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 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 130th Martian day, or sol, (De...

The Mast Camera (Mastcam) on NASA's Mars rover Curiosity showed researchers interesting internal color in this rock called "Sutton_Inlier," which was broken by the rover driving over it.

A group of journalists take part in a field trip to learn about the clues hidden in the rock layers with Curiosity Project Scientist, John Grotzinger.

This image taken by the Mast Camera (MastCam) on NASA's Curiosity rover highlights the interesting geology of Mount Sharp, a mountain inside Gale Crater, where the rover landed.

This image shows engineers' refinements of where NASA's Curiosity rover will enter the atmosphere of Mars on Aug. 5 PDT (Aug. 6 EDT).

This view from the Mast Camera (Mastcam) on NASA's Mars rover Curiosity shows an example of cross-bedding that results from water passing over a loose bed of sediment.

This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows a mesa within the "Murray Buttes" area on Mars showing a complex fracture pattern (black arrow) protrudi...

The team developing NASA's Mars Science Laboratory calls this test rover "Scarecrow" because the vehicle does not include a computer brain. Mobility engineers use this test rover to evaluate mobili...

This image from the right Mast Camera (Mastcam) of NASA's Mars rover Curiosity shows a scoop full of sand and dust lifted by the rover's first use of the scoop on its robotic arm.

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

This 360-degree vista was acquired on Aug. 5, 2016, by the Mastcam on NASA's Curiosity Mars rover as the rover neared features called "Murray Buttes" on lower Mount Sharp. The dark, flat-topped mes...

The Sample Analysis at Mars (SAM) instrument for NASA's Mars Science Laboratory mission will study chemistry of rocks, soil and air as the mission's rover, Curiosity, investigates Gale Crater on Mars.

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...

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.

This is a view of the third (left) and fourth (right) trenches made by the 1.6-inch-wide (4-centimeter-wide) scoop on NASA's Mars rover Curiosity in October 2012.
