Colorful Bedrock in a Northern Plains Crater
Free
About
This image covers the inside of an impact crater on the northern plains of Mars. It was intended to provide a baseline image of sand dunes on the crater floor, which could be monitored for potential motion in future pictures. Much more than sand is visible. The dark, undulating dunes sit atop a colorful surface of exposed bedrock. Based on the crater's diameter of roughly 25 kilometers, these rocks may have been previously buried over a mile beneath the surface. The varying colors likely reflect diverse mineral compositions. (The CRISM instrument, also on MRO, has detected different minerals in the neighboring larger Micoud Crater, whose rim lies about 50 kilometers east-southeast of this im — NASA JPL · 2020.
