These two views from NASA’s Curiosity rover, acquired specifically to measure the amount of dust inside Gale Crater, show that dust has increased over three days from a major Martian dust storm.

Employees at Space Launch Complex 41 of Cape Canaveral Air Force Station, Fla., keep watch as the payload fairing containing NASA's Mars Science Laboratory spacecraft is lifted up the side of the V...

This artist concept features NASA's Mars Science Laboratory Curiosity rover.

This artist's scoreboard displays a fictional game between Mars and Earth, with Mars in the lead. It refers to the success rate of sending missions to Mars, both as orbiters and landers.

This pair of images shows a "bite mark" where NASA's Curiosity rover scooped up some Martian soil (left), and the scoop carrying soil.

The surface of the Martian rock target in this stereo, close-up image from the Curiosity rover's MAHLI camera includes small hollows with a "swallowtail" shape characteristic of gypsum crystals. Th...

Use geometric shapes called tangrams to build a rover and other space-themed designs!

NASA’s Curiosity Mars rover used its Mastcam to take an image of this mountain, nicknamed “Rafael Navarro Mountain” after the astrobiologist Rafael Navarro-González, who worked on the mission until...

NASA's Curiosity rover uses SAM to make the most sensitive measurements ever to search for methane gas on the red planet.

This simulation shows the first test drive of NASA's Curiosity rover. This tool, called the Rover Sequencing and Visualization Program (RSVP) helps engineers plan the rover's drives, modeling pebbl...

NASA's Curiosity Mars rover and tracks left by its driving appear in this portion of a Dec. 11, 2013, observation by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Re...

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."

This small ridge, about 3 feet long, appears to resist wind erosion more than the flatter plates around it. Such differences are among the traits NASA's Curiosity Mars rover is examining at selecte...

Testing of the cruise stage for NASA's Mars Science Laboratory in August 2010 included a session in a facility that simulates the environment found in interplanetary space.

In the Vertical Integration Facility at Space Launch Complex 41, the payload fairing containing NASA's Mars Science Laboratory spacecraft was attached to its Atlas V rocket on Nov. 3, 2011.

This animation shows a proposed route for NASA's Curiosity rover, which is climbing lower Mount Sharp on Mars. The annotated version of the map labels different regions that scientists working with...

NASA’s Curiosity Mars rover used its black-and-white navigation cameras to capture panoramas of this scene at two times of day. Blue, orange, and green color was added to a combination of both pano...

Curiosity performs a series of firsts this week -- flexing its arm, laser-zapping a rock and rolling on its wheels.

This grouping of two test rovers and a flight spare provides a graphic comparison of three generations of Mars rovers developed at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The setting is ...

Preparation for Testing of Mars Landing Radar

Scarecrow is a full-scale version of Curiosity, but without the “brains.” Engineers use it to test drive on different types of terrain. In this image, the rover was taken out to the Dumont Dunes in...

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 ...

The left eye of the two-camera Mast Camera (Mastcam) instrument on NASA's Mars rover Curiosity took the images combined into this mosaic of the rover's upper deck.
