Well - impactor TCM 1 went well - <0.3% error and it's on course for a nominal impact time. PI has suggested that the comet is Banana shaped and we're going to hit the end of it which looks a little triangular

1600GMT Press Conf Highlights
 Web Hits : Last 24 hrs 1 billion hits. 2.5X that of busiest day for MER Flyby Spacecraft in Great Shape - amazing picture post-shield mode, plume looks as large as the whole comet Pre-Release targetting was a few km off to the left. Post ITM1 was way below the comet, Post ITM2 was just left of centre, and ITM3 just below and to the right of it. New result : Map of temp of the Neuc pre-impact. Sub-solar part is warmest (obviously) Ejecta/Outgassing coming out for several hours after impact. Lots of topographic relief - things that really do look like impact craters. Bright spots, mostly just steep sun-facing slopes - a couple are not. Almost certainly there is layering, jets coming from somewhere they hope to trace Two circular features were refered to as craters Sequence of videos - shadow caused by ejecta Processed HRI imagery movie of impact - not THAT much better than the MRI movie Height of ejecta on lookback image (at about 27,000km) 1000's of Km's height to ejecta. Mainly dust Not 100% sure if they can actually see the crater - they have a 'feature' that may be the crater. Approx 160kg useable fuel onboard flyby. Do not have specific extended mission plan currently, will probably mothball the spacecraft in a few weeks. (I assume to pick it up again in the future) Further simualted impacts at the ames canon. 'Dual-ish' plume, i.e. one narrow straight-out plume, then a wider plume to follow. Happens when the impactor goes into the surface ( a soft layer ) then goes kerpow. Doug |
