From over 100 miles above the surface, a NASA satellite spotted dry ice and gullies inside a Martian Crater.
In this image, wintertime CO2 frost is found closer to the equator, where it’s usually a bit too”warm” for dry ice to exist. But inside parts of the crater that receive less sunlight, frost has formed.
Cold as (dry) ice: Mars Reconnaissance Orbiter glimpsed patches of carbon dioxide frost in the shadows beneath a crater rim, according to NASA Mars.
