Curiosity Rover: One Year on Mars

Exploring Mars

NASA's Curiosity rover survived "seven minutes of terror" and landed safely in an ancient Martian crater. Like a tourist in a new land, the mobile science laboratory spent its first year sightseeing and exploring its surroundings. It zapped its laser at boulders, drilled into rocks, measured radiation and tracked the weather. It achieved one of the mission's main goals by finding evidence that Gale Crater once had an environment suitable to support simple life. The six-wheel, nuclear-powered rover is now headed for a mountain, a drive that will take many months. Here's a gallery of images from Curiosity's landing and past year on Mars.

Measurements of the Martian air by the rover found it's mostly made of carbon dioxide with traces of other gases, according to two studies appearing in the Friday, July 19, 2013 issue of the journal Science.
