Ready for an intergalactic adventure? Take this virtual flight over Mariner Valley, Mars’s version of the Grand Canyon, a geological feature as deep as Mt. Everest and as wide as the distance from New York to Los Angeles. Kind of makes Earth’s biggest dry river bed seem a bit less “Grand,” doesn’t it?

This video, created by the Jet Propulsion Laboratory, includes a mosaic image of the Mariner Valley that was compiled at Arizona State University using photos taken by the Thermal Emission Imaging System (THEMIS) from NASA’s Mars Odyssey orbiter.
