Philae may not have energy to send results to Earth, says ESA

Europe's robot lab Philae may not have enough power to send to Earth the results of today's drill into the surface of its host comet, mission scientists have said.

Rosetta space probe makes historic rendezvous with comet

European scientists announced the historic rendezvous on Wednesday between a comet and the Rosetta spacecraft after a 10-year, six billion-kilometre (3.7-billion-mile) chase through the solar system.

The scout Rosetta has now become the first envoy to orbit one of these wanderers of the solar system in deep space, the European Space Agency (ESA) said.

Scientists and spectators at ESA’s mission control in Darmstadt, Germany, cheered after the spacecraft successfully completed its final thrust to swing alongside comet 67P/Churyumov-Gerasimenko.

Angara rocket test-launched from Plesetsk space center gets to designated spot

Strictly in line with the cyclogram (schedule) of the flight, 21 minutes after the launch, the mass-dimensional model of the payload got to the designated spot on Kura testing range...

Russia’s Aerospace Defense Troops have done the first test-launching of a news Russian carrier rocket Angars-1.2PP, a spokesman for the Plesetsk Space Center in northern Russia told ITAR-TASS.
The launch was carried out as scheduled. The preparations and effectuation were supervised by the Commander of Aerospace Troops, Lieutenant-General Alexander Golovko.

Russia postpones Friday's planned launch of Angara space rocket (VIDEO RIANEWS)

The test launch of an Angara space rocket automatically aborted due to “technical issues,” Russian officials said. While the second attempt is scheduled for Saturday, President Putin has ordered the reasons for the launch failure be detailed in one hour.

The launch of the Angara was aborted just few minutes before the start due to “technical issues,” sources in the Russian space agency Roscosmos said. The mission was aborted automatically.

Pentagon plans multi-billion dollar project to combat space junk

Later this month the US Pentagon plans to award a massive contract to one of the two most influential American contractors for a project that, if all goes according to plan, will be able to identify space debris before it becomes a threat to the Earth.
Lockheed Martin Corp. and Raytheon Co. are competing for the $6 billion contract to design and construct Space Fence, a radar system that will eventually be able to track large bodies of space matter. The plan is being put into place so that the government can not only better predict the bodies that may come into contact with Earth (such as the asteroid that exploded over Chelyabinsk, Russia, for instance) but also to better protect satellites that could be destroyed while in orbit.

Russia, US Plan to Jointly Fight Space Threats

MOSCOW, January 27 (RIA Novosti) – Russian and US experts are planning to join efforts in protecting our planet against thousands of potentially hazardous near-Earth space bodies, Russia’s emergencies minister said.

“The collision with the Chelyabinsk meteorite last year showed that space threats could be real and as destructive as huge fires or natural disasters on Earth,” Vladimir Puchkov said in an interview with Rossiiskaya Gazeta to be published on Tuesday.
The minister said a joint working group would be set up in the near future to develop solutions to counter space threats.

Rosetta spacecraft to be woken after nearly three years, ESA awaits signs of life

The European Space Agency (ESA) is awaiting signs of life from its comet-chasing spacecraft Rosetta. The probe - now in the vicinity of Jupiter's orbit - has been in hibernation for nearly three years. 

An internal "alarm clock" aboard the Rosetta spacecraft was scheduled to go off at 1000 UTC on Monday, waking it up from nearly three years of slumber. But given the six hours Rosetta would need to power up its system, plus the time needed for its signal to traverse the 807 million kilometers (501 million miles) to Earth, the European Space Agency (ESA) said it wasn't expecting to hear anything until the early evening.

Japan's Launching A Giant Net Into Orbit To Scoop Up Space Junk (video fr)

Something must be done to deal with the estimated 100 million bits of man-made space junk circling the planet, and Japan is taking the lead. But can we do? Shoot it with a laser? Invent Wall-E-like robots to collect it? Nah… let’s just blast a big net into space.


Next month, Japan Aerospace Exploration Agency (Jaxa) will do just that. Having teamed up with a company that manufactures fishing equipment, Jaxa developed a wire net nearly 300 metres long but just a foot wide that will be launched into orbit. Once it’s unravelled, the net will generate a magnetic field that will theoretically attract nearby space debris.

Russian Scientist Proposes Satan Missiles to Fight Asteroid Threats

YEKATERINBURG, June 23 (RIA Novosti) – Russia can use Soviet-era SS-18 Satan heavy intercontinental ballistic missiles to destroy celestial bodies posing a threat to Earth, a Russian scientist said on Sunday, four months after a powerful meteor struck Russia’s Urals region.

“Carrier rockets created on the basis of intercontinental ballistic missiles like Voyevoda [the Soviet name of Satan missiles], which use standard liquid fuel based on hydrazine, are well-suited for fighting suddenly discovered small [space] objects,” said Sabit Saitgarayev, a senior researcher at the State Rocket Design Center in the city of Miass in the Chelyabinsk Region.
“They [missiles] can stay in the condition of their readiness for launch for ten and more years, after some reequipping,” the scientist said.

Comment faire le ménage dans l'espace ?


-
Depuis le début de la conquête spatiale dans les années 60, le nombre de débris présents dans l'espace s'est accumulé de manière quasi-exponentielle.
Aujourd'hui une couverture de poubelle high-tech entoure la terre.
Environ deux tiers de ces objets viennent de l'éclatement d'autres débris spatiaux : que ce soient des explosions ou des collisions. Comme celle de 2009 entre les satellites Iridium et Cosmos à près de 800 kilomètres au-dessus de la Sibérie.
La taille des débris varie de quelques millimètres à la taille d'un bus, n'importe lequel d'entre eux peut abimer un vaisseau estime le chef du bureau des débris spatiaux de l'agence spatiale européenne.
