Video: Flight over Korolev Crater on Mars
This movie was created using an image mosaic made from single orbit observations from the High Resolution Stereo Camera (HRSC) on Mars Express, which was first published in December 2018. The mosaic combines data from the HRSC nadir and colour channels; the nadir channel is aligned perpendicular to the surface of Mars, as if looking straight down at the surface.

Image: Sculpted by nature on Mars
Nature is a powerful sculptor—as shown in this image from ESA’s Mars Express, which portrays a heavily scarred, fractured Martian landscape. This terrain was formed by intense and prolonged forces that acted upon Mars’ surface for hundreds of millions of years. Source: https://phys.org/news/2020-05-image-sculpted-nature-mars.html…
