This full-resolution color image from NASA's Curiosity Rover shows the gravel-covered surface of Mars. It was taken by the Mars Descent Imager (MARDI) several minutes after Curiosity touched down o...

Lucus Planum is a part of the enigmatic Medusa Fossae Formation, a broad, soft, and easily eroded deposit. Here this deposit is thin and considerably rougher than elsewhere, implying that it is hea...

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

This pair of images taken one day apart by the Mars Color Imager (MARCI) weather camera on NASA's Mars Reconnaissance Orbiter reveals when an asteroid impact made the scar seen in the right-hand im...

Three pairs of before and after images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter illustrate movement of ripples on dark sand dunes in...

This image shows the quadrangle where NASA's Curiosity rover landed, now called Yellowknife.

Icy Layers and Climate Fluctuations near the Martian North Pole

This map shows the route driven by NASA's Curiosity Mars rover from the location where it landed in August 2012 to its location in mid-November 2015, approaching examples of dunes in the "Bagnold D...

By analyzing radar images like the one at top of this montage, scientists discovered evidence for a past ice age in the northern polar ice cap of Mars.

Explanation on how CRISM hyperspectral images are used to understand the history and formation of Valles Marineris, one of the largest canyons in the solar system, and how the data is used to unrav...

This image covers part of the floor of a large ancient impact crater, near the western rim.

This is a close-up of the area in the vicinity of the Pathfinder landing site. Major features are named. The white box outlines the area of the image, where hardware is seen.

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...

This image shows part of the floor of an impact crater on the northern rim of the giant Hellas Basin.

In February 2015, NASA's Mars Exploration Rover Opportunity is approaching a cumulative driving distance on Mars equal to the length of a marathon race. This map shows the rover's position relative...

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

Layers in the lower portion of two neighboring buttes within the Noctis Labyrinthus formation on Mars are visible in this image from the High Resolution Imaging Science Experiment (HiRISE) camera o...

These two images show Shallow Radar (SHARAD) instrument data from two tracks in a part of Mars' Utopia Planitia region where the orbiting, ground-penetrating radar on NASA's Mars Reconnaissance Orb...

This movie clip shows a global map of Mars with atmospheric changes from Feb. 18, 2017, through March 6, 2017, a period when two regional-scale dust storms appeared. It combines hundreds of images ...

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).
