Artist's concept of future humans on Mars.

This lunar-like scene occurs along the southeastern rim of the Isidis Planitia basin. The Isidis basin is an ancient impact crater some 1200 km across that is found along the boundary separating th...

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

The floor of this unnamed crater in Aonia Terra has been filled with multiple layers of material.

Five decades of successful NASA missions to the Red Planet, 1965-2015.

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

Echus Chasma forms the boundary between the Tharsis volcanoes to the west and Lunae Planum to the east. This region is one of both tectonically fractured rocks (top of image) and volcanic flows (mi...

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...

Western flank of Elysium Mons.

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.

Fans and ribbons of dark sand dunes creep across the floor of Bunge Crater in response to winds blowing from the direction at the top of the picture.

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 unnamed channel is located in Xanthe 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...

A new map of Mars' gravity made with three NASA spacecraft is the most detailed to date, providing a revealing glimpse into the hidden interior of the Red Planet. Satellites always orbit a planet's...

Large fractures have formed 'steps' in this region of Tempe Terra.

The annotated area of Mars in this illustration holds near-surface water ice that would be easily accessible for astronauts to dig up. The water ice was identified as part of a map using data from ...

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

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.

NASA’s 2001 Mars Odyssey orbiter is depicted in this illustration.

This THEMIS visible image shows a close-up view of the ridged plains in Hesperia Planum. This region is the classic locality for martian surfaces that formed in the "middle ages" of martian history.

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.

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...

This false-color map shows the area within Gale Crater on Mars, where NASA's Curiosity rover landed on Aug. 5, 2012 PDT (Aug. 6, 2012 EDT) and the location where Curiosity collected its first drill...

Part of a multispectral THEMIS infrared image of Nili Patera caldera on Syrtis Major has been superimposed on a high-resolution THEMIS visual image.

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...
