NASA and the Vision thing
On Mon, 12 Dec 2005 12:11:07 -0500, in a place far, far away, "Ami
Silberman" made the phosphor on my monitor glow in such a way as to indicate that: No, infants can be mass produced. Astronaut trainees require, at the very minimum, twelve years of high school, four years of college, and several years of post-college education. That doesn't have to be the case. NASA just has historically chosen to establish those as the criteria. On-orbit satellite repair could actually be a blue-collar job. It doesn't require a PhD. But it would be a Blue-collar job which requires a hundred or more hours of training per each hour of actual on-orbit work. How much money (in training), does it take to become a master plumber or electrician? Or an airline pilot? It's still not that big a deal, compared to training an astronaut, at least the way that NASA does it now. |

Sure, they will probably need cleaners, but those cleaners will need to be
able to conduct EVAs, including emergency procedures. No different, really, from the divers who clean underwater windows. (Except that usually those divers are pretty near the surface.) Could I remind everyone that it was a British Scorpio (UNMANNED) that rescued the Russian submariners. Not divers on oxygen/helium. |

I suspect that most extra-terrestrial window cleaning will be robotic until such a time as EVA becomes "routine". Once EVA is routine, and frequent, then it may be easier, simpler, and cheaper to have a human clean the windows, perhaps along with other minor maintainance. (My understanding is that, at some aquariums, the windows are cleaned by volunteers from local diving clubs who like the idea of being able to swim with sharks etc. without having to leave, say, Dallas. |

"Scott Hedrick" wrote in message news wrote in message oups.com... The Shuttle is no more reusable than Ariane 5. That is a lie. The lower stage or Ariane is in fact recoverable. There are significant parts of the Shuttle which are nor recoverable. Exactly how many Ariane lower stages have in fact been recovered and reflown? Verifiable cites, please. Still waiting for your answer, "ianparker2", or should I say, Stuffie? |

"Scott Hedrick" wrote in message .. . wrote in message oups.com... My postings seem to have raised a stir. More like a good laugh. Nothing we haven't seen before. Now try answering the question I asked: Please provide verifiable evidence that Cassini was *designed for* and *is performing* work requiring anthropomorphic manipulators. It's been more than a week. Still waiting for your answer, "ianparker2", or should I say, Stuffie? |

Please provide verifiable evidence that Cassini was *designed for* and *is
performing* work requiring anthropomorphic manipulators. It's been more than a week. Still waiting for your answer, "ianparker2", or should I say, Stuffie? It was not specifically designed. However that is not the point I was making which was that automatic equipment can work well in a hostile environment. I mentioned that Cassini had moving pats. In a vacuum there is a question mark over bearings, moving surfaces and lubrication. Cassini answers questions. Exactly how many Ariane lower stages have in fact been recovered and reflown? Verifiable cites, please. Still waiting for your answer, "ianparker2", or should I say, Stuffie? The same number as the number of missions. The bottom line is of course $/Kg, the value for the Shuttle being twice that of Ariane. Proton and Long March are of course even cheaper but P/LM are only cheaper because of labor costs. Ariane is based comperable rates per hr and therefore we can make claims for it being a "better" system.. |

Still waiting for your answer, "ianparker2", or should I say, Stuffie? It was not specifically designed. Then mentioning it was a red herring, intended to deceive. However that is not the point I was making which was that automatic equipment can work well in a hostile environment. Then you should have said that. *You* brought up anthropomorphic manipulators. Like Stuffie, you are trying to retroactively change the subject, rather than admit you were wrong. Exactly how many Ariane lower stages have in fact been recovered and reflown? Verifiable cites, please. Still waiting for your answer, "ianparker2", or should I say, Stuffie? The same number as the number of missions. So, then, are you saying that the *exact same* lower stage of Ariane has been used in every flight? Let's see a verifiable reference to the number of Ariane lower stages that have flown more than once. Otherwise, *once again*, Stuffie, you're trying to retroactively change your posts. The subject of the thread was reusability- if Ariane has not reused stages, then mentioning it was clearly deceptive. Proton and Long March are of course even cheaper Have they reused stages as well? |
