Artist concept of Glaciers on Mars

This image acquired on January 13, 2019 by NASAs Mars Reconnaissance Orbiter, shows a cluster of dust devil tracks on the flat ground below the south polar layered deposits, but none on the layers ...

The Mars Climate Sounder instrument, shown here prior to its installation onto NASA's Mars Reconnaissance Orbiter for the mission's 2006 launch, will get a similar-looking sibling at Mars in 2016.

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 image shows the transitional terrain where the linear troughs and rounded pits of an area called "Noctis Labyrinthus" merge with the larger canyon of "Valles Marineris." Unusual bright blocks ...

This unnamed impact crater is about 8 kilometers in diameter and contains numerous gullies.

This impact crater has gullies incised into its walls on the north and eastern sides. A couple of gullies on the north wall are unusual because a segment in the middle becomes wider than the upslop...

The Mars Reconnaissance Orbiter took this photo of the Curiosity rover in September 2015, as Curiosity was exploring the boundary between two rock units: the light-toned Murray Formation and the ov...

Getting a spacecraft to Mars is no walk in the park - as launch engineers are well aware. But when the spacecraft in question is among the largest ever sent to the red planet, there are specific ch...

Explanation on how CRISM hyperspectral images are used to understand the history and formation of Valles Marineris, one of the largest canyons in the solar system, and how the data is used to unrav...

This animation shows NASA's Mars Reconnaissance Orbiter flying over NASA's Curiosity (shown in pink) as the rover lands on the Red Planet. The video is slowed down as the orbiter approaches the lan...

The HiRISE camera on NASA's Mars Reconnaissance Orbiter got its best view yet of the agency's InSight lander on Sept. 23, 2019.

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...

How before-and-after pictures led to the discovery of a fresh meteor impact crater on Mars.

A view from NASA's Mars Reconnaissance Orbiter on April 8, 2015, catches sight of NASA's Curiosity Mars rover passing through a valley called "Artist's Drive" on the lower slope of Mount Sharp.

This map shows the thickness of the north polar layered deposits on Mars as measured by the Shallow Radar instrument on NASA's Mars Reconnaissance Orbiter.

A hill with a V-shaped collapse structure, two craters and a circular fracture pattern — possibly the remains of a buried impact crater — appear to form the face of a bear on the Mars surface. This...

This map shows the route driven by NASA's Mars rover Curiosity through the 43rd Martian day, or sol, of the rover's mission on Mars (Sept. 19, 2012).

A variety of landforms, including isolated hills, eroded mesas, dark eroded sediments, and dunes are seen within an area called "Aram Chaos."

This view combines information from two instruments on NASA's Mars Reconnaissance Orbiter to map color-coded composition over the shape of the ground in a small portion of the Nili Fossae plains re...

This image acquired on December 3, 2018 by NASAs Mars Reconnaissance Orbiter, shows a cross-section of a dune field. Dune shape depends on several factors, including the amount of sand present and ...

The black speck circled in the lower left corner of this image is a cluster of recently formed craters spotted on Mars using a new machine-learning algorithm. This image was taken by the Context Ca...

Wind is one of the most active forces shaping Mars’ surface in today’s climate. Wind-carved features such as these, called “yardangs,” are common on the Red Planet.

This terrain is covered by pits and scallops (pits open on one side), perhaps due to collapse after sublimation of subsurface ice.

This picture of a heart-shaped pit was taken on 26 February 2008 by the CTX camera aboard MRO. It is approximately 2 km long. The pit is one of many adjacent to Hydaspis Chaos, a jumbled topographi...

In the novel and movie "The Martian," an astronaut's adventures take him to the rim of Mawrth Crater. This image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows the nature of thi...
