It's been an awful long time since we've seen one of these from Spirit:
It's an animation of four Navcam frames documenting motion on Spirit! It looks like they are getting ready to test some of the extrication procedures they've spent the last few months developing. Before you get too excited about the motion, I should mention what rover driver Scott Maxwell said via Twitter yesterday, which was that this motion was just to steer the wheels into position for a future drive. Even so, it's a thrill to see Spirit doing anything like roving again.
Here's an absurd number of perspectives on the motion. First, the forward hazcam. This is actually looking backward along the path Spirit took into her current trap. The right front wheel (which Spirit must drag behind her as she moves) did not move; the left front wheel straightened.
Two different perspectives from the rear hazcams, left and right. It's hard to even see the wheels in either of these, they're so buried.
