Landing Site Region

The Electris region of Mars contains some interesting features, such as the raised-relief blocks of material visible in this image.

With its cracked, blistery appearance, this mound near the center of a very large, over 5-kilometer diameter mid-latitude crater poses an interesting question: how did this form?

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter acquired this color image on March 9, 2011, of "Santa Maria" crater, showing NASA's Mars Explora...

Phobos in Stereo

Stages in the seasonal disappearance of surface ice from the ground around the Phoenix Mars Lander are visible in these images taken on Feb. 8, 2010, (left) and Feb. 25, 2010, during springtime on ...

In this HiRISE image taken within Capri Chasma, TES also detected the same crystalline gray hematite like that found at Meridiani Planum.

This HiRISE image shows a mixture of bright and dark units. The bright units have a mineral called sulfate (salty sulfuric acid) that on Earth typically forms in the presence of water as an evapori...

This animation flips back and forth between views taken in 2010 and 2014 of a Martian sand dune at the edge of Mount Sharp, documenting dune activity. The images are from the HiRISE camera on NASA'...

The yellow line on this map shows where NASA's Mars Rover Opportunity has driven from the place where it landed in January 2004 -- inside Eagle crater, at the upper left end of the track -- to a po...

This enhanced-color image shows sand dunes trapped in an impact crater in Noachis Terra, Mars.

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.

Gullied Crater Slope with Rocky Outcrops Northeast of Hellas Region

This crater has gullies on its southwest-facing walls and rim, as well as and what appears to be two separate instances of lobate (ear-shaped) material associated to its interior gullies.

Collapsing Volcano; Edge of Olympus Mons

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter caught this view of NASA's Mars Exploration Rover Opportunity on Feb. 14, 2014.

This image acquired on December 5, 2018 by NASAs Mars Reconnaissance Orbiter, shows ripples in the sand which tell us which way the wind was moving and how it was diverted around these rock formati...

This artist's concept of the Mars Reconnaissance Orbiter features the spacecraft's main bus facing down, toward the red planet.

This fresh crater is located in the northern mid-latitudes. It is designated as fresh because of its very sharp rim.

This close-up image of a dust storm on Mars was acquired by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter on Nov. 7, 2007

The insert in this image is a simulation of what the Mars Reconnaissance Orbiter's optical navigation camera images of the Martian moons Phobos and Deimos will look like.

These two images show Shallow Radar (SHARAD) instrument data from two tracks in a part of Mars' Utopia Planitia region where the orbiting, ground-penetrating radar on NASA's Mars Reconnaissance Orb...

This graph shows changes in apparent brightness of comet C/2013 A1 Siding Spring as it approached and receded from Mars, as seen by the High Resolution Imaging Science Experiment (HiRISE) camera on...

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...

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.

Images like this from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter show portions of the Martian surface in unprecedented detail.
