This self-portrait of NASA's Curiosity Mars rover taken on Jan. 31, 2018, shows the vehicle on Vera Rubin Ridge, which it had been investigating for the previous several months. Poking up just behind Curiosity's mast is Mount Sharp, photobombing the robot's selfie. Curiosity landed on Mars five years ago with the intention of studying lower Mount Sharp, where it will remain for all of its time on Mars. The mountain's base provides access to layers formed over millions of years. These layers formed in the presence of water -- likely due to a lake or lakes that sat at the bottom of the mountain, which sits inside of Gale Crater.
