Countdown Nears: Final Tests

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...

Northern Hemisphere Gullies on West-Facing Crater Slope, Mars

This image from NASA's Mars Reconnaissance Orbiter (MRO) shows sand dunes on the slopes of Nectaris Montes within Coprates Chasma.

This map shows the route driven by NASA's Mars rover Curiosity through the 43rd Martian day, or sol, of the rover's mission on Mars (Sept. 19, 2012).

This animation flips back and forth between views taken in 2010 and 2014 of a Martian sand dune at the edge of Mount Sharp, documenting dune activity. The images are from the HiRISE camera on NASA'...

NASA’s Perseverance Mars rover and Ingenuity helicopter were spotted on the surface of the Red Planet in this black-and-white image captured Feb. 26, 2022, by the HiRISE camera aboard NASA’s Mars R...

In this Mars Reconnaissance Orbiter view of the Curiosity rover mission's waypoint called "the Kimberley," the red dot indicates the location of a sandstone target, "Windjana," selected for close-u...

This meteoroid impact crater on Mars was discovered using the black-and-white Context Camera aboard NASA’s Mars Reconnaissance Orbiter. The Context Camera took this image of the impact, which occur...

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 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.

Artist's concept of Mars Reconnaissance Orbiter near Mars.

Lyot 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.

Mars Reconnaissance Orbiter captures the springtime thaw of seasonal carbon dioxide ice on Mars.

In this HiRISE image taken within Capri Chasma, TES also detected the same crystalline gray hematite like that found at Meridiani Planum.

This image shows NASA's Mars Exploration Rover Opportunity perched on the edge of "Concepción" crater in Meridiani Planum, Mars.

A lunar eclipse, a solar eclipse and Mars has a close encounter with a comet.

This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows a mesa within the "Murray Buttes" area on Mars showing a complex fracture pattern (black arrow) protrudi...

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

This image from NASA's Mars Reconnaissance Orbiter shows many new ice blocks compared to earlier images in 2006. One of the most actively changing areas on Mars are the steep edges of the North Pol...

This picture was taken during the Martian summer with only small patches of ice remaining at the surface; they show up as bright, somewhat blue, spots on slopes that provide some shading from the Sun.

NASA's Mars Reconnaissance Orbiter arrived at Mars on March 10, 2006. Over the past decade, the mission has shown how dynamic Mars remains today, as well as how diverse its past environmental condi...

This image captures a fairly rare situation. In general, as lava flows along, it fills in low points and holes it encounters in its path and flows around high points such as hills and ridges. In th...

Eridania Basin Light-Toned Outcrops

This map indicates some of the geological information gained from orbital observations of Endeavour Crater, which has been the long-term destination for NASA's Mars Exploration Rover Opportunity si...

This is a close-up of the area in the vicinity of the Pathfinder landing site. Major features are named. The white box outlines the area of the image, where hardware is seen.
