Terrain in Vastitas Borealis Region

Snow falls and ice and frost form on Mars, too. NASA's spacecraft on and orbiting the Red Planet reveal the similarities to and differences from how we experience winter on Earth.  

Gullied Crater Slope with Rocky Outcrops Northeast of Hellas Region

This image shows layered blocks tilted at high angles, diverse color and textures and dark dunes. Some of the bedrock may have originated at great depths, uplifted first by Becquerel Crater and lat...

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

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...

Newly detailed mapping of local variations in Mars' gravitational pull on orbiters (center), combined with topographical mapping of the planet's mountains and valleys (left), yields the best-yet ma...

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...

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 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 ...

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.

These views of sites where hardware from Europe's Schiaparelli test lander hit Mars on Oct. 19, 2016, combine two HiRISE camera orbital views from different angles, as a stereo pair for viewing wit...

The yellow 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 a po...

This image acquired on April 8, 2018 by NASA's Mars Reconnaissance Orbiter, shows the gullied western slopes of an unnamed crater (about 10 kilometers wide) in Acidalia Planitia.

These color-enhanced views of Deimos, the smaller of the two moons of Mars, were taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

What triggered a Martian landslide? Landslides are common features in canyons on both Earth and Mars, and they happen the same way.

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...

The HiRISE camera on the Mars Reconnaissance Orbiter is the most powerful telescope to have left Earth orbit. HiRISE is capable of some interesting astronomical observations such as this image of J...

These images were taken of comet C/2013 A1 Siding Spring by NASA's Mars Reconnaissance Orbiter on Oct. 19, 2014, during the comet's close flyby of Mars and the spacecraft.

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter snapped this series of false-color pictures of sand dunes in the north polar region of Mars

This composite graphic illustrates the use of the Shallow Radar instrument on NASA's Mars Reconnaissance Orbiter for mapping underground ice-rich layers of the north polar layered terrain on Mars.

This Oct. 25, 2016, image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows the area where the Europe's Schiaparelli test lander struck Mars, with magnified insets of three sites w...

Dunes on Floor of Samara Valles, Mars

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 September 2016 at "Murray Buttes," and the path planned for reachi...

NASA's Curiosity Mars rover and its tracks are visible in this view combining information from three observations by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Re...

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.
