The sequence of six images in this animation shows sunspots as viewed by NASA's Curiosity Mars rover from April 4 to April 15, 2015. From Mars, the rover was in position to see the opposite side of...

This version of a self-portrait of NASA's Curiosity Mars rover at a drilling site called "Buckskin" is presented as a stereographic projection, which shows the horizon as a circle. The MAHLI camera...

Mars scientists used images from the Mars Exploration Rovers to help them with their recent simulation 'games' for the Mars Science Laboratory rover. This image from the Spirit rover was used by th...

This plot shows the first-ever look at the deuterium to hydrogen ratio measured from the surface of Mars, as detected by the Sample Analysis at Mars instrument, or SAM, on NASA's Curiosity rover.

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...

This image from the Mars Hand Lens Imager (MAHLI) on NASA's Mars rover Curiosity shows details of rock texture and color in an area where the rover's Dust Removal Tool (DRT) brushed away dust 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.

NASA's Curiosity finds crystals, Opportunity celebrates her 5,000th day on Mars and the MarCO smallsats get solar arrays.

This map shows the path on Mars of NASA's Curiosity rover toward Glenelg, an area where three terrains of scientific interest converge.

This image from the Mars Hand Lens Imager (MAHLI) camera on NASA's Curiosity Mars rover shows the first sample-collection hole drilled in Mount Sharp, the layered mountain that is the science desti...

This map shows the route driven by NASA's Mars rover Curiosity through the 29th Martian day, or sol, of the rover's mission on Mars (Sept. 4, 2012).

JPL researchers Jessica Creamer, Fernanda Mora and Peter Willis (left to right) pose with the Chemical Laptop, a device designed to detect amino acids and fatty acids. At left is a near-identical c...

A close-up view of a microchip with 1.2 million names that will be placed aboard NASA's Mars Curiosity Rover. Engineers etched the names onto a silicon wafer or microchip. They used an electron be...

The main map here shows the assortment of landforms near the location of NASA's Curiosity Mars rover as the rover's second anniversary of landing on Mars nears.

In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, technicians guide the backshell as it is lowered over NASA's Mars Science Laboratory (MSL) rover, Curiosity, f...

This map shows in red the route driven by NASA's Curiosity Mars rover from the "Bradbury Landing" location where it landed in August 2012 to nearly the completion of its first Martian year. The whi...

Rhythmic patterns of sedimentary layering in Danielson Crater on Mars result from periodic changes in climate related to changes in tilt of the planet.

This 360-degree panorama shows the "Marias Pass" area, at center, and part of the slope that NASA's Curiosity Mars rover climbed to get there, at right.

This pair of images from the Mars Hand Lens Imager (MAHLI) on NASA's Mars rover Curiosity shows the rock target "Cumberland" before and after Curiosity drilled into it to collect a sample for analy...

One type of feature of scientific interest on the mountain inside Gale crater is exposure of cemented fractures, evidence that groundwater once reached to at least that height of the mountain.

This image from the Navigation Camera on NASA's Curiosity Mars rover shows a sandstone slab on which the rover team has selected a target, "Windjana," for close-up examination.
