In Ares Vallis, teardrop mesas extend like pennants behind impact craters, where the raised rocky rims diverted the floods and protected the ground from erosion.

These three views of the Martian moon Phobos were taken by NASA's 2001 Mars Odyssey orbiter using its infrared camera, THEMIS. Each color represents a different temperature range.

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.

Buzz Aldrin, an Apollo 11 astronaut who walked on the moon, makes a holographic appearance in 'Destination: Mars,' a mixed-reality tour of a part of Mars that NASA's Curiosity rover has explored.

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...

Snow falls and ice and frost form on Mars, too. NASA's spacecraft on and orbiting the Red Planet reveal the similarities to and differences from how we experience winter on Earth.  

This image captured by NASA's 2001 Mars Odyssey spacecraft shows 'streamers' of clouds created by katabatic winds at the north polar cap.

This movie shows the Martian moon Phobos as viewed in visible light by NASA's 2001 Mars Odyssey orbiter on April 24, 2019. The apparent motion is due to movement by Odyssey's infrared camera, Therm...

On the southwest edge of the immense volcanic region of Tharsis, lava from its giant volcanoes flowed down to meet the old cratered landscape of Terra Sirenum.

This view combines information from two instruments on NASA's Mars Reconnaissance Orbiter to map color-coded composition over the shape of the ground in a small portion of the Nili Fossae plains re...

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 from NASA's 2001 Mars Odyssey spacecraft shows part of the margin of the north polar cap and the surrounding plains. The layering of the ice is easily visible due to the dust that is dep...

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

A sea of dark dunes, sculpted by the wind into long lines, surrounds the northern polar cap covering an area as big as Texas.

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...

A large mound of sand and dune forms are located on the floor of an unnamed crater south of Rabe Crater in Noachis Terra.

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...

NASA's Mars Odyssey spacecraft passes above a portion of the planet that is rotating into the sunlight in this artist's concept illustration. The spacecraft has been orbiting Mars since October ...

This crater, located in Chryse Planitia, is relatively unmodified, meaning it appears very much like it did when it first formed.
