Three days before arriving at Mars on 19 October 2016, the ExoMars Trace Gas Orbiter (TGO) will release its entry, descent and landing demonstrator, Schiaparelli, towards the Red Planet. ExoMars is several missions in one. Its orbiter is a science and relay mission.
The TGO will search for evidence of gases, such as methane, that may be associated with geological or biological processes.
The Schiaparelli lander is a technology demonstrator to test key technologies for future missions to Mars.
