The Sample Analysis at Mars (SAM) instrument, largest of the 10 science instruments for NASA's Mars Science Laboratory mission, will examine samples of Martian rocks, soil and atmosphere for inform...

This view of a Martian rock called "Rocknest 3" combines four images taken by the right-eye camera of the Mast Camera (Mastcam) instrument, which has a telephoto, 100-millimeter-focal-length lens.

Members of NASA's Curiosity Mars rover mission team photographed themselves on March 20, 2020, the first day the entire mission team worked remotely from home. 

The dark band in the lower portion of this Martian scene is part of the "Bagnold Dunes" dune field lining the northwestern edge of Mount Sharp. The scene combines multiple images taken with the Mas...

NASA's Curiosity rover takes a short breather on her trek to Glenelg to check out her arm instruments.

This 360-degree panorama shows evidence of a successful first test drive for NASA's Curiosity rover.

This map traces where NASA's Mars rover Curiosity drove between landing at a site subsequently named "Bradbury Landing," and the position reached during the mission's 123rd Martian day, or sol, (De...

Many members of NASA's Mars Science Laboratory Project, which operates the Curiosity rover on Mars, gathered for this 2016 team photo with a test rover in the "Mars Yard" at NASA's Jet Propulsion L...

Processes in Mars' surface material can explain why particular xenon (Xe) and krypton (Kr) isotopes are more abundant in the Martian atmosphere than expected, as measured by NASA's Curiosity rover....

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...

Engineers who designed the entry, descent and landing system for NASA's Mars rover Curiosity candidly talk about the new landing system, and describe the challenges of Curiosity's final moments bef...

This patch of Martian bedrock, about 2 feet (70 centimeters) across, is finely layered rock with some pea-size inclusions. It lies near the lowest point of the "Pahrump Hills" outcrop, which forms ...

This image taken by NASA's Curiosity shows what lies ahead for the rover -- its main science target, Mount Sharp.

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

NASA's Curiosity Mars rover used its Navigation Camera (Navcam) to capture this view on April 11, 2015, during the 952nd Martian day, or sol of the rover's work on Mars. The image appears three-dim...

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

This illustration shows the locations and interactions of volatiles on Mars. Volatiles are molecules that readily evaporate, converting to their gaseous form, such as water and carbon dioxide.

NASA's Mars Science Laboratory spacecraft has been fully stacked for flight in this photograph from inside the Payload Hazardous Servicing Facility at NASA Kennedy Space Center, Fla., in October 2011.

​ NASA's Curiosity rover used an instrument called SAM (Sample Analysis at Mars) to detect seasonal changes in atmospheric methane in Gale Crater. The methane signal has been observed for nearly...

The Chemistry and Camera (ChemCam) instrument on NASA's Curiosity Mars rover fired its laser 50 times at its onboard graphite target during the 27th Martian day, or sol, of the rover's work on Mars...

A "scarecrow" rover at NASA's JPL drives over a sensor while testing a new driving algorithm. Engineers created the algorithm to reduce wheel wear on the Mars Curiosity rover.

This image shows inclined beds characteristic of delta deposits where a stream entered a lake, but at a higher elevation and farther south than other delta deposits north of Mount Sharp. This sugge...

NASA's Curiosity rover and its rocket-powered descent vehicle pose for a portrait at JPL's Spacecraft Assembly Facility. During a nearly two-year prime mission after landing on Mars, the rover will...

This global map of Mars was acquired on July 31, 2012, by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter.

An area inside Holden crater was considered as a landing site for NASA's Mars Science Laboratory mission.
