This image captures the western side of a relatively young “rampart” crater in the
Tharsis region. Rampart craters are surrounded by a !uidized ejecta blanket (an ejecta
blanket is the material thrown out around a crater when the impact occurs, in this case
resembling the whites of a fried egg, where the crater is the yolk). Researchers speculate
that these may form when an object impacts ground that contains !uid (liquid or
frozen) that is released upon impact.
