Storm Chaser on Mars

This crater, formed in 2008, exposes shallow, clean ice that is not uncommon in the middle-to-high latitudes on Mars.

This image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows a location associated with the novel and movie, "The Martian." It is the tale's planned landing site for the Ares 4 mis...

This image reveals exposed layers in Noctis Labyrinthus which may contain signatures of iron bearing sulfates and phyllosilcate (clay) minerals.

A rippled dune front in Herschel Crater on Mars moved an average of about one meter (about one yard) between March 3, 2007 and December 1, 2010, as seen in these images from NASA's Mars Reconnaissa...

There are steep scarps facing the poles of both hemispheres that expose thick (up to 100 meters or more) sections of nearly pure water ice.

Unfrozen brine in cryopegs and fracture networks provides habitats for the survival and growth of organisms both within and under frozen rocky materials on Earth and, by analogy, could provide habi...

This scene shows dark sand dunes marching over the ridges created by an alluvial (water-deposited) fan in an impact crater.

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 map indicates geological units in the region of Mars around a smaller area where NASA's Mars Exploration Rover Opportunity has driven from early 2004 through late 2010.

This graph shows a spectrum recorded by the Chemistry and Camera instrument (ChemCam) in NASA's Curiosity Mars rover.

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 December 2015, at examples of the Bagnold Dunes.

A new map of Mars' gravity made with three NASA spacecraft is the most detailed to date, providing a revealing glimpse into the hidden interior of the Red Planet. Satellites always orbit a planet's...

This image acquired on October 28, 2018 by NASAs Mars Reconnaissance Orbiter, shows that gullies probably formed along the bouldery layers in the upper slopes of this unnamed crater.

The smaller, narrow ridges oriented vertically are yardangs, which are created by wind erosion; the wind strips away the surrounding terrain, and the ridges remain because they contain more hardene...

This mosaic, taken with the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter, shows the planned route (in yellow) of NASA's Curiosity rover from "Pah...

This movie sequence of images from NASA's Mars Reconnaissance Orbiter (MRO) shows comet C/2013 A1 Siding Spring before and after its close pass by Mars in October 2014. False color enhances subtle ...

NASA's Curiosity rover and its parachute were spotted by NASA's Mars Reconnaissance Orbiter as Curiosity descended to the surface on Aug. 5 PDT (Aug. 6 EDT).

Dark, narrow streaks on Martian slopes such as these at Hale Crater are inferred to have been formed by seasonal flow of water on contemporary Mars. Detection of hydrated salts at the streaks suppo...

CRISM observations of this region of the Noctis Labyrinthus formation have shown indications of iron-bearing sulfates and phyllosilicate (clay) minerals.

Recurring slope lineae (RSL) are active flows on warm Martian slopes that might be caused by seeping water.

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

This color view of the parachute and back shell that helped deliver NASA's Curiosity rover to the surface of the Red Planet was taken by the High-Resolution Imaging Science Experiment (HiRISE) came...

A newly found, buried deposit of frozen carbon dioxide -- dry ice -- near the south pole of Mars contains about 30 times more carbon dioxide than previously estimated to be frozen near the pole.

The yellow-white cloud in the bottom-center of this image is a Mars "dust tower" — a concentrated cloud of dust that can be lofted dozens of miles above the surface. The blue-white plumes are water...
