Impact Melt in Raditladi Basin


We have seen the ejecta deposit of the Raditladi basin before, but not at this resolution. Here, the smooth patches of surface are solidified ponds of impact melt, rock liquefied by the tremendous heat of the impact explosion that formed Raditladi. The rougher, higher-standing terrain is either solid ejecta deposited around the impact site, or part of the original surface that predates the basin's formation.
