ExoMars Trace Gas Orbiter has returned the first images of the Red Planet from its new orbit. The orbiter’s Colour and Stereo Surface Imaging System, CaSSIS, took this stunning image, which features part of an impact crater, during the instrument’s test period. The camera was activated on 20 March and was tested for the start of its main mission on 28 April..
The image captures a 40 km-long segment of
Korolev Crater located high in the northern hemisphere. The bright material on the rim of the crater is ice.[/quote]
