Curiosity is the biggest robot explorer ever to rove Mars. How do you power something like that?

The right Mast Camera (Mastcam) of NASA's Curiosity Mars rover provided this contextual view of the vicinity of the location called "John Klein," selected as Curiosity's first drilling site.

This video of thumbnail images from the Mars Descent Imager (MARDI) on NASA's Curiosity rover shows the heat shield dropping away from the rover on Aug. 5 PDT (Aug. 6 EDT). It covers the first 25 s...

A wheel track cuts through a windblown ripple of dusty sand in this Nov. 7, 2014, image from the Mastcam on NASA's Curiosity rover. The view spans about four feet across. This experiment was planne...

The Sample Analysis at Mars instrument suite will weigh about 83 pounds (38 kilograms) and make up about half the science payload of the Mars Science Laboratory mission. It is a suite of three inst...

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

Twenty-one times during the first 12 weeks that NASA's Mars rover Curiosity worked on Mars, the rover's Rover Environmental Monitoring Station (REMS) detected brief dips in air pressure that could ...

"Vera Rubin Ridge," a favored destination for NASA's Curiosity Mars rover even before the rover landed in 2012, rises near the rover nearly five years later in this panorama from Curiosity's Mast C...

This stereo view from NASA's Mars rover Curiosity shows a rock called "Link," which bears rounded pebbles that provide evidence about vigorous flow of water in a stream on ancient Mars.

The Mars Science Laboratory (MSL) team in the MSL Mission Support Area react after learning the Curiosity rover has landed safely on Mars and images start coming in at the Jet Propulsion Laboratory...

In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, technicians process the backshell for NASA's Mars Science Laboratory (MSL).

By monitoring weather through two Martian years since landing in Gale Crater, NASA's Curiosity Mars rover has documented seasonal patterns in variables such as temperature, water-vapor content and ...

This image from NASA's Curiosity rover shows the great diversity of grains found on the surface of a Martian rock.

This graphic from NASA's Curiosity mission shows an analysis of the composition of two rocks called "Crest" and "Rapitan" in the "Yellowknife Bay" area of Mars.

This photograph of the NASA Mars Science Laboratory rover, Curiosity, was taken during mobility testing on June 3, 2011. The location is inside the Spacecraft Assembly Facility at NASA's Jet Propul...

Curiosity shakes up a scoopful of dirt, dusts off the sampling system and investigates a shiny object on the surface of Mars.

Cross-bedding seen in the layers of this Martian rock is evidence of movement of water recorded by waves or ripples of loose sediment the water passed over.

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...

This diagram and the one at PIA16916 illustrate how the Dynamic Albedo of Neutrons (DAN) instrument on NASA's Curiosity Mars rover detects hydrogen in the ground beneath the rover.

This view of terrestrial rocks was taken by a testing twin -- the "life test unit" -- of the Mars Hand Lens Imager (MAHLI) camera on NASA's Mars Science Laboratory.

How samples are delivered and then tested in the Sample Analysis at Mars (SAM) suite on the Mars Curiosity rover. (No audio)

This rectangular version of a self-portrait of NASA's Mars rover Curiosity combines dozens of exposures taken by the rover's Mars Hand Lens Imager (MAHLI) during the 177th Martian day, or sol, of ...

This graphic offers comparisons between the amount of an organic chemical named chlorobenzene detected in the "Cumberland" rock sample and amounts of the same compound in samples from three other M...

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-...
