Artist concept of Glaciers on Mars

This image from NASA's Mars Reconnaissance Orbiter (MRO) shows the permanent polar cap of Mars, encircled by sand dunes and looking like pulled threads. These dunes march across a fabric of pattern...

This image acquired on October 28, 2018 by NASAs Mars Reconnaissance Orbiter, shows that gullies probably formed along the bouldery layers in the upper slopes of this unnamed crater.

The MRO Context Camera, CTX, at Malin Space Science Systems in 2004, before it was delivered and mounted on the spacecraft.

This movie sequence of images from NASA's Mars Reconnaissance Orbiter (MRO) shows comet C/2013 A1 Siding Spring before and after its close pass by Mars in October 2014. False color enhances subtle ...

NASA's Curiosity Mars rover and its tracks are visible in this view combining information from three observations by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Re...

Women working in science, technology, engineering and mathematics at NASA's Jet Propulsion Laboratory pose for a photo in mission control in honor of Women in Science Day.

This fresh crater is located in the northern mid-latitudes. It is designated as fresh because of its very sharp rim.

NASA's InSight spacecraft and its recently deployed Wind and Thermal Shield were imaged on Feb. 4 by the HiRISE camera aboard NASA's Mars Reconnaissance Orbiter.

An oblique, northward-looking view based on stereo orbital imaging, shows the location of Opportunity on its journey from Cape York to Solander Point when HiRISE took the new color image.

This photograph from Shiprock in northwestern New Mexico shows a ridge roughly 30 feet (about 10 meters) tall that formed from lava filling an underground fracture then resisting erosion better tha...

With the spacecraft safely captured into orbit, the Mars Reconnaissance Orbiter team transitions to the next critical phase -- aerobraking. Learn how engineers slow the spacecraft and precisely sha...

Terrain in Vastitas Borealis Region.

The High-Resolution Imaging Science Experiment (Hi-RISE) camera aboard NASA's Mars Reconnaissance Orbiter captured this avalanche plunging down a 1,640-foot-tall (500-meter-tall) cliff on May 29, 2...

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter caught this view of NASA's Mars Exploration Rover Opportunity on Feb. 14, 2014.

This vertically exaggerated view shows scalloped depressions in a part of Mars where such textures prompted researchers to check for buried ice, using ground-penetrating radar aboard NASA's Mars Re...

Intra-Crater Structure in NW Hellas Basin, Mars

NASA’s Perseverance Mars rover and Ingenuity helicopter were spotted on the surface of the Red Planet in this black-and-white image captured Feb. 26, 2022, by the HiRISE camera aboard NASA’s Mars R...

Lighter colors represent higher elevation in this image of Jezero Crater on Mars, the landing site for NASA's Mars 2020 mission. The oval indicates the landing ellipse, where the rover will be touc...

This is a small volcano superposed on the flanks of a larger one of the Cerberus Tholi. 

This May 2015 image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows a location on Mars associated with the best-selling novel and Hollywood movie, "The Martian." It is in a regio...

The two largest quakes detected by NASA's InSight appear to have originated in a region of Mars called Cerberus Fossae.

This artist's animation shows how orbiters over Mars will monitor the landing of NASA's Curiosity rover. (No audio)

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).

The north polar layered deposits, and the bright ice cap that covers them, are very young (by geologic standards) features.

This image taken on May 19, 2010, shows an impact crater that had not existed when the same location on Mars was previously observed in March 2008.
