Countdown Nears: Final Tests

Deposits on the floor of Palos Crater

Gale Crater forms a large natural repository for much of Martian geologic history.

This map shows the route on lower Mount Sharp that NASA's Curiosity followed between April 19, 2015, and Nov. 5, 2015. During this period the mission investigated silica-rich rock targets includin...

This image shows blocks of bright, layered rock embedded in darker material that are thought to have been deposited by a giant flood that occurred when Uzboi Valles breached the rim of Holden Crater.

This sinuous raised ridge is thought to be an inverted stream channel.  These are formerly low-lying streambeds that became elevated because the original depression is filled with materials (such a...

With the Atlantic Ocean as a backdrop, an Atlas V launch vehicle, 19 stories tall, with a two-ton Mars Reconnaissance Orbiter on top, roars away from Launch Complex 41 at Cape Canaveral Air Force S...

The enhanced-color subimage shows a great variety of colors and textures in the bedrock, where it is exposed from beneath a dark fine-grained mantle. The mantle is sometimes modified by the wind in...

Mars Reconnaissance Orbiter Project Manager Jim Graf shakes the hand of JPL Associate Director for Programs, Project Formulation and Strategy Dr. Firouz Naderi. They are celebrating the spacecraft'...

This HiRISE image covers the southwest portion of the terraces and floor of Holden Crater situated in southwest Margaritifer Terra.

This cross-section view of underground layers near Mars' south pole is a radargram based on data from the Shallow Subsurface Radar (SHARAD) instrument on NASA's Mars Reconnaissance Orbiter

Phobos in Stereo

This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows sedimentary-rock layering in which a series of layers are all approximatel...

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter took two images of the larger of Mars' two moons, Phobos, within 10 minutes of each other on Mar...

Gullies on Martian sand dunes, like these in Matara Crater, have been very active, with many flows in the last ten years. In this image from NASA's Mars Reconnaissance Orbiter frost in and around t...

This image acquired on December 13, 2020 by NASAs Mars Reconnaissance Orbiter, shows blobby features in the polar cap that are due to the sun sublimating away the carbon dioxide into these round pa...

This observation from NASA's Mars Reconnaissance Orbiter shows a sand dune field in the Nili Fossae region of Mars. The dark lines swirling over the surface of the dunes are the tracks of dust devi...

NASA's Curiosity Mars rover used its Navigation Camera (Navcam) to record this stereo scene of a butte called "Mount Remarkable" and surrounding outcrops at a waypoint called "the Kimberley" inside...

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 ...

The largest crater in this mosaic of images taken by the Context Camera on NASA's Mars Reconnaissance Orbiter is Endeavour Crater, which is 22 kilometers (14 miles) in diameter.

Sand dunes such as those seen in this image have been observed to creep slowly across the surface of Mars through the action of the wind.

This image acquired on December 8, 2018 by NASAs Mars Reconnaissance Orbiter, shows erosion of the surface revealing several shades of light toned layers, likely sedimentary deposits.

Drainage Near Crater in Terra Sabaea.

The Global CTX Mosaic of Mars allows scientists and the public to explore the planet like never before. 

Dust-Mantled Topography near Zephyria Tholus

This image from NASA's Mars Reconnaissance Orbiter shows an impact crater that triggered a slope streak. When a meteoroid hit the surface and exploded to make the crater, it destabilized the slope ...
