New Mars view exposes Arabia Terra's ancient cratered heart

ESA's Mars Express released a richly processed color/topographic image of Arabia Terra (Oct. 12, 2024, HRSC) showing the Red Planet's ancient highlands with Trouvelot Crater at the center and a nearby older, eroded basin. The scene highlights mafic rocks, wind-sculpted dunes, and a light-toned mound that may reveal water-related minerals, illustrating billions of years of impact, volcanism and erosion in this region, and emphasizing the ongoing scientific value of reprocessing archived data rather than a brand-new snapshot.

Exploring Martian Volcano's Flank Chasms.

ESA's Mars Express has captured images of the pitted, fissured flank of Ascraeus Mons, the second-tallest volcano on Mars. The volcano's peak is found to the right of the frame, with lava flows and tubes, chains of craters, channel-like rilles, and large fissures spanning tens of km in length visible across the frame. The High Resolution Stereo Camera (HRSC) responsible for these new images has revealed much about Mars' diverse surface features, including wind-sculpted ridges and grooves, impact craters, tectonic faults, river channels, and ancient lava pools.
