ExoMars (Exobiology on Mars) is an astrobiology project to investigate the past habitability environment of Mars and to demonstrate new technologies paving the way for a future Mars sample return mission in the 2020s. ExoMars is a joint mission of European Space Agency (ESA) and Russian Federal Space Agency (Roscosmos). The mission will search for biosignatures of Martian life, past or present, employing several spacecraft elements to be sent to Mars on two launches. The ExoMars Trace Gas Orbiter (TGO) and a test stationary lander called Schiaparelli were launched on 14 March 2016. The TGO will deliver Schiaparelli lander in 19 October 2016, and then proceed to map the sources of methane on Mars and other gases. The TGO features four instruments and will also act as a communications relay satellite.
