"Hole" Lotta Grindin' Going On
The red marks in this image, taken by the Mars Exploration Rover Opportunity's panoramic camera, indicate holes made by the rover's rock abrasion tool, located on its instrument deployment device, or "arm." The lower hole, located on a target called "McKittrick," was made on the 30th martian day, or sol, of Opportunity's journey. The upper hole, located on a target called "Guadalupe" was made on sol 34 of the rover's mission. The mosaic image was taken using a blue filter at the "El Capitan" region of the Meridiani Planum, Mars, rock outcrop. The image, shown in a vertical-perspective map projection, consists of images acquired on sols 27, 29 and 30 of the rover's mission.
