Humphrey on the Inside

NASA's Mars Exploration Rover 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 (Oct. 31, 2010).

During four months prior to the fourth anniversary of its landing on Mars, Opportunity examined rocks inside an alcove called "Duck Bay" in the western portion of Victoria Crater.

This 360-degree panorama was taken by "Dusty," a fully-working replica of NASA's Opportunity rover at the agency's Jet Propulsion Laboratory. The panorama was taken as part of a software test. Memb...

NASA's Mars Exploration Rover Spirit has this view northward from the position at the north edge of the "Home Plate" plateau where the rover will spend its third Martian winter.

This global map of Mars shows a growing dust storm as of June 6, 2018. The map was produced by the Mars Color Imager (MARCI) camera on NASA's Mars Reconnaissance Orbiter spacecraft.

Composition measurements by NASA's Mars Exploration Rover Opportunity confirm that this rock on the Martian surface is an iron-nickel meteorite.

This enhanced-color view of ground sloping downward to the right in "Perseverance Valley" shows textures that may be due to abrasion by wind-driven sand. The Pancam on NASA's Mars rover Opportunity...

This Sept. 21, 2016, scene from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity shows "Spirit Mound" overlooking the floor of Endeavour Crater. The mound stands near the ...

This map updates progress that NASA's Mars Exploration Rover Opportunity is making toward reaching a driving distance equivalent to a marathon footrace. It indicates the rover position on March 5, ...

NASA's Mars Exploration Rover Opportunity observed this outcrop on the "Murray Ridge" portion of the rim of Endeavour Crater as the rover approached the 10th anniversary of its landing on Mars.

Researchers used the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity to capture this view of comet C/2013 A1 Siding Spring as it passed near Mars on Oct. 19, 2014.

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.

On the horizon in the right half of this panoramic view is an area of Mars informally named "Matijevic Hill," in commemoration of an influential rover-team leader.

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).

The flat-faced rock near the center of this image is a target for contact investigation by NASA's Mars Exploration Rover Opportunity in early March 2015.

NASA's Mars Exploration Rover Opportunity used its navigation camera to take the images combined into this stereo view of the rover's surroundings on the 958th sol, or Martian day, of its surface m...

As Opportunity crept farther into "Endurance Crater," the dune field on the crater floor appears even more dramatic, as seen in this false-color image.

This artist's concept animation depicts key events in NASA's Mars Exploration Rover mission, including launch; cruise; entry, descent & landing; egress; and, surface operations.

This vista of the Endeavour Crater rim was acquired by NASA's Mars Exploration Rover Opportunity's panoramic camera on April 18, 2014, from "Murray Ridge" on the western rim of the crater. It is pr...

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...

See how the scientists and engineers on Earth stretch their imaginations to design the best rover system to deal with the unpredictable dangerous terrain on Mars. Rover team members at Jet Propulsi...

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.

On Earth, a fast runner takes a few hours to complete a marathon. On Mars, it's taken 11 years. NASA's Opportunity rover crossed that finish line in 2015.

NASA's Mars Exploration Rover Opportunity recorded the component images for this self-portrait about three weeks before completing a decade of work on Mars.
