This image from NASA’s Mars Reconnaissance Orbiter shows spider-like formations at the Martian South Pole. They form when heating from the springtime Sun causes carbon dioxide beneath the surface t...

In this image, taken on June 13, 2019, engineers prepare the starboard legs and wheels — otherwise known as the mobility suspension — for integration onto NASA's Mars 2020 rover.

This HiRISE image shows a mixture of bright and dark units. The bright units have a mineral called sulfate (salty sulfuric acid) that on Earth typically forms in the presence of water as an evapori...

NASA's Mars Exploration Rover Opportunity captured this view after beginning to ascend the northwestern slope of "Solander Point" on the western rim of Endeavour Crater.

This scene from NASA's Mars rover Opportunity shows "Wharton Ridge," which forms part of the southern wall of "Marathon Valley" on the rim of Endeavour Crater. The ridge's name honors the memory of...

The High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter captured these sand ripples and the large dune (at center) on Feb. 9, 2009. Color has been a...

NASA's Mars Exploration Rover Spirit obtained this stereo panorama of the surrounding Martian terrain in Gusev Crater from two positions about 10 meters (33 feet) apart. This is much greater separa...

This sinuous raised ridge is thought to be an inverted stream channel.  These are formerly low-lying streambeds that became elevated because the original depression is filled with materials (such a...

In this image, the second stage of the Black Brant IX sounding rocket separates from the ASPIRE payload. The third and final flight test of the ASPIRE payload was launched from NASA's Wallops Fligh...

An artist's rendering of Mars Pathfinder, which consisted of a lander and the first-ever robotic rover on the surface of the Red Planet. 

This image depicts the demonstration vehicle used to prove that controlled, and sustained flight is feasible in a Martian atmosphere.

NASA's InSight will be the first interplanetary launch from America’s West Coast.

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter acquired this image of the Opportunity rover on the southwest rim of "Santa Maria" crater on New...

Opportunity's wheels dug more than 10 centimeters (4 inches) deep into the soft, sandy material of a wind-shaped ripple in Mars' Meridiani Planum region during the rover's 446th martian day, or sol...

The hills and troughs in this little valley, carved between a ridge and cliffs higher up Mount Sharp, almost look like undulating waves. The Mast Camera (Mastcam) on NASA's Curiosity Mars rover cap...

This is an artist's model of an early Mars - billions of years ago - which may have had oceans and a thicker atmosphere.

Candor Chasma is one of the major canyons within Valles Marineris. The floor of this canyon consist of many layers of light-toned sediments that have been folded and faulted, giving them the wavy a...

Even after the landers and airbags safely bounce to a complete stop on Mars, the challenges of getting to Mars continue. It will take each rover a minimum of nine days to emerge from its lander coc...

Since landing on Mars a year ago, NASA's pair of six-wheeled geologists have been constantly exposed to martian winds and dust.

Stowed in the nose cone of this Delta II rocket, the Mars Exploration Rover blasts off from the Kennedy Space Center in Florida. It's destination: the planet Mars.

This artist's rendition depicts NASA's Mars 2020 rover studying rocks with its robotic arm.  

Interact with this 3D model of Deimos.

This bird's-eye view combines a self-portrait of the spacecraft deck and a panoramic mosaic of the Martian surface as viewed by the Spirit rover.

NASA discussed the status of its Mars Exploration Rover (MER) Opportunity in a media briefing at 11 a.m. PST (2 p.m. EST) Wednesday, Feb. 13, from the agency’s Jet Propulsion Laboratory (JPL) in Pa...

NASA's Mars Exploration Rover Opportunity has been working on Mars since landing inside Eagle Crater on Jan. 25, 2004 (Universal Time; evening of Jan. 24, Pacific Standard Time).
