The ESA's Mars Express probe has been surveying Mars from orbit for more than twenty years. The way it has mapped the surface using its High Resolution Stereo Camera (HRSC) has drastically changed the way we see the Red Planet. In a recent article, the ESA shared a series of HRSC images highlighting the heavily cratered region known as Arabia Terra. The study of Martian craters offers insight into Mars' geology, meteorology, and its long and turbulent history. The images were generated from the camera's digital terrain model and the nadir and colour channels.
