Over the years, NASA has sent five robotic vehicles, called rovers, to Mars. The names of the five rovers are: Sojourner, Spirit and Opportunity, Curiosity, and Perseverance.

The Mars Science Laboratory flight system will consist of four major elements in three distinct phases (from left): the cruise stage, the aeroshell (heatshield and backshell), the descent stage, an...

After an activity called the "mini drill test" by NASA's Mars rover Curiosity, the rover's Mars Hand Lens Imager (MAHLI) camera recorded this close-up view of the results during the 180th Martian d...

This graphic from NASA's Curiosity mission shows an analysis of the composition of two rocks called "Crest" and "Rapitan" in the "Yellowknife Bay" area of Mars.

This full-resolution image shows part of the deck of NASA's Curiosity rover taken from one of the rover's Navigation cameras looking toward the back left of the rover.

This image shows part of the small pit or bite created when NASA's Mars rover Curiosity collected its second scoop of Martian soil at a sandy patch called "Rocknest."

NASA's Curiosity Mars rover has caught the first image of asteroids taken from the surface of Mars.

This graphic shows proportions of minerals identified by the Curiosity Mars rover's CheMin instrument in mudstone outcrops at "Yellowknife Bay" in 2013 and at "Murray Buttes" in 2016. For example, ...

As NASA's Curiosity heads to Mount Sharp, the rover is using autonomous navigation to pick the best route.

In this image, a large, six-wheeled rover sits on a concrete floor in a laboratory against a light-blue background. The rover's 'legs,' or mobility system are a medium blue color and the large, cle...

NASA's Curiosity Mars rover used its Navigation Camera (Navcam) to capture this view on April 11, 2015, during the 952nd Martian day, or sol of the rover's work on Mars. The image appears three-dim...

Goal1: Determine whether life ever arose on Mars

A sweeping panorama combining 33 telephoto images into one Martian vista presents details of several types of terrain visible on Mount Sharp from a location along the route of NASA's Curiosity Mars...

This rectangular version of a self-portrait of NASA's Mars rover Curiosity combines dozens of exposures taken by the rover's Mars Hand Lens Imager (MAHLI) during the 177th Martian day, or sol, of ...

The reclosable dust cover on Curiosity's Mars Hand Lens Imager (MAHLI) was opened for the first time during the 33rd Martian day, or sol, of the rover's mission on Mars (Sept. 8, 2012), enabling MA...

Thick stacks of clay minerals indicate chemical alteration of thick stacks of rock by interaction with liquid water on ancient Mars.

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...

This is the first image taken by NASA's Curiosity rover, which landed on Mars the evening of Aug. 5 PDT (morning of Aug. 6 EDT).

As of June 2012, the target landing area for Curiosity, the rover of NASA's Mars Science Laboratory mission, is the ellipse marked on this image, about 12 miles long and 4 miles wide (20 kilometers...

This illustration provides a comparison for how big the moons of Mars appear to be, as seen from the surface of Mars, in relation to the size that Earth's moon appears to be when seen from the surf...

This map shows where NASA's Mars rover Curiosity landed in August 2012 at "Bradbury Landing"; the area where the rover worked from November 2012 through May 2013 at and near the "John Klein" target...

The graph at right presents information from the NASA Curiosity Mars rover's onboard analysis of rock powder drilled from the "Big Sky" and "Greenhorn" target locations, shown at left.

This illustration shows the locations and interactions of volatiles on Mars. Volatiles are molecules that readily evaporate, converting to their gaseous form, such as water and carbon dioxide.
