re: Gullies, the MRO way! (1.7 MB)
The gullies are fascinating, but so is that black and white image of the overall crater. I think it's almost getting overlooked. They said at the press conference that it was twenty times larger than Victoria. Hopefully they'll come out with a color version later. It'd be interesting to see if one of the guys over at unmannedspaceflight.com could create an image showing Victoria inside of Terra Sirenun.
