Artist's concept of future humans on Mars.

A false-color mosaic focuses on one junction in Noctis Labyrinthus where Mars canyons meet to form a depression 4,000 meters (13,000 feet) deep.

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...

This image shows a 90-mile-wide portion of the giant Valles Marineris canyon system. Landslide debris and gullies in the canyon walls on Mars can be seen at 100 meters (330 feet) per pixel.

This map of Mars indicates locations of new craters that have excavated ice (blue) and those that have not (red). The underlying map is based on the brightness, or albedo, of the Martian surface.

Getting to Mars is difficult enough -- staying there is even more challenging. Odyssey met up with Mars on October 24 02:26 UTC (October 23: 7:26 p.m. PDT/10:26 p.m.EDT).

Sand-laden jets shoot into the polar sky in this view by noted space artist Ron Miller.

This graphic shows the ongoing contributions of NASA’s rovers and orbiters during a Martian dust storm that began on May 30, 2018.

Just as on Earth, volcanism and tectonism are found together on Mars. Here is an example: the ridges and fractures of Claritas Fossae are affecting or perhaps hosting the volcanic flows of Solis Pl...

This computer-generated view based on multiple orbital observations shows Mars' Gale crater as if seen from an aircraft north of the crater.

Valles Marineris, the "Grand Canyon of Mars," sprawls wide enough to reach from Los Angeles to nearly New York City, if it were located on Earth. The red outline box shows the location of a second,...

These are two views of the same observation of the Martian moon Phobos taken in both infrared and visible light by NASA's 2001 Mars Odyssey orbiter using its THEMIS camera. The image was taken on A...

Researchers estimating the amount of carbon held in the ground at the largest known carbonate-containing deposit on Mars utilized data from three different NASA Mars orbiters.

This color-coded map indicates the depth to icy layers at a site in southern Mars. The dense, icy layer retains heat better than the looser soil above it, so where the icy layer is closer to the su...

This computer-generated view based on multiple orbital observations shows Mars' Gale crater as if seen from an aircraft north of the crater.

The artist's animation depicts how NASA's Curiosity rover will communicate with Earth during landing. As the rover descends to Mars, it will send out basic radio-frequency tones that go directly to...

A dust storm continues to envelop the Red Planet and Curiosity’s labs are back in action.

This region of Terra Sabaea contains areas with high densities of small craters.

Colors in this image of the Martian moon Phobos indicate a range of surface temperatures detected by observing the moon on Sept. 29, 2017, with the Thermal Emission Imaging System (THEMIS) camera o...

This image combines two products from the first pointing at the Martian moon Phobos by the THEMIS camera on NASA's Mars Odyssey orbiter, on Sept. 29, 2017. Surface-temperature information from obse...

Fly Through Mariner Valley

At 11:02 a.m. EDT on April 7, 2001, crowds watch a Boeing Delta II rocket lift off from Cape Canaveral Air Force Station, Florida, carrying NASA's 2001 Mars Odyssey spacecraft into space on its sev...

Around 200 kilometers long, Ravi Vallis was born in a flood of water from Aromatum Chaos.
