After 10 years on Mars, rover Opportunity makes big water find

4. So I guess the rover does wheelies in it's sleep.

There are no tracks, no disturbance in any direction around it. I wolud think it would have to be very light to have gotten there without any disturbance. It also has multiple layers it seems, like the white surface partly showing. I think it's likely some insulation or impact material that was stuck on one of the arms out of camera view since the landing and finally blew off during the long winter sleep. It probably hit the ground very lightly and... there is is. That would mean it will likely blow away in one of then next big winds. But pushed there by the wheels doesn't explain a lot of other surrounding features. That's my 2 cents.

Oh... not to forget the point of the OP... I really exited that Opportunity is still cranking out great new data. The confirmation of the existence of water is just about the holy grail of any mars mission so far.
