China launched 2 satellites.

On November 9, 2011 at 03:21 UTC the "Chang Zheng-4B” (Long March 4B) rocket-carrier was launched from the Taiyuan Satellite Launch Center in Taiyuan, capital of north China's Shanxi Province. The rocket orbited the "Yaogan XII” remote-sensing satellite and the "Tianxun I” satellite.

The "Yaogan XII” satellite will be used to conduct scientific experiments, carry out surveys on land resources, estimate crop yield and help with natural disaster-reduction and prevention.

The "Tianxun I” satellite will be used to carry out technological verification tests.

Russian “Phobos-Grunt” probe fails to set course to Mars.

The "Phobos-Grunt” robotic spacecraft failed to reach a flying orbit to Mars after separation from the launch vehicle. The spacecraft was supposed to use its own booster to reach the designated flying trajectory, but failed to do so.

The technicians have three days to start the on-board engine and put the probe on the designated trajectory before the batteries run out. The potential loss of the Phobos-Grunt probe could deliver another serious blow to the country’s space exploration program as Russia has previously failed several attempts to send unmanned spacecraft to Mars.

Russia launched a robotic spacecraft to Phobos, Mars’s natural satellite.

On November 8, 2011 at 20:16 UTC (November 9 at 00:16 Moscow time) the two-stage "Zenit-2SB” rocket-carrier was launched from Baykonur Cosmodrome. The launch was performed by Russian and Ukrainian specialists. The rocket orbited the "Phobos-Grunt” probe.

The ambitious "Phobos-Grunt” mission is aimed at bringing back soil samples from Phobos in 2014 to pave the way for the exploration of the Red Planet. The $163-million spacecraft is carrying an array of 20 instruments designed to gather and transmit data from the vicinity of Mars and from the surface of Phobos.

The "Phobos-Grunt” is also carrying several other payloads, including a Chinese sub-probe Yinghuo 1 that will separate from Phobos-Grunt and go into orbit around the Red Planet, as well as a capsule with microbes to study how life forms survive long fli ... Read more »
