setiinstitute, #PPOD: Martian Rhapsody in Blue
Some mind-boggling details of a Martian impact crater taken by NASA's HiRISE camera onboard the Mars Reconnaissance Orbiter. This image has everything: layers, boulders, dunes, and maybe some polygonal terrain, too. The blue filter is used here to learn about morphologies, textures, and composition.
