The Cerberus Fossae are a group of troughs in the Cerberus region of Mars that run roughly parallel to one another. They formed due to extension of the crust in the region. Some of the troughs, suc...

The HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter was able to capture this image of NASA’s Perseverance rover on the surface of Mars.

These three views of the Martian moon Phobos were taken by NASA's 2001 Mars Odyssey orbiter using its infrared camera, THEMIS. Each color represents a different temperature range.

NASA's Mars rover Curiosity drove 6.2 feet (1.9 meters) during the 100th Martian day, or sol, of the mission (Nov. 16, 2012). The rover used its Navigation Camera after the drive to record the imag...
