Sometimes, even rovers on Mars stop to admire the scenery. Just late last November the Curiosity rover on Mars paused to photograph its impressive surroundings. One thing to admire, straight ahead, was Central Butte, an unusual flat hill studied by Curiosity just a few days before this image was taken. To its right was distant Mount Sharp, the five-kilometer central peak of entire Gale crater, the interior of which Curiosity is exploring. Mount Sharp, covered in sulfates, appears quite bright in this colorized, red-filtered image. To the far left, shrouded in a very dark shadow, was the south slope of Vera Rubin ridge, an elevation explored previously by Curiosity. Between the ridge and butte were tracks left by Curiosity's wheels as they rolled forward, out of the scene. In the image foreground is, of course, humanity's current eyes on Mars: the complex robotic rover Curiosity itself. Later this year, if all goes well, NASA will have another rover -- and more eyes -- on Mars. Today you can help determine the name of this rover yourself, but tomorrow is the last day to cast your vote. Help Name the Mars 2020 Rover: Vote here!
