ExoMars Rover completes environmental tests
(PHYSorg.com Space & Earth)

The Rosalind Franklin rover of the joint ESA-Roscosmos ExoMars mission completed a series of environmental tests at the end of 2019 at Airbus, Toulouse, France. This included final thermal and vacuum tests where the Rover is heated and cooled to simulate the temperatures of its journey through space and on the surface of Mars. For example, Rosalind Franklin can expect temperatures dropping to -120°C outside, and -50 °C inside the rover once on Mars. It must also be able to operate in less than one hundredth of Earth`s atmospheric pressure-and in a carbon dioxide-rich atmosphere.
