Mars Reconnaissance Orbiter is Off to Mars!

This image from NASA's Mars Reconnaissance Orbiter (MRO) shows the western wall of a small pit that is located along the floor of a larger trough in Coprates Catena. Dark layers line the bottom; li...

This map shows the route driven by NASA's Curiosity Mars rover from the "Bradbury Landing" location where it landed in August 2012 (the start of the line in upper right) to a major waypoint called ...

Martian gullies as seen in the top image from HiRISE on NASA's Mars Reconnaissance Orbiter resemble gullies on Earth that are carved by liquid water. However, when they are observed with the additi...

This image acquired on December 9, 2018 by NASAs Mars Reconnaissance Orbiter, shows a recent impact in Noachis Terra in the southern mid-latitudes of Mars.

Artist's concept of Mars Reconnaissance Orbiter

MRO took this image of layered, sedimentary rocks on the floor of an impact crater north of Eberswalde Crater. Billions of years ago there may have been a lake in this crater.

This image covers a location that has been imaged several times to look for changes in gullies.

This image maps the traverse of NASA's Mars rover Curiosity from "Bradbury Landing" to "Yellowknife Bay," with an inset documenting a change in the ground's thermal properties with arrival at a dif...

By analyzing radar images like the one at top of this montage, scientists discovered evidence for a past ice age in the northern polar ice cap of Mars.

From a distance, the floor of this crater looks like a giant honeycomb or spider web. The intersecting shapes, or polygons, commonly occur in the northern lowlands of 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...

The Coloe Fossae region is a series of enclosed, intersecting canyons. The floors of the canyons in this image contain complex set of ridges and grooves that are generally parallel to the canyon wa...

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...

A dust storm continues to envelop the Red Planet and Curiosity’s labs are back in action.

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 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.

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...

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

This animation depicts a flyover of a meteoroid impact crater on Mars that’s surrounded by boulder-size chunks of ice. The animation was created using data from the High-Resolution Imaging Science ...

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 ...

This image shows the quadrangle where NASA's Curiosity rover landed, now called Yellowknife.

The material in the upper portion of this image, perhaps hardened volcanic ash deposits, is being eroded into parallel long, thin ridges called yardangs by the strong prevailing winds.

The white speck is NASA’s Perseverance rover in the “South Séítah” area of Mars’ Jezero Crater.

The HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter took this image of the Perseverance rover on Feb. 24, 2021.

This artist's concept of NASA's Mars Reconnaissance Orbiter at Mars features one of its instruments -- the Mars Climate Sounder -- in action.
