Suspended by an overhead crane in the Payload Hazardous Servicing Facility, the Mars Exploration Rover (MER) aeroshell is guided by workers as it moves to a rotation stand.

This image shows segments of the western rim of Mars' Endeavour Crater. NASA's Mars rover Opportunity has explored parts of the rim since 2011. The view covers an area about 9 miles wide. It was ta...

NASA's twin robot geologists, the Mars Exploration Rovers, will launch toward Mars in 2003 in search of answers about the history of water on Mars.

This June 2017 view from the Pancam on NASA's Opportunity Mars rover shows the area just above "Perseverance Valley" on a large crater's rim. A broad notch in the crest of the rim, at right, mig...

A grooved ridge called "Rocheport" on the rim of Mars' Endeavour Crater spans this scene from the Pancam on NASA's Mars rover Opportunity. The view extends from south-southeast on the left to north...

While driving eastward toward the northwestern flank of "McCool Hill," Spirit's wheels churned up the largest amount of bright soil discovered to that point in the mission. This image from Spirit's...
