This image shows a triple crater in Noachis Terra, Mars. The largest crater measures 45 km across, and the smallest 28 km. There are also signs of other sizeable craters, such as the round patches of sunken surface seen to the top right and bottom left. This image comprises data gathered by ESA’s Mars Express using its High Resolution Stereo Camera (HRSC) on August 6, 2020. This image was created using data from the nadir and color channels of the HRSC. The nadir channel is aligned perpendicular to the surface of Mars, as if looking straight down at the surface. North is to the right. Image credit: ESA / DLR / FU Berlin / CC BY-SA 3.0 IGO.
