OPP-SOL943-B_P2382_R2-B943R1-1.jpgOnly 50 meters away... (1) - Sol 94353 visiteCaption NASA originale:"A drive of about 60 mt (approx. 200 feet) on the 943rd Sol, of Opportunity's exploration of Mars' Meridiani Planum Region (such as Sept. 18, 2006) brought the NASA Rover to within about 50 mt (approx. 160 feet) of the rim of Victoria Crater.
This crater has been the mission's long-term destination for the past 21 Earth months. Opportunity reached a location from which the cameras on top of the Rover's mast could begin to see into the interior of Victoria.
This frame was taken on Sol 943 by the PanCam and it shows the upper portion of interior crater walls facing toward Opportunity from up to about 850 mt (half a mile) away. The amount of vertical relief visible at the top of the interior walls from this angle is about 15 mt (roughly 50 feet). The exposure was taken through a PanCam filter selecting wavelengths centered on 750 nanometers".

OPP-SOL943-B_P2382_R2-B943R1-2.jpgOnly 50 meters away... (2) - Sol 94353 visiteCaption NASA originale:"Victoria Crater is about five times wider than Endurance Crater - which Opportunity spent six months examining in 2004 - and about 40 times wider than Eagle Crater, where Opportunity first landed. The great lure of Victoria is the expectation that a thick stack of geological layers will be exposed in the crater walls, potentially several times the thickness that was previously studied at Endurance and therefore, potentially preserving several times the historical record".

OPP-SOL943-Opp_Vic_Approach_Ncam_labels-B951R1.jpgVictoria Crater (labeled) - Sol 94362 visiteOnce it was more like a distant dream, the ultimate bonus to an already marvelous Martian mission. Now, NASA's Mars Exploration Rover Opportunity is on the brink of the expansive "Victoria Crater," a depression that truly makes those on the path to it look like dimples. At about 800 meters (nearly half-a-mile) in diameter, Victoria is five times larger then "Endurance Crater."
This image from Opportunity's navigation camera is labeled to highlight features of the large crater. Victoria Crater is informally named for the flagship of Ferdinand Magellan's 16th-Century expedition around the world, and many the features of Victoria will be informally named for places visited by that expedition.
The feature labeled in dark yellow as "Bright Crater" is another crater just outside the far rim of Victoria. At 30 to 40 meters (98 to 131 feet) in diameter, the depression is larger than Opportunity's landing site, "Eagle Crater." Labeled in bright purple is "Duck Crater," a small dimple on the near side of Victoria Crater (the name is used as a placeholder until the team decides if it will name it or not). Other distant craters are labeled in bright blue.
On the far right of the image is "Kitty Clyde's Sister," a highly degraded crater informally named for a boat in John Wesley Powell's 19th-Century expedition through the Grand Canyon.
The science and engineering teams are strategizing on the best way to approach, and possibly enter, Victoria Crater.
