Click here for the latest information on the ExoMars mission.Establishing if life ever existed on Mars is one of the outstanding scientific questions of our time. To address this important goal, ESA has established the ExoMars programme to investigate the martian environment and to demonstrate new technologies paving the way for a future Mars sample return mission in the 2020s.There are two missions in the ExoMars programme: one comprises the Trace Gas Orbiter (TGO) plus an Entry, Descent and Landing Demonstrator Module (EDM), dubbed Schiaparelli, launched in 2016, and the other, comprising a rover, with a launch date of 2018. Both missions are in cooperation with Roscosmos.The 2016 ExoMars/TGO carries scientific instruments to detect and study atmospheric trace gases, such as methane. EDM contains sensors to evaluate the lander’s performance as it descends, and additional sensors to study the environment at the landing site.In addition to its prime science mission, the orbiter also carries a sophisticated radio relay capability provided by NASA. The Electra Proximity Payload (Electra) is a telecommunications package that acts as a communications relay and navigation aid.
