Phobos-Grunt is a mission to Phobos, one of the two small satellites of Mars; it was developed by the Russian agency Roskosmos, with the participation of other countries to the science payload. Launch occured in Baikonur, on November 8, 2011, for an arrival end-2012, and a landing on Phobos mid-2013; the payload consisted in Phobos-Grunt and YingHuo-1, a Chinese satellite, intended to study Mars and Phobos. One of the goals of Phobos-Grunt was to proceed to in situ soil analyses, to help understand the composition of Phobos (structure, mineralogy, organic matter), hence its origin. About 200 g of soil samples should have been sent from Phobos to Earth, for a; landing in 2014. Unfortunately, due to some concerns in the cruise stage, the probe was unable to leave its elliptical orbit around the Earth, and to begin its cruise to Mars and Phobos. After orbiting for 2 months, it desintegrated while entering Earth dense layers of the atmosphere, and the...
