Engineers work on Opportunity (in its cruise configuration) in a cleanroom at Kennedy Space Center. A very important part of planetary protection is keeping contaminants from humans from riding abo...

This 360-degree image shows a complete, full-resolution panorama around NASA's Curiosity rover, taken by the Navigation cameras.

This view of the head of the remote sensing mast on the Mars Science Laboratory mission's rover, Curiosity, shows seven of the 17 cameras on the rover.

This graphic maps the first 14 sites where NASA's Curiosity Mars rover collected rock or soil samples for analysis using the rover's onboard laboratory. It also presents images of the drilled holes...

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.

On June 24, 2014, NASA's Curiosity rover completes her first Martian year (687 Earth days).

The total distance driven by NASA's Mars rover Curiosity passed the one-mile mark a few days before the first anniversary of the rover's landing on Mars.

This is the first image taken by NASA's Curiosity rover, which landed on Mars the evening of Aug. 5 PDT (morning of 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 map shows where NASA's Mars rover Curiosity landed in August 2012 at "Bradbury Landing"; the area where the rover worked from November 2012 through May 2013 at and near the "John Klein" target...

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 ...

This view shows grains of sand where NASA's Curiosity Mars rover was driven into a shallow sand sheet near a large dune. The scene covers an area 1.3 inches wide, imaged by Curiosity's Mars Hand Le...

This set of images compares test images taken by four cameras on NASA's Curiosity rover at NASA's Jet Propulsion Laboratory before launch.

The first examinations of Martian soil by the Sample Analysis at Mars, or SAM, instrument on NASA's Mars Curiosity rover show no definitive detection of Martian organic molecules at this point.

Amanda Steffy and Rob Sullivan help shape a course of sand ripples for the Scarecrow rover to drive over. This test was done in the Dumont Dunes in California's Mojave Desert, near Death Valley.

This image shows the underside of a grey F/A-18 jet with dark stripes flying against a blue sky from quite a distance away. Underneath the jet is a pod carrying sensors that measure the jet's tempe...

This pair of images from the Mast Camera on NASA's Curiosity rover shows the upper portion of a wind-blown deposit dubbed "Rocknest."

This graphic shows the ongoing contributions of NASA’s rovers and orbiters during a Martian dust storm that began on May 30, 2018.

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 view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows a swath of bedrock called "Alexander Hills," which the rover approached for close-up inspection of selected targets. It...
