This illustration shows the instruments and subsystems of the Sample Analysis at Mars (SAM) suite on the Curiosity Rover of NASA's Mars Science Laboratory Project.

A chapter of the layered geological history of Mars is laid bare in this postcard from NASA's Curiosity rover. The image shows the base of Mount Sharp, the rover's eventual science destination.

This view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows a network of two-tone mineral veins at an area called "Garden City" on lower Mount Sharp.

The first demonstration of NASA's MAVEN Mars orbiter's capability to relay data from a Mars surface mission, on Nov. 6, 2014, included this and other images from NASA's Curiosity Mars rover. The im...

Students decide what they want to learn from a robotic mission to Mars.

This false-color map shows the area within Gale Crater on Mars, where NASA's Curiosity rover landed on Aug. 5, 2012 PDT (Aug. 6, 2012 EDT).

NASA's Curiosity Mars rover used its Navigation Camera (Navcam) to capture this view partway back down a slope it climbed toward "Marias Pass" on lower Mount Sharp. The image was taken May 22, 2015...

This sequence of images shows a blast zone where the sky crane from NASA's Curiosity rover mission hit the ground after setting the rover down in August 2012, and how that dark scar's appearance ch...

This map shows where NASA's Mars rover Curiosity has driven since landing at a site subsequently named "Bradbury Landing," and traveling to an overlook position near beside "Point Lake," in drives ...

Technicians at the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, put the instrument mast and science boom on NASA's Mars Science Laboratory (MSL) rover, known as C...

Close-up of Curiosity's Landing Region

Curiosity's analyzed rock sample proves ancient Mars could have supported living microbes.

NASA and Microsoft have teamed up to create "Destination: Mars," a guided tour of Mars using the same Hololens technology that helps scientists plan the Curiosity rover's activities.

This video, taken by one of the Navigation Cameras, or Navcams, on NASA's Curiosity Mars rover, shows the rover's robotic arm as it rotates to take a selfie. A camera at the end of the arm captured...

The Mast Camera (Mastcam) on NASA's Mars rover Curiosity showed researchers interesting color and patterns in this unnamed rock imaged during the 27th Martian day, or sol, of the rover's work on Ma...

President Obama phoned the team at JPL on Monday, Aug. 13, to congratulate them on the successful landing of Curiosity. "It's inspiring to all of us. Photographs that are coming back are going to b...

NASA's Mars rover Curiosity extended its robotic arm on Aug. 20, 2012, for the first time on Mars and used its Navigation Camera (Navcam) to capture this view of the extended arm.

This graphic illustrates how dimensions of clay minerals' crystal structure are affected by which ions are present in the mineral. The CheMin instrument on NASA's Curiosity Mars rover identified di...

NASA's Mars rovers keep getting bigger. This photo provides a comparison of the wheel sizes for three generations of them.

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...
