ExoMars Trace Gas Orbiter

The ExoMars Trace Gas Orbiter (TGO or ExoMars Orbiter) is a collaborative project between the European Space Agency (ESA) and Roscosmos. A key goal is to gain a better understanding of methane (CH 4) and other trace gases present in the Martian atmosphere that could be evidence for possible biological activity.

Schiaparelli EDM was a failed Entry, Descent and Landing Demonstrator Module (EDM) of the ExoMars programme—a joint mission of the European Space Agency (ESA) and the Russian space agency Roscosmos. It was built in Italy and was intended to test technology for future soft landings on the surface of Mars. It also had a limited but focused science payload that would have measured atmospheric electricity on Mars and local meteorological conditions.
