Impact Crater in Tempe Terra

With the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument just above his head, a technician at NASA’s Kennedy Space Center works on the Mars Reconnaissance Orbiter spacecraft...

This chain of collapse pits located on the southeast flank of Alba Patera, a volcanic complex, probably formed when empty underground lava tubes collapsed.

Hitting a moving target over 306 million miles away is no easy feat. Learn how JPL navigation engineers have guided the Mars Reconnaissance Orbiter toward its mission-critical capture into orbit ar...

How can you communicate with Mars spacecraft when the Sun is in the way? Learn more about 'solar conjunction' in this 60-second video.

The smaller, narrow ridges oriented vertically are yardangs, which are created by wind erosion; the wind strips away the surrounding terrain, and the ridges remain because they contain more hardene...

This image covers plains near Aureum Chaos.

This nearly global mosaic of observations made by the Mars Color Imager on NASA's Mars Reconnaissance Orbiter on Nov. 18, 2012, shows a dust storm in Mars' southern hemisphere.

This sequence of images shows a blast zone where the sky crane from NASA's Curiosity rover mission hit the ground after setting the rover down in August 2012, and how that dark scar's appearance ch...

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 image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows distinct bands of alternating tone and brightness within the "Murray Formation" on Mars.

NASA's Mars Reconnaissance Orbiter has been observing Mars since 2006, enabling it to document many types of changes, such as the way winds alter the appearance of this recent impact site. The orbi...

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...

NASA’s InSight has been busy. After landing on the Red Planet, the mission sent home pictures and sound, then placed its first instrument on the planet's surface. Plus, find out what the Curiosity ...

In February 2015, NASA's Mars Exploration Rover Opportunity is approaching a cumulative driving distance on Mars equal to the length of a marathon race. This map shows the rover's position relative...

Dark, narrow streaks on Martian slopes such as these at Hale Crater are inferred to have been formed by seasonal flow of water on contemporary Mars. Detection of hydrated salts at the streaks suppo...

This enhanced image shows the inside of a rimless pit about 310 meters (1,017 feet) in diameter, northwest of the mountain Ascraeus Mons in the northern hemisphere of Mars.

Researchers estimating the amount of carbon held in the ground at the largest known carbonate-containing deposit on Mars utilized data from three different NASA Mars orbiters.

Dunes are often found on crater floors. In the winter, at high northern latitudes, the terrain is covered by carbon-dioxide ice (dry ice).

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...

This April 6, 2014, image from the Context Camera on NASA's Mars Reconnaissance Orbiter was taken as a follow-up to discovery of a possible 2012 impact scar in images from the orbiter's Mars Color ...

This sequence of seven images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows wind-caused changes in the parachute of NASA's Mars Sci...

Mars Reconnaissance Orbiter Project Manager Jim Graf hugs Jet Propulsion Laboratory Director Dr. Charles Elachi after a successful orbit insertion on March 10, 2006.

This image includes an especially long example of a type of dark marking that advances down some Martian slopes in warmer months and fades away in cooler months.

The Mars Reconnaissance Orbiter has seen many places on the planet. One of the most interesting is one of the great canyon systems on Mars.

This 3D, or stereo anaglyph, view shows the upcoming science destination for NASA's Mars rover Curiosity, a region dubbed "Glenelg," where three different types of material seen from orbit come tog...
