March: Victoria crater. - March: Victoria Crater at Meridiani Planum - View of the Victoria crater obtained by the HIRISE camera on board the Mars Reconnaissance orbiter probe. This crater is 800 meters in diameter. The opportunity rover reached this crater on September 27, 2006. After exploring about a quarter of the crater's edges, the rover descended almost a year later to begin an exploration of the crater's interior. Victoria Crater, about 800 meters (one - half mile) in diameter, has been home ground for Nasa's Mars Exploration Rover Opportunity for more 14 of the rover's first 46 months on Mars. Opportunity first reached the crater's rim on Sept. 27, 2006, during the 951st Martian day, or sol, of the rover's work in the Meridian Planum region of Mars. The rover then explored clockwise about one - fourth of the way around the rim before returning to a point close to its first overlook. On the mission's 1,293rd sol (Sept. 13, 2007), Opportunity began a sustained exploration of the interior of the crater, entering at an alcove called “” Duck Bay””” on the western side of Victoria.
