This picture of the Martian landing site of NASA's Curiosity rover puts a color view obtained by the rover in the context of a computer simulation derived from images acquired from orbiting spacecr...

With the wheels and suspension system already installed onto one side of NASA's Mars rover Curiosity the previous day, spacecraft engineers and technicians prepare the other side's mobility subsyst...

This map shows the route driven by NASA's Mars rover Curiosity through the 901 Martian day, or sol, of the rover's mission on Mars (February, 18, 2015).

This map shows the route driven by NASA's Curiosity Mars rover from the "Bradbury Landing" location where it landed in August 2012 to the "Pahrump Hills" outcrop where it drilled into the lowest pa...

In this image, a large, six-wheeled rover sits on a concrete floor in a laboratory against a light-blue background. The rover's 'legs,' or mobility system are a medium blue color and the large, cle...

Patches of Martian sandstone visible in the lower-left and upper portions of this view from the Mast Camera (Mastcam) of NASA's Curiosity Mars rover have a knobbly texture due to nodules apparently...

On Cape Canaveral Air Force Station in Florida, the 197-foot-tall United Launch Alliance Atlas V rocket is in place at Space Launch Complex 41 after rolling out from the nearby Vertical Integration...

This false-color map shows the area within Gale Crater on Mars, where NASA's Curiosity rover landed on Aug. 5, 2012 PDT (Aug. 6, 2012 EDT).

These images from the NASA Mars Reconnaissance Orbiter show several impact scars on Mars made by pieces of the NASA Mars Science Laboratory spacecraft that the spacecraft shed just before entering ...

This collage shows the variety of soils found at landing sites on Mars.

This oblique, southward-looking view of Gale crater shows the landing site and the mound of layered rocks that NASA's Mars Science Laboratory will investigate.

The left-front wheel of NASA's Curiosity Mars rover shows dents and holes in this image taken during the 469th Martian day, or sol, of the rover's work on Mars (Nov. 30, 2013).

Researchers prepare for a test of the Chemistry and Camera (ChemCam) instrument that will fly on NASA's Mars Science Laboratory mission. The instrument uses a pulsed laser beam to vaporize a pinhea...

This July 22, 2016, stereo scene from the Mastcam on NASA's Curiosity Mars Rover shows boulders at a site called "Bimbe" on lower Mount Sharp. They contain pebble-size and larger rock fragments. Th...

This animation shows the major mission events of the Curiosity rover's landing on Mars. (Audio: music and mechanical sounds only)

The sand dunes on Earth sometimes resemble those on Mars. However, Martian dunes are many times larger than those we see on Earth. This image shows engineers seeking out the best place to test dr...

This topography map shows a portion of the Gale Crater region on Mars, where NASA's Mars Curiosity rover landed on August 6, 2012.

NASA's InSight arrives at Vandenberg AFB and readies for launch, Opportunity uses its abrasion tool for the first time in 300 sols, and Curiosity celebrates 2,000 Martian days on the Red Planet.

Excitement builds at NASA’s Jet Propulsion Laboratory when news of a successful parachute deployment from the Mars Science Laboratory spacecraft reaches the science team.

NASA's Mars rover Curiosity used its Mast Camera (Mastcam) to take the images combined into this mosaic of the drill area, called "John Klein."
