ExoMars Trace Gas Orbiter is ESA’s most sophisticated Mars explorer. Here are the key facts and figures from a decade in Mars orbit.
On 19 October 2016, the Trace Gas Orbiter was inserted into an elliptical orbit around Mars.
The main objectives of this mission are to search for evidence of methane and other trace atmospheric gases that could be signatures of active biological or geological processes and to test key technologies in preparation for future Mars missions, including the ExoMars Rosalind Franklin rover mission.
