Gagarin Rock - Sol 405 (Approx. True Colors; credits for the additional process. and color.: NASA/JPL-Caltech/Cornell Univ./ASU)

Caption NASA:"NASA's Mars Exploration Rover Opportunity used its Rock Abrasion Tool on a rock informally named "Gagarin" during the 401st and 402nd Martian Days, or Soles, of the rover's work on Mars (such as March 10 and 11, 2005).

This image shows the Circular Mark created where the tool exposed the interior of the rock Gagarin at a target called "Yuri". The circle is about 4,5 cm (1,8") in diameter. Gagarin is at the edge of a highly eroded, small crater that was informally named "Vostok" (after the Spacecraft that carried Cosmonaut Yuri Gagarin in the first human spaceflight, on April 12, 1961).

This image combines exposures taken through three different filters by Opportunity's PanCam (PanCam) on Sol 405 (March 14, 2005). The view is presented in Approximately True Color".
