Countdown Nears: Final Tests

In Aureum Chaos, the OMEGA experiment on Mars Express indicated the presence of phyllosilicates (clay minerals) which have been detected in a variety of bright outcrops and scarps. The subimage sho...

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

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 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...

The HiRISE camera on NASA's Mars Reconnaissance Orbiter got its best view yet of the agency's InSight lander on Sept. 23, 2019.

This global map of Mars was acquired on Aug. 4, 2012, by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter.

A meteorite impact that excavated this crater on Mars exposed bright ice that had been hidden just beneath the surface at this location.

The Mars Color Imager (MARCI) camera on NASA's Mars Reconnaissance Orbiter acquired a seven-band color, wide-angle view of Mars on March 24, 2006, as part of a checkout of the orbiter's payload. Th...

This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows the transition between the "Murray Formation," in which layers are poorly expressed and difficult to tra...

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 sequence of images shows a blast zone where the sky crane from NASA's Curiosity rover mission hit the ground after setting the rover down in August 2012, and how that dark scar's appearance ch...

Small impact craters usually have simple bowl shapes, but sometimes more complicated shapes can occur if the target is unusual.

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 shows part of the surface of Chryse Planitia, near the mouth of several of the giant outflow channels carved by massive floods. At this location the channel is much too large to be seen ...

This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows gullies near the edge of Hale crater on southern Mars. The view covers an ...

The total distance driven by NASA's Mars rover Curiosity passed the one-mile mark a few days before the first anniversary of the rover's landing on Mars.

This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows the transition between the "Murray Formation," in which layers are poorly expressed and difficult to tra...

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 path on Mars of NASA's Curiosity rover toward Glenelg, an area where three terrains of scientific interest converge.

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...

NASA's Mars Exploration Rover Opportunity has been working on Mars since landing inside Eagle Crater on Jan. 25, 2004 (Universal Time; evening of Jan. 24, Pacific Standard Time).

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 December 8, 2018 by NASAs Mars Reconnaissance Orbiter, shows erosion of the surface revealing several shades of light toned layers, likely sedimentary deposits.
