Winter Frost

May 28, 2014
Right past the sharp, but warped rim of this ancient impact crater are deposits of winter frost, which show up as blue in enhanced color.

There are two possible science goals that we can study here: what does the terrain look like during the Martian summer, because HiRISE resolution can track changes over time. And second, could the gullies in this crater be a reasonable place to look for recurring slope lineae (or RSL) to occur? The slopes of certain craters have been home these phenomena in other regions as well.

Note: the images here are not map-projected, so approximate north is down.
