This global map of Mars was acquired on Aug. 4, 2012, by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter.

This diagram shows how materials analyzed by ChemCam during the first 100 Martian days of the mission (Aug. 5, 2012, to Nov. 16, 2013) differed with regard to hydrogen content (horizontal axis) and...

On this image of the rock target "Knorr," color coding maps the amount of mineral hydration indicated by a ratio of near-infrared reflectance intensities measured by the Mast Camera (Mastcam) on NA...

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 long journey to Mars through the harsh environment of space confronts the Curiosity navigation team with a long list of challenges to get the spacecraft safely to its destination.

This animation shows how the Mars Hand Lens Imager (MAHLI) camera at the end of the arm of NASA's Mars rover Curiosity was positioned for taking multiple images that were later combined into a self...

This animation depicts movements of the robotic arm of NASA's Mars rover Curiosity as commanded for Aug. 20, 2012, the first time the arm was used on Mars. The animation is derived from visualizati...

The Rover Environmental Monitoring Station (REMS) on NASA's Curiosity Mars rover includes temperature and humidity sensors mounted on the rover's mast. One of the REMS booms extends to the left fro...

The team responsible for the Sample Analysis at Mars (SAM) instrument suite on NASA's Curiosity rover has made the first definitive detection of organic molecules at Mars.

This 360-degree panorama was acquired on Sept. 4, 2016, by the Mast Camera on NASA's Curiosity Mars rover while the rover was in a scenic area called "Murray Buttes" on lower Mount Sharp. The flat-...

Musician will.i.am addresses a crowd of students at JPL during an event celebrating the first time in history that a recorded song has been beamed back to Earth from another planet.

NASA's Curiosity rover found evidence for an ancient, flowing stream on Mars at a few sites, including the rock outcrop pictured here, which the science team has named "Hottah" after Hottah Lake in...

This September 2016 self-portrait of NASA's Curiosity Mars rover shows the vehicle at the "Quela" drilling location in the scenic "Murray Buttes" area on lower Mount Sharp. The panorama was stitche...

This computer-generated view based on multiple orbital observations shows Mars' Gale crater as if seen from an aircraft north of the crater.

NASA's Curiosity Mars rover caught its own shadow in this image taken just after completing a drive of 329 feet (100.3 meters) on the 547th Martian day, or sol, of the rover's work on Mars (Feb. 18...

At the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, technicians, using an overhead crane, separate the two components of the aeroshell, an element of NASA's Mars ...

As the Sample Analysis at Mars (SAM) suite of instruments on NASA's Curiosity Mars rover heats a sample, gases are released (or "evolved") from the sample and can be identified using SAM's quadrupo...

Large Parachute for NASA's Mars Science Laboratory

The Martian outcrop where pale rock meets darker overlying rock near the middle of this view is an example of a geological contact.

This March 25, 2014, view from the Mastcam on NASA's Curiosity Mars rover looks southward at the Kimberley waypoint. In the foreground, multiple sandstone beds show systematic inclination to the so...

This view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover covers an area in "Bridger Basin" that includes the locations where the rover drilled a target called "Big Sky" on the missio...

This stereo mosaic of images from the Navigation Camera (Navcam) on NASA's Mars rover Curiosity shows the terrain to the west from the rover's position on the 528th Martian day, or sol, of the miss...

This image produced from software used for planning drives of NASA's Mars rover Curiosity depicts the location and size of the rover when it was driven into position for drilling into rock target "...
