Dawn's looping round the north side now, so the 'where is Dawn' page is showing an illuminated crescent:
http://neo.jpl.nasa.gov/orbits/fullview4.jpg (presumably that links to the current image, when you link to it, not the version I am looking at now) Enough of the surface is visible to see that the texture map currently in use is really from Tethys! Penelope and the chain of craters to its west are visible right now. Phil -------------------- ... because the Solar System ain't gonna map itself.
