Storm Chaser on Mars

This is a close-up of the area in the vicinity of the Pathfinder landing site. Major features are named. The white box outlines the area of the image, where hardware is seen.

Seasons change even on Mars and NASA's fleet of explorers are helping scientists learn more about the effects on the Red Planet.

This area at the base of Mount Sharp on Mars includes a pale outcrop, called "Pahrump Hills," that NASA's Curiosity Mars rover investigated from September 2014 to March 2015, and the "Artist's Driv...

These two infrared images of comet C/2013 A1 Siding Spring were taken by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard NASA's Mars Reconnaissance Orbiter on Oct. 19, 2014....

This HiRISE image shows gullies on a south-facing slope of a crater touched with late-Spring carbon dioxide frost. At this time of year, only the south-facing slopes of craters retain their frost, ...

This picture of a heart-shaped feature in Arabia Terra on Mars was taken on May 23, 2010, by the Context Camera (CTX) on NASA's Mars Reconnaissance Orbiter.

NASA's Mars Exploration Rover Opportunity has been on the western rim of Endeavour Crater in Meridiani Planum for about two years.

These images from the NASA Mars Reconnaissance Orbiter show several impact scars on Mars made by pieces of the NASA Mars Science Laboratory spacecraft that the spacecraft shed just before entering ...

This full-resolution color image from NASA's Curiosity Rover shows the gravel-covered surface of Mars. It was taken by the Mars Descent Imager (MARDI) several minutes after Curiosity touched down o...

This April 6, 2014, image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows numerous landslides in the vicinity of where an impact crat...

NASA's Mars Reconnaissance Orbiter, nearing the 10th anniversary of its arrival at Mars, used its High Resolution Imaging Science Experiment (HiRISE) camera to obtain this view of an area with unus...

A digital terrain model generated from a stereo pair of images provides this synthesized, oblique view of a portion of the wall terraces of Mojave Crater in the Xanthe Terra region of Mars.

A dramatic, fresh impact crater dominates this image taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on Nov. 19, 2013.

Stokes Crater, pictured here, is one of at least nine craters in the northern lowlands of Mars with exposures of hydrated minerals detected from orbit, according to a June 25, 2010, report.

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...

What appear to be spiders scampering across the martian landscape are actually cracks in the surface of the southern polar region on Mars, seen by the Mars Reconnaissance Orbiter on August 23, 2009...

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...

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.

This picture of a crater resembling a "happy face" was taken in January 2008, by the Mars Reconnaissance Orbiter's Context Camera. The unnamed crater is almost 2 miles (about 3 kilometers) across.

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 123rd Martian day, or sol, (De...

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

These images from orbit show an area near Mars' south pole where coalescing or elongated pits are interpreted as signs that an underlying deposit of frozen carbon dioxide, or "dry ice," has been sh...

Why does HiRISE take so many repeat images of the same area? Repeat coverage actually serves a special purpose, such as detecting seasonal changes (frost deposition and sublimation) and temporal ch...

A radar on NASA's Mars Reconnaissance Orbiter has detected widespread deposits of glacial ice in the mid-latitudes of Mars.

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.
