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.

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

Morning clouds fill Coprates Chasma on Mars in this Nov. 25, 2015, image from the THEMIS camera on NASA's Mars Odyssey. No orbiter systematically observed Mars in morning sunlight before 2015. The ...

At the time this video was released, the Odyssey team had successfully completed the third trajectory correction maneuver to adjust the spacecraft's flightpath toward its final aimpoint for entry i...

As fractures opened near the summit of Tyrrhena Patera, the ground collapsed to make pits and chains of pits aligned with the fractures. The large pit seen here is about 400 m (1,300 ft) deep.

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

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...

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.

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

Planum Boreum crater

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

The dune field in this polar region crater looks like a stubby arrow pointing the way west. This unnamed crater is located in Planum Chronium.
