Endeavour Crater Opportunity drove up to the west rim of Endeavour, a 22-kilometer (13.7 mile) diameter
crater, at Cape York, in August 2011. After finding signs of past water and ancient clay
minerals there, the robot field geologist roved on, and is currently in Cape Byron
conducting the first-ever study of an ancient geological feature that from orbit looks like it
was carved by water. The base image is a mosaic taken by the Malin Space Science
Systems’ Context Camera on the Mars Reconnaissance Orbiter. Larry Crumpler, of the
New Mexico Museum of Natural History & Science, provided the labeling. North is up. NASA / JPL-Caltech / MSSS / NMMNHS / L. Crumpler
