The view of July is finally giving us a view of unexplored terrain, just prior to the close encounter of september 2007. Really looking forward to that. Yeah, that area was imaged in August 2004, but from so far away (10 million kilometres) that the only details visible were the basic outline of the Roncevaux Terra basin, and its central peak. So, although we *have* seen it, it's effectively unexplored. The LPSC 2005 abstract by Denk et. al., "The first six months of Iapetus observations by the Cassini ISS camera", shows processed versions of these images. It's online and is easily located with a Google search. (Don't bother checking the raw images from August 2004 -- you can't see anything in those.) This gives a good idea of the size of that basin. It's about the same size as the huge one on the Saturn-facing side. |
