Opportunity spotted Exploring vast Endeavour Crater from Mars Orbit

Opportunity captured at Endeavour Crater rim on Sept 10, 2011, Sol 2712
Opportunity is visible at the end of the white arrow, sitting atop some light toned outcrops on the rim of Endeavour Crater located at the southern tip of a rim segment named Cape York. Opportunity is ascending Endeavour at Cape York ridge and positioned to the right of the small crater named Odyssey. This image was taken by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter (MRO), Opportunity travelled nearly three years to reach this rim because it contains rocks even more ancient than the rocks of Meridiani Planum, which the rover has been exploring since 2004, and hence may teach us something about an even more ancient era in Martian history.

Opportunity has just been imaged in high resolution at Endeavour crater by a powerful NASA camera orbiting overhead in Mars orbit. The new image (see above) was snapped while NASA’s long lived robot was climbing a hilltop offering spectacular panoramic vistas peering into the vast crater which is some 14 miles (22 km) wide.

Look very closely and you’ll even be able to easily discern the rovers pair of tire tracks showing the path traversed by the robot as she explores the crater and the ejecta rocks and boulders excavated and strewn about by an ancient impact.

Opportunity is ascending up the rim of Endeavour crater at the southern tip of a low ridge dubbed Cape York – a location that has already yielded a bonanza of new science datasince her recent arrival in August 2011 after a more than 20 mile (33 km) epic trek.
The intrepid rover discovered a rock unlike any other since she safely landed at the Meridiani Planum region of Mars nearly eight years ago on Jan. 24, 2004.
Opportunity is now searching Endeavour crater and Cape York for signatures of phyllosilicates – clay minerals that formed in the presence of pH neutral water flowing on Mars surface billions of years ago.

Opportunity arrived at the rim of Endeavour on Sol 2681, August 9, 2011 and climbed up the ridge known as Cape York. Odyssey crater is visible at left. Opportunity has since driven a short distance beyond Odyssey crater and was photographed from Mars orbit on Sept. 10, 2011.
