Nothing that I hadn't heard before (use E.T.s for telescopes by filling them with CO2 and looking for gamma rays, use them for garbage cans for the Space Station, etc), but on this program they interviewed some NASA official and asked him why they never put the E.T.s into orbit after taking them 99% of the way there, when the cost to put that amount of mass in orbit would be $300 million if done any other way. He mumbled that it had never been proven to be cost effective. I wonder what paragon of economic efficiency he was comparing it with. The shuttle?

That's why I believe NASA should, if it is not completely disbanded, be limited by mandate to doing onthing but preliminary technology development. They should be completely out of the planetary science and research business. I would like to see them with a mandate to test laser launchers, rail guns, ram accelerators, sky hooks, tethers, ion engines, solar sails, CELSS. The list could go on for pages. The technology they develop should be available for the overly conservative don't-try-anything-new-on-my-experiment planetary people to use if they wish, and for private companies to develop as they wish, just as NACA did in the 1930's. If instead of doing technology research, NACA had been the central agency controlling all aircraft development and use, we would still be discussing the incredible technological feat of delivering 100 tons of payload across the Atlantic using a $1000000000 fleet of scaled up Wright Flyers and a series of tethered floating landing fields in the Atlantic... ------------------------------ Date: Wed, 1 Mar 1989 18:38-EST From: Dale.Amon@H.GP.CS.CMU.EDU Subject: Pittsburgh L5 operating CBB for NSS CBB with daily upates of material from NASA, NASA Select and other sources is available at 412-366-5208 Please call in and check out what happens when a professional writer runs a CBB. ------------------------------ Date: 1 Mar 89 20:14:47 GMT From: dvnspc1!tom@burdvax.prc.unisys.com (Tom Albrecht) Subject: Re: LANDSAT TO BE SHUT OFF SOON--PLEASE WRITE YOUR CONGRESSMAN Could you post details about committees, committee members, etc. so that we can write?

In case anyone is wondering why this decision is being made now, as opposed to years ago (given that the HST launch is far behind its original schedule), the modified C-5A wasn't available until very recently. The modifications are for carrying big USAF space hardware, presumably spy satellites, but the HST will fit. > "We opted for the C-5 because it will require significantly >less shipment time and provide us more flexibility in our >shipment schedule,"... It will also greatly improve security, not an entirely trivial issue. The HST would be a terrorist's dream of a hostage. Nobody was terribly happy about sending an astronomically :-) expensive, irreplaceable payload all that way (via the Panama Canal) by ship. -- The Earth is our mother; | Henry Spencer at U of Toronto Zoology our nine months are up. | uunet!attcan!utzoo!henry henry@zoo.toronto.edu ------------------------------ Date: 28 Feb 89 17:47:00 GMT From: m.cs.uiuc.edu!s.cs.uiuc.edu!noe@uxc.cso.uiuc.edu Subject: Re: SPACE Digest V9 #257 >> what about: there's a guy i know who uses his cat to clean his instrument. >> he removes the optical component package at the viewing end and slides the >> animal through the tube to pick up the dust. > > If you look through the tube at the same time, would you get a CAT > scan? :-) No, you'd get your nose clawed up.

Listen dip! if you want to include something I say in your message, then by god, include it all! don't go paraphrasing and cutting out parts of my sentences and paragraphs to further your viewpoint. what I said was: ------ This is an arguement that will never be resolved. There are those like me who support a Manned Program, and nothing you say will change our minds. And those like yourself and Mr. Dietz, who oppose a Manned Program in the present, and nothing I or anyone else will say will change your minds. Not that I am saying that any of us (your group or mine) is closed minded. I just feel that this is a subject that neither of us will budge on. --- Now in the context of the other sentences, I hope that my meaning is clearer. This arguement has been going on between you, Dietz and Mr. Spencer for over a month. Have your convinced Spencer of your viewpoint? Have I or Spencer convinced you of our viewpoints?

You will always find some rationale to refute anybody elses viewpoint and support your own. You have so far! To me this is like argueing politics or religion.

Have your convinced Spencer of your viewpoint? Actually, our positions are not all *that* far apart. Mostly, the difference is in how fast we expect launch costs to drop. I expect they will come down slowly. Henry (and many others, I hazard) are counting on private firms to do orders of magnitude better than NASA, and to do it soon. My mind would be changed if someone could demonstrate that launch costs would be (picking numbers out the air) $200/lb to LEO in fifteen years, from the current $4K/lb or so (would anything change *your* mind?). Past history is not reassuring. I don't see costs coming down if NASA continues to spend so little money on developing new launcher technologies. Ah well, maybe ALS or NASP will save us (:->).
