Trace Gas Orbiter

(TGO, ExoMars Trace Gas Orbiter, ExoMars TGO)
(ESA and Russian Mars orbiter-probe launched in 2016)

The Trace Gas Orbiter (TGO, ExoMars Trace Gas Orbiter or ExoMars TGO) is a Mars orbiter to measure methane and other gases of interest in the Martian atmosphere. It was launched in 2016 aiming at a 7-year operational life, by the European Space Agency (ESA) and Roscosmos, as part of their ExoMars program of Mars exploration. It was launched and transported to Mars along with Schiaparelli, a prototype landing vehicle that failed to land soft enough to function afterward.

TGO instruments:

MAGE (the Mars Atmospheric and Gravity Experiment) is an investigation using data extracted from its radio-based navigation/tracking, in particular to retrieve gravity anomaly data, including changes in ice caps over time, and also data regarding the atmosphere from its effect on aerobraking (modifying the orbit using interaction with the atmosphere).
