I give the Space Studies Institute $300/year (to increase once I have a real income), along with a few thousand other people contributing similar amounts. This is a far greater level of support than the typical "space activist". If a significant fraction of these "millions of people" did the same, a private space program would be a reality. Since we don't see this level of support, I think it's fair to say that the public's interest in space does not extend to their bank accounts. I don't buy the argument that the mere existence of NASA somehow prevents people from funding non-govt. space activities. That's part of the whole NASA-bashing ideology that's developed over the last 3 years, which provides lots of inflammatory comments but little constructive action. There are many ways to help bring about the sort of space activities we dream of, but many people would rather talk about how the evil NASA big-aerospace loving statist bureaucrats are solely responsible for the lack of a vigorous space program, instead of making a personal commitment of time and money. -- Jon Leech (leech@cs.unc.edu) __@/ ``Before I refuse to take your questions, I have an opening statement.'' - Ronald Reagan ------------------------------ Date: 4 May 89 17:40:45 GMT From: blake!mm@beaver.cs.washington.edu (Eric Gorr) Subject: SETI: What has it done I have heard a lot about SETI and was wondering if all you experts could tell me what exactly the research has provided.

Oops - Magellan's solar panels *will* be deployed before the IUS burn, so it is just the IUS's batteries that can run down. I am not sure if the IUS's inertial navigation system can keep the necessary accuracy if left in orbit for a few weeks or so, either. -- ------------------------------------------------------------------------------ "Captain, I see no reason to stand here | Stuart Warmink, Whippany, NJ, USA and be insulted" - Spock | sw@cbnewsl.ATT.COM (att!cbnewsl!sw) -------------------------> My opinions are just that <------------------------ ------------------------------ Date: Thu, 4 May 89 13:54:54 CDT From: pyron@lvvax1.csc.ti.com (c, it's not just a good idea, it's the law) Subject: RE: Near miss Dale.Amon@H.GP.CS.CMU.EDU writes: >When you start thinking about Tunguska, the early 70's pass above, the >.5M mile misses of really big stuff in the last 25 years ... it makes >you feel like you're sitting on the bulls eye of some cosmic dart >game.

The reason for not testing outside, to say nothing of space, is that to do so violates some provision of the ABM Treaty, which our glorious leaders have already decided may or may not apply in some or all of the circumstances here, sort of. Anyways, my understanding of this weapon is that it will be about 20cm in diameter, and may have some sort of contact explosive to enhance the impact damage, but not a warhead.

Hercules Aerospace is not a small company. They are spending hundreds of millions of dollars of their own money on getting into the private space launch business. As the DOD/NASA trough dries up expect to see more and more major aerospace companies going into private space in a big way. All these companies are in business to make money. When they can't make it off of the government they will figure out how to make it off the private sector. Graham-Ruddman(sp?) may be the key to private space operations. Bob P. P.S. What are you doing to celebrate space week? It looks like we have enough displays lined up to fill a shopping mall, a planetarium, and a convention center. With any luck we will have both astronauts and cosmonauts as guest speakers. It looks like we will have displays from both NASA and the Soviet Union also.

What about the National Geographic > Society? Or a university consortium? ^^^^^^^^^^^^^^^^^^^^^ You are forgetting something here. Where would universities get the money to fund a research project like this?? Probably the same place they get most of their research funds. The biggest source of research funding in the U.S. are ( ask any grad student :-) ) (1) Dod (2) National Science Foundation (NSF) and other gov agencies So saying that universities could replace government funded space probes is a bit circular.
