Stuff from the rovers
Images from the rovers (I used links instead of images just for you, Tom)
1. Layered rock from Spirit - looks like the cameras are still working, at least!
2. Interesting formations from Opportunity - how big are those globular formations that look like coral heads?
I think they just got missed in this collage: If the dune area is about 30 m long and 20 wide, I would guess the "apron" area in the "coral" image is about 10 m across, and the rover about 10 m away from it, making the "coral" 5 m away and something like a meter high?
