Impact Crater in Tempe Terra

Two parallel tracks left by the wheels of NASA's Curiosity Mars rover cross rugged ground in this portion of a Dec. 11, 2013, observation by the High Resolution Imaging Science Experiment (HiRISE) ...

This HiRISE image covers the southwest portion of the terraces and floor of Holden Crater situated in southwest Margaritifer Terra.

This artist's concept of NASA's Mars Reconnaissance Orbiter at Mars features one of its instruments -- the Mars Climate Sounder -- in action.

This map shows the route driven by NASA's Curiosity Mars rover from the "Bradbury Landing" location where it landed in August 2012 (the start of the line in upper right) to a major waypoint called ...

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

This picture of a heart-shaped pit was taken on 26 February 2008 by the CTX camera aboard MRO. It is approximately 2 km long. The pit is one of many adjacent to Hydaspis Chaos, a jumbled topographi...

NASA's Mars Science Laboratory rover Curiosity appears as a bluish dot near the lower right corner of this enhanced-color view from the High Resolution Imaging Science Experiment (HiRISE) camera on...

This map shows the route driven by NASA's Curiosity Mars rover from the "Bradbury Landing" location where it landed in August 2012 (the start of the line in upper right) to a major waypoint called ...

NASA Science missions circle Earth, the Sun, the Moon, Mars and many other destinations within our solar system, including spacecraft that look out even further into our universe. The Science Fleet...

Color has been added to highlight minerals in this image of Jezero Crater on Mars, the landing site for NASA's Mars 2020 mission. The green color represents minerals called carbonates, which are es...

NASA's Mars Reconnaissance Orbiter has revealed Martian rocks containing a hydrated mineral similar to opal. The rocks are light-toned and appear cream-colored in this false-color image taken by th...

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...

This image acquired on August 1, 2018 by NASAs Mars Reconnaissance Orbiter, shows the Martian south polar cap full of pits that make it look like Swiss cheese.

An image combining orbital imagery with 3-D modeling shows flows that appear in spring and summer on a slope inside Mars' Newton crater.

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...

The gullies on a Martian sand dune in this trio of images from NASA's Mars Reconnaissance Orbiter deceptively resemble features on Earth that are carved by streams of water.

The black speck circled in the lower left corner of this image is a cluster of recently formed craters spotted on Mars using a new machine-learning algorithm. This image was taken by the Context Ca...

This artist's animation shows how orbiters over Mars will monitor the landing of NASA's Curiosity rover. (No audio)

Impact cratering and erosion combine to reveal the composition of the Martian underground by exposing materials from the subsurface.

This crater is named for G. Edward Danielson, Jr. who was instrumental in the development of a series of Mars cameras, from Mariner 4 launched in 1964 to the Mars Global Surveyor launched in 1996.

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

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

Nili Fossae was once considered a potential landing spot for the Mars Science Laboratory, and has one of the largest, most diverse exposures of clay minerals.

Follow along on a tour of the landing scene of NASA's Curiosity rover in this video made up of images from two NASA orbiters. The movie begins with a global image from NASA's Mars Global Surveyor, ...
