Fobos-Grunt
Fobos-Grunt[2] (also spelled Phobos-Grunt, also called Phobos Sample Return Mission[3]) was an unmanned Russian spacecraft. It was an attempted sample return mission to Phobos, a moon of the planet Mars.[3][4][5] Scientists intended Phobos-Grunt to orbit and study Mars. It was meant to look at Mars' atmosphere and dust storms, plasma and radiation. Then, Phobos-Grunt should have landed on Phobos and returned a 200 g[4][5] soil sample to Earth.[3][4][5][6]

The spacecraft was the first Russian interplanetary mission since Mars 96.[5] It was launched on 8 November 2011 (UTC), aboard a Zenit rocket, at Baikonur Cosmodrome.[3] It was sent with the Chinese spacecraft Yinghuo-1[3][5] and with the Living Interplanetary Flight Experiment.[3]
The name Phobos-Grunt (Russian: Фобос-Грунт) is Russian for Phobos-Soil.[5]
