ExoMars
ExoMars is part of the ESA's Aurora Flagship sequence of exploratory missions.
The first phase of the ExoMars began in 2016 when the Trace Gas Orbiter was launched. This phase was also designed to land a rover to carry out a number of scientific experiments, but the rover failed to land safely. The Trace Gas Orbiter began its science mission in 2018. It looks for signs of gases in Mars' atmosphere that could be produced by biological activity.
The second phase is scheduled to launch in 2020. It will consist of a stationary lander and a rover equipped with a drill allowing it to collect samples at a depth of 2 meters.
