The main objectives of the European Space Agency's ExoMars Trace Gas Orbiter (TGO) mission are to search for evidence of methane and other trace atmospheric gases that could be signatures of active biological or geological processes on Mars and to serve a communications relay for future missions, including NASA missions.
The mission also carried Schiaparelli, an entry, descent and landing demonstrator module.
Exomars Trace Gas Orbiter successfully entered Mars orbit on Oct. 19, 2016. Schiaparelli was lost on decent.
