EXOMARS
ExoMars (Exobiology on Mars) is a large Mars mission to search for biosignatures of Martian life, past or present. This astrobiology mission is currently under development by the European Space Agency (ESA) in collaboration with the Russian Federal Space Agency (Roscosmos).The programme includes several spacecraft elements to be sent to Mars on two launches. The ExoMars Trace Gas Orbiter (TGO) and an EDM stationary lander called ‘Schiaparelli’ are planned for 2016. The TGO would deliver the ESA-built stationary lander and then proceed to map the sources of methane on Mars and other gases, and in doing so, help select the landing site for the ExoMars rover to be launched on 2018 on a Russian heavy lift Proton launch vehicle. The TGO will feature four instruments and will also act as the communication relay satellite for the follow up rover. In 2018 a Roscosmos-built lander is to deliver the ESA-built rover to the martian surface. The rover will also include some Roscomos built instruments.
