OPP-SOL901-PIA08753-001.jpgBeagle Crater and 360° Panorama from Sol 901 through 904 (1)53 visiteCaption NASA originale:"This 360° view shows one of Opportunity's last stops on the now-familiar surface of Meridiani Planum before reaching different terrains associated with the very large Victoria Crater. In the center of the mosaic - frames 7 to 11 - is Beagle Crater, an impact crater about 35 mt (115 feet) wide. On the far left and wrapping around to the far right, Opportunity's tracks are visible approaching the crater".

OPP-SOL901-PIA08753-002.jpgBeagle Crater and 360° Panorama from Sol 901 through 904 (2)53 visiteCaption NASA originale:"Though it looks relatively fresh in orbital images, from a closer vantage point Beagle Crater appears moderately eroded.
The crater walls are slumped and the middle of the crater bowl is filled with rippled sand. However, a slightly raised crater rim remains, and in a few places (for instance, on the inside left wall), cliffs of outcrop appear to be preserved in the crater. Ejected rocks from Beagle Crater surround the Rover, many with the distinctive, fine-grained layering commonly seen in the rocks of Meridiani Planum. Many of these rocks have surfaces smoothed by wind erosion. Wind erosion also formed the sand drifts nestled among the rocks".

OPP-SOL901-PIA08753-003.jpgBeagle Crater and 360° Panorama from Sol 901 through 904 (3)53 visiteCaption NASA originale:"Because impact craters have well-understood shapes when they form, the altered appearance of eroded craters gives scientists clues to the processes that modified them. By observing how filled an impact crater has become and how worn its edges are, scientists can estimate how long its surface has been exposed to erosion. The many-sided outline of a crater such as Beagle and the blocky appearance of its ejecta may also tell scientists about the strength of the underlying bedrock. Based on observations such as these, scientists know that Beagle Crater is fresher than Eagle and Fram craters near Opportunity's Landing Site and more similar in form to Viking and Voyager craters in the plains to the North of Beagle".

OPP-SOL901-PIA08753-004.jpgBeagle Crater and 360° Panorama from Sol 901 through 904 (4)53 visiteCaption NASA originale:"Opportunity made other observations at Beagle Crater, such as spectroscopic measurements taken with the PanCam and the Miniature Thermal Emission Spectrometer, to help scientists assess the composition of the rocks and determine whether Beagle Crater was excavated into the surface rocks of Meridiani Planum or into the ejecta blanket of Victoria Crater".

OPP-SOL901-PIA08753-005.jpgBeagle Crater and 360° Panorama from Sol 901 through 904 (5)56 visiteCaption NASA originale:"Beagle Crater takes its unofficial name from a great ship of exploration, the HMS Beagle, whose most famous passenger was British naturalist Charles Darwin. During the Beagle expedition around the world, Darwin conducted many of the observations that led to his theory of natural selection. Scientists have unofficially named many rocks and features in the area of Beagle Crater after the Galapagos Islands and the varieties of finches Darwin observed there. The name Beagle Crater also commemorates the ill-fated British lander, Beagle 2, reminding us how difficult space exploration can be".

OPP-SOL901-PIA08753-006.jpgBeagle Crater and 360° Panorama from Sol 901 through 904 (6)53 visiteCaption NASA originale:"Opportunity took the mosaic of images that make up this 360-degree view of the Rover's surroundings with the Panoramic Camera (PanCam) on the Rover's 901st through 904th Soles, or Martian days (such as from Aug. 6 through Aug. 9, 2006), of exploration. This is an approximate true-color image combining exposures taken through the PanCam's 753-, 535- and 432-nanometer filters".
