This annotated artists' concept shows the location of all of the Curiosity rover's 17 cameras.

No bones about it! Seen by Mars rover Curiosity using its MastCam, this Mars rock may look like a femur thigh bone. Mission science team members think its shape is likely sculpted by erosion, eithe...

A Martian target rock called "Nova," shown here, displayed an increasing concentration of aluminum as a series of laser shots from NASA's Curiosity Mars rover penetrated through dust on the rock's ...

This image is from a test series used to characterize the 100-millimeter Mast Camera on NASA's Curiosity rover. It was taken on Aug. 23, 2012, and looks south-southwest from the rover's landing site.

Open Parachute During Tests for Mars Science Laboratory

This diagram shows how materials analyzed by ChemCam during the first 100 Martian days of the mission (Aug. 5, 2012, to Nov. 16, 2013) differed with regard to hydrogen content (horizontal axis) and...

The Radiation Assessment Detector (RAD) instrument on NASA's Curiosity Mars rover monitors the natural radiation environment at the surface of Mars.

This wide view of the 'John Klein' location selected for the first rock drilling by NASA's Mars rover Curiosity is a mosaic taken by Curiosity's right Mast Camera (Mastcam) during the afternoon of ...

This view of the lower front and underbelly areas of NASA's Mars rover Curiosity combines nine images taken by the rover's Mars Hand Lens Imager (MAHLI) during the 34th Martian day, or sol, of Cur...

The heat shield for NASA's Mars Science Laboratory is the largest ever built for a planetary mission.

Sensors on two finger-like mini-booms extending horizontally from the mast of NASA's Mars rover Curiosity will monitor wind speed, wind direction and air temperature.

This stereo view from NASA's Curiosity Mars Rover shows the downwind side of a dune about 13 feet high within the Bagnold Dunes on Mars. The image appears three-dimensional when viewed through red-...

While Curiosity continues to blaze a trail to Mount Sharp, the rover takes time to shoot a Martian moon movie.

This May 12, 2014, view from the Mars Hand Lens Imager (MAHLI) in NASA's Curiosity Mars Rover shows the rock target "Windjana" and its immediate surroundings after inspection of the site by the rov...

This graphic compares the radiation dose equivalent for several types of experiences, including a calculation for a trip from Earth to Mars based on measurements made by the Radiation Assessment De...

In this image from NASA's Curiosity rover, a rock outcrop called Link pops out from a Martian surface that is elsewhere blanketed by reddish-brown dust. The fractured Link outcrop has blocks of exp...

As the last step in a series of inspections of the Mars Hand Lens Imager (MAHLI) aboard NASA's Mars rover Curiosity, this camera's reclosable dust cover was opened for the first time during the 33r...
