Countdown Nears: Final Tests

This 3D, or stereo anaglyph, view shows NASA's Mars rover Curiosity where it landed on Mars within Gale Crater, at a site now called Bradbury Landing. The view was produced from images taken by the...

This image from NASA's Mars Reconnaissance Orbiter shows channels to the southeast of Hale crater on southern Mars. Taken by the orbiter's High Resolution Imaging Science Experiment (HiRISE) camera...

NASA's Curiosity Mars rover used its Navigation Camera (Navcam) on April 11, 2014, to record this scene of a butte called "Mount Remarkable" and surrounding outcrops at a waypoint called "the Kimbe...

Images of locations in Gale Crater taken from orbit around Mars reveal evidence of erosion in recent geological times and development of small scarps, or vertical surfaces.

NASA is advancing the Journey to Mars by starting the conversation about where humans may one day land on the Red Planet.

This image from NASA's Mars Reconnaissance Orbiter shows a hill with a central crater. Such features have been interpreted as both mud volcanoes (really a sedimentary structure) and as actual volca...

This pair of before (left) and after (right) images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter documents formation of a new channel on...

Part of the canyon floor and wall rock in southwestern Melas Chasma on Mars meanders in a pattern resembling a dragon.

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 animation shows the position of NASA's Curiosity rover as it journeyed through "the clay-bearing unit" on Mars between May 31 and July 20, 2019. The HiRISE camera on NASA's Mars Reconnaissance...

This image acquired on October 1, 2020 by NASAs Mars Reconnaissance Orbiter, shows several craters in Arabia Terra filled with layered rock.

This image shows an outcrop of the south polar layered deposits (SPLD). The SPLD consist of layers of ice and admixed dust and make up the bulk of the dome-shaped Planum Australe.

This is an image of a central pit of an impact crater in the Martian ancient highlands.

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...

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.

The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard NASA's Mars Reconnaissance Orbiter obtained this spectrum for comet C/2013 A1 Siding Spring during the comet's close approach...

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...

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...

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...

This image combines a photograph of seasonal dark flows on a Martian slope with a grid of colors based on data collected by a mineral-mapping spectrometer observing the same area.

This global map of Mars was acquired on Aug. 2, 2012, by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter.

These dark streaks, also known as “slope streaks,” resulted from dust avalanches on Mars. The HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter captured them on Dec. 26, 2017.

This image features an exhumed crater in Meridiani Planum, an equatorial region where the rover Opportunity has been exploring the Martian surface since January 2004. An exhumed crater is one that ...

The total distance driven by NASA's Mars rover Curiosity passed the one-mile mark a few days before the first anniversary of the rover's landing on Mars.

This series of images shows warm-season features that might be evidence of salty liquid water active on Mars today.
