A year ago, 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.

This image provided by NASA/JPL-Caltech/Univ. of Arizona, shows tracks from the first drives of NASA's Curiosity rover, captured by the High-Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. The image's color has been enhanced to show the surface details better. The two marks seen near the site where the rover landed formed when reddish surface dust was blown away by the rover's descent stage, revealing darker basaltic sands underneath. Similarly, the tracks appear darker where the rover's wheels disturbed the top layer of dust. Observing the tracks over time will provide information on how the surface changes as dust is deposited and eroded. (AP Photo/NASA/JPL-Caltech/Univ. of Arizona)

This image provided by NASA/JPL-Caltech shows the surroundings of the location where NASA Mars rover Curiosity arrived on Sept. 4, 2012. It is a mosaic of images taken by Curiosity's Navigation Camera (Navcam) following the Sol 29 drive of 100 feet. About 9 feet apart, tracks from the drive are visible in the image.

This Wednesday, Sept. 19, 2012 photo provided by NASA shows a rock about 8 feet (2.5 meters) in front of the Curiosity rover on Mars. The rock is about 10 inches (25 centimeters) tall and 16 inches (40 centimeters) wide. The team has assessed it as a suitable target for the first use of Curiosity's contact instruments on a rock, and named it after the late Jacob Matijevic, who was the surface operations systems chief engineer for the Mars Science Laboratory Project and the project's Curiosity rover.

This combination of artist's renderings released by NASA/JPL-Caltech shows how NASA's Curiosity rover is expected to approach and land on Mars. The second from top photo shows an illustration of signals beamed back to Earth and subsequent images show the descent stage and "sky crane" lowering it to the surface. (AP Photo/NASA/JPL-Caltech)
