Telling ‘tails’
Telling ‘tails’ At La Bajada, Opportunity used her Microscopic Imager (MI) to take these pictures of the erosional tails on Mesilla. These digital images are part of the final visual evidence that led MER scientists to the fundamental finding that these rocks have been etched by an erosional force, which, most on the team strongly theorize, is wind. As MER Deputy Principal Investigator Ray Arvidson put it: “We’ve nailed the fact that wind has modified the rocks on the centimeters to tens of centimeters scale." NASA / JPL-Caltech
