ExoMars Rover schließt Umgebungstests ab

Zum Ende des Jahres 2019 hat der Rover Rosalind Franklin bei Airbus in Toulouse eine Reihe von Vorbereitungstests für den Flug zum Roten Planeten erfolgreich absolviert. Während der Tests wurde der Rover aufgeheizt und abgekühlt, um die großen Temperaturschwankungen auf seiner Reise durch das Weltall und auf der Marsoberfläche zu simulieren. So muss der Rosalind Franklin beispielsweise mit Temperaturen von -120°C außerhalb und -50°C innerhalb des Rovers auf dem Mars rechnen und in der Lage sein, in weniger als einem Hundertstel des atmosphärischen Drucks der Erde zu funktionieren – und das in einer kohlendioxidreichen Atmosphäre.

ExoMars Rover completes environmental tests

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.

At the very centre of the disc, close to the black hole, a region of very hot electrons – with temperatures of around a billion degrees – known as the corona produced high-energy X-rays that stream out into space.
