Real on-site repair could be a time and money saver if done well. I'm not sure that there's much advantage to on-site fabrication until/unless one gets *very* fancy (ie. importing materials from some place like the moon, with the correspondingly lower transport costs). - Andrew |

In hindsight (always 20/20, right?), I'd say that the shuttle and the ISS were both boondoggles. The shuttle was built in order to transport stuff to a space station that didn't exist until 20 years after the shuttle's launch. You're neglecting the cold war mentality that existed at the time of the Shuttle's introduction. Grabbing the high ground certainly appeared to be (and likely was, even if it turned out to have been unnecessary) a reasonable strategy. - Andrew |

The materials and imaging work could all be done with unmanned spacecraft. The value of additional physiological work is questionable. We pretty much know the effects of zero G on the human body, and it's not pretty. We were designed for one G. Even if turned out that there were medical conditions that were treatable by low-G environments the benefit to society is far from clear given how expensive it currently is to send humans into space. But even if one grants that this work has value, it could be done with a much less expensive station provisioned by unmanned vehicles. rg |

I've read that there are also medicines that can be made in that environment much more easily than here. George Patterson Drink is the curse of the land. It makes you quarrel with your neighbor. It makes you shoot at your landlord. And it makes you miss him. |

I'm a very strong proponent of our space program, I was too, until NASA gave Moller five million dollars for more R&D on his flying car. |

In most, probably all, "repair in space" situations, you can build and launch a replacement satellite (and throw in some improvements on the side) for less than -- probably much less than -- the costs of launching and recovering the manned space vehicle that does the repairs. |

It is pretty easy to say the Shuttle or the ISS or Hubble or anything
else was a huge mistake; that the money would have been better spent elsewhere. Of course, then you would have people saying that where the money went instead was a huge mistake. If Mr. Park or Mr. Griffin think those were mistakes, it behooves them to say what would have been better. Heck, you could have spent all the money "fighting poverty" (or ignorance, or injustice, or whatever), and it probably would have been even less effective in accomplishing those goals. |

If Mr. Park or Mr. Griffin think those were mistakes, it behooves them to say what would have been better. Bob Parks has said what he thinks would have been better, several times over the years: http://bobpark.physics.umd.edu/index.html Search the archives for Space Shuttle and ISS. Here's the USA Today article on what NASA Administrator Michael Griffin said: http://www.usatoday.com/tech/science...nterview_x.htm This most certainly is not the complete text of the interview, but provides a little more context. |

There are no plans to send a shuttle to service the world's greatest telescope, but the schedule calls for 18 shuttle flights to finish the ISS, plus 10 ISS supply missions that's an average of 5.6 shuttle flights per year. Anyone who would bet on getting 28 flights out of these rickety-old jalopies has been living on some other planet. Even with a crew of just five, that's 140 rolls of the dice. That's a big gamble to support a space station that is now acknowledged to be of little value. But it's the world's greatest space station. If they were abandoning the ISS and were only sending up shuttles to fix the Hubble the same people would still be bitching about not saving the ISS. People just like to bitch. The "world's greatest telescope" is presently in development (the James Web Space Telescope). The Hubble is a great bird, but there may be limited value in keeping it going until the James Webb can be launched. --- Jay But it doesn't take pretty visual pictures. ------------------------------------------------------ DW |
