Opportunity Backshell and Parachute located
These appear to be visible in the latest Navcam images.
Look at the left hand side, just below the horizon. There is a large ovoid object and next to it a white patch.
Having thought for a while about the opportunity to visit the discarded heatshield which struck the crater rim near "Spirit", it would probably be far more sensible to locate Opportunity's heatshield and examine it, since it should be much easier to access in the excellent terrain around Opportunity Crater.
