Artist concept of Glaciers on Mars

The feature that appears bright blue at the center of this scene is NASA's Curiosity Mars rover on the northwestern flank of Mount Sharp, viewed by NASA's Mars Reconnaissance Orbiter. Curiosity is ...

NASA's Mars Reconnaissance Orbiter dips into the thin martian atmosphere to adjust its orbit in this artist's concept illustration.

On this map of Mars, areas indicated in green are where spectrometers on spacecraft orbiting Mars have detected clay minerals and areas indicated in blue are where those spectrometers have detected...

Shown in this image from NASA's Mars Reconnaissance Orbiter are fan-shaped deposits emerging from regions of steep topography called alluvial fans. Alluvial fans on Mars are thought to be ancient a...

This map shows the route driven by NASA's Curiosity Mars rover from the location where it landed in August 2012 to its location in mid-November 2015, approaching examples of dunes in the "Bagnold D...

This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows the transition between the "Murray Formation," in which layers are poorly expressed and difficult to tra...

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?

This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows the transition between the "Murray Formation," in which layers are poorly expressed and difficult to tra...

The Global CTX Mosaic of Mars allows scientists and the public to explore the planet like never before. 

This kickoff of a new Mars video series covers Opportunity's 14th anniversary on the Red Planet, Curiosity's spectacular panorama and ice deposits spotted by an orbiter.

This view taken from orbit around Mars shows the sand dune that will be the first to be visited by NASA's Curiosity Mars Rover along its route to higher layers of Mount Sharp.

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.

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...

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.

Lucus Planum is a part of the enigmatic Medusa Fossae Formation, a broad, soft, and easily eroded deposit. Here this deposit is thin and considerably rougher than elsewhere, implying that it is hea...

Mars Reconnaissance Orbiter is Off to Mars!

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

The colorful rocks exposed in the central peak visible in this image probably reflect variations in mineral content that were caused by water activity early in Mars' history. The CRISM hyperspectra...

This image from NASA's Mars Reconnaissance Orbiter is a close-up of a trough, along with channels draining into the depression. On the floor of the trough is some grooved material typically seen in...

NASA's spacecraft on Mars are all affected by the winds of the Red Planet, which can produce a tiny dust devil or a global dust storm. 

This image shows the floor of Ius Chasma

This illustration schematically shows where the Shallow Radar instrument on NASA's Mars Reconnaissance Orbiter detected flood channels that had been buried by lava flows in the Elysium Planitia reg...

An enhanced-color image from NASA's Mars Reconnaissance Orbiter (MRO) reveals bedrock that is several kilometers below the top of the giant Valles Marineris canyons.

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 map traces where NASA's Mars rover Curiosity drove between landing at a site subsequently named "Bradbury Landing," and the position reached during the mission's 130th Martian day, or sol, (De...
