According to Dawn (who ought to know) the descent to the next mapping orbit is beginning now.
"NASA_Dawn NASA's Dawn Mission I'm done with Survey science operations today!! Time for a several-week transfer down to High Altitude Mapping Orbit (HAMO)!! 20 hours ago" Better pics on the way! Thanks, Dawn team, for the pictures so far. Will we learn of any preliminary nomenclature soon? Phil -------------------- ... because the Solar System ain't gonna map itself.

And today picture resized 400% and gamma corection for "best look" From TIFF. Source: http://photojournal.jpl.nasa.gov/catalog/PIA14698 http://dawn.jpl.nasa.gov/multimedia/imageo...p?date=20110911 This picture is starting to show some very fine surface detail and texture. I can see why the science pros are tossing out some of their early hypotheses. There is more than enough weird stuff not like anything else seen to make me want to shut up theorizing until I've had a closer look. Some of the topics for thought on the shaping of Vesta... Extreme seismic phenomenon from South Pole impact. Contributor to Equatorial grooves? To smaller terrain shapes? Extreme-but-transient electromagnetic phenomenon. (Impact, CME?) Large structurally detailed albedo features relatively independent of surface terrain. Impacts of globs of stuff? Exposed dike/craton forms? Ring collapse onto wobbly Vesta? Unlikely, with many ridge-groove areas non-great-circle. But if the impact sent out heavily-"rayed" debris, could it produce the right terrain on fast-rotating Vesta? So many questions. More than before Dawn arrived... |
