Dunes in Aonia Terra

This unusual view of the horizon of Mars was captured by NASA’s Odyssey orbiter using its THEMIS camera, in an operation that took engineers three months to plan. It’s taken from about 250 miles ab...

No NASA Mars orbiter has been in a position to observe morning daylight on Mars since the twin Viking orbiters of the 1970s.

NASA’s Mars Odyssey orbiter captured the first-ever views of Mars that showcase the curving horizon and layers of atmosphere, similar to what an astronaut sees of Earth from the International Space...

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

Valleys much younger than well-known ancient valley networks on Mars are evident near the informally named "Heart Lake" on Mars. This map presents color-coded topographical information overlaid ont...

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

If a meteorite breaks in two shortly before hitting the ground, the typical bowl shape of a single impact crater becomes doubled.

This is a Mars Odyssey visible color image of an unnamed crater in western Arcadia Planitia (near 39 degrees N, 179 degrees E). The crater shows a number of interesting internal and external featur...

Taken on April 24, 2019, this rainbow-colored image shows the Martian moon Phobos, as viewed by NASA's 2001 Mars Odyssey orbiter using its infrared camera, THEMIS. Each color represents a different...

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.

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

A group of small, unnamed craters in the martian southern hemisphere is the first site captured by a group of middle school students who are operating the camera system onboard NASA's Mars Odyssey ...

This image from NASA's 2001 Mars Odyssey spacecraft shows part of the caldera floor of Arsia Mons. Arsia Mons is the southernmost of the Tharsis volcanoes. It is 270 miles in diameter, almost 12 mi...

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

Mars program Chief Engineer Robert Shotwell describes Mars Odyssey's unprecedented view of comet Siding Spring as the comet sweeps by the Red Planet on Oct. 19 and how it will maneuver to take images.

NASA Science missions circle Earth, the Sun, the Moon, Mars and many other destinations within our solar system, including spacecraft that look out even further into our universe. The Science Fleet...

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.

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. The frame is about 14 kilometers (9 miles) wide.

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

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

The floor of this crater in Terra Sirenum contains layered material. The layered sedimentary material on Mars is arguably the most interesting and compelling material on the planet. These layers mo...

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