Opportunity: Landing

At a rock called "Clovis," the rock abrasion tool on Spirit cut a 9-millimeter (0.35-inch) hole. To the right of the drill hole is a "brush flower" of circles produced by scrubbing the surface of...

A section of the Mars Science Laboratory's Gale Crater landing site is shown, with a representative path from the landing location toward the layered mound to the south.

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.

NASA's Mars Exploration Rover Opportunity is continuing its traverse southward on the western rim of Endeavour Crater during the fall of 2014, stopping to investigate targets of scientific interest...

This image shows the rock dubbed "Humphrey" and the circular areas on the rock that were wiped off by the rover.

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.

This false-color image highlights mysterious and sparkly dust-like material that is created when the soil in this region is disturbed.

An elongated crater called "Spirit of St. Louis," with a rock spire in it, dominates a recent scene from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity.

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

Opportunity captured this vista of "Victoria Crater" from the viewpoint of "Cape Verde," one of the promontories that are part of the scalloped rim of the crater.

This mosaic was stitched together using images from the Navigation Camera, or Navcam, on NASA's Opportunity rover. The scene shows the rover's tracks made in Perseverance Valley between Sols 5,000 ...

The Pancam on NASA's Opportunity Mars rover imaged this small, relatively fresh crater in April 2017, during the 45th anniversary of the Apollo 16 mission to the moon. The rover team chose to call ...

This before-and-after pair of images of the same patch of ground in front of NASA's Mars Exploration Rover Opportunity 13 days apart documents the arrival of a bright rock onto the scene.

Donc, vous voulez étudier Mars avec un atterrisseur ou un rover, mais où l’envoyer exactement? Apprenez comment les scientifiques et ingénieurs abordent cette question dans cette vidéo de 60 second...

An artist's concept portrays a NASA Mars Exploration Rover on the surface of Mars. Two rovers have been built for 2003 launches and January 2004 arrival at two sites on Mars. Each rover has the mob...

This July 7, 2017, scene from the Navcam on NASA's Opportunity Mars rover shows a view from the upper end of "Perseverance Valley" on the inner slope of Endeavour Crater's rim. At left, the valley...

This grouping of two test rovers and a flight spare provides a graphic comparison of three generations of Mars rovers developed at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The setting is ...

"Marathon Valley" on Mars opens to a view across Endeavour Crater in this enhanced-color version of a scene from the Pancam of NASA's Mars Exploration Rover Opportunity. The scene merges many expos...

A portion of an exposure of bedrock dubbed "Larry's Outcrop" shows little layering in this view, in contrast to nearby outcrops called "Methuselah" and "Jibsheet."

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.

Researchers used NASA's Mars Exploration Rover Opportunity to find a water-related mineral on the ground that had been detected from orbit, and found it in the dark veneer of rocks on the rim of En...

This infographic highlights NASA’s twin robot geologists, the Mars Exploration Rovers (MER) Spirit and Opportunity.  The rovers landed on the Red Planet in 2004, in search of answers about the hist...

JPLers pounded the pavement in celebration of a Mars marathon milestone. Opportunity rover took 11 years and 2 months to clock 26.2 miles. The team's time was considerably less.

In this selfie, Spirit shows her solar panels gleaming in the Martian sunlight and carrying only a thin veneer of dust two years after the rover landed and began exploring the red planet.
