Fobos-Grunt - Orbiter Space Flight Simulator 2010

Fobos-Grunt or Phobos-Grunt (Russian: Фобос-Грунт, literally "Phobos-Ground") was an attempted Russian sample return mission to Phobos, one of the moons of Mars. Fobos-Grunt also carried the Chinese Mars orbiter Yinghuo-1 and the tiny Living Interplanetary Flight Experiment funded by the Planetary Society. It was launched on 8 November 2011, 20:16 UTC from the Baikonur Cosmodrome, but subsequent rocket burns intended to set the craft on a course for Mars failed, leaving it stranded in low Earth orbit. Efforts to reactivate the craft were unsuccessful, and it fell back to Earth in an uncontrolled re-entry on 15 January 2012, over the Pacific Ocean west of Chile. The return vehicle was to have returned to Earth in August 2014, carrying up to 200 g of soil from Phobos. Before reentry, the spacecraft still carried about 7.51 metric tonnes of highly toxic hydrazine and nitrogen tetroxide on board. This was mostly fuel for the spacecraft's upper stage. These compounds, with melting points of 2 °C and −11.2 °C, are normally kept in liquid form and were expected to burn out during re-entry.
