Pasadena CA (JPL) Oct 10, 2006 NASA's Mars Exploration Rover Opportunity reached the rim of "Victoria Crater" on Sept. 27, 2006, during the 951st Martian day, or sol, of the rover's work in the Meridian Planum region of Mars. Opportunity drove 9.28 kilometers (5.77 miles) in the explorations that took it from "Eagle Crater," where it landed in January 2004, eastward to "Endurance Crater," which it investigated for about half of 2004, then southward to Victoria. This map of Opportunity's trek so far is overlaid onto images taken by the Mars Orbiter Camera on NASA's Mars Global Surveyor. Victoria is about 800 meters (one-half mile) in diameter, or about five times wider than Endurance and 40 times wider than Eagle. The scale bar at lower right shows the length of 800 meters (0.50 mile). North is up. The following gives the Earth date for the sol number on the image at right: Sol 58 was Mar. 24, 2004
Sol 315 was Dec. 12, 2004 Sol 446 was Apr. 26, 2005 Sol 654 was Nov. 25, 2005 Sol 833 was May 28, 2006 Sol 898 was Aug. 3, 2006 Sol 952 was Sept. 28, 2006
 This view of "Victoria crater" (above) is looking southeast from "Duck Bay" towards the dramatic promontory called "Cabo Frio." The small crater in the right foreground, informally known as "Sputnik", is about 20 meters (about 65 feet) away from the rover, the tip of the spectacular, layered, Cabo Frio promontory itself is about 200 meters (about 650 feet) away from the rover, and the exposed rock layers are about 15 meters (about 50 feet) tall. This is an approximately true color rendering of images taken by the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity during the rover's 952nd sol, or Martian day, (Sept. 28, 2006) using the camera's 750-nanometer, 530-nanometer and 430-nanometer filters.
