You are 100% right Ken. Somewhat understandable as it is, in a way, our major "first first" and everyone around wants a piece of the fame. Our "first first" was really Giotto. Memory is short, unfortunately, and ESA isn't good at pointing out its previous successes (let alone the present ones)... Steven |

Ken:
After watching the event on NASA TV, I'd have to say that I somewhat agree with the analysis. http://www.spacedaily.com/news/oped-05g.html The landing was a great achievement for ESA. They simply don't have the kind of experience with this sort of dog and pony show that the U.S. has. We're young and petulant, want everything Now! and, in general are as much concerned with style as with substance. I'm sure that ESA will hear these criticisms and improve their performance during future successes. Davoud -- usenet *at* davidillig dawt com |

which acounts for ABC News not saying a word or a pic last night
here in the US of A ? Steven Van Impe wrote: Ken wrote: After watching the event on NASA TV, I'd have to say that I somewhat agree with the analysis. http://www.spacedaily.com/news/oped-05g.html So, for you the headline is that ESA did a bad job with the broadcast (and oh yeah, they landed on Titan as well)? I agree completely that the PR on this mission could have been a lot better, but we _did_ land a probe on a moon of Saturn! ESA is largely governed by politicians, so it's only natural that we do our best to please them. In the US, Space missions are made or broken by the television audience, so NASA does their best to please the media. A live broadcast of the Huygens decent would get next to no attention on any European tv channel. There's no reason for ESA to prioritize live broadcasts. It's sad, and I wish it were different, but that's how it is. Regards, Steven |

You've been watching CSI-Walmart too long!

And in terms of computational complexity (accuracy notwithstanding!!!), timed event prediction and gravitational expertise, the ESA is ahead of everybody now, by, say, what, the ratio between the distance to Titan, and the distance to Mars? :-) *Cough* Kudos to the ESA and Huygens -- which among its six instruments is one developed at the University of Arizona, USA. Just so happens to be the instrument responsible for the imaging. :-P -- -John Steinberg email: lid Go Gang Green! Out of curiosity, who built the failed radio equipment? didn't one channel die too early? |

The radio didn't fail, but a design oversight nearly cost them the
Huygens mission. ESA engineers failed to take the proper doppler shifts into account when designing and spec-ing the transmitter in Huygens. With the original orbit, the Huygens probe would have transmitted data, but the frequency would be shifted too much for the receiver in Cassini to capture it. They ended up altering Cassini's orbit and the Titan encounter schedule to minimize Doppler shift during the data transmissions. Looks like it worked. Michael Barlow wrote: |

from
http://www.spaceflightnow.com/cassin...15science.html As it turned out, Cassini never listened to channel A because of a software commanding error. The receiver on the orbiter was never commanded to turn on, according to officials with the European Space Agency. "We should remember we're human and we should learn lessons, so I will institute an ESA inquiry on how the command came to be missing," David Southwood, director of science for the European Space Agency, told reporters today. "I'm not going to say any more about that, I'm not going to speculate (about blame)." In an obvious reference to NASA and earlier news reports, he did say "there have been some erroneous messages implicating one of the other space agencies involved. No. It's an ESA responsibility." According to published reports, an ESA official said earlier that the missing command was part of a software load developed by ESA for the Huygens mission and that it was executed by Cassini as delivered. "There isn't any doubt that the command was missing," Southwood said today. "But I'm not going to say any more because the point of an inquiry is to find out. We will certainly have NASA representation on the inquiry, but I don't want to make a big thing about it." "Tim Killian" wrote in message ...

ESA did (and are still doing) a terrible job getting this information
out to the web. Agree with all of the posts here wholeheartedly. |
