This sequence of images from the Front Hazard-Avoidance Camera on NASA's Mars rover Curiosity shows the rover drilling into rock target 'Cumberland.' The drilling was performed during the 279th Mar...

Since landing on Mars in August 2012, NASA's Curiosity rover has been exploring 3-mile-high Mt. Sharp in Gale Crater.

Sunset on Mars catches NASA's Mars Science Laboratory in the foreground in this artist's concept. The mission is under development for launch in 2009 and a precision landing on Mars in 2010.

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.

This set of images from Mars shows the handiwork of different tools on three missions to the surface of Mars.

This artist's concept shows how the cruise stage de-spins outside the martian atmosphere, turns to entry position, suffers peak heating just after entry, then peak deceleration, before deploying a ...

NASA's Mars Science Laboratory rover Curiosity appears as a bluish dot near the lower right corner of this enhanced-color view from the High Resolution Imaging Science Experiment (HiRISE) camera on...

This set of images illustrates the twin cameras of the Mast Camera (Mastcam) instrument on NASA's Curiosity Mars rover (upper left), the Mastcam calibration target (lower center), and the locations...

This rock encountered by NASA's Curiosity Mars rover is an iron meteorite called "Lebanon," similar in shape and luster to iron meteorites found on Mars by the previous generation of rovers, Spirit...

This is the first image taken by the Navigation cameras on NASA's Curiosity rover. It shows the shadow of the rover's now-upright mast in the center, and the arm's shadow at left. The arm itself ca...

NASA's Curiosity Mars rover examined both the "Greenhorn" and "Big Sky" targets with the rover's Alpha Particle X-ray Spectrometer (APXS) instrument. Greenhorn is located within an altered fracture...

NASA's Mars rover Curiosity captured this 360-degree view using its Navigation Camera (Navcam) after a 17-foot (5.3 meter) drive on 477th Martian day, or sol, of the rover's work on Mars (Dec. 8, 2...

NASA engineers take the Curiosity test rover to California's Mojave desert to learn how to drive on Martian sand dunes.

This mosaic from the Mast Camera on NASA's Curiosity rover shows a close-up view looking toward the "Glenelg" area, where three different terrain types come together.

This scene combines seven images from the telephoto-lens camera on the right side of the Mast Camera (Mastcam) instrument on NASA's Mars rover Curiosity.

Curiosity viewed sloping buttes and layered outcrops as it exited the "Murray Buttes" region on lower Mount Sharp, Sept. 9, 2016.

The Mars Science Laboratory flight system will consist of four major elements in three distinct phases (from left): the cruise stage, the aeroshell (heatshield and backshell), the descent stage, an...

Mars is experiencing large regional dust storms over its northern hemisphere during the past week.

Large Parachute for NASA's Mars Science Laboratory

Sulfates are found overlying clay minerals in sediments within Columbus Crater, a depression that likely hosted a lake in the past.

The Mars Science Laboratory mission's "powered descent vehicle" is the integrated combination of the spacecraft's descent stage and the rover Curiosity. It is shown inside the Payload Hazardous Ser...

This view shows the patch of veined, flat-lying rock selected as the first drilling site for NASA's Mars rover Curiosity.
