Mars Mysteries: Unveiling the Icy Craters

Mars Mysteries: Unveiling the Icy Craters
Over the past two decades, HiRISE and the Context Camera on MRO have catalogued hundreds of new impact craters. Some of these recent craters, particularly in the mid- to high-latitudes, have excavated buried water-ice that typically is exposed within the crater cavity.

HiRISE and the Context Camera are always on the lookout for new impact craters. New impacts can be identified by comparing images of the same region taken at different times (typically years apart) and looking for visual clues of recent impacts.

Many craters in the mid-latitudes of Mars are partially filled with deposits that have been interpreted to be ice-rich.

A 150-meter diameter impact crater formed on Mars on 24 December 2021. This is likely the largest new crater to have formed on Mars during the era of frequent spacecraft imaging.
