Planum Boreum crater

A small basin (center foreground) lies below the southern rim of Melas Chasma, part of Valles Marineris.

This mosaic of infrared images shows the abundance and location of hematite at Opportunity's landing site, Meridiani Planum. On Earth, hematite is a mineral that typically forms in water.

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...

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

Continuing our survey of non-crater dune fields brings us to this group of dunes in Aonia Terra. The daytime IR illustrates the warmth of the dune material compared to the surrounding materials.

A false-color mosaic focuses on one junction in Noctis Labyrinthus where canyons meet to form a depression 4,000 meters (13,000 feet) deep.

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.

This map of Mars indicates locations of new craters that have excavated ice (blue) and those that have not (red). The underlying map is based on the brightness, or albedo, of the Martian surface.

A "Grand Canyon of Mars" slices across the Red Planet near its equator.

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.

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...

This THEMIS image of rounded hills and ridges in Arcadia Planitia shows a very intriguing geomorphic feature that may be attributed to the presence of an icy-rock mixture of material. Smooth aprons...

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 ...

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

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

Chasma Boreale is a long, flat-floored valley that cuts deep into Mars' north polar icecap

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 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.

Bright blue marks a deposit of chloride (salt) minerals in the southern highlands of Mars in this false-color image, which highlights mineral composition differences.

This image of Phobos is one product of the first pointing at that Martian moon by the THEMIS camera on NASA's Mars Odyssey orbiter.  The Sept. 29, 2017, observation also provided information about ...

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.

This animation shows how NASA's Curiosity rover communicates with Earth via two of NASA's Mars orbiters, Mars Reconnaissance Orbiter (MRO) and Odyssey, and the European Space Agency's Mars Express....

This image from NASAs Mars Odyssey shows lava flows from Alba Mons, and a tectonic graben called Cyane Fossae.

This graphic depicts the relative shapes and distances from Mars for five active orbiter missions plus the planet's two natural satellites. It illustrates the potential for intersections of the spa...
