The only launch facilities that they share in common are the O&C which seems to be handling things alright and the Eastern Test Range facilities for range safety which don't exactly seem over burdened Also, I'm wondering about these claims (from you and others) that the shuttle is an inefficient way to get to orbit. Granted that I think it is normally silly to send people up to deploy a SynCom but look at the couple of times it was a good thing that we had people up there. And, if the shuttle is so expensive why are Saenger (how ever it is spelled) and Hermes being built (yes I know the difference between a taxi and truck) and why did Glavkosmos build Buran? >As to Freedom, that program is totally out of control.

Most astronomers are not extragalactic types, and thus do not fall into the category which most fervently supports HST. Most astronomers, if you take a moment to survey the field (you might check out, for example, the AAS's annual surveys) are photometrists and variable star people for whom HST is useless. In fact, it is worse than useless since it sucks away money from those things which are, in MOST astronomers's point of view, particularly interesting. Recall, for example, what happened when KPNO polled the users on whether, among theoretical options, all small telescopes on the mountain should be closed. The response was interesting -- most people wanted the 4-meter shut down instead, and the scientifically more productive (in terms of publications -- count 'em) smaller telescopes kept open. Of course, this viewpoint was ignored since it didn't agree with the Big Science viewpoint prevalent in D.C. >And another thing, HST has not failed!!!!!!!! I am tired of hearing >this.

Well, be fair: if Galileo *had* been flexible in its choice of launch vehicle, it would have been launched several years earlier, and would therefore have been dead or crippled before it reached Jupiter. (The nasty design defect in Galileo's thrusters was found during the post- Challenger grounding, when similar thrusters aboard TVSat 1 exploded.)

Yes, NASA is wonderful at doing the kinds of things it inherited from NACA. Aeronautical research is tremendously valuable to everyone concerned, and NASA's longstanding tradition of excellence in that area points the way to what it OUGHT to be doing in space, if space ever becomes as cheap to fly in as the air has been for the last 80 years. Someday when there are thousands of spacecraft plying the solar system, what sight would be sweeter than a small fleet of donated/retired craft decorated in NASA livery and performing research in materials and performance. Support from industry and government would be enthusiastic. Contrast this with the current reality, wherein NASA has tried for years to BE an industry as yet unborn, rather than waiting for it to form itself and then serving in a research capacity. We could debate the origins of this situation forever (and we may), but it should come as no surprise that the aeronautical and spaceflight divisions have distinct reputations, histories and performance records. > And if NASA >is so completely overfunded, then why are we still using *&$^%!

It would make a good testing range.... I'd like to know a bit more about where they'll be siting it, and how much room for expansion. I'm assuming that it's on the west side of the mountains along the coast, further north than Brisbane, to avoid the worst of the Pacific humidity; I'm also assuming that it's not right along the northern coast, in the typhoon belt and the aboriginal reserves. Dropping pieces onto the Barrier Reef may be a concern. As for people and infrastructure, that would have to be built. A nearby town or three would definitely spring up, and host a few research universities; I also assume that the Australian military would very much enjoy getting in on the act, or at least around it. Australian unions may cause a problem, as well as the penchant for 4 weeks of annual vacation at 17.5% above normal pay. Don't expect any major satellite production on Australia: delivery problems for the parts involved, especially electronics from overseas. Also, the work ethic is weaker. And there is always unease thinking about the sparse population of northern Australia and the explosive population of Indonesia not far off the northern coast....
