Countdown Nears: Final Tests

This graphic presents Martian atmospheric temperature data as curtains over an image of Mars taken during a regional dust storm. The temperature profiles extend from the surface to about 50 miles u...

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

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).

This image is located within Northern Sinus Meridiani, a region of ridged terrains and extensive stratigraphic layering. 

Mars is experiencing large regional dust storms over its northern hemisphere during the past week.

Mysterious features on slopes hint there could be water flows on Mars.

This image from orbit covers an area about 460 meters (about 1,500 feet) across, in which carbonate minerals have been identified from spectrometer observations. Fractures and possible layers are v...

This map shows five locations where fresh impact cratering has excavated water ice from just beneath the surface of Mars (sites 1 through 5) and the Viking Lander 2 landing site (VL2), in the conte...

This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows gullies near the edge of Hale crater on southern Mars. The view covers an ...

This DLE [double layer ejecta] crater formed at the edge of an older/pre-existing crater, the rim of which deflected some of its ejecta.

The red 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 where i...

As the Sun peeks above the horizon at the Martian south polar icecap, powerful jets of carbon-dioxide (CO2) gas erupt through the icecap's topmost layer.

This series of images shows carbon dioxide ice sublimating (going directly from a solid to a gas) inside a pit at Mars' south pole. Each frame of the animation was taken by the HiRISE camera on NAS...

Dunes on Floor of Samara Valles, Mars

This image from NASA's Mars Reconnaissance Orbiter shows an impact crater that triggered a slope streak. When a meteoroid hit the surface and exploded to make the crater, it destabilized the slope ...

This map shows the route driven by NASA's Mars rover Curiosity through the 56th Martian day, or sol, of the rover's mission on Mars (Oct. 2, 2012).

NASA's Curiosity Mars rover can be seen at the "Pahrump Hills" area of Gale Crater in this view from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orb...

A small channel cuts across the floor of a gigantic 1100-mile (1780-kilometer)-long set of flood-carved channels in a region on Mars called "Kasei Valles."

Tracks from the first drives of NASA's Curiosity rover are visible in this image captured by the High-Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

The long, sinuous raised ridges on this fan of material are thought to be inverted stream channels. These ridges may have been low-lying streambeds that hardened and then turned into ridges when th...

Streamlined forms in this Martian valley resulted from the outflow of a lake hundreds of millions years more recently than an era of Martian lakes previously confirmed. This image from the Context ...

This image acquired on January 27, 2019 by NASAs Mars Reconnaissance Orbiter, shows the extensive central peak complex of Hale Crater.

The bright linear features cutting the bedrock in the center region of this image look like mineral veins.

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...
