OPP-SOL367-MyTracks.jpgFarewell Endurance! (false colors)114 visiteGrazie alla fantasia e ad una buona dose di inventiva di qualche Collaboratore del Sito "Mars Daily", abbiamo il piacere di offrirVi questa visione in falsi (ma comunque credibili) colori delle tracce lasciate dal Rover Opportunity durante il suo cammino verso il Vostok Crater.
In questo frame, in maniera particolare, si possono vedere ancora bene le pareti esterne del Cratere Endurance. Eravamo nel Sol 367 di Opportunity.

This image was acquired on Dec. 22, 2023 (Sol 1009) at the Local Mean Solar Time of 12:28:42.

PSP_010200_1805_RED_abrowse-00.jpgFresh Crater Cluster (CTX Frame - Natural Colors; credits: Dr Paolo C. Fienga - Lunexit Team)64 visiteAlthough most of the craters HiRISE usually images are ancient, impact cratering is an ongoing process on the Martian Surface.
While very large craters are rare, smaller ones with diameters of a few meters form on timescales rapid enough for Mars missions to confirm the presence of a new crater. Data from the Mars Orbiter Camera (MOC) on the (now defunct) Mars Global Surveyor, the Context Camera (CTX) on MRO, and HiRISE have dated craters to within a few years or even months, based on repeat images that show no craters in the earlier image and craters present in the later image.
Most of the new craters identified by CTX and HiRISE have been located in Mars' dustiest areas, where a new impact will scour dust from the Surface and reveal darker underlying rock. This color difference makes the craters easier to spot. Other, less dusty areas of Mars are certainly being bombarded as well, but the size of the craters makes them difficult to detect without stark color contrasts.
Once a new dark spot has been identified by CTX, HiRISE will take a follow-up image to confirm that the dark spots are in fact Impact Craters.MareKromium
