Phobos-Grunt: Destination Mars in 2011, Feb. 2010, http://www.cnes.fr/web/CNES-en/8308-gp-phobos-grunt-destination-mars-in-2011.php
Russia's Phobos-Grunt mission would have study Mar's moon, Phobos, as well as return soil samples to Earth in order to determine the origin and evolution of this moon. In addition to its own mission, Phobos-Grunt also carried China's first interplanetary mission to Mars called Yinghuo-1. Phobos-Grunt was be Russia's first interplanetary mission since the unsuccessful Mars 96 mission.
After an 11-month voyage to Mars, Phobos-Grunt was to begin probing Mars' magnetosphere and atmosphere. At this time, Phobos-Grunt would have released China's Yinghuo-1 orbiter into a near-equatorial, elliptical orbit.
Afterwards, Phobos-Grunt was to release a lander on Phobos to collect 200 grams of rock and dust, as well as make other experiments to study Phobos and its environment. The samples would then have been launched back to Earth in a sample return capsule for study.
The Phobos-Grunt spacecraft is in Earth orbit and did not perform its scheduled burn to begin its trajectory to Mars and both spacecraft were stranded in Earth orbit after communications failed.
