Artist concept of Glaciers on Mars

This map shows the thickness of the north polar layered deposits on Mars as measured by the Shallow Radar instrument on NASA's Mars Reconnaissance Orbiter.

In this HiRISE image taken within Capri Chasma, TES also detected the same crystalline gray hematite like that found at Meridiani Planum.

This animation shows NASA's Mars Reconnaissance Orbiter flying over NASA's Curiosity (shown in pink) as the rover lands on the Red Planet. The video is slowed down as the orbiter approaches the lan...

A large dust storm on Mars, nearly twice the size of the United States, covered the southern hemisphere of the Red Planet in early January 2022, leading to some of NASA’s explorers on the surface h...

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

This inner slope of a Martian crater has several of the seasonal dark streaks called "recurrent slope lineae," or RSL, that a November 2017 report interprets as granular flows, rather than darkenin...

This crater, formed in 2008, exposes shallow, clean ice that is not uncommon in the middle-to-high latitudes on Mars.

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.

This is an image of a central pit of an impact crater in the Martian ancient highlands.

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...

The South Polar residual cap (the part that lasts through the summer) is composed of carbon dioxide ice.

This April 6, 2014, image from the Context Camera on NASA's Mars Reconnaissance Orbiter was taken as a follow-up to discovery of a possible 2012 impact scar in images from the orbiter's Mars Color ...

Phobos from 6,800 Kilometers

Eberswalde Crater was one of the four final landing sites considered for the MSL rover. A channel leads into the crater and the lithified remains of a delta, a fan-like feature formed when sediment...

This crater has gullies on its southwest-facing walls and rim, as well as and what appears to be two separate instances of lobate (ear-shaped) material associated to its interior gullies.

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).

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...

Mars's seasonal polar caps are composed primarily of carbon-dioxide frost.

This observation shows erosional features on light-toned rocks in Aram Chaos, a crater near the equator of Mars that has been nearly filled with sedimentary rocks.

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.

Stokes Crater, pictured here, is one of at least nine craters in the northern lowlands of Mars with exposures of hydrated minerals detected from orbit, according to a June 25, 2010, report.

This image shows the landing site of NASA's Curiosity rover and destinations scientists want to investigate.

Polar Layered Deposits Stratigraphy Near Chasma Australe

This image acquired on September 18, 2018 by NASAs Mars Reconnaissance Orbiter, shows araneiform terrain (colloquially: spider-like terrain) located in the south polar region of Mars.

This map shows where NASA's Mars rover Curiosity has driven since landing at a site subsequently named "Bradbury Landing," and traveling to an overlook position near beside "Point Lake," in drives ...
