Launched 10 years ago, NASA’s Mars Reconnaissance Orbiter has encircled Mars 40,000 times and counting – returning to scientists not only mounds of weekly data but also stunning images of the planet’s surface. The spacecraft’s High Resolution Imaging Science Experiment (HiRISE) camera captured the following photographs of Mars’ diverse exterior, revealing the frost-coated gullies, wind-crafted slopes, cascading dunes, and jagged impact craters of the Red Planet.
