Carbon Dioxide Frost on Mars


The image of the day for November 8th is a satellite image from the Mars Reconnaissance Orbiter. Through the HiRISE sensor, the MRO is able to capture visible light with a resolution of 1m. The image captures a rust colored crater covered with CO2 frost from the Martian atmosphere. During the spring, frost only remains on the slopes of the craters that are facing south. As the frost melts the rising gas brings dark colored sand from lower levels of the soil, leaving a banded appearance at the surface.
