This scene from the panoramic camera (Pancam) of NASA's Mars Exploration Rover Opportunity catches "Pillinger Point," on the western rim of Endeavour Crater, in the foreground. The eastern rim of the crater is on the distant horizon. Endeavour Crater is 14 miles (22 kilometers) in diameter.
Opportunity's international science team chose Pillinger Point as the informal name for this ridge as a tribute to Colin Pillinger (1943-2014). Pillinger was the British principal investigator for the Beagle 2 project, which attempted to set a lander on Mars a few weeks before Opportunity's January 2004 landing.
The site became a destination for Opportunity to examine because observations from orbit indicated the presence of a clay mineral named montmorillonite, which forms under wet conditions.
