Opportunity Pancam: Opportunity took her first tentative steps into Endurance Crater with
the intent of examining the exposed stratigraphy with the IDD (Instrument Deployment Device)
instruments. This image of the “RAT Nest” includes three holes drilled by the RAT
(Rock Abrasion Tool), on targets named CobbleHill, Virginia, and London. Differences
between spectral properties of the rock surfaces and the RAT hole dust are evident.
