Common to the northern plains of Mars are rock and boulder strewn landscapes otherwise devoid of major features except a few impact craters. This image in the Cydnus Rupes region of northern Utopia...

A small channel cuts across the floor of a gigantic 1100-mile (1780-kilometer)-long set of flood-carved channels in a region on Mars called "Kasei Valles."

This view of a portion of the Eridania region of Mars shows blocks of deep-basin deposits that have been surrounded and partially buried by younger volcanic deposits. The image was taken by the Con...

This image from NASA's Mars Reconnaissance Orbiter shows many new ice blocks compared to earlier images in 2006. One of the most actively changing areas on Mars are the steep edges of the North Pol...

NASA's Opportunity Mars rover, working on Mars since January 2004, passed marathon distance in total driving on March 24, 2015. This map shows the rover's entire traverse from landing to that point.

This April 6, 2014, image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows numerous landslides in the vicinity of where an impact crat...

Mars Reconnaissance Orbiter Project Manager Jim Graf hugs Jet Propulsion Laboratory Director Dr. Charles Elachi after a successful orbit insertion on March 10, 2006.

This set of images from cameras on NASA's Mars Reconnaissance Orbiter documents the appearance of a new cluster of impact craters on Mars.

This image acquired on February 7, 2019 by NASAs Mars Reconnaissance Orbiter, shows Mawrth Vallis, a place on Mars that has fascinated scientists because of the clays and other hydrated minerals de...

Part of the canyon floor and wall rock in southwestern Melas Chasma on Mars meanders in a pattern resembling a dragon.

This image shows an outcrop of the south polar layered deposits (SPLD). The SPLD consist of layers of ice and admixed dust and make up the bulk of the dome-shaped Planum Australe.

This close-up image of a dust storm on Mars was acquired by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter on Nov. 7, 2007

A path resembling a dotted line from the upper left to middle right of this image is the track left by an irregularly shaped, oblong boulder as it tumbled down a slope on Mars before coming to rest...

This map shows the route driven by NASA's Mars rover Curiosity through the 43rd Martian day, or sol, of the rover's mission on Mars (Sept. 19, 2012).

NASA’s Ingenuity Mars Helicopter’s fourth flight path is superimposed here atop terrain imaged by the HiRISE camera aboard the agency’s Mars Reconnaissance Orbiter.

This map shows the location of "Cumberland," the second rock-drilling target for NASA's Mars rover Curiosity, in relation to the rover's first drilling target, "John Klein," within the southwestern...

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

Back-and-forth blinking of this two-image animation shows movement of a sand dune on Mars. The images are part of a study published by Nature on May 9, 2012, reporting movement of Martian sand dune...

Impact cratering and erosion combine to reveal the composition of the Martian underground by exposing materials from the subsurface.

This image of Santa Maria Crater was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on Mars Reconnaissance Orbiter.

This image acquired on October 5, 2018 by NASAs Mars Reconnaissance Orbiter, shows a new impact crater that formed between July and September 2018.
