It has separated from mother and is now facing a baptism of fire as it heads towards the surface of the Red Planet.
The Mars lander Schiaparelli is due to touch down Wednesday as part of the ExoMars missions -- a joint venture between the European Space Agency (ESA) and Russian state corporation Roscosmos.
Schiaparelli's companion ship -- the Trace Gas Orbiter -- will stay in orbit, trying to find out more about methane and other gases on Mars that could be signatures of life, or geological processes.
In 2014, NASA's Curiosity rover detected a large spike in the amount of methane. ESA scientists hope that the ExoMars missions can shed light on what might be causing it.
