Oppy looks like to be stuck in a dune once more!

The front wheels (rover was moving backwards into the dune) look to be closer to solid surface than during the purgatory incident, so hopefully they can back out pretty quickly.

I know this is already being discussed in the other thread, but I think this way the incident is clearer to a casual reader of the forum. Threads of nearly 1000 posts clog the discussion anyway.
