NASA and the European Space Agency are jointly developing the ExoMar Trace Gas Orbiter mission for launch in 2016. This is an artist's concept of the planned spacecraft, which will carry five science instruments plus a European entry, descent and landing demonstrator vehicle. The orbiter will also serve as a communications relay for Mars surface missions.
