Phobos-Grunt (also spelled Fobos-Grunt, also called Phobos Sample Return Mission) was an unmanned Russian spacecraft. It was an attempted sample return mission to Phobos, a moon of the planet Mars. 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 soil sample to Earth.
The spacecraft was the first Russian interplanetary mission since Mars 96. It was launched on 8 November 2011 (UTC), aboard a Zenit rocket, at Baikonur Cosmodrome. It was sent with the Chinese spacecraft Yinghuo-1 and with the Living Interplanetary Flight Experiment.
The name Phobos-Grunt (Russian: Фобос-Грунт) is Russian for Phobos-Soil.
