Planum Boreum crater

NASA's 2001 Mars Odyssey orbiter arrived at Mars on Oct. 24, 2001.

Sixteen seventh-graders at Evergreen Middle School in Cottonwood, Calif., found the Martian pit feature at the center of the superimposed red square in this image while participating in a program t...

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...

Six views of the Martian moon Phobos captured by NASA's Odyssey orbiter as of March 2020. The orbiter's THEMIS camera is used to measure temperature variations that suggest what kind of material th...

Color coding in this map of a far-northern site on Mars indicates the change in nighttime ground-surface temperature between summer and fall. This site, like most of high-latitude Mars, has water i...

Mars is experiencing large regional dust storms over its northern hemisphere during the past week.

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.

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.

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.

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.  

Wind shadow and real shadow combine to give a striking image of a comet.

How do you converse with a robot nearly one hundred million miles away? In this video, Odyssey team members describe communications with the 2001 Mars Odyssey spacecraft using the antennas of the D...

A small impact crater on Mars named Gratteri, 4.3 miles (6.9 km) wide, lies at the center of large dark streaks.

This image shows the context for orbital observations of exposed rocks that had been buried an estimated 5 kilometers (3 miles) deep on Mars.

This pair of maps indicates locations of confirmed sites of recurrent slope linea on Mars, with respect to elevation (upper map) and surface brightness, or albedo (lower map).

This image from NASA's Mars Odyssey shows ice-rich clouds over the summit of Arsia Mons.

This map shows unprecedented detail of local variations in Mars' gravitational pull on orbiters. The gravitational mapping has been applied to map variations in the thickness of the planet's crust ...

The dunes and dust devil tracks in this VIS image are located on the plains of Planum Chronium.

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...

NASA's Mars Odyssey spacecraft passes above Mars' south pole in this artist's concept illustration. The spacecraft has been orbiting Mars since October 24, 2001.

This image of a crater in Acidalia Planitia was acquired March 8, 2003, during northern summer.

Bacolor Crater is a magnificent impact feature about 20 kilometers (12 miles) wide.
