This mosaic was acquired by the Mars Exploration Rover Opportunity’s Panoramic Camera (Pancam) on Sol 2793 (Dec. 2, 2011). It shows a north-facing outcrop, informally named “Greeley Haven,” where Opportunity will work during the rover’s fifth Martian winter.
The site is of interest not only for its geologic features but because it has favorable northerly slopes to optimize Opportunity’s solar energy as winter approaches in the southern hemisphere of Mars. After this mosaic was acquired, Opportunity backed up the slope to park at approximately 16 degrees northerly tilt and used tools on its robotic arm (Instrument Deployment Device, or IDD) to examine rock and soil targets. After deciding that the site could serve the mission well for the next several months, the team designated it as a memorial for Greeley, who taught generations of planetary scientists at Arizona State University, Tempe, until his death on Oct. 27, 2011.
