The dunes in this VIS image are located in Aonia Terra.

In Ares Vallis, teardrop mesas extend like pennants behind impact craters, where the raised rocky rims diverted the floods and protected the ground from erosion.

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.

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.

Artist’s concept of Comet Siding Spring approaching Mars, shown with NASA’s orbiters preparing to make science observations of this unique encounter.

First THEMIS Image of Mars

This movie begins with an animation (artist's rendering) of NASA's Mars Reconnaissance Orbiter spacecraft above Mars. The scene zooms into an "X-ray" view of the spacecraft, revealing the High Reso...

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...

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...

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...

This mosaic of day and night infrared THEMIS images shows landslides flowed over 100 kilometers (62 miles) across the floor of Melas Chasma.

This series of images was taken in visible-wavelength light as the THEMIS camera on NASA's Mars Odyssey scanned across the Martian moon Phobos on Sept. 29, 2017. The apparent motion is due to progr...

This image captured by NASA's 2001 Mars Odyssey spacecraft shows 'streamers' of clouds created by katabatic winds at the north polar cap.

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

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

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...

This mosaic of daytime infrared images of Gusev Crater, taken by the camera system on the Mars Odyssey spacecraft, has been draped over topography data obtained by Mars Global Surveyor.

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

Around 200 kilometers long, Ravi Vallis was born in a flood of water from Aromatum Chaos.

Newly detailed mapping of local variations in Mars' gravitational pull on orbiters (center), combined with topographical mapping of the planet's mountains and valleys (left), yields the best-yet ma...

The channels in this VIS image are part of Tyrrhena Fossae on the northern flank of Tyrrhenus Mons.

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...
