The total distance driven by NASA's Mars rover Curiosity passed the one-mile mark a few days before the first anniversary of the rover's landing on Mars.

This sequence of images shows a blast zone where the sky crane from NASA's Curiosity rover mission hit the ground after setting the rover down in August 2012, and how that dark scar's appearance ch...

This graph shows the rise and fall of air and ground temperatures on Mars obtained by NASA's Curiosity rover.

The Martian soil examined by the Chemistry and Mineralogy (CheMin) instrument on NASA's Curiosity rover shows the diffraction signature, or "fingerprint," of the mineral olivine, shown here on Eart...

This "thumbnail" image illustrates the size of the first image expected from NASA's Curiosity rover. It was taken by a rover engineering model during a test session in the Mars Yard at NASA's Jet P...

This view of Curiosity's left-front and left-center wheels and of marks made by wheels on the ground in the "Yellowknife Bay" area comes from one of six cameras used on Mars for the first time more...

This image from the Mars Hand Lens Imager (MAHLI) camera on NASA's Curiosity Mars rover shows an example of a type of geometrically distinctive feature that researchers are using Curiosity to exami...

The Curiosity engineering team created this view from images taken by NASA's Curiosity rover rear hazard avoidance cameras underneath the rover deck on Sol 0.

Access Mars allows any member of the public to explore the discoveries of NASA's Curiosity rover.

Modern-day Mars experiences cyclical changes in climate and, consequently, ice distribution. Unlike Earth, the obliquity (or tilt) of Mars changes substantially on timescales of hundreds of thousan...

An image taken at the "Hidden Valley" site, en-route to Mount Sharp, by NASA's Curiosity rover.

This view from the Mars Hand Lens Imager (MAHLI) on the arm of NASA's Curiosity Mars rover shows texture within a light-toned vein at a site called "Garden City" on lower Mount Sharp.

On Cape Canaveral Air Force Station in Florida, the payload fairing protecting NASA's Mars Science Laboratory (MSL) stands atop the 197-foot-tall United Launch Alliance Atlas V rocket, which is rea...

The Atlas V rocket set to launch NASA's Mars Science Laboratory (MSL) mission is illuminated inside the Vertical Integration Facility at Space Launch Complex 41, where employees have gathered to ho...

Curiosity logs 5K after a punishing trek over sharp terrain. To celebrate, JPLers put on their running shoes!

After a rocket-powered descent stage, also known as the sky crane, delivered NASA's Curiosity rover to Mars on Aug. 5 PDT (Aug. 6 EDT), 2012, it flew away and fell to the surface.

Pictured here are some of the women working on the Curiosity rover. The picture was taken in the working "garage" where Curiosity's ground test rover is housed in the "Mars Yard," a simulated mart...

Clara Ma poses with a model of Curiosity.

This graphic shows the flux of radiation detected by NASA's Mars Science Laboratory on the trip from Earth to Mars from December 2011 to July 2012.

This is the highest-resolution view that the Mars Hand Lens Imager (MAHLI) on NASA's Mars rover Curiosity acquired of the top of a rock called "Bathurst Inlet."

Measurements with the MSL Radiation Assessment Detector (RAD) on NASA's Curiosity Mars rover during the flight to Mars and now on the surface of Mars enable an estimate of the radiation astronauts ...
