Mars Exploration Rover Instrument Diagrams

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...

These images of a sand "ripple" were acquired by Opportunity using its panoramic camera on sol 644 and its navigation camera on sol 645.

This view from within "Perseverance Valley," on the rim of Endurance Crater, includes wheel tracks from the Opportunity Mars rover's descent of the valley to investigate its origin. The rover's Pan...

The Mars Exploration Rover-2 is moved to a workstand in the Payload Hazardous Servicing Facility.

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...

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...

Since landing on Mars a year ago, NASA's pair of six-wheeled geologists have been constantly exposed to martian winds and dust.

Spirit discovered this remarkable patch of bright, loose soil while driving toward "Home Plate" along the floor of the basin south of "Husband Hill" in Gusev Crater.

Members of the Mars Exploration Rover Mission's Entry, Descent and Landing team rejoice at the news that mission control received its first signal from Spirit, indicating the rove...

NASA's Mars Exploration Rover Spirit obtained this stereo panorama of the surrounding Martian terrain in Gusev Crater from two positions about 10 meters (33 feet) apart. This is much greater separa...

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

This self-portrait from Opportunity shows dust accumulation on the rover's solar panels as the mission approached its fifth Martian winter.

What looks like the rover "neck and head" is called the Pancam Mast Assembly.
