re: Opportunity heads up and out
There is a similar shot from the rear haz cams, but a later image shows them un 'burried' - so I imagine the same is true of the front wheels.
This is no more 'stuck' than half way thru a trenching operation. There is no doubt, however, that Oppy is in some difficult driving terrain. If they'll ever make it to 'Escape hatch' - I doubt it, they'll be going back out the way they came in imho.
