Nasa TV will be starting coverage in about 3 mins - but I'm watching multiple TV channels to see if any carry coverage - and will post any news thru the day as it happens

(1) The DISR team has put the raw images, back onto their site, claiming that they took them down while "analyzing the data": http://www.lpl.arizona.edu/%7Ekholso/data.htm . It's possible that they may have cranked up the contrast from the originals; I haven't done a detailed comparison yet to the originals on "Lyford's" site. (Also, I still don't see the 2 to 4 isolated HRI frames that they were supposed to get between 500 and 200 meters altitude; I suppose they might have lost those on Channel A. I'm awfully hard to satisfy.)
(2) The DISR camera head was supposed to be 45 cm (18 in.) off the ground after landing, assuming that the probe landed upright and didn't sink in. Since it MAY have sunken in a little, the images may be even closer to the ground. (3) It was stated at the last press conference that the excellent Huygens tracking from those 18 ground radio telescopes (and they showed two graphs to show just how clear the Doppler and VLBI data was) should be able to recover the data lost from Cassini's own Doppler wind measurements "in full", although it may take a while to complete the analysis. (4) Even if Guillaume did miscalculate Huygens' exact landing spot, his work seems to me absolutely superb, and indispensable right now for anyone interested in Titan. |
