Steve Squyres, principal investigator for NASA’s Mars Exploration Rover mission, and Matt Golombek, the mission’s project scientist, discussed the ground-breaking science returned by the mission’s ...

This view from NASA's Opportunity Mars rover shows part of "Marathon Valley," a destination on the western rim of Endeavour Crater, as seen from an overlook north of the valley. It was taken by the...

This false-color view from NASA's Mars Exploration Rover Opportunity shows "Lunokhod 2 Crater," which lies south of Solander Point on the west rim of Endeavour Crater.

Artist's concept of rover using the rock abrasion tool (RAT) on the robotic arm grinds away the rock's surface, allowing scientific instruments to analyze the rock's interior.

The "Columbia Hills" flank Spirit's path in this view.

As NASA's Mars Exploration Rover Opportunity creeps farther into "Endurance Crater," the dune field on the crater floor appears even more dramatic

Two spacecraft engineers stand with a group of vehicles providing a comparison of three generations of Mars rovers developed at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The setting is JPL...

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...

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.

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.

This full-circle panorama shows the terrain around the NASA Mars Exploration Rover Opportunity during the 3,071st Martian day, or sol, of the rover's work on Mars (Sept. 13, 2012).

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.

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...

In the Payload Hazardous Servicing Facility, an overhead crane lowers the Mars Exploration Rover (MER) aeroshell toward a rotation stand.

Cindy Oda stood up to share her experience working with NASA’s Opportunity rover during a team meeting in Mission Control at NASA’s Jet Propulsion Laboratory in Pasadena, California.

This stereo scene from NASA's Mars Exploration Rover Opportunity shows part of "Marathon Valley," a destination on the western rim of Endeavour Crater, as seen from an overlook north of the valley.

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."

This image from the Mars Exploration Rover Opportunity's panoramic camera is an approximate true-color rendering of the exceptional rock called "Berry Bowl" in the "Eagle Crater" outcrop.

This color view of a mineral vein called "Homestake" comes from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity.

"Marathon Valley" on Mars opens northeastward in this stereo version of a scene from the Pancam of NASA's Mars Exploration Rover Opportunity. The scene, recorded in April and May 2016, appears thre...

Near the lower left corner of this view is the three-petal lander platform that NASA's Mars Exploration Rover Spirit drove off in January 2004.

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

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 ...

Landing a spacecraft on Mars is one of the trickiest things we do. This 60-second video explains how it's done, and the three landing systems we use at the Red Planet.
