| DESCRIPTION |
The Mars Exploration Rover Opportunity (MER 1) Rock Abrasion Tool (RAT) was an integral part of the Athena Science payload; it was produced to act as the payload's geologic hammer and more. The RAT exposed fresh surfaces of martian rocks to other instruments on the payload. The RAT also brushed dust and debris from an excavated hole or an unaltered rock target in addition to its rock hammer equivalency role. To accomplish these tasks, the RAT was a sophisticated 3-axis precision-controlled device that allowed it to also act as a rock physical properties science instrument. The returned RAT data was inverted and compared to a library of Earth rocks.
