NASA's Mars Exploration Rover Opportunity has found a rock that apparently is another meteorite. Dubbed "Shelter Island," the meteorite is about 18.5 inches (47 centimeters) long.
This view of a rock called "Block Island," the largest meteorite yet found on Mars, comes from the panoramic camera (Pancam) on NASA's rover Opportunity. This is a false-color, red-green-blue composite view generated from images taken through the Pancam's
Bizarre Block Triangle
The triangular pattern of small ridges seen at the upper right in this image and elsewhere on the Mars meteorite "Block Island" is characteristic of iron-nickel meteorites found on Earth, especially after they have been cut, polished and etched.
Opportunity's Route to Endeavour Crater
After a three-year drive, the Mars Exploration Rover Opportunity reached the Endeavour crater, a 14 mile crater formed by bombardment early in the life of the solar system. The map traces the route through the 2,670th Martian day, or sol, of Opportunity's work on Mars (July 29, 2011).
Opportunity's Southward View of 'McClure-Beverlin Escarpment' on Mars
The boulder-studded ridge in this scene recorded by NASA's Mars Exploration Rover Opportunity is "McClure-Beverlin Escarpment." This view toward the south is a mosaic of images taken by Opportunity's panoramic camera (Pancam) on Dec. 25, 2013.
Where Martian 'Jelly Doughnut' Rock Came From
This image from the panoramic camera on NASA’s Mars Exploration Rover Opportunity shows where a rock called "Pinnacle Island" had been before it appeared in front of the rover in early January 2014. This image was taken on Feb. 4, 2014.
