Fobos-Grunt (also spelled Phobos-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.
