This short, relaxing, mesmerizing video of an Martian impact crater called Aram Chaos was taken by the HiRISE camera on the Mars Reconnaissance Orbiter. The images were run through an enhanced color red-green-blue filter, which tends to highlight the structure and geology rather than the true color. For example, the blue in the video often represents basalt, an igneous rock of volcanic origin.
