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.
