Eridania Basin Light-Toned Outcrops

This map indicates some of the geological information gained from orbital observations of Endeavour Crater, which has been the long-term destination for NASA's Mars Exploration Rover Opportunity si...

This map shows where NASA's Mars rover Curiosity has driven since landing at a site subsequently named "Bradbury Landing," and traveling to an overlook position near beside "Point Lake," in drives ...

Several types of downhill flow features have been observed on Mars. This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter is an exampl...

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter captured winter images of NASA's Phoenix Mars Lander surrounded by dry-ice frost on Mars.

The rock layers in this image were likely horizontal when the materials were first deposited, but are now tilted to high angles, approaching 90 degrees.

This image acquired on April 8, 2018 by NASA's Mars Reconnaissance Orbiter, shows the gullied western slopes of an unnamed crater (about 10 kilometers wide) in Acidalia Planitia.

This animation demonstrates the salty ponds and streams that scientists think may have been left behind as Gale Crater dried out over time. The bottom of the image is the floor of Gale Crater, with...

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.

This image from NASA's Mars Reconnaissance Orbiter (MRO) shows the permanent polar cap of Mars, encircled by sand dunes and looking like pulled threads. These dunes march across a fabric of pattern...

This image, acquired on May 15, 2018, by NASA's Mars Reconnaissance Orbiter, shows relatively bright mounds scattered throughout darker and diverse surfaces in Chryse Planitia.

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.

Mawrth Vallis has a rich mineral diversity, including clay minerals that formed by the chemical alteration of rocks or loose “regolith” (soil) by water.

This image shows the topography, with shading added, around the area where NASA's Curiosity rover landed on Aug. 5 PDT (Aug. 6 EDT).

This image captures a fairly rare situation. In general, as lava flows along, it fills in low points and holes it encounters in its path and flows around high points such as hills and ridges. In th...

A comparison of two radargrams from the SHARAD instrument on NASA's Mars Reconnaissance Orbiter shows effects on the Martian ionosphere from the close passage of a comet.

This view of layered rocks on the floor of McLaughlin Crater shows sedimentary rocks that contain spectroscopic evidence for minerals formed through interaction with water.

This series of images shows carbon dioxide ice sublimating (going directly from a solid to a gas) inside a pit at Mars' south pole. Each frame of the animation was taken by the HiRISE camera on NAS...

This scene shows dark sand dunes marching over the ridges created by an alluvial (water-deposited) fan in an impact crater.

This impact crater appears relatively recent as it has a sharp rim and well-preserved ejecta, the material thrown out of the crater when a meteorite hit Mars.

On Nov. 1, 2016, the HiRISE camera on NASA's Mars Reconnaissance Orbiter observed the impact site of Europe's Schiaparelli test lander, gaining the first color view of the site since the lander's O...

This image shows NASA's Mars Exploration Rover Opportunity perched on the edge of "Concepción" crater in Meridiani Planum, Mars.

This image shows part of Ladon Vallis that is located within Ladon basin.

Phobos from 6,800 Kilometers

This oblique view with moderate vertical exaggeration shows the portion of the rim of Endeavour crater given the informal name "Spirit Point." This is the location where the team operating NASA's ...

This illustration depicts a concept for the possible extent of an ancient lake inside Gale Crater.
