@HiRISE
Any idea how old those fresh craters are in the upper middle of the image? They make me not want to have a house on the surface until Mars gets a nice, thick atmosphere.
@jurban Good question: they are small enough to be more "recent" since the era of large bombardments is long over. While still visible, they are clearly filled in with material and we cannot see any ejecta, so it could be centuries old. 🤯
