Showing its capability, HiRISE reveals the Opportunity rover near the rim of Victoria Crater in Meridiani Planum, as well as its shadow on the Martian surface and wheel tracks in the Martian soil behind it. The HiRISE image also reveals eroded segments of the crater rim and other landscape features in great detail.
