ExoMars ready to sniff out life on Mars

ESA's mission to search for signs of life that may have existed on the Red Planet enters its final, most crucial stage.

The first mission of European Space Agency’s (ESA) ExoMars programme is set to complete its seven-month journey to the Red Planet today.

The spacecraft comprises two separate instruments: the Trace Gas Orbiter (TGO) and the Schiaparelli landing demonstration module. Once in orbit the TGO will perform detailed observations of the Martian atmosphere, searching for evidence of gases indicative of the existence of biological life, such as methane.

Also, at this point the Schiaparelli lander will be ejected from the orbiter towards the Red Planet, entering the atmosphere at 21,000km/h before using a combination of thrusters, aerobraking and parachutes to land on the surface. Once safely on solid ground, the lander will deploy its payload of scientific instruments to take measurements the atmospheric conditions on the surface.

The lander will only remain operable for a few days but the TGO will stay in orbit for five years, waiting for the arrival of a second rover in 2020 that will drill into the surface of the Red Planet.
