object begins to rotate." Like a ping pong ball "

Now retired navy pilot David Fravor, who encountered one of these "UFOs" in 2004, told American television station CNN in 2017 that the object was moving erratically. "As I approached him [...] he quickly accelerated south and disappeared in less than two seconds."

It was "like a ping pong ball bouncing off a wall," he said. In a statement, the United States Department of Defense explained that it had decided to broadcast these images "in such a way as to dissipate all public misconception about the veracity or not of the videos already taken up in the media ”. After this official development, everyone is now free to imagine everything.

Harry Reid, a former Nevada senator, home of the US Air Force's ultra-secret Zone 51 facilities, welcomed the declassification, while deploring that "it only scratches the surface of research and documentation available ”.

"The United States must take a serious and scientific look at this and all the potential national security implications. The American people deserve to be informed, " he continued. In December 2017, the Defense Department admitted that it had financed until 2012, the official date of its completion, a secret program costing several million dollars intended to investigate UFO sightings.

These videos are much more original than other military documents since they are supposed to reveal the object of all our fantasies, or rather objects ... unidentified flying objects.

This night look up to the sky to contemplate the immense wealth of the Universe that we offer 21 to 22 April a beautiful meteor shower, the Lyrids.

Comet dust

Like every year in April, our planet crosses the path of comet C / 1861 G1 Thatcher in its stellar journey. From this meeting, shooting stars are born which will streak our sky with a very particular intensity.

This year, the culmination of this phenomenon called the Lyrids will take place on the night of Tuesday, April 21. It will thus be possible to observe up to 20 shooting stars per hour.

Originally, the Lyrids are dust left by this comet in its wake.

These small meteors then “ignite” when they enter our atmosphere at more than 49 km / s according to NASA.

Peak activity around 6:40 am

The rain of shooting stars from the Lyrides can be watched all night from 0:40 am Paris time.

However, the International Meteor Organization (IMO) specifies that the peak of activity could actually take place around 6:40 am on April 22. Better to get up early to enjoy it!

In addition, unlike the rain of 2019, we will not be bothered by the brightness of the Moon which is close to its new phase and therefore invisible for the moment.

For ten years, no tourist has been able to approach the International Space Station (ISS). This was without counting on SpaceX, the aeronautical company of the whimsical Elon Musk, launched at full speed in the conquest of space.

After announcing in February a partnership to send four private customers into orbit by 2022, SpaceX is now attacking the International Space Station (ISS). Musk's company announced Thursday that it has signed an agreement with Axiom Space to give it seats on board its Crew Dragon capsule.

The launch of the operation is planned for the second half of 2021. This trip "will mark a turning point in the universalization of access to space", welcomed the boss of Axiom Space, Michael Suffredini. On this occasion, three people should be able to spend 10 days on board the ISS for $ 55 million.

But SpaceX is not the only company that wants to touch the stars. Virgin Galactic (Richard Branson) and Blue Origin (Jeff Bezos) are also involved in space tourism.

They are currently developing vessels capable of sending private passengers, for a few minutes, just over the border of space (80 or 100 km depending on the definitions chosen by each company), for 250,000 dollars or more in the case of Virgin.

Boeing is also developing a vehicle for NASA, Starliner, to join the ISS. The company wants to make private passengers travel there in the future

Those traveling to the ISS will be supported on the SpaceX Falcon 9 reusable rocket. Musk's company has already signed another partnership with a company called Space Advnetures with the aim of offering a five-day trip, for four passengers, aboard the Crew Dragon capsule.

Eight space tourists have already made a trip to the international station in the Russian Soyuz rockets. Latest: Cirque du Soleil founder Guy Laliberté in 2009.

L’agence spatiale américaine a annoncé, lundi 6 janvier 2020, que son télescope avait permis de découvrir une nouvelle planète de la taille de la Terre et à une distance ni trop proche, ni trop éloignée de son étoile pour que de l’eau liquide y soit – peut-être – présente.

Baptisée « TOI 700 d », cette planète se trouve à cent années-lumière de la Terre. Elle a été découverte par le satellite TESS, grâce à l’œil vigilant de plusieurs astronomes amateurs.

Le satellite TESS (Transiting Exoplanet Survey Satellite) commence à atteindre ses objectifs, soit « trouver des planètes de la taille de la Terre et en orbite autour d’étoiles proches », a déclaré Paul Hertz, directeur de la division d’astrophysique de la NASA.

Une étoile pour trois planètes

Baptisée « TOI 700 d », cette planète est relativement proche de nous : à cent années-lumière. Quelques autres planètes de type similaire ont été découvertes auparavant, notamment par l’ancien télescope spatial Kepler, mais c’est la première par TESS, lancé en 2018. Ce satellite fixe une partie du ciel pour détecter si des objets – des planètes – passent devant des étoiles, ce qui cause une baisse temporaire de luminosité de l’étoile. Cela permet à TESS d’inférer la présence d’une planète, sa taille et son orbite.

L’étoile TOI 700 est petite, environ 40 % de la taille et de la masse de notre Soleil, avec une température de surface inférieure de moitié. TESS a découvert trois planètes autour de cette étoile, nommées TOI 700 b, c et d. Seule la « d » est dans la zone dite « habitable ». Elle fait presque la taille de la Terre (20 % de plus) et fait le tour de son étoile en 37 jours. Elle reçoit 86 % de l’énergie fournie par le Soleil à la Terre.

Mais reste à savoir de quoi elle est composée. Les chercheurs ont utilisé des modèles climatiques prédictifs. Sur les 20 versions générées, une au moins est proche de la Terre, sans les océans, avec des vents soufflant de la face cachée vers la face éclairée, quand une autre ressemble plutôt à la planète Mars quand elle était jeune.

De multiples astronomes vont désormais observer la planète avec d’autres instruments, obtenant de nouvelles données qui correspondront peut-être à l’un des modèles prédits par la NASA.

L’astronaute Anne McClain est accusée d’usurpation d’identité et d’accès irrégulier aux dossiers financiers de son ex-épouse alors qu'elle séjournait dans la Station spatiale internationale (ISS).

Ce pourrait bien être le premier délit commis dans l’espace.

C'est le New York Times qui a révélé samedi ce scoop:

La Nasa enquête actuellement sur les agissements de l’astronaute Anne McClain, accusée d’usurpation d’identité et d’accès irrégulier aux dossiers financiers de son ex-épouse depuis la Station spatiale internationale (ISS). L’Américaine a séjourné dans l’espace pendant six mois, entre décembre 2018 et juin 2019.

Le quotidien américain raconte ainsi que l’ex-femme de McClain, Summer Worden, une agente de renseignement de l’Air Force américaine, s’interrogeait l’année passée sur les informations dont semblait avoir connaissance son ancienne conjointe.

Après avoir sollicité sa banque pour connaître la localisation des dernières connexions à son compte, Worden s’est vue informer que certaines d’entre elles provenaient d’ordinateurs de la Nasa. Or McClain, qui devait faire partie de la toute première sortie 100% féminine dans l’espace, a reconnu avoir accédé à ce compte bancaire à bord de l’ISS.

Son avocat a affirmé que sa cliente n’avait rien fait de mal, cherchant simplement à surveiller le compte joint du couple, ce qu’elle faisait au cours de leur relation, pour s’assurer que son ex-femme avait assez d’argent pour élever leur enfant. Anne McClain indique avoir continué à utiliser le même mot de passe qu’auparavant, lorsqu’elles étaient encore en couple, sans savoir qu’elle n’en avait plus le droit.

Selon le New York Times, Summer Worden a donc déposé plainte auprès de la Commission fédérale du commerce (FTC), une agence indépendante, ainsi qu’auprès de l’inspection générale de la Nasa.

Sur Twitter, Anne McClain a déclaré qu’il n’y avait «absolument rien de vrai dans ces informations». «Nous avons vécu une séparation douloureuse et personnelle qui se retrouve hélas désormais dans les médias. J’apprécie le soutien que l’on m’a apporté et je réserve mes commentaires pour la fin de l’enquête. J’ai une confiance totale dans le processus de l'inspection générale.

Il pourrait donc bien s’agir du premier délit spatial.

Ce n'est pas la première fois que des actions en justice ont été intentées mais elle n’avaient jamais impliqué une personne en mission.

Ainsi en 2011, selon le New York Times, la Nasa avait organisé une opération d’infiltration avec pour cible la veuve d’un ingénieur spatial voulant vendre une roche lunaire.

En 2017, un homme d’affaires autrichien a poursuivi en justice une entreprise de tourisme spatial : il voulait récupérer une caution déposée pour un voyage dans l’espace qui ne semblait pas près de se produire.

Des délits commis dans l’espace appelés à se reproduire avec le développement du tourisme spatial.

A robot departing for the ISS

Russia launched on Thursday, August 22, a rocket for the International Space Station (ISS) with on board a humanoid robot named Fedor .

According to Navias, a NASA representative, Fedor "looked good, sitting in the shuttle commander's seat."

Fedor carrying the Skybot F850 identification number took off at 6:38 am (Moscow time) aboard a Soyuz rocket from the Russian Baikonur Cosmodrome in Kazakhstan to join the ISS.

After his arrival scheduled for Saturday, August 24, the anthropomorphic robot, which measures 1.80 m and weighs 160 kg, will begin a stay of ten days.

Fedor shares its travel capsule with 660 kilograms of goods, including food supplies, and supplies for the ISS crew.

Purpose of this mission

Once arrived at destination, no rest for the robot: it is expected by the Russian cosmonaut Alexander Skvortsov who will be responsible for supervising during his stay on the ISS. Fedor will have to carry out different tasks. Able to imitate human movements, it has been designed to assist astronauts in their daily lives.

"His operations will lead him to use a screwdriver or keys," said Alexander Blochenko, director of promising programs at the Russian Space Agency (Roskosmos), in an interview with Rossiyskaya Gazeta newspaper.

The robot will also have to test its capabilities in very low gravity conditions.

A Fedor to perform all these tests successfully to conquer the deep space.

Communication operation

It is also a big communication operation for Russia that did not fail to retransmit the take-off on television and during which the robot pronounced

"Let's go, let's go! ".

Words that obviously refer to those uttered by Yuri Gagarin in 1961, when he made the first flight of a man in space.

Like any good modern self-respecting humanoid, Fedor has its own Instagram and Twitter social network accounts on which he shares his daily life:

"I am going to fulfill the mission entrusted to me. What is the space still hiding? "Released the robot before leaving.

In the meantime, Fedor has certainly not finished making the buzz.

He will be back on Earth on September 6th, still aboard Soyuz.

Franky Zapata, "the flying man", made the crossing of the Channel Sunday morning, August 4, standing on his flying board.

The Frenchman has traveled 35 kilometers of strait on his "Flyboard" with five mini-turbojet allowing him to fly up to 190 kilometers per hour, with a range of about ten minutes.

The jet ski champion took off at 8:15 am near the beach of Sangatte (Pas-de-Calais) to reach St Margaret's Bay English side in the space of about twenty minutes.

He flew over the sea about 15 meters high and made a halt halfway on a boat, to refuel in kerosene.

During the 14th of July military parade on the Champs-Elysées Franky Zapata had already given a demonstration, in front of Emmanuel Macron:

he had stolen a rifle in his hands, several tens of meters above the ground, on his flyboard.

The French army invested in this device 1.3 million euros of subsidy.

"It can be used to evacuate a casualty, what is called a medical evacuation, it can serve as a logistics platform to carry ammunition," says the director of the Defense Innovation Agency, Emmanuel Chiva.

The French special forces see in this flying platform the "potential for employment in special operations in urban areas".

In the United Kingdom, a former reservist, Richard Browning, also invented his own flying machine equipped with five integrated reactors. A battle of the airs which is only beginning.

In the framework of the "Active Defense of Satellites, Unified Command", new investments have been presented by the Minister of Armies, Florence Parly, for a new defense space strategy that places the army at the center of the extra-ordinary game. atmospheric.

As a historical reminder in 1967, the entire international community agreed that all humankind would benefit from the conquest of space.

A great treaty signed that year that is still in force!

The latter spoke emphatically of "the use for the good of all peoples and for peaceful purposes of space".

But a radical change half a century later, space now seems to the eyes of politicians and military the fourth medium, in the military sense, after the land, sea and air.

In an objective of guiding or detecting missiles, to communicate, to make intelligence and espionage of others, armies depend largely on outer space,

Like Americans and Russians, France now intends to invest space militarily.

Current Minister of the Armed Forces, Florence Parly, presented in Lyon the new "defense space strategy", wanted by Emmanuel Macron, who had already put forward the idea about a year ago.

France will not launch into the destruction of satellites, as did China, the United States or more recently India, but will launch into a surveillance and very military objectives however.

France will not put into orbit weapons of mass destruction, blinding lasers or offensive nanosatellites, prohibited by the Treaty of 1967 and ratified by the French State,

France, however, intends to continue militarization and embark on the weaponization of space.

First objective the protection of the French satellites, ensures the ministry of the Armies.

Indeed Florence Parly had revealed that "in January the Russian spy satellite Louch-Olympe had discreetly approached the Athena-Fidus, used for telecommunications, including military, France and Italy.

In a framework of "active defense", Emmanuel Macron, wants by surveillance cameras soon embarked on Syracuse (central device for the communications of the French army) to protect and monitor the space, in order to detect approaches.

From 2023, France plans to no longer respect the 1967 treaty using blinding lasers, machine guns to break the solar panels feeding intruders, "clouds of nanosatellites watchers" deployed around the most strategic devices.

Hello the pollution of the space which is already well encumbered by so much waste in low and medium orbit and here is a beautiful example of ecology which Emmanuel Macron knows so well to speak !!

Florence Parly acknowledged that "France had fallen behind in terms of power lasers", but that it would "make up for France's gap by 2025, which will cost 700 million euros"

This expense is in addition to the 3.6 billion euros already planned for space in the military programming law for a global envelope of armies.

In comparison with the investments of the great powers: each year, the United States devotes 50 billion dollars, China 10 billion and Russia 4 billion.

Florence Parly wants more autonomy, and therefore become a "space operator", within the meaning of the 2008 law that regulates so far the extra-atmospheric activities.

The government does not exclude a legislative amendment.

The role of the National Center for Space Studies (CNES), a civil administration, will be reduced when it comes to military activities.

A large space command also needs to be created on September 1, with 220 people at the beginning, to streamline governance, and eventually the air force will become "the air force and the air force." space".

The Minister of the Armies Florence Parly wants to regulate the space activity beyond its strict perimeter, even going to give an assent for any outside activity, even private!

Florence Parly finally wants to benefit from the progress of commercial satellite imagery by buying terrestrial observation services, in addition to the means available to them (the CSO satellites of the Musis program), but also to "limit the use, so that these high-definition images that are very cheap, sometimes even free, do not end up in all hands! "

Florence Parly wants to "forbid the States purchasing French equipment to photograph certain areas, particularly the deployments of the French forces in operation"!

France forgets that space does not belong to it and NASA, companies such as "SpaceX", " Virgin Galactic", "Blue Origin", "Boeing" and many others do not care about the opinion of France , that's another reason for Donald Trump to get angry, France should be aware of it!

Evidence that is no longer in doubt, after the Gafa Tax, and now the space. If France and its leaders do not radically change their behavior, the retaliatory measures will take another dimension, yet from 1668 the famous French author Jean de la Fontaine wrote the fable "The Frog who wants to be as big as the ox" the latter should nevertheless inspire France

Space does not belong to France, it is not the master of the place either, it does not have any force or legitimate laws on the space, it does not have more right on the space than the other states of the planet, it is necessary to think that if other forms of life in the universe exist, they make fun of the rules that France would like to impose on them, the organs of other states like NASA, JAXA ..., as well that private companies like SpaceX, Virgin Galactic, Blue Origin, Boeing do not have to submit to France !!!

Donald Trump is patient but patience has its limits. Let's hope that he does not manage to say like "Rambo": "it's going to be silly" because we know that it will hurt a lot for those who want to attack America !!!!

Simon Freeman Washington for DayNewsWorld



The opportunity was given to Donald Trump to express his space ambition for America. On the fiftieth anniversary this weekend, the first American steps on the moon, the President of the United States received at the White House former astronauts Buzz Aldrin and Michael Collins of the Apollo 11 mission (Neil Armstrong died in 2012). "We do not know what we will find on Mars, but it will certainly be a very interesting trip," Donald Trump then said.

"The Moon is our test bed for our future mission to Mars. That's why we're going to the moon, "said NASA boss Jim Bridenstine.

Indeed, the expeditions mounted by NASA on the Moon serve both to advance technological and scientific advances that prepare an expedition to Mars.

Scientific progress ... still today

The chip and embedded system are an example. The rocket thus participates as much as it benefits from a development of computer science, which will have to answer ever more technical software, but also a huge dose of sensors to record everything and study during the test phases. The Apollo computer is the world's first integrated circuit (an electronic chip) and the first to have an embedded system.

Beyond the direct effects, the lunar conquest has had indirect benefits for the world of businesses and sciences: project management, crisis, planning, interdisciplinary cohabitation ... Methods still used fifty years later.

But scientific progress does not stop at this step on the Moon. A myriad of lunar rocks were reported or 382 kilos in all for all the Apollo missions that helped understand the Earth-Moon system.

"Today, the most popular theory is that our satellite was formed by an impact with a planet the size of Mars that would have hit the prototerre. This idea began with the return of the lunar samples, when we saw that the materials extracted there looked surprisingly like terrestrial materials. "Develops Athena Coustenis.

Rich in technological teachings as scientists, the Moon also serves as a springboard for walking on Mars.

The moon a stepping stone for Mars

Although no program has been officially approved, NASA's boss recalls that the agency "is working on developing a detailed plan on how to conduct a mission to Mars using the technologies that [she is going to ] to prove on the Moon ". Regarding the report of the Science and Technology Policy Institute, Bridenstine wants to believe that there are "assumptions in this relationship that everyone may not agree with" and that there are "alternatives that allow a mission to Mars in 2033, "he said.

With its program Artemis, NASA discount the return of astronauts on the Moon in 2024. An ambitious goal within five years and a lunar experience that should also serve to target Mars. For the administrator of the US space agency, it is thus necessary to use the Moon as a "test bed" in the perspective of Mars.

A first mission inhabited towards the red planet could be carried out in 2033.

A direct mission to Mars can not take place as many problems are still unresolved. The NASA boss also pointed out that a Gateway space station in lunar orbit allowed access to more parts of the solar system.

Jim Bridenstine is optimistic, setting a new goal for 2033 to send a mission to the Red Planet.

Although some experts doubt that NASA will be able to guarantee a landing of astronauts on the Moon in five years as President Trump wants, the Artemis mission aiming for a return to the Moon in 2024 is on track. And 2033 is the goal of NASA to send men to Mars.

"The destiny of humanity is to walk on another planet and we can do it ..." said Buzz Aldrin, pleading for manned missions to Mars.

"The colonization of the solar system is a way to establish another place of survival for the human race", which will become necessary one day according to him.

Fifty years after the first step of a human on the Moon, the conquest of the Moon is experiencing renewed interest. The NASA aims to send a man back and send the first woman to the moon by 2024. This is the Artemis program. But before we can pronounce the words "It's a big step for the woman ...", NASA has planned a whole range of projects to the number of 12.

With its program Artemis, NASA hopes to reconquer the Moon. Three major phases are planned: an unmanned flight in 2020; astronauts on lunar soil in 2024; then a permanent and autonomous base around 2028.

For the second phase of 2024, the US space agency announced no less than 12 research projects. Their common goal: to advance our understanding of the moon while testing scientific hypotheses and technological innovations. The results will best prepare the arrival of astronauts and their installation.

NASA also states that these projects will be able to find even wider applications for Mars exploration and beyond. The equipment will be transported using Commercial Lunar Payload Services, a series of contracts with private companies to which NASA will subcontract the lunar cargo ships.

Scientists will test hypotheses and test new equipment. Side assumptions, we find for example the LuSEE experiment (for "Lunar Surface Electromagnetics Experiment").

It must measure the electromagnetic phenomena on the surface of the Moon. Let us also mention the RAC Payload, a study seeking to study the adhesion of the regolith (the material found on the surface of the Moon) to other materials of the star.

Hardware and technological experimentation, they are more numerous.

The LISTER probe will measure the heat levels inside the Moon. This instrument can drill 2 to 3 meters in the regolith (the material that makes up the lunar soil), an essential ability to capture all the thermal variations depending on the depth.

Among the many projects, there is also a rover:

MoonRanger. Small, fast, autonomous, the mission of this newcomer will be to map in 3D and in high quality all the lands on which it passes. He will be able to explore the places up to 1 km from his control center.

PlanetVac and SAMPLR are two methods of sampling regoliths.

Lunar Demonstration of a Reconfigurable, Radiation Tolerant Computer System: computer equipment capable of withstanding the radiation of the sun (very strong on the Moon due to the absence of atmosphere), Heimdall is a system of cameras capable of making shots in very high resolution before, during and after the moon landing.

It could map the surface of the moon.

Donald Trump has granted a $ 1.6 billion extension for this return to the moon.

In its statement, NASA said: "The agency will use everything we have learned on the moon to prepare for a new giant leap: send astronauts to Mars".

Des astronomes révèlent la première image d'un trou noir ce mercredi10 avril. Pour la première fois dans l’histoire de l'humanité, des astronomes ont réussi à photographier un trou noir. L’image de ce monstre 6,4 milliards de fois plus lourd que notre soleil, situé au centre d’une autre galaxie, a été révélée ce mercredi 10 avril.  Cet exploit a été possible grâce à la coopération de scientifiques du monde entier . L’humanité a fait la connaissance de M87*: un disque orange entourant un cercle sombre, le tout un peu flou.

Situé à 53 millions d’années-lumière de nous, ce trou noir pèse 6,4 milliards de fois la masse de notre Soleil. Il mesure 40 milliards de kilomètres de diamètre. Plus grand que notre système solaire aussi lourd qu’une petite galaxie.

Mais malgré sa taille , saisir cette image constitue un réel défi tellement ce trou noir se situe loin de la Terre. C'est grâce à l’interférométrie c.a.d l'utilisation de plusieurs télescopes situés un peu partout sur Terre qu'une antenne virtuelle s'est crée : 7 télescopes du pôle sud aux États-Unis et une distance de 9 000 kilomètres ont été ainsi crée. Sur tous les sites il fallait en plus des conditions climatiques idéales.  Ce fut le cas 4 jours en avril 2017.

Mais que nous apprend cette image, au-delà de la prouesse ?

Il faut avoir en mémoire Albert Einstein et la théorie de la relativité générale. Cette dernière est la proposition faite par l'illustre physicien pour expliquer la gravitation.La présence d'une masse modifie la géométrie de l'espace-temps.

Si longtemps les trous noirs n’ont donc existé que par théorie, les équations permettaient d'en connaître leur existence. La première confirmation de leur existence fut la première détection des ondes gravitationnelles le 14 septembre 2015. C’est la fusion de deux trous noirs qui a été détectée.

« Ce qui nous intéresse, ce n’est pas tellement le trou noir mais ce qui se passe autour du trou noir, explique Jean-Pierre Lasota, chercheur émérite CNRS à l'Institut d'astrophysique de Paris. Et puis le trou noir contient des informations sur l’histoire et l’évolution de notre galaxie, et peut-être même sur la formation de cette galaxie. »

Nous attendons avec impatience la prochaine étape : l'obtention d'une image similaire d’un autre trou noir, mais pas n’importe lequel : le nôtre, Sagittarius A* qui se trouve au centre de notre galaxie, la Voie lactée !!!

Japan bombed an asteroid on Friday, April 5th. The Hayabusa 2 spacecraft successfully catapulted a small car on the asteroid Ryugu, one of the most promising vestiges of the formation of the solar system.

A world first successful to more than 300 million kilometers of the Earth. This is indeed the first collision experience in the world with an asteroid, say the researchers.

After several months spent in orbit about twenty kilometers from the star, the probe approached tonight 500 meters from its surface to drop a machine loaded explosive 2 kilos at a speed of 7,200 km / hour.

The impact made it possible to create an artificial crater in which Hayabusa will collect dust samples from the subsoil of the asteroid.

The objective of this operation is to have access to material under the surface of the asteroid to analyze the composition of the solar system at its creation.

The probe had to come close enough to Ryugu to fire his projectile without being hit by the debris of the explosion. It holds indeed valuable samples of the soil of the asteroid collected February 21 during a furtive contact with him.

Hayabusa 2 (literally "Peregrine Falcon 2") is a space mission of JAXA, the Japanese space agency, launched on December 3, 2014, to study the Asteroid Ryugu and bring a sample to Earth in December 2020.

The probe should land on the asteroid next May to collect soil samples.

India becomes the fourth nation to successfully bring down a satellite in low Earth orbit. For Prime Minister Narendra Modi, "it's a moment of pride for India". "India has achieved an unprecedented feat today," Narendra Modi said. India on Wednesday slammed a satellite into space with an ASAT anti-satellite missile during an exercise, Indian Prime Minister Narendra Modi said in a speech to the nation.

It has achieved this technological feat after the United States, China and Russia.

"Our scientists shot down a satellite in low Earth orbit at an altitude of 300 kilometers," the Hindu nationalist leader said in a televised address to the nation. "Our goal is to establish peace and not create an atmosphere of war. This is not directed against any country, "he said.

The operation, titled "Mission Shakti" ("force", in Hindi), lasted three minutes. "The satellite was a predefined target and was shot down by an anti-satellite missile," said the Hindu nationalist leader. An anti-satellite missile developed by the DRDO, the Indian agency responsible for the development of military technologies.

But according to experts this antisatellite technology has a major disadvantage in that the explosion in space projects into the Earth's orbit thousands of debris spinning at high speed that endanger other space objects. The use of a laser on the other hand would have made it possible to put out the instruments of a satellite by "glare", without touching its physical integrity.

According to India Defense Update, India began researching its space military capabilities after a Chinese test in 2007. Beijing had indeed demonstrated its ability to remove one of its satellites using a specialized missile .

The space competition between great powers is sharpening.

It should also be remembered that Narendra Modi is seeking a second five-year term in the legislative elections which will begin on April 11.

After having achieved its maiden flight, the Crew Dragon capsule developed by SpaceX returned to Earth this Friday, March 8th. Launched March 2 by a Falcon 9 rocket from the Kennedy Space Center in Florida, the Crew Dragon docked successfully at the International Space Station (ISS) the next day.

A first for a private vehicle for human space transport.

For this demonstration flight, the capsule was only passenger Ripley the model, a reference to the heroine of the movie Alien (1979) interpreted by Sigourney Weaver.

SpaceX's new Crew Dragon capsule on Friday (March 8th) left the comfort of its Earth orbit to dive into the atmosphere and land in the Atlantic, the ultimate and most dangerous phase of this Nasa demonstration mission.

Dragon returned unhindered and in one piece to Earth. SpaceX passed the exam:

demonstrate that the first US space shuttle vehicle since shuttles (1981-2011) is reliable and safe for astronauts.

It is the first private livable vehicle to have docked at the ISS.

It was also the first launch of a human ship from the United States in eight years.

A test for the thermal shield of the capsule

So far, the mission has been a success. The capsule was launched last Saturday by a SpaceX rocket from the Kennedy Space Center in Florida. She docked automatically at the International Space Station (ISS) on Sunday. Early Friday morning, briefly igniting its thrusters over the Sudan, 410 km above sea level, it broke off smoothly.

At 12:53 GMT, Dragon turned on his thrusters for a quarter of an hour, in order to "desorb":

to slow down and start the atmospheric reentry, which will test for the first time in real conditions its thermal shield. The landing a few hundred kilometers from the coast of Florida is scheduled to 08:45 (13:45 GMT). Four large parachutes, tested multiple times on Earth, will slow the fall.

Only a stoic dummy is on board (named Ripley in tribute to the heroine of the stoic series is on board (named Ripley in tribute to the heroine of the Alien film series).

"I would say that the hypersonic comeback is probably my biggest concern," said Elon Musk, the founder and boss of SpaceX, last Saturday.

A faultless one for SpaceX's Falcon 9 rocket, which successfully took off from the Kennedy Space Center in Florida, USA, and launched the new Crew Dragon capsule, designed to carry NASA astronauts in the near future.

The capsule should join International Space Station (ISS) in the day of Sunday.

She will stay there for five days before stalling and return to Earth next Friday.

For now, only a mannequin on board

Only a model named Ripley (a beautiful reference to the film Alien), equipped with a series of sensors, has been placed in the device that should eventually allow to transport real scientists.

It has been almost 8 years since the shutdown of the Space Shuttle Space Shuttle program that no spacecraft took off from the United States to join the ISS, so NASA had to buy its seats on board. of the Russian vessel Soyuz.

NASA is now focusing on SpaceX and its Crew Dragon capsule for astronaut transport to the ISS.

With this mission Elon Musk intends to prove the reliability of its system as well as its ability to safely transport NASA's future crews to join the ISS from US soil.

For the next launch will be astronauts Robert Behnken and Douglas Hurley on board.

Jim Bridenstine, NASA Administrator confirmed that the first manned test flight will take place before the end of the year.

Vaste success for the Japanese space agency Jaxa: on the night of Thursday 21 to Friday 22 February, the probe Hayabusa 2 landed on the asteroid Ryugu to collect samples before leaving. "The analysis of Hayabusa 2 data confirms that the sequence of the operation went well, including firing a projectile into the asteroid to collect its sample. The Hayabusa 2 spacecraft is in nominal condition. This marks the success of the landing of Hayabusa 2 on Ryugu, "comments the agency.

The Hayabusa 2 adventure began on December 3, 2014. The probe then left for a 3.2 billion kilometer long journey to reach Ryugu, which is 340 million kilometers from the Earth. It took him exactly three years and ten months to reach his destination. The return to Earth of Hayabusa 2 is expected in 2020 over Australia, in a desert area.

An incredible technical feat.

As expected, the Japanese spacecraft Hayabusa 2 only landed for a few seconds, the time to launch a projectile to clear dust and take a sample.

For this, the machine had to do what is called a "touchdown", that is to say, a touch-and-go at the surface.

Thus Hayabusa 2 (which means peregrine falcon) remained hovering a few tens of centimeters above the surface of Ryugu, for about five seconds. The only physical contact between the probe and the asteroid was a cone that was to collect surface grains projected into the air after firing a metal projectile made at a very high speed of 300 meters per second. After landing, the probe then took off.

Photos of Ryugu's surface, a very old diamond-shaped asteroid that dates from the formation of the solar system, taken by the probe show traces of the brief contact between the two.

The descent from Hayabusa 2 to the asteroid Ryugu began Thursday at 1:15 pm (4:15 GMT) late. But the probe finally came into contact with the asteroid nearly an hour earlier than announced, early in the morning in Japan, announced the Japanese Space Exploration Agency (Jaxa) who handled this delicate mission with extreme caution. The Japanese team was not in fact on its first try. A previous mission, Hayabusa 1, to the asteroid Itokawa, had collected dust from this small body, but at the cost of an incredible number of adventures.

Back on Earth at the end of 2020, these samples will inform scientists about the origins of the universe and the solar system.

In addition, the US Osiris-Rex probe, currently in the bosch of the asteroid Bennu, should return to Earth in 2023 with on board, hope NASA, the largest collection of space samples since the astronauts returned from the moon half a century ago.

SpaceX and his boss and founder Elon Musk are proud to announce the success of his new SpaceX rocket engine shown in action.

The SpaceX company, led by Elon Musk , has just tested its new rocket engine, the Raptor , which is intended for future rocket generations of the firm.

The project began in 2009 and the first experimental tests in 2016, SpaceX's ambitious Raptor has changed dramatically since its inception.

The test was successfully held on February 3 in Texas, on the facilities of the American company.

The Raptor will initially be used on the Big Falcon Rocket .

The craft will have 31 rocket engines for the first stage, and 7 for the second, enough to provide enough power to the rocket to fly to the moon, and even beyond.

The Raptor CRS-15 rocket engines have a bright future for SpaceX and the space launch market.

These should be used in all space operations of the company, including its upcoming space tourism activities to the Moon and Mars which represents a very promising market.

One thing is on SpaceX is preparing the future for a better control of space and travel in the universe.

"In my dream, ideally, by 2024 I will return to the ISS for a second mission," Thomas Pesquet said in an interview.

This dream is coming sooner than expected.

The Director General of the European Space Agency (ESA) Jan Wörner "has proposed to Thomas Pesquet to return very soon in space, for a flight whose date should soon be fixed with our international partners," said Tuesday the Minister of Higher Education, Research and Innovation Frédérique Vidal in her vows.

Thomas Pesquet is likely to leave at the end of 2020 or the beginning of 2021, subject to the agreement of NASA and the progress of the mission planning of the ISS. The youngest of the European astronaut corps, Thomas Pesquet, who will be 41 at the end of February, will have to resume intensive training very quickly.

He who flew for the first time in the International Space Station, for nearly 200 days, was able to share his experience through social networks.

"Beyond the tremendous scientific work he did during his flight, he managed to make every French player in this flight when before people were spectators," said Jean-Yves Le Gall, President of the Center National Space Studies.

And the ambitions of the French astronaut do not stop there. "I would like to be among the first to go to the future station around the moon," Thomas Pesquet said enthusiastically.

China has just completed the first moon landing on the dark side of the Moon.

The rover of the Chang'e 4 mission, which left the Earth on December 8, landed safely at 10:26 am Beijing time, the Chinese National Space Administration said in a press release.

It landed in the Von Kármán crater at 177.6 degrees east longitude and 45.5 degrees south latitude. 186 kilometers wide, this crater is located in the Aitken Basin, an old impact crater with a width of 2,500 kilometers and a depth of 12 kilometers.

A technological feat

It is a technological feat for China, the first country to make a moon landing on the hidden side.

The hidden face is mountainous and rugged, dotted with craters, while the visible face offers many flat surfaces to land. Chang'e 4 - named after the goddess of the moon in Chinese mythology - was sent to a region of the south pole of the lunar body, the Aitken Basin, whose terrain is complex and steep.

Neither the United States, nor Russia, let alone Europe, have explored this unknown part of the moon from the ground, even though probes in orbit around the moon have overflown it and mapped its entire surface.

Another challenge is to be able to communicate with the lunar robot: the hidden face is always oriented in the opposite direction to the Earth, there is no direct "line of sight" to transmit the signals, except to install a relay .

To this end, Chinese engineers had launched in May a satellite called Queqiao ("The Bridge of the magpie"), positioned in lunar orbit, to relay orders and data exchanged between the Earth and the module.

China will therefore use the Queqiao relay satellite in orbit around the second Lagrange point (L2) of the Earth-Moon system located approximately 455,000 kilometers from our planet.

Like Chang'e 3, the Chang'e 4 rover has a panoramic camera and a radar to probe the basement. It also carries an imaging spectrometer in the visible and near infrared.

A great scientific interest

This unknown region of the Moon is of great scientific interest: it could contain exposed materials from the upper mantle of the Moon.

Thus the rover will study the impact of solar winds on the lunar surface for at least three months.

An experiment in the biological field, which 28 Chinese universities have developed, will also be conducted.

D seeds of Arabidopsis, potatoes, tomatoes will be planted to see if they emit oxygen through photosynthesis.

The rover also sent his first images that are historical.

Unpublished clichés because the first taken from the surface of the hidden side of the Moon.

The stated ambitions of China

With this achievement, Beijing asserts itself as a great space power but the Chinese space agency, at the forefront of robotic exploration of the Moon, does not intend to stop there.

After Chang'e 4, China plans another mission on the hidden side but to bring back lunar samples, which has not been done since NASA's inhabited Apollo mission.

Three other robotic missions are also planned for the lunar poles.

Beyond these robotic missions, the Asian giant, which also unveiled in November 2018 a replica of its first major space station ("Heaven Palace"), plans to make it operational around 2022.  It would become the only station to evolve in space after the planned 2024 retreat of the International Space Station (ISS) - which combines the United States, Russia, Europe, Japan and Canada.

Moon, advanced post for space

Any country that begins space exploration begins with the Moon, an accessible destination, while Mars is far away and expensive. The moon now appears as the first step for space habitats

NASA, too, is studying the idea of ​​a "lunar orbit portal" (the former "Deep Space Gateway"), which would turn the Moon into an outpost of conquest of other planets. A lunar outpost that could serve as a "relay point" leading to Mars..

"We are witnessing a democratization of space, with the arrival on the market of small and cheap satellites and launchers and more and more countries are equipping themselves. We are in a competition for access to space ", explains General Michel Friedling

On Wednesday 19 December 2018, at precisely 17h37mn14s, CSO-1, a military optical observation satellite, was placed in orbit at 800 km altitude. It is the first of a constellation of three identical 3.5-ton satellites, intended to replace the Helios 1 and 2 series of systems, which have been monitoring space since 1995 on behalf of the DGA (Directorate General armaments) and the Ministry of the Armed Forces.

Since October 2011, Soyuz launchers have been fired from the Soyuz Launch Pack (ELS) located in the commune of Sinnamary, 27 km from Kourou, and about 13 km from Ariane installations. Every year, at least four Soyuz shots are fired from the Guyanese site. Eight have already taken place this year and the last one has just been realized this Wednesday afternoon with the French observation satellite CSO-1 (Optical Space Component).

This satellite, which will provide very high resolution images, will be joined by two others, in 2020 and 2021, to form a constellation to replace the current French military observation satellites Helios 2A and 2B. Expected to last 10 years, the constellation will cost 920 million euros, and 1.4 billion euros with the ground segment.

This latest Arianespace launch of 2018 is of major importance for the French defense. It is part of the space projects of the French Military Planning Act (LPM) 2019-2025 which provides for a significant budget of 3.6 billion euros for the defense space.

These shooting satellites ensure the operational needs of the various armies in terms of intelligence, whether it is the surveillance of risk sites, compliance with international treaties or the global strategic intelligence function.

The information collected by these observation satellites on the geographical environment makes it possible to prepare the missions as closely as possible. Thus these satellites made it possible to locate the caches of Daech in the Levant.

"Space intelligence also allows for political autonomy," said General Michel Friedling, commander of the Joint Space Command. "In 2003, when the war entered Iraq, we had our own images. Which allowed to question the American speech, and from there, our authorities decided not to intervene "

In a competition for access to space, a new field of confrontation, innovations in military defense are indispensable.

The Soyuz MS 11 rocket, currently the only means of transporting crews to the International Space Station (ISS), was successfully launched on Monday, 3 December, from the Baikonur Space Center in Kazakhstan.

It landed at 18:40 (Paris time) after taking off unhindered at 12:30, or 6:30 after the launch as planned. On board the crew of Expedition 58, composed of three astronauts:

David Saint-Jacques of the Canadian Space Agency, Ana McClain of NASA, and Russian cosmonaut Oleg Kononenko of Roscosmos. The three scientists took off for a six-and-a-half-month mission in orbit 400 kilometers above the Earth. The current crew of Sergei Prokopyev, Alexander Gerst and Serena Auñon-Chancellor are due back on December 20th.

This flight was a test for the Russian space industry, half a century after the beginning of the space conquest marked by the historic flight of Yuri Gagarin,

Indeed, on October 11, the rocket carrying the American Nick Hague and the Russian Alexey Ovitchinin had suffered a failure two minutes after takeoff. Added to this failure was another incident, namely the discovery of a leak in August on one of the Soyuz vessels stationed aboard the ISS.

Although Soyuz remains one of the safest space programs in history, doubts have been expressed about the Russian space industry, which has been plagued by failures in recent years. In the United States, which has invested $ 100 billion in 28 years in the Space Station, NASA leaders and politicians are worried about their reliance on a single space transportation system.

Vladimir Vladimir Putin asked his agency in July "to drastically improve the quality and reliability of Russian spacecraft and launchers". Roscosmos is facing rising cost problems, insufficient technology and lack of skilled labor.

The Russian space industry is struggling to replace an aging workforce with young engineers and technicians with unattractive salaries. Added to this is corruption and embezzlement. Since 2014, 140 investigations have been opened following embezzlement around the construction of the Vostochny Cosmodrome.

If Russia had until then had the monopoly of these trips since 2011 and the shutdown of the American Space Shuttle, it should face in 2019 the competition of "space taxis" SpaceX and Boeing.

After almost six months of travel in space and 484,773,006 kilometers traveled between Earth and Mars, NASA's InSight probe landed on the Red Planet on November 26, 2018.

Launched by NASA on May 5, 2018 as part of the Discovery program, the probe will study the internal structure of the red planet, including evaluating its seismic activity.

Hardly had the robot InSight begun to send signs of presence to the Earth, probe has sublime pictures of its environment.

More specifically, InSight will aim to study the internal structure of Mars. Like the other three terrestrial planets - including the Earth - the red planet is formed by the gradual accretion of rock bodies, until its mass and temperature become sufficient for the process of planetary differentiation to take place.

As Mars does not have tectonic plates, its internal structure has not undergone any major changes since the formation of the planet and must have retained geophysical signatures of this process of differentiation.

By analyzing the different parts of its structure - crust, mantle and core - InSight should be able to collect important information on how the planets were formed 4 billion years ago.

Scientific operations will not begin right away.

Seis seismometer and HP3 heat flow sensor must be installed on the ground using a robotic arm. The maneuver is not planned for two to three months.

Two European instruments aboard InSight will allow to analyze the internal structure of Mars

1 ° Seism seismometer (Seismic Experiment for the Interior Structure), developed by the Institute of Earth Physics of Paris under the authority of CNES, which is a three-axis seismometer of about 30 kg, including seismic sensors and temperature. It will study the Martian tectonic activity and make seismic surveys.

2 ° HP3 Heat Flow and Physical Properties Package developed by the German Space Agency. It is a thermal probe that will sink up to 5 meters deep below the Martian surface. Its role is to measure the heat flow released by the Martian nucleus, in order to better understand its evolution.

These tools will be put in place in sixty days while an additional seven weeks will be necessary for the thermal probe to sink into the Martian soil.

Good luck to InSight who deployed its two 2.2 m wide solar panels and will pierce the Martian depths, listening to the heartbeat of Mars. .

Nine month of journey to reach a planet still inaccessible for man. NASA, the US space agency, has just announced its new goal: send men to the planet Mars in 25 years or 2,043.

"With the current budget or a slightly increased budget, it will take 25 years to address these issues," said retired astronaut Tom Jones. But what problem still unresolved!

You must know that Mars is located 225 million kilometers from the Earth, which requires nine months of travel.

And a move that is not without risk!

Scientists warn about the dangers that duration might represent this mission. According to them, an extended stay in space could degrade the blood vessels of the retina and thus alter the vision of the cosmonauts. They also warn against a loss of calcium in the bones, also caused by a period spent too long in zero gravity.

"We need to start focusing on some key technologies right now," said Jones. And for this former astronaut, the solution is simple: it is necessary to create nuclear propulsion systems to shorten the travel time.

NASA must find not only a solution to reduce travel time but also to avoid radiation. During the journey, astronauts could suffer as much as during an entire career.

"We do not yet have the solution for the protection of cosmic rays and solar flares," acknowledged Tom Jones. NASA experts have begun to work on technologies to develop to carry out this mission with the minimum of risk for the health of their men.

While waiting to send men to Mars, NASA continues to exploit the data collected by the Curiosity robot that has been on the planet since 2012.

Sent May 5, 2018, the probe InSight, created by the American space agency, must land on November 26 on the red planet.

It will notably study the internal structure of Mars to better understand how the rocky planets of the solar system are formed.

A new rover must be sent to Mars in 2020 to determine this time if the planet is habitable.

China has a new symbol of its ambitions in space at the Zhuhai Air Show. It unveiled Tuesday, November 6 a replica of its first major space station (CSS), which should be launched around 2022 with the goal of succeeding the International Space Station (ISS).

The craft is surmounted by a mannequin in cosmonaut's attire and flanked by the national red and yellow flag constituting one of the main attractions of the show.

The lifetime of the CSS, also called Tiangong ("Heavenly Palace"), is estimated at 10 years. It would then become the only station to evolve in space after the planned retirement in 2024 of the international space station associating United States, Russia, Europe, Japan and Canada.

The Chinese space station will consist of three parts: a main module nearly 17 meters long - for living and working space - and two additional modules for scientific experiments. Three astronauts will be able to live permanently on the machine weighing at least 60 tons and equipped with solar panels. They will be able to carry out research in science, biology or microgravity.

China also announced in May with the UN Office for Space Affairs that its station would be open "to all countries" to conduct scientific experiments. Forty projects from twenty-seven countries and regions Institutes have been submitted by universities and public and private companies.

The European Space Agency (ESA) is already sending astronauts to train in China, with the goal that they will one day fly aboard the Chinese station.

Beijing is investing billions of euros in its space program, led by the army shipping satellites in orbit on its behalf (Earth observation, telecommunications, Beidou geolocation system) or for other countries. She is also planning to send a robot to Mars and humans to the Moon.

The Middle Kingdom, aware of commercial and military issues, will become one of the great powers of space alongside Russia, Japan and India.

"Attempting to listen to your neighbors is not just unfriendly. It's called an act of espionage "

The French Minister of the Armed Forces, Florence Parly, Friday accused Russia of having committed in 2017 "an act of espionage" against the French-Italian military satellite Athena-Fidus to try to intercept secure communications.

Has Russia tried to spy on a Franco-Italian military satellite?

The minister of the Armies asserts it, since the Cnes.

Florence Parly in a speech on the space defense sector indicated that in 2017, "while Athena-Fidus continued its rotation quietly over the Earth, a satellite approached him, up close, a little too close . However, "this satellite with big ears is called Louch-Olymp, Russian satellite well known but a little ... indiscreet," she added.

Launched in 2014, Athena-Fidus provides high-speed satellite telecommunications services for the French and Italian military forces, as well as for civil security in the same two countries.

Satellite launched in February 2014, Athena-Fidus "consists of two payloads French and Italian," says CNES on its website. It weighs a little more than 3,000 kg and its charges "offer 23 Ka and EHF broadband transponders and 12 different covers: national metropolitan covers, mobile covers, [...] global coverage". It was "built for a lifetime of 15 years in geostationary orbit".

"So much so that we could have thought he was trying to capture our communications," she added. But "trying to listen to your neighbors is not just unfriendly. It's called an act of espionage.

France has fallen behind.

" This big-eared satellite is called Louch-Olymp, it's a well-known but somewhat indiscreet Russian satellite, " she continued. "We had seen it happen, and took the necessary measures. We watch him closely, and we have observed that he continues to actively maneuver the following months with other targets, but tomorrow, who says he will not come back to one of our satellites? She asked herself.

The United States has recently denounced "the very abnormal behavior" of a "space object" deployed by Russia in October 2017. The French Minister regretted for its part that France did not become aware of a militarization of space. " For some time now, as our neighbors have partly changed the nature of space, what have we done? Not much, she said. Not enough in any case. No, we are not protected against these threats. No, espionage and offensive acts, it does not happen only to others. Yes, we are in danger, our communications, our military maneuvers as our dailies are in danger if we do not react , " warned the French Minister of Armies. She also pointed out that " other very large space powers deploy intriguing objects into orbit, experiment with potentially offensive capabilities, conduct maneuvers that leave little doubt about their aggressive vocation".

Critical space defense issues.

It is important to know that space defense issues are becoming crucial. Indeed in the magazine Military Zone are raised the risks. "This is not the first time the risk of a cyberattack targeting satellites is mentioned.

In 2009, the "hacker" Adam Laurie demonstrated that it was possible to intercept a flow of information transmitted by satellite with a computer, a Dreambox type decoder and some software. " Says Pascal Lagneau.

"Then, five years later, a study by IOActive highlighted that the flows of telecommunications satellites could be hacked because of" multiple high-risk vulnerabilities "present in the software integrated into the satellite access terminals. He adds. For example, a group of Chinese hackers named "Thrip" is accused by the United States of spying on geospatial telecommunications and imaging companies and defense organizations in the United States and South Asia. -East. The cyber threat therefore also joins the threat to space activities.

"Space systems are likely to be attacked, like all other systems, and are protected. But, by nature, their protection, in orbit, is materially more difficult than that of other sovereign systems. We have observed specific cases of so-called 'foragers' and sovereign satellites. We have observed specific cases of satellites known as 'browsers', and it protects against possible misdeeds by conventional methods of coding and shielding against laser fire and electromagnetic charges , " explained Jean-Yves Le Gall, president of the National Center for Space Studies [CNES], during a parliamentary hearing.

These threats to the exo-atmospheric space were highlighted by the Strategic Review published in October 2017. "The progress of space rendezvous techniques, robotics and electric propulsion capabilities make it possible to repair, refuel and fuel or even de-orbiting spacecraft. Under the guise of civilian targets, states can therefore openly fund potentially anti-satellite technologies. These would allow the commissioning of tools whose actions would be much more difficult to detect, track, assign and counter than more conventional exo-atmospheric actions (missiles, lasers, jammers ...) " , can we read there.

The Law of Military Programming [LPM] 2019-25 that President Macron promulgated, takes into account this "arsenalisation" of space.

While in the United States, it is now a question of creating a "space force", President Emmanuel Macron has indeed announced his intention to define for France "a defense space strategy" . It makes space a national security issue. The space is "essential for our operations" and "by the incredible potentialities it offers but also by the conflictuality that it arouses" , it "is [...] a real stake of national security" , affirmed Mr. Macron .

A Ministry of the Armed Forces working group is expected to make proposals on the subject by November.

On the evening of Friday, July 27, the moon will be totally eclipsed and the bright Mars will appear visible side by side to the naked eye, southeast of the sky.

The full moon at sunset is partially hidden by the shadow of the Earth, the Moon will plunge completely into the Earth's shadow and present us with a deep coppery hue.

In space, the Sun, the Earth and the Moon have aligned themselves perfectly and the lunar disk is gradually diving into the shadow of the Earth.

At 9:30 pm, Paris time (universal time +2 hours), the full moon is fully immersed in the shadow cone of our planet and its face is a coppery color.

At 22 h 20 min, in a darker sky and when the full moon reaches the deepest part of the Earth's shadow, the bright orange dot of Mars is visible at 6 degrees below it.

An hour after the departure of the Sun, in a twilight sky already dark, we will observe this extremely brilliant point of the planet Mars, just beautiful next to the Moon totally eclipsed.

This planet is in opposition and it shines as never in the last fifteen years:

superb heavenly show!

It is also aligned with the Sun and the Earth, but it is nearly 58 million kilometers from us, well beyond the end of the shadow of our planet.

From 23 h 13 min the Moon sketches out of the shadows.

At 0 h 19 min, July 28 is the full moon fully out of the shadows to return there on January 21 for an upcoming total eclipse.

At your telescopes!

Astrobiologist Jennifer Eigenbrode of the US Space Agency's Goddard Center said, "This is a significant step forward as it indicates that organic matter is being preserved in the harshest environments of Mars," adding, "Curiosity has showed that the crater Gale was habitable about 3.5 billion years ago, with conditions comparable to those of the Earth in formation, where life evolved at this time ".

Recall that the Curiosity rover rolls since August 2012 on the sedimentary layers inside a Martian crater called Gale (in honor of a nineteenth century Australian amateur astronomer). And finally here he is who has just delivered a discovery of the most important!

Amazing organic molecules have been discovered by the Curiosity rover in sedimentary rocks dating back about 3.5 billion years. These rocks have been deposited in a lake considered one of the most difficult areas of Mars at a time when life could flourish. The researchers also know a little more about the atmosphere of Mars with the discovery of traces of methane.

Curiosity seems to have also confirmed the presence of seasonal variations of methane in the Martian atmosphere. But this gas, often a sign of the presence of life, comes from the planet itself and could be contained in ice sheets below the surface.

If this is a step forward in the search for life on the red planet, it does not yet suggest the discovery of life on this planet. Indeed samples of organic matter may have an abiotic origin, come from geological formations similar to coal, or a meteorite.

In 2014, organic matter in small quantities had already been found by Curiosity. If that does not mean that life is present, according to Sanjeev Gupta, professor of SVT at Imperial College London (UK) and co-author of the study, "organic compounds are the building blocks of life ".

These two discoveries however evoke the potential life existing or passed on the Red Planet. These types of molecules turn out to be constitutive elements to the appearance of life. And there are two possibilities concerning their origin: either it is an exclusively physical process, or these molecules mean that there has been a life on Mars in the past.

Organic molecules and a potential life on Mars?

Knowing that these organic molecules appeared at the same time as liquid water on Mars and that these two elements together triggered life on Earth, the second possibility is quite probable. Added to this is the presence of methane, another potential indicator of life on Mars.

Indeed, it is the seasonal variability of this methane that intrigues scientists, especially as a peak occurs in the summer. For our Earth, this phenomenon is associated with a biological process. But is it the same for Mars? No one knows for now ...

Methane and organic molecules could be biosignatures of life forms but their origins could also be abiotic.

Let's hope that NASA's Rovers March 2020 and ESA's ExoMars 2020 will land on the red planet to elucidate this intriguing new find.

The scientists looked at snapshots taken by NASA's 2006 New Horizons spacecraft, which flew over Pluto in 2015. It is about -230 degrees and is the farthest dwarf planet in the solar system. . You may have guessed it, it's about Pluto.

And we now know more about the surface of this planet. According to snapshots taken by the New Horizons spacecraft, which flew over Pluto in 2015, it would be covered with dunes of methane ice.

"The probable source of the dune's grains is the methane ice carried by the winds from the mountains," the scientists explain in an article published Thursday in the journal Science. "But we can not exclude that it is nitrogen ice."

Surprising discovery insofar as the atmospheric pressure at the surface of Pluto is 100,000 times lower than that of the Earth. As a result, astronomers thought that it was too weak for winds to form.

"The probable source of the dune's grain is the methane ice carried by the winds from the mountains," scientists say in an article published Thursday (May 31st) in the journal Science. The winds would blow at an approximate speed of 30 to 40 km / h. Weak winds, but so is gravity.

The dunes themselves are spread over an area about 7 km long.

Besides Pluto, it was already known that Mars, Venus or Saturn's great moon, Titan, had dunes, says lead author Matt Telfer, a professor at the University of Plymouth (United Kingdom). "We knew that everything in the solar system with an atmosphere and a solid surface had dunes, but we did not know what we would find on Pluto."

The dunes are probably young, geologically. They would have formed in the last 500,000 years.

"But it turns out that Pluto, while being 30 times farther away from the sun than the Earth, has similar characteristics to Earth's," according to the scientist.

China came to launch on Monday a satellite to observe the hidden face of the moon, photographed since 1959 but never explored.

The hidden face of the Moon refers to the hemisphere of the lunar body that is not visible from Earth.

She has been photographed since 1959 but has never been explored.

This relay satellite responsible for ensuring communications between the Earth and a small robot should be deployed on the far side of the Moon in 2018, according to the Chinese Space Agency.

That's why a Long March-4C rocket took off at 5:28 am local time (2128 GMT Sunday) from the Xichang launch pad (south-west) with the Queqiao satellite on board, the National Space Agency said.

Upon the arrival of the remote-controlled robot on the Moon, the satellite will be at a place where it can exchange with the Earth, while having in its line of sight the hidden face of the Moon.

"This launch is a crucial step for China to become the first country to send a probe able to smoothly glide and explore the dark side of the moon," said Zhang Lihua, head of the satellite project.

This is a second Chinese remote-controlled vehicle on the moon after the launch in 2013 of a rover named "Jade Bunny" which has surveyed the lunar surface for 31 months, well beyond its expected life.

It is expected that another robot (Chang'e-5) will be sent to the Moon in 2019 to collect samples and bring them back to Earth.

China invests billions of euros in its space program, coordinated by the army. The country aims to have a space station inhabited by 2022, and eventually send humans on the moon.

The take off took place at dawn on Saturday. Look at the images.

NASA successfully launched the InSight probe for Mars on Saturday. According to the US space agency, the red planet will be subjected to the first "in-depth verification of its vital functions since its creation 4,500 million years ago".

"Three, two, one, take off!" said a NASA commentator and the unmanned mission moved into the overcast sky. The takeoff took place before dawn, at 4.05 local time (8.05 Buenos Aires) from Vandenberg Air Force Base in California, United States. Aboard an Atlas V rocket - equivalent in height to a 19-storey building

The InSight robot must be placed on Mars on November 26th. The mission will last two years and will cost $ 933 million. It's the first to take off from the west coast of the United States to another planet.

Historical Odyssey: For the first time, NASA will explore the heart of Mars with robots

In fact, the launch was planned for 2016, but it had to be postponed for two years due to a leak in two of the analytical instruments. "It's like playing golf in New York and putting the ball in a hole in California is the level of precision we need," said Jim Green, NASA's chief scientist, during the broadcast. direct.

InSight will allow the analysis of the heat flux of Mars and will measure the tremors that occur during earthquakes. Researchers are convinced that new knowledge about a rocky planet like Mars will directly contribute to future discoveries about the formation of the Earth.

At the same time, he seeks to expand data on the internal conditions of this planet, because, for example, understanding the temperature of Mars is crucial to send people to the red planet in 2030, as expected.

Its name, InSight, comes from inland exploration using seismic surveys, geodesy and heat transport. "March, I'm going, six months and I hope I'll get to the red planet , " reads the InSight Twitter account.

If everything goes as planned, your trip will be 400 million kilometers.

The difference with Curiosity

Unlike the Curiosity mobile, InSight can not travel on the Martian surface. It will remain stationary at a point to study the vital functions of the planet.

To measure temperature, the German Aerospace Center (DLR) has developed a device that will automatically drill up to five meters in Mars soil and record at different depths.

The InSight mission responds to a craving for planetary researchers: "having a geophysical observatory on a planet similar to Earth," said Tilman Spohn of the DLR in a statement.

"Mars is an ideal goal: it can be well achieved and it is an ideal object of comparison with the Earth," he added.

How does InSight work?

Green said the experts already know that Mars presents earthquakes (which could technically be called martemotos), avalanches and meteorite falls. "But how is Mars subject to earthquakes?" This is basic information that we need to know as human beings who are exploring Mars, " he said.

InSight collect data using three instruments: a seismometer, a device to accurately locate the Mars probe oscillates around its axis of rotation and a flow sensor heat is inserted 5 meters below the surface of Mars.

But its key instrument is the seismometer, manufactured by the French Space Agency.

Once the probe is placed on the Martian surface, a robotic arm must be placed directly on the ground.

"For us, InSight is perhaps not the best, but a very important mission because we are going to hear the beating of Mars with the seismometer we put on board," Jean-Yves Le Gall, CNES President of France ( says CNES), in a NASA television interview after the launch.

The second important element is the heat detector that will be placed in the basement. Called Heat Flow and Physical Properties Package, it was produced by the German Space Agency with the participation of its Polish counterpart.

The instrument will be introduced between three and five meters below the surface of Mars, at a depth fifteen times greater than that reached in any previous mission.

The temperature at the landing point is freezing and should be between -100 and -20 degrees Celsius. During the summer day at the equator of Mars, the temperature reaches about 20 degrees Celsius, but then drops to -73 degrees at night.

"We must be able to survive in these conditions as human beings living and working on Mars," Green said.

The battery powered, solar powered sensor is designed to operate for 26 months from Earth - or a year on Mars - a period during which it is expected to detect about 100 earthquakes.

"I wish it would be longer than expected," said Tom Hoffman, InSight Project Manager at NASA's Propulsion Laboratory.

"There is nothing usual about going to Mars, especially landing on Mars," said Stu Spath, Lockheed Martin Space InSight Program Manager.

Favorable launch windows for Mars occur only every two years.

The "Marcos", other satellites

Aboard the Atlas V rocket, two small cube-shaped satellites accompanied the InSight: the CubeSats. They are part of the Mars Cube One mission (MarCo) and are prototypes of miniaturized technology, more economical than the one usually used in major space missions.

The MarCo A and MarCo B satellites, the first CubeSats orbiting a planet other than Earth, will follow the path to Mars separated from InSight. But if they manage to reach the Red Planet in time, they will participate in the retransmission to Earth of the ship's signals after landing.

The engineers responsible for the mission nicknamed them precisely Wall-E and Eva, as they explained in the live broadcast of the InSight version.

On Saturday, May 5, 2018, the probe will be propelled towards the red planet aboard an Altas V rocket.

The NASA probe is due to take off on Saturday to Mars to reach its final destination in November.

The Mission InSight mission is to study the tectonic activity of the star to better understand how the rocky planets are formed.

On board, a seismometer developed by CNES.

As scheduled at 13:05 (Paris time) the craft was launched from the Vandenberg base of the US Air Force, near Santa Barbara, California.

Once there, the NASA spacecraft will listen to "beating" the heart of Mars by measuring its seismic activity to better understand the history and structure of this planet.

"We know that March has been liveable ," said Jean-Yves Le Gall, director of CNES.

It was Mars Express, which was launched in 2003, which showed it. There was water, the atmosphere, the oceans and then all that disappeared. Today Mars is a frozen desert, probably toxic on the surface.

We want to understand why. "

These changes could be due to the modification of the magnetism of Mars.

As part of the Discovery program's geophysics mission, the spacecraft will study two years of tectonic activity on the Red Planet using three instruments:

a seismometer (SEIS), developed by the French National Center for Space Studies (Cnes), a device to accurately locate the probe while Mars oscillates on its axis of rotation (RISE) and a heat flow sensor inserted at 5 meters in the Martian basement (HP3) .B

"If InSight is a success, we will know in 2 or 3 years why the oceans have disappeared, why magnetism has evolved.

From there, we will have one more clue that will help move forward. "

Good Mission!

British astrophysicist Stephen Hawking, the most famous contemporary scientist - compared to Albert Einstein or Isaac Newton - died Wednesday at the age of 76 at his home in Cambridge, North London, announced his children. "We are deeply saddened by the death of our beloved father today , " said his children, Lucy, Robert and Tim, in a statement. " His courage and tenacity, his genius and his humor, have inspired people around the world," said his children.

He has been suffering from paralytic degenerative disease, amyotrophic lateral sclerosis (ALS) or Charcot's disease since the age of 21, and has challenged the idea that he only had a few years to live. Paralyzed all the same it only communicated thanks to a computer and a synthesizer of voices.

In his autobiography, The Brief History of My Life , we learn that the announcement of his illness at 21 years had triggered in his passion for mathematics and physics at age 17 at Oxford University his desire to make scientific discoveries "When you face the possibility of dying young, you understand that life deserves to be lived and that there are many things to do," he says in his autobiography.

He then concentrated his life exploring the secrets of the universe. His work focused on bringing the theory of relativity and quantum theory closer together in an attempt to explain the creation of the Universe and how it works. His ideas on black hole physics, the Big Bang and astrophysical singularities that have resulted in more than 130 research papers have revolutionized the understanding of these enigmatic bodies.

In 1974, at the age of 32, he became one of the youngest members of the Royal Society, the most prestigious scientific institution in Britain. In 1979, Hawking was named professor of mathematics at the University of Cambridge.

"My goal is simple," he said one day. "It's the total understanding of the Universe", "to understand why he is as he is and why he exists" . And this understanding, he wanted to share with the Boeotians that we are by the publication of a global bestseller, A brief history of time , published in 1988 and sold several million copies.

In cinema, a biopic directed by James Marsh had been devoted to him in 2015, "A marvelous history of time".

The tributes of the scientific community multiplied on the announcement of his death. "Professor Hawking was a unique being who will be fondly remembered not only in Cambridge but around the world," said Stephen Toope, vice-president of Cambridge University, where Stephen Hawking had studied and worked. . "His outstanding contribution to scientific knowledge, mathematics and extension leaves an indelible contribution." On Twitter, NASA praised "a renowned physicist and a science ambassador". "His discoveries have opened up a world of possibilities that we and the world continue to explore," said the US Space Agency.

British Secretary of State for Veterans Tobias Ellwood said Stephen Hawking was "an inspiration to all of us, no matter what our situation, to reach the stars".

Hier, mardi 6 février 2018, la fusée la plus puissante du monde, la Falcon Heavy, de Space X, a effectué son premier vol historique.  Le lancement avait cependant été reporté par deux fois dans l’après midi.

Elon Musk a tweeté à 20 h 46 GMT (19h30 heure française) un message accompagné d’une vidéo de Falcon Heavy.

Selon lui, « la mission s’est déroulée aussi bien que l’on pouvait l’espérer, et le tir a été réussi ».

La conquête de l‘Espace va désormais entrer dans une nouvelle ère.

La Falcon Heavy va en effet ouvrir une nouvelle voie qui devrait permettre de transporter des humains vers la Lune ou Mars.

Les 27 moteurs de cette super fusée se sont allumés tous en même temps pour générer une poussée de 2500 tonnes, soit l’équivalent de 18 Boeings 747, à la verticale.

Une explosion géante a été vue sur le pas de tir de la base spatiale de la Nasa en Floride.

Elon Musk , le milliardaire sud africain avait au préalable décidé de remplacer la charge utile (60 tonnes) de la fusée  par son Roadster Tesla Rouge Cerise, lequel a été propulsé vers l’espace  puis mis sur orbite.

La Tesla Rouge Cerise était cachée dans le capuchon de la fusée.

Un mannequin, qui avait été équipé d’une combinaison rouge elle aussi et baptisé Starman et qui avait été installé au volant de la Tesla diffusait la chanson de David Bowie, Space Oddity. De son coté, le tableau de bord de la Tesla Rouge affichait « D’ont Panic », la référence très galactique de Douglas Adams (extrait de son Guide du Voyageur).

Le clou du spectacle : l’atterrissage en retour et en douceur,  de deux des propulseurs qui se sont posés comme des plumes sur le sol. Le troisième, en revanche, a sombré dans l’Atlantique, plongeant à une centaine de mètres de la barge ou il devait se poser ; Selon Elon Musk, l’engin aurait apparemment pénétré à 480 km/h dans l’eau.

Ariane 5 confirme sa fiabilité après son tir avorté début septembre .Le lancement avait été annulé le 5 septembre 2017 après une anomalie observée dans les ultimes secondes précédant le décollage.

Cette fois le 29 septembre 2017, un peu moins de 30 minutes après son décollage, Ariane 5 s’est séparée du satellite de près de 6,5 tonnes Intelsat 37e.

Et un peu plus de 47 minutes après s’être arraché du sol guyanais, Ariane 5 s’est séparé du satellite BSAT-4a.

Un succès puisque une fusée Ariane 5 a placé en orbite deux satellites commerciaux, Intelsat 37e et BSAT-4a, vendredi 29 septembre 2017 après un décollage du Centre spatial guyanais de Kourou, a annoncé Arianespace dans un communiqué.

En effet Ariane 5 a réussi sa mission mettant sur orbite depuis le Centre Spatial Guyanais deux satellites de télécoms :

Intelsat 37e pour l'opérateur américain Intelsat (près de 6,5 tonnes) et BSAT-4a, un satellite de 3,52 tonnes dédié à la télévision numérique pour le constructeur SSL (Space Systems Loral) dans le cadre d'un contrat clé en main au profit du japonais Broadcasting Satellite System Corporation (B-SAT).


Fabriqué par Boeing, Intelsat 37e est le 59e satellite d'Intelsat à être lancé par Arianespace depuis la mise en orbite d'Intelsat 507 en octobre 1983.

Deux autres satellites Intelsat figurent dans le carnet de commandes d'Arianespace (Intelsat 39 et Horizon-3e).

"Nous sommes très heureux de la confiance renouvelée d'Intelsat qui, un peu plus d'un an après le lancement double d'IS-33e et de IS-36 et sept mois après celui d'Intelsat-32e/SKY Brasil-1, nous a choisis pour la mise en orbite d'IS-37e, le satellite le plus puissant de sa flotte EPICNG", a souligné le PDG d'Arianespace, Stéphane Israël.

BSAT-4a, quant à lui, est le neuvième satellite lancé par Arianespace pour B-SAT.

Depuis la création de B-SAT, Arianespace a lancé tous les satellites de l'opérateur Japonais.

Il s’agit du neuvième succès de l’année pour Arianespace, la société qui commercialise les lancements. Et du 81e succès consécutif pour une Ariane 5, le cinquième en 2017

« Les découvertes faites figurent parmi les plus époustouflantes en science planétaire », avait expliqué mercredi devant la presse Linda Spilker, principale scientifique de la mission.

Cassini , c'est fini. La sonde américaine a lancé son dernier message et s'est désintégrée vendredi après avoir réussi à transmettre des données jusqu'à la dernière seconde.

Après vingt années dans l’espace, l’ultime signal de la petite sonde a été capté par le centre de contrôle du Jet Propulsion Laboratory (JPL), en Californie. Ce dernier souffle électronique aura mis près d'une heure et demie à parcourir le milliard de kilomètres et demi qui nous sépare de Saturne.

Le vaisseau de 2,5 tonnes, lancé en 1997 a mené une exploration scientifique durant treize années de SATURNE  la grande planète gazeuse, de ses anneaux et de 19 de ses lunes.

« Le signal a été perdu…. c’est la fin du vaisseau spatial », a dit un des ingénieurs du centre de contrôle, selon les images de la NASA retransmises en direct.

« J’espère que vous êtes tous très fiers de cet accomplissement extraordinaire, félicitations à tous pour cette mission incroyable », a déclaré Earl Maize, le responsable de la mission Cassini en s’adressant à toute son équipe.

Pendant son plongeon final, Cassini a continué de prendre des mesures et à les transmettre en temps réel vers la Terre. Cassini avait pour mission de «respirer» quelques molécules d'atmosphère pour en déterminer la nature. «Les dernières secondes de Cassini pourraient à elles seules fournir assez de matière à plusieurs doctorats» a déclaré le directeur du JPL, Michael Watkins .

En effet ces précieuses informations vont aider à la compréhension de la formation et de l’évolution de la planète gazeuse, selon les scientifiques.

La sonde a effectué une exploration des plus fructueuses de la planète gazeuse et de ses lunes.

Les scientifiques disposent désormais d'une mine de données à analyser. «Nous en avons pour plusieurs décennies encore. » d'après Linda Spilker, responsable scientifique de la mission « C'est un marathon scientifique de treize années que nous venons de terminer, mais il reste tant de choses à expliquer!»

Aux spécialistes du JPL de dresser le bilan de ces vingt années passées dans l'espace, dont treize en orbite autour de Saturne.

La sonde a fait des découvertes extraordinaires comme des mers de méthane liquide sur Titan, son plus grand satellite naturel, et un vaste océan d’eau salée sous la surface glacée d’Encelade, une petite Lune saturnienne.

Les données recueillies par le spectromètre de Cassini ont également révélé la présence d’hydrogène.

Cet hydrogène signale une activité hydrothermale propice à la vie.

Cette découverte majeure du mois d'avril dernier a ouvert de nouveaux horizons aux scientifiques, comme la recherche la vie extraterrestre.

« Ce monde océanique d’Encelade a vraiment changé notre approche ur la recherche de la vie ailleurs dans notre système solaire et au-delà », a expliqué Linda Spilker.

Les deux lunes que sont Titan et Encelade abritant un vaste océan d'eau liquide et abondant en molécules organiques complexes réunissent tous les ingrédients nécessaires à l'apparition de la vie !

Cassini c'est aussi l'histoire d'une belle coopération entre la NASA, l’Agence spatiale européenne (ESA) et l’Agence spatiale italienne. Ces deux dernières ont construit la petite sonde Huygens que Cassini a transporté jusqu’en décembre 2004 date de son atterrissage sur Titan.

Le 23 août 2017, Elon Musk, le fondateur de Space X et de Tesla, a dévoilé sur Instagram un premier visuel de sa nouvelle combinaison spatiale.

La nouvelle combinaison spatiale d'Elon Musk va ringardiser celle de Thomas Pesquet

Le défi principal était de concevoir un équipement aussi pratique que beau."C'était incroyablement dur d'équilibrer l'esthétique et le fonctionnel".

Le défi a, semble-t-il, été relevé haut la main.

Assurément le design de ce scaphandre de l'espace paraît sur la partie de la combinaison que l'on aperçoit nettement plus esthétique que les standards actuels:

Taille réduite du casque d'une ressemblance ahurissante avec celui d’un des deux membres de Daft Punk, coupe ajusté ... On est pas loin de la combinaison du Valerian de Besson !

Elon Musk assure qu’elle a été testée et approuvée.

Cette tenue fonctionnelle..

Conçue en interne les coûts de production ont été réduit.

Ne permettant pas de se déplacer dans l’espace, elles seront plutôt portées lors du transport en capsule pour servir de sécurité en cas de dépressurisation de la capsule.

Le patron de Space X a conçu la combinaison spatiale que porteront les équipages des vols spatiaux autour de la Lune, programmée pour 2018 comme Elon Musk l'avait espéré en début d'année. Une première étape avant de viser Mars.

Le patron de SpaceX promet d’autres informations sur son programme spatial dans les jours à venir.

L’emploi du temps d’Elon Musk est des plus chargés en ce moment...

Les éclipses de Soleil longtemps mystérieuses pour les hommes ont été attribuées à des causes surnaturelles y voyant l'intervention d'une divinité, d'un démon ou d'un génie malin: pour les Chinois, c’était un dragon dévorait notre étoile, tandis que chez les Viking, c'était des loups la capturaient...Cela a pris du temps pour découvrir que le véritable coupable était la Lune. De nos jours, les scientifiques savent prédire les éclipses avec une extrême précision (moins d'une seconde)

« Il a fallu les observations des astronomes et l'étude du mouvement du Soleil et de celui de son satellite naturel, pour comprendre que c'est la Lune qui à chaque éclipse s'interpose devant le Soleil », souligne Pascal Descamps, astronome à l'Institut de mécanique céleste et de calcul des éphémérides (IMCCE) à Paris.

Alors que la dernière éclipse totale visible depuis la France remonte au 11 août 1999, les Américains, eux, vont vivre le lundi 21 août 2017 la première éclipse de Soleil totale qui traversera le pays d'est en ouest depuis 1918. Un événement si rarissime que l'éclipse risque d'être la plus scrutée de l'histoire de l'humanité.

L'éclipse sera totale :

en effet la Lune cachera intégralement le Soleil, sur un couloir large de 113 km de large qui concernera 14 Etats :

Oregon, Idaho, Wyoming, Montana, Iowa, Kansas, Nebraska, Missouri, Illinois, Kentucky, Tennessee, Georgia, Caroline du Nord et Caroline du Sud.

Certains endroits français comme les Antilles, la Guyane et Saint-Pierre-et-Miquelon vivront également ce phénomène.

En France métropolitaine, l'éclipse sera "en gros invisible, sauf depuis la pointe bretonne", a déclaré Pascal Descamps, astronome à l'Institut de mécanique céleste et de calcul des éphémérides (IMCCE).

Le meilleur endroit pour tenter de l'apercevoir sera Quimper (Finistère) et ses environs, avec un début à 21h41 et le maximum à 22h10.L'éclipse solaire est le résultat de l'alignement des trois astres que sont la Terre , la Lune et le Soleil.

La Lune va en effet se glisser entre la Terre et le Soleil, occultant pendant quelques minutes sa lumière.

Le diamètre du Soleil est 400 fois supérieur à celui de la Lune mais l'étoile est également 400 fois plus éloignée que le satellite naturel de la planète bleue.

Depuis la Terre, cette géométrie donnera donc l'impression que le Soleil et la Lune ont de même taille.

Lorsque les deux seront alignés, la Lune masquera entièrement le Soleil et le ciel deviendra noir quelques minutes seulement en pleine journée. On parle alors d'une éclipse totale. Cette dernière se produit tous les douze à dix-huit mois quelque part dans le monde mais cela ne touche qu'une étroite bande de notre planète, le plus souvent ère inhabitée (océans, pôles, déserts).

Lors d'une éclipse, la Lune cachant le Soleil, on peut observer sa couronne solaire, une zone de très haute température extrêmement dynamique que l'éclat du Soleil cache.

La couronne solaire est cette atmosphère externe de notre étoile s'étendant sur plusieurs millions de kilomètres. Sa température varie entre 1 à 3 millions de degrés alors que la surface du Soleil est à 6000 degrés. Les astronomes étudient comment l'atmosphère terrestre et le sol de notre planète réagissent à la baisse de température soudaine provoquée par une éclipse dans la zone concernée.

Le 2 juillet 2019, le Pacifique et l'Amérique du Sud (Chili et Argentine) seront concernés. Idem le 14 décembre 2020 (Pacifique, sud du Chili, Patagonie puis Atlantique). Le 4 décembre 2021, ce sera au tour de l'Antarctique. Le 20 avril 2023,touchera essentiellement l'Indonésie et l'Australie ,les États-Unis vivront une autre éclipse totale en 2024tandis que la France devra attendre le 3 septembre 2081 !

The Night of the Stars.
This year it is this weekend that you may have the chance to make a wish to see a shooting star.







To contemplate the heavenly vault you have to, a telescope if you can or go to an observatory.





Inquire: sites are open to observe these stars but you can see them with the naked eye.

A site has been opened to understand stars like Great Bear, Jupiter, Saturn Rings, etc...











Tap on your Pad '' Nights of the Stars '' and go on August 13th for the rain of the shooting stars.
I leave you I go to the Nice Observatory to watch them.

Le vice-président américain Mike Pence a annoncé jeudi l'avènement d'une «nouvelle ère» dans l'exploration spatiale. Il prévoit l'envoi par les États-Unis d'une mission habitée sur Mars et le retour d'astronautes sur la Lune.

Récemment nommé à la tête du Conseil spatial national, un organe consultatif, Mike Pence vient de visiter le Centre spatial Kennedy près de Cap Canaveral en Floride et a été impressionné par les capsules spatiales en cours de construction par le secteur privé pour le compte de la NASA.

«Notre pays retournera sur la Lune et nous mettrons des bottes américaines sur la surface de Mars», aaffirmé Mike Pence devant environ 800 employés de la NASA.


Était également présent Buzz Aldrin, le deuxième homme à avoir marché sur la Lune après Neil Armstron

La NASA travaille sur un projet baptisé «Deep Space Gateway» pour envoyer des astronautes en orbite lunaire avec de nouvelles fusées développées par l'agence spatiale américaine.

L'envoi d'astronautes sur Mars d'ici 2030 figurait déjà parmi les priorités affichées des programmes spatiaux des présidents Barack Obama et George W. Bush.

Voyages spatiaux moins coûteux

Depuis l'arrêt des navettes spatiales américaines en 2011, les astronautes américains dépendent des vaisseaux russes Soyouz s'ils veulent se rendre dans la Station spatiale internationale (ISS.).

Le siège est à plus de 80 millions de dollars !.



Les entreprises américaines SpaceX et Boeing travaillent toutes deux à des capsules pour le transport des astronautes en orbite terrestre dès 2018.

Mike Pence devant une capsule Dragon de SpaceX et un prototype du futur vaisseau Starliner de Boeing, a souligné que le gouvernement américain  favoriserait la coopération avec le secteur privé pour rendre les voyages spatiaux moins chers, plus sûrs et plus accessibles.

Le président Donald Trump a proposé un budget de 19,1 milliards de dollars pour la NASA, une baisse de 0,8% par rapport à 2017.

Il a demandé à l'agence spatiale d'abandonner son projet de capturer un astéroïde et a mis fin aux financements demissions destinées à étudier le changement climatique et les sciences de la Terre.

Les rumeurs vont bon train sur Internet et se répandent tels des virus malfaisants. A tel point que la Nasa a préféré  démentir  immédiatement  la rumeur  partie d'un témoignage lors d'une émission de télévi « enfants »sion américaine..

Le présentateur Alex Jones jeudi 29 juin qui affectionne tout particulièrement les théories du complot, a invité Robert David Steele à s’exprimer dans son émission The Alex Jones Show, diffusée sur pas moins de 118 stations de radio dans tous les Etats-Unis. .

Voilà notre homme se présentant comme un ex-agent secret qui se met a affirmer que des enfants étaient kidnappés puis envoyés sur Mars via un voyage de vingt ans.

L’homme est là pour parler de Mars certes, et il a des "révélations" à faire certes mais quelles révélations !

Une fois arrivés, ces n’avaient d’autre choix que de devenir des esclaves dans les colonies martiennes

.Et ce n’est pas tout. Robert David Steele ajoute :

« Ils les terrorisent pour enrichir leur sang en adrénaline, et les tuent. Ça inclut aussi de les tuer, comme ça, ils peuvent récupérer la moelle récoltée. »

« Nous croyons réellement qu'il y a sur Mars une colonie habitée par des enfants esclaves, raconte-t-il, d'un ton grave. Ils y arrivent après un voyage de vingt ans dans l'espace. Et une fois arrivé sur place, ils n'ont plus d'autre choix que de devenir des esclaves ».

Mais ce n’est pas tout. D’après lui, la Nasa kidnapperait ces enfants, dans le but de « remplir leur sang d'adrénaline », puis les assassinerait « pour récupérer leur os, leur moelle" »,?! Des vampires quoi !?

S agit-il de l'hormone de croissance originelle ?

A la question du présentateur, sur le bien-fondé de cette révélation :

« Absolument, c'est un truc antivieillissement », renchérit alors le soi-disant ex agent-secret.

La folle rumeur se répand comme une traînée de poudre sur la toile.

La Nasa a immédiatement démenti dans le Daily Beast, par la voix de son porte-parole Guy Webster. « Il n’y a pas d’humain sur Mars. Il y a des robots actifs sur Mars. Une rumeur était en train de se propager la semaine dernière qu’il n’y en avait pas. Il y en a. Mais il n’y a pas d’humain. »

Mieux vaut en rire qu'en pleurer !!

Certains ont préféré le prendre avec humour.

« Si la NASA a kidnappé des gosses pour les envoyer sur Mars, il est mathématiquement impossible qu’il y ait des "colonies d’enfants" là-bas. Selon votre copain, ils ont voyagé 20 ans pour arriver à destination. DONC CE SONT DES COLONIES D’ADULTES. » dans le Parisien

A un autre internaute américain de le prendre au second degré Sur Reddit, :

"Un démenti... C'est exactement ce que ferait quelqu'un qui détient une colonie d'enfants esclaves sur Mars".

Gardons d'ailleurs en mémoire qu'Alex Jones se fait souvent l'avocat  de ce genre de rumeur .

Ainsi en 2016, lors de la campagne présidentielle, le producteur avait répandu la folle rumeur selon laquelle des proches d’Hillary Clinton géraient un réseau pédophile dans la cave d’une pizzeria à Washington !

Ce qui aurait pu provoquer une tragédie humaine !! Sûr de cette information, un homme s’était précipité dans ce fameux restaurant pour ouvrir le feu mais heureusement sans faire de victime...

Il revient avec la "conscience que la planète est vraiment un joyau". "De voir la planète, de voir sa fragilité, de prendre du recul, cela permet d'apprécier cette fragilité-là", dit-il. "On n'a pas conscience à quel point l'atmosphère c'est mince (...), à quel point on est capable d'abîmer la planète, à quel point il faut la protéger."

Thomas Pesquet revient sur Terre après une mission de six mois dans l'espace vendredi, au terme

d'une mission bien remplie!

Comme prévu, à un minute près, l'atterrissage a eu lieu à 16h10, heure française, dans les plaines désertes des steppes kazakhes, un peu plus de trois heures après que leur vaisseau s'est détaché de l'ISS à 12h49. Chacun équipé d'un scaphandre, les astronautes ont pris place dans la capsule Soyouz, qui s'est désamarrée de la Station spatiale internationale à 12h50 (heure française). Après un long parachutage, la capsule s'est posée à 16h10 sur le sol du Kazakhstan.

Les premières images du Français l'ont montré souriant et visiblement en bonne santé. Thomas Pesquet allait rejoindre Cologne.

La mission Proxima du 10e astronaute français de l'histoire prend fin, après six mois et demi passés dans l'espace confiné de l'ISS : à peine 400 m3 habitables c-à-d un appartement de 130 m2 avec trois mètres de plafond. À partager avec quatre à cinq colocataires. Pendant 196 jours !

Avant de s'envoler pour la Station spatiale internationale (ISS) en novembre dernier, Thomas Pesquet faisait de son retour en capsule Soyouz, l'un des moments les plus attendus de sa mission.

Avec le cosmonaute russe Oleg Novistky, qui a piloté la boîte de conserve de 2,2 m de diamètre et de 2,1 m de haut, le Français a effectuer une rentrée dans l'atmosphère à la vitesse vertigineuse de 28.000 km/h !!!

«C'est l'accomplissement d'un énorme travail collectif»

Outre les effets personnels, ne repartent en Soyouz que les données d'expériences scientifiques (échantillons ou disques durs).

L'ex-pilote de ligne d'Air France a souligné que ce qui lui avait le plus manqué bien sûr ses proches mais aussi le sentiment de liberté: «Aller dehors, faire un tour de vélo, aller à la montagne, la mer, des sensations bêtes: le vent, la pluie, des odeurs différentes, un peu de perspective…» Il ne regrettera ni la nourriture, «pas terrible», ni les «toilettes de camping» !

Mais avant tout chose des souvenirs extrêmement positifs. Les sensations du décollage depuis Baïkonour, les seize levers de soleil quotidiens à bord de l'ISS, la vie en apesanteur, et les deux sorties en scaphandre réalisées en janvier et en mars. Ces dernières étaient destinées pour des opérations de maintenance pendant lesquelles il tenait la Station d'une main et voyait la Terre défiler juste sous ses pieds 400 km plus bas. Il s'est montré très professionnel.

Sur le plan scientifique, l'installation de la machine Mares qui mesurait l'activité musculaire des astronautes pendant des séances d'exercice l'a marqué. «C'est l'accomplissement d'un énorme travail collectif»

Le Normand a participé à une centaine d'expériences scientifiques, dont une soixantaine menées pour le compte des agences spatiales européenne (ESA) et française (Cnes). Les passagers de l'ISS sont de véritables cobayes et sont soumis à de très nombreux tests. Il s'agit d'avoir une meilleure compréhension de l'apesanteur sur le corps humain. L'état de quasi-apesanteur dans lequel il était baigné lui a permis d'effectuer des expériences inédites, à commencer par les effets de cette microgravité sur son propre corps .

En parallèle, ils mènent aussi des expériences de physique fondamentale, sur l'étude du comportement des fluides et des matériaux en apesanteur, ou de biologie, comme la culture de légumes.

Toutes nos felicitations à ce brillant scientifique français dont la France est fière.

On connaît l'entraînement sportif quotidien de nos astronautes à bord de l'ISS.

L'astronaute français Thomas Pesquet, en mission dans l'espace pour 6 mois, demeure avant tout un bon citoyen ! Le voilà qui nous convie,  nous Terriens, d' aller voter en ce dimanche brumeux

.En orbite à 400 km au-dessus de la Terre il n’en oublie pas l’élection présidentielle : Espérons qu'il avait pour divertissement mieux à se mettre sous la dent que les insipides débats politiques servis à nous pauvres Terriens réduits à voter entre ? J'aurais préféré vivre à ces moments là entre le flot interrompu d'images de l'espace céleste depuis la Station spatiale internationale ! et faire un grand retour sur Terre en juin prochain .Et quitte à faire après les législatives... Pour un quotidien bien différent d'une vie sur la Terre.

Leur mission à tous devra leur réussite également de l'entente de l’équipe notamment du caractère des habitants de l'ISS. Et la personnalité du candidat a fait partie des critères de sélection. Que de qualités rares requises en un même individu.

Vivre pendant six mois dans un espace restreint, en apesanteur, demande de grandes capacités d' adaptation à son environnement : dormir dans un sac de couchage accroché au mur, se laver  avec des lingettes humides, s'exercer et faire de la muscu plus de deux heures par jour…

L'équipe de la Station spatiale internationale s'est organisée en créant un rythme régulier qui frôle la normalité..« On a des lumières qu'on allume à 6 heures quand on se lève, et on les éteint à 23 heures, et puis certaines changent d'intensité », raconte Thomas Pesquet à un journaliste. « Heureusement, sinon ce serait éreintant. » ; Et bien sûr les tempéraments des uns et des autres au quotidien est pour beaucoup dans le bon déroulement de la mission et dans les performances de l'équipe : DEHORS LES GRINCHEUX, ICI PLACE AUX ESPRITS CONCILIANTS !

Un astéroïde géant, estimé actuellement à 852 mètres de large et baptisé 2014-JO25 passera à 1,8 million de kilomètres de notre Terre : Soit, un peu plus de quatre fois la distance de la Terre à la Lune donc moins de 1,8 million de km. Et ce dans la nuit de ce mercredi 19 avril 2017. Représente-t-il un danger immédiat pour la Terre ? Non selon la Nasa. Bien que classé par la Nasa dans la catégorie «potentiellement dangereux», cet objet céleste ne menace pas de frapper la Terre.

L'Agence spatiale américaine assure qu'il "volera en toute sécurité". L'astéroïde 2014-JO25 ne fera que "frôler" la Terre. Il sera 23h23, heure française, lorsque l'astéroïde passera au plus près de nous...

Alors à vos télescopes !

A l'oeil nu, impossible d'observer le phénomène, en revanche un télescope de 20 cm suffira pour suivre son périple pendant deux nuits. Pour une bonne observation l'environnement doit être le plus sombre possible mais ce qui s’avérera surtout difficile , c'est de suivre l'astéroïde, l'objet s'approchant à une vitesse impressionnante de 120000 km/h (ou 33 km/s) de la Terre !!! La dernière fois que 2014-JO25 nous a rendu visite cela remonte à 400 ans et on ne le reverra pas avant 2.600 ans.

Les astronomes attendent avec impatience le passage de ce gigantesque caillou car son observation permettra d'établir plus précisément sa taille.

Avoir des données précises de la taille et de la forme est très important, puisqu'on n'en déduit la densité de l'objet... C'est important de savoir si c'est un rocher friable ou objet ferreux, qui traverse notre ciel en cas d'une éventuelle collision avec la terre.

La rencontre du 19 avril offre aux scientifiques une belle opportunité d'étudier de bien plus s près cet astéroïde. Des observations radar sont prévues au Goldstone Solar System Radar de la NASA en Californie et à l'Observatoire Arecibo de la National Science Foundation à Porto Rico. La précisions des images pourraient révéler des détails en surface jusqu’à quelques mètres.

Il faudra attendre le 7 août 2027 pour voir un aussi gros objet, 199-AN10 et ses 700 m s'approcher tout près de la Terre : Apophis, un beau bébé de 310 m qui flirtera avec la planète bleue, à 38 000 km, un dixième de la distance Terre-Lune.

Par contre le cas du dénommé 410777 (2009-FD) est préoccupant. Ce corps d'au moins 160 mètres a une chance sur 710 d'impacter la Terre le 29 mars 2185 détruisant alors une région de la taille d'un petit Etat ou provoquant des tsunamis. L'astroide 29075 (1950-DA) s'avère plus inquiétant dans la mesure où ce titan de 1,3 km pourrait nous frapper de plein fouet . Mais la probabilité que ce désastre advienne est de 1/8300.

Et la menace n'est pas pour demain, le contact éventuel étant prévu en 2880 !

Mais au sein de l'Agence spatiale américaine, une équipe surveille les géocroiseurs, c'est-à-dire ces objets voués à croiser un jour l'orbite de la Terre. Le Center for Near Earth objects studies (CNeoS) tient même une base de données des impacts possibles. Si elle précise que la «probabilité» de ces événements est «très faible», la Nasa considère qu'au vu des connaissances disponibles, le risque existe. Depuis une dizaine d'années, la Nasa et l'Agence spatiale européenne (Esa) ont lancé plusieurs programmes de détection des géocroiseurs. C'est ainsi que dans le cadre d'une mission conjointe avec l'Esa, la Nasa lancera en 2020 la sonde Dart droit sur l'astéroïde Didymoon pour voir s'il est possible de dévier un astéroïde sans utiliser la force nucléaire. Gageons qu'avant 2880 l'humanité aura trouver les moyens d'épargner la Terre.

Impressionnante la première sortie en scaphandre de l'astronaute français le 13 janvier si bien que la Nasa l'a retenu pour faire deux excursions de plus à l'extérieur de la station spatiale internationale.

Impressionnante la performance de Thomas Pesquet avec son coéquipier américain Shane Kimbrough :

l'équipe a parfaitement effectuer les tâches et réussi cette prestation avec une heure et demie d'avance sur le planning prévu !!!

Même si l'on comptabilise les opérations facultatives, la durée de leur intervention autour de l’ISS aura été plus courte que le timing imaginé par la Nasa : seulement 5h58 au lieu des 6h30 initialement prévues pour réaliser les tâches.

Certes, on pourra toujours objecter que Thomas Pesquet était assisté d’un vétéran des sorties extravéhiculaires (Kimbrough en compte quatre à son actif), mais l'astronaute français s 'est montré superperformant au point de taper dans l'oeil de la NASA qui lui confie deux autres sorties.

L’Agence spatiale européenne (ESA) a bien confirmé que l’astronaute Thomas Pesquet effectuera deux nouvelles excursions à l’extérieur de la Station spatiale internationale.

Fin mars et en avril pour ses deux prochaines sorties extravéhiculaires, mais les dates ne sont pas encore arrêtées en raison de nouvelles pièces attendues du cargo automatique Cygnus

Les deux sorties détaillées par l’ESA

La première sortie de Thomas Pesquet se fera en compagnie du même Shane Kimbrough .

Les deux hommes auront pour

«  mission d’installer un nouvel ordinateur, de réaliser de la maintenance sur le système électrique et de déconnecter un adaptateur du système d’amarrage avant qu’il ne soit déplacé »,

précise le communiqué de l’ESA.


Cette mission, d’une durée de plusieurs heures, les conduira à travailler séparément une grande partie de la sortie Pour sa deuxième sortie, accompagné de Peggy Whitson, le spationaute français travaillera

« sur le remplacement d’une alimentation électrique destinée aux expériences scientifiques, mais aussi la grande expérience de recherche d’antimatière, AMS-02 », détaille l’ESA dans son communiqué.


Pour l’ESA, la décision d’impliquer Thomas Pesquet dans deux autres missions

« témoigne des bonnes performances des astronautes de l’ESA ces dernires années ainsi que de la qualité de l’entraînement qu’ils suivent dans le Centre des astronautes européens ».

Avec ses trois sorties il égalera ainsi le record établi par son collègue français Philippe Perrin qui a lui aussi effectué trois sorties dans l'espace lors d'une seule mission.

Un nouveau record pour la France !

Thomas Pesquet rentrera sur Terre au cours du mois de mai 2017, après six mois dans l’espace pour sa mission Proxima.

En avril 2015, la perte d'un Progress avait déjà provoqué une profonde crise dans l'industrie spatiale russe. La Russie ayant dû alors suspendre tous ses vols spatiaux pendant près de trois mois.

Le vaisseau cargo avait également perdu contact avec la Terre avant de se consumer dans l'atmosphère. les Russes avaient attribué ce revers à une panne sur la fusée Soyouz. obligé un Un groupe d'astronautes avaient dû prolonger d'un mois leur séjour à bord de la station de recherche spatiale.

Le vaisseau-cargo non habité qui devait ravitailler la Station spatiale internationale (ISS) lequel le s'est consumé dans l'atmosphère peu après son décollage de Baïkonour au Kazakhstan( annonce de l'agence spatiale russe).

Perdu à quelque 190 km au-dessus de la région isolée et montagneuse de Touva, « la plupart des fragments ont brûlé dans les couches denses de l'atmosphère », a précisé Roskosmos.

Cette perte "n'affectera pas le fonctionnement normal des équipements de l'ISS et la survie de l'équipage de la station"car les réserves à bord de l'ISS étaient à "un bon niveau"

Progress MS-04 transportait un chargement d'environ 2,4 tonnes, dont de l'eau, des carburants et du gaz comprimé, ainsi que des produits alimentaires, des vêtements et des médicaments pour l'équipage de l'ISS composé actuellement du Français Thomas Pesquet, des Américains Peggy Whitson et Shane Kimbroughet, ainsi que des Russes Oleg Novitski, Sergueï Ryjikov et Andreï Borissenko.

Son arrimage à l'ISS était initialement prévu pour 16H43 GMT samedi et devait se faire en régime automatique, selon Roskosmos.

La Nasa a précisé que la première et deuxième étape se sont bien déroulées, mais qu'un problème a été enregistré lors de la troisième étape de la séparation entre le vaisseau Progress MS-04, qui devait se retrouver en orbite, et le lanceur Soyouz.

Une enquête est en cours.

Thomas Pesquet se trouve à bord de la Station spatiale internationale depuis le 20 novembre où de nombreuses expériences seront menées sur les astronautes. Le Français en est à sa deuxième sur les 21 des 55 expériences que va mener Thomas Pesquet pour l'Esa.

Les performances en micropesanteur de surfaces et revêtements innovants qui empêchent les bactéries de proliférer a été la première expérience de notre Français.

Cette étude- menée à l'aide du module Mattis- est rendue possible par le confinement de la Station spatiale.

En effet le recyclage permanent de l'eau et de l'air et le stockage à bord des déchets produits favorisent la prolifération de bactéries.

Avec une telle expérience le Cnes entend réduire les risques de contamination en s'intéressant aux propriétés antibactériennes de matériaux dans l'espace.

Bien entendu les retours serviront aussi aux hommes évoluant sur Terre:ainsi les chercheurs ont à cœur d’éliminer la concentration de bactéries sur les rampe d’escaliers, de métro, des poignées de portes... La deuxième expérience de Thomas Pesquet est celle de l'atrophie musculaire en apesanteur.

Elle sera renouvelée deux fois avec de nouvelles mesures effectuées dans dix jours puis 30 à 45 jours avant son retour sur terre.

En six mois un astronaute perd entre 20% ET 30% de sa masse musculaire. Une application directe : aider à la réadaptation des personnes longtemps alitées ou permettre à l'homme d'arriver en forme sur Mars.

Le module MARES ressemble à une énorme chaise équipée de capteurs. L' instrument scientifique MARES -une sorte d' énorme chaise équipée de capteurs- mesure la force exercée par des groupes musculaires isolés autour de toutes les articulations du corps cinq heures d'affilée !

La comète ISON survivre à son plongeon dans l'atmosphère du soleil ou entend-elle périr , comme Icare , pour s'aventurer trop près ? Les astronomes disent que les rapports de sa mort imminente sont grandement exagérées .

ISON , connu officiellement comme C/2012 S1, est une comète soleil pâturage qui est mis à venir au sein de 730,000 miles de la surface de notre étoile à la maison en Novembre et puis dévalent par la Terre au début de Décembre . On croit provenir de la nuage d'Oort , un cluster hypothèse d'objets glacés à proximité des franges du système solaire , 50.000 fois plus loin que le soleil est de la Terre.

Compte tenu de la trajectoire de la comète, c'est peut-être notre seule visite de ISON , comme la gravité du soleil devrait fronde il vers l'arrière sur le système solaire interne - qui est, à moins que le soleil frites et déchire le distingue d'abord.

Cette inquiétude a frappé certains observateurs de la comète qui attendent sa terre très attendu fly-by en Décembre. Le rayonnement du soleil peut faire bouillir l'écart de son contenu glacées , et son attraction gravitationnelle intense pourrait déchirer la comète en lambeaux.

Mais les scientifiques disent qu'il n'y a aucune raison de compter sur ISON pour l'instant. Une étude publiée dans la revue Astrophysical Journal Letters a examiné les dossiers historiques de cométaires rencontres rapprochées avec le soleil et a constaté que ISON - alors que nous savons très peu de choses encore - est probablement trop dense pour être totalement déchiqueté par le soleil.

Au moins une partie de la comète devrait survivre à la fois la perturbation de marée de la gravité et de la sublimation du soleil ( la glace étant évaporée directement de l'état solide à l'état gazeux ) .

«Que ce soit ou non interruption se produit , le plus important reste doit être assez grand pour survivre perte de masse ultérieure en raison de sublimation pour que ISON à rester une comète viable bien après périhélie », écrivent les auteurs .

Les scientifiques de l' Comet campagne d'observations ISON NASA ont exprimé la même idée.

" Est-ce que cela ressemble à une comète fait long feu ? "

Karl Battams , astrophysicien au Laboratoire de recherche navale à Washington , a écrit dans un billet de blog , en montrant une photo de la longue queue , la comète verte éclatante pris des jours avant .

Les astronomes ne sont certainement pas en démissionnant - 18 satellites sont mis à l'image de la comète.
