6th Year Anniversary Graphic

Details of the Gusev Crater designated landing site are added with topographic information and higher-resolution imaging from instruments on the Mars Global Surveyor and Mars Odyssey orbiters.

The left image shows an extreme close-up of round, blueberry-shaped formations in the martian soil near a part of the rock outcrop at Meridiani Planum called Stone Mountain.

NASA's Opportunity rover celebrates 8th anniversary on Mars.

A self-portrait of NASA's Mars Exploration Rover Opportunity taken by the rover's panoramic camera (Pancam) shows effects of recent winds removing much of the dust from the solar arrays.

This Martian scene shows contrasting textures and colors of "Hinners Point," at the northern edge of "Marathon Valley," and swirling reddish zones on the valley floor to the left.

This image is a cropped version of the last 360-degree panorama taken by the Opportunity rover's Panoramic Camera (Pancam) from May 13 through June 10, 2018. The view is presented in false color to...

This false color image suggests that the plains beyond the small crater where the Mars Exploration Rover Opportunity now sits are littered with the same dark grey material found inside the crater i...

Entry, descent and landing manager, Rob Manning (facing camera), hugs Richard Cook, the current Mars Exploration Rover project manager after Opportunity's successful landing at Meridiani Planum, Mars.

Dr. Wayne Lee, chief engineer for development of the Mars Exploration Rover's descent and landing systems proudly waves a broom, indicating a clean martian sweep.

NASA's InSight arrives at Vandenberg AFB and readies for launch, Opportunity uses its abrasion tool for the first time in 300 sols, and Curiosity celebrates 2,000 Martian days on the Red Planet.

Opportunity used its panoramic camera to record this eastward horizon view on the 2,407th Martian day, or sol, of the rover's work on Mars (October 31, 2010).

This stunning image mosaic of the "Columbia Hills" is the first 360-degree panorama taken by Spirit after arriving at the hills.

Researchers used the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity to capture this 10-second-exposure view of comet C/2013 A1 Siding Spring as it passed near Mars on Oct. 1...

This stereo view from the navigation camera on NASA's Mars Exploration Rover Opportunity shows a vista across Endeavour Crater, with the rover's own shadow in the foreground. The view spans 216 com...

Dr. Steve Squyres, principal investigator for the science instruments on both Mars Exploration Rovers, celebrates as the team witnesses the first images sent back from Spirit.

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.

Opportunity captured this view of "Burns Cliff" after driving right to the base of this southeastern portion of the inner wall of "Endurance Crater."

John Callas has been a leader of NASA's Mars Exploration Rover Project since the project's inception in 2000, and has been the project manager since 2006.

This image highlights the bumpy terrain surrounding the rover.

Results from Opportunity and Curiosity show Mars could have supported life.
