Impact Crater in Tempe Terra

An oblique, northward-looking view based on stereo orbital imaging, shows the location of Opportunity on its journey from Cape York to Solander Point when HiRISE took the new color image.

This view shows the ground covered in the first image of Mars taken by the High Resolution Imaging Science Experiment camera (HiRISE) on NASA's Mars Reconnaissance Orbiter

The Mars Climate Sounder, an instrument on NASA's Mars Reconnaissance Orbiter designed to monitor daily changes in the global atmosphere of Mars, made its first observations of Mars on March 24, 2006.

NASA's Opportunity Mars rover, working on Mars since January 2004, passed marathon distance in total driving on March 24, 2015. This map shows the rover's entire traverse from landing to that point.

NASA's Mars Exploration Rover Opportunity has been on the western rim of Endeavour Crater in Meridiani Planum for about two years. Until May 2013, it was investigating sedimentary layers that are ...

A view from NASA's Mars Reconnaissance Orbiter on April 8, 2015, catches sight of NASA's Curiosity Mars rover passing through a valley called "Artist's Drive" on the lower slope of Mount Sharp.

This image shows the location of the rover-containing section of new color image in relation to Solander Point.

This image shows part of the floor of an impact crater on the northern rim of the giant Hellas Basin.

This map shows the route driven by NASA's Mars rover Curiosity through the 56th Martian day, or sol, of the rover's mission on Mars (Oct. 2, 2012).

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 animation demonstrates the salty ponds and streams that scientists think may have been left behind as Gale Crater dried out over time. The bottom of the image is the floor of Gale Crater, with...

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

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 Mars Climate Sounder instrument on NASA's Mars Reconnaissance Orbiter maps the vertical distribution of temperatures, dust, water vapor and ice clouds in the Martian atmosphere as the orbiter f...

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...

This 3D, or stereo anaglyph, view shows the parachute and back shell that helped guide NASA's Curiosity to the surface of Mars. The view was produced from images taken by the High Resolution Imagin...

This image from NASA's Mars Reconnaissance Orbiter (MRO) shows the permanent polar cap of Mars, encircled by sand dunes and looking like pulled threads. These dunes march across a fabric of pattern...

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter acquired this color image on March 9, 2011, of "Santa Maria" crater, showing NASA's Mars Explora...

This comparison of before-and-after images shows two spots that likely appeared in connection with the Oct. 19, 2016, Mars arrival of the European Space Agency's Schiaparelli test lander. The image...

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 ...

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

This map shows the route driven by NASA's Mars rover Curiosity through the 29th Martian day, or sol, of the rover's mission on Mars (Sept. 4, 2012).

Sand dunes often accumulate in the floors of craters. In this region of Lyot Crater, NASA's Mars Reconnaissance Orbiter (MRO) shows a field of classic barchan dunes on Jan. 24, 2018.

This image covers a region of Mars near Nili Fossae that contains some of the best exposures of ancient bedrock on Mars.
