Victoria Crater
|
Caption NASA originale:"After driving more than 9 Km (about 5,6 miles) from the site where it landed in January 2004, NASA's MER Opportunity approached "Victoria Crater" in September 2006. The crater is about 750 mt (a little less than half a mile) across.
That is about six times wider than "Endurance Crater" where Opportunity spent six months examining in 2004, and about 35 times wider than "Eagle Crater" where Opportunity first landed. The walls of Victoria hold the scientific allure of much taller stacks of geological layers -- providing the record of a longer span of the area's environmental history -- than Opportunity has been able to inspect on the Meridiani plains or at smaller craters.
This image created by the U.S. Geological Survey uses a digital elevation model generated from computer analysis of three images taken by the Mars Orbiter Camera aboard NASA's Mars Global Surveyor orbiter. The vertical dimension is not exaggerated relative to the horizontal dimensions. The crater is about 70 mt (230 feet) deep.
The images used for providing the stereo information to calculate relative elevation were taken on Feb. 1, 2004 (http://www.msss.com/moc_gallery/r10_r15/images/R14/R1401689.html) and April 16, 2005 (http://www.msss.com/moc_gallery/s05_s10/images/S05/S0500863.html).
Opportunity is approaching Victoria from North-West".
