Small rock like pyramid - Contact Target for Curiosity

The drive by NASA's Mars rover Curiosity during the mission's 43rd Martian day (Sept. 19, 2012) ended with this rock about 8 feet (2.5 meters) in front of the rover. The rock is about 10 inches (25 centimeters) tall and 16 inches (40 centimeters) wide. The rover team has assessed it as a suitable target for the first use of Curiosity's contact instruments on a rock. The image was taken by the left Navigation camera (Navcam) at the end of the drive. 

The rock has been named "Jake Matijevic." This commemorates Jacob Matijevic (1947-2012), who was the surface operations systems chief engineer for the Mars Science Laboratory Project and the project's Curiosity rover.
