Artist concept of Mars Reconnaissance Orbiter

The white speck is NASA’s Perseverance rover in the “South Séítah” area of Mars’ Jezero Crater.

A rippled patch of sand in Becquerel Crater on Mars moved about two meters (about two yards) between November 24, 2006 and September 5, 2010, as observed in these images taken by NASA's Mars Reconn...

This is an image of Gusev Crater taken by the Mars Reconnaissance Orbiter HiRISE camera and is one of the potential landing sites for the Mars 2020 rover.

These images show a 256 x 256 pixel patch of sky at the range to the comet of 8 million miles and when the solar phase angle is 47 degrees.

Valleys much younger than well-known ancient valley networks on Mars are evident near the informally named "Heart Lake" on Mars. This map presents color-coded topographical information overlaid ont...

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...

This image from NASA's Mars Reconnaissance Orbiter shows Aram Chaos, an ancient impact crater that lies within in the Southern Highlands of Mars. Uplifted blocks are composed largely of the iron-ox...

This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows gullies near the edge of Hale crater on southern Mars. The view covers an ...

This image taken by NASA’s Mars Reconnaissance Orbiter shows ice sheets at Mars’ south pole. The spacecraft detected clays nearby this ice; scientists have proposed such clays are the source of rad...

This image covers plains near Aureum Chaos.

This image acquired on October 1, 2020 by NASAs Mars Reconnaissance Orbiter, shows several craters in Arabia Terra filled with layered rock.

The material in the upper portion of this image, perhaps hardened volcanic ash deposits, is being eroded into parallel long, thin ridges called yardangs by the strong prevailing winds.

The Mars Reconnaissance Orbiter has seen many places on the planet. One of the most interesting is one of the great canyon systems on Mars.

Cydonia Labyrinthus is a complex of intersecting valleys that form a polygonal fractured terrain.

Shown here is a stereo pair of a well-preserved impact crater about 6 or 7 kilometers wide from rim to rim.

The large impact crater known as Stickney is the largest crater on the Martian moon Phobos.

This picture of a crater resembling a "happy face" was taken by the Mars Reconnaissance Orbiter's Context Camera. The unnamed crater is almost 2 miles (about 3 kilometers) across That's a BIG smile!

NASA's Curiosity rover and its parachute were spotted by NASA's Mars Reconnaissance Orbiter as Curiosity descended to the surface on Aug. 5 PDT (Aug. 6 EDT).

This Mars map shows variations in thickness of the planet's crust, the relatively thin surface layer overlying the mantle of the planet. It shows unprecedented detail derived from new mapping of va...

Researchers have found deposits of impact glass preserved in Martian craters, including Alga Crater, shown here.

This map shows the route driven by NASA's Mars rover Curiosity through the 29th Martian day, or sol, of the rover's mission on Mars (Sept. 4, 2012).

Mars Reconnaissance Orbiter Project Manager Jim Graf shakes the hand of Andrew Dantzler, Director of NASA's Solar System Division, after a successful orbit insertion on March 10, 2006. Fuk Li, Dire...

This color view of the parachute and back shell that helped deliver NASA's Curiosity rover to the surface of the Red Planet was taken by the High-Resolution Imaging Science Experiment (HiRISE) came...

This image acquired on December 9, 2018 by NASAs Mars Reconnaissance Orbiter, shows Athabasca Valles with lava flows originating from Elysium Mons to the northwest.

Sand dunes such as those seen in this image have been observed to creep slowly across the surface of Mars through the action of the wind.
