The rover had completed a short drive just before taking the second image, and one of its wheels likely knocked the rock — dubbed “Pinnacle Island” — to this position. The rock is about the size of a doughnut.The images are from Opportunity’s panoramic camera (Pancam). The one on the left is from 3,528th Martian day, or sol, of the rover’s work on Mars (Dec. 26, 2013). The one on the right, with the newly arrived rock, is from Sol 3540 (Jan. 8, 2014). Much of the rock is bright-toned, nearly white. A portion is deep red in color. Pinnacle Island may have been flipped upside down when a wheel dislodged it, providing an unusual circumstance for examining the underside of a Martian rock.The site is on “Murray Ridge,” a section of the rim of Endeavour Crater where Opportunity is working on north-facing slopes during the rover’s sixth Martian winter.For more information visit http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA17761.
