Here it is: ====================================================================== Ron Paul's Space Policy Libertarian Party Presidential Candidate Time after time NASA has developed capabilities at great expense then discarded them: a space station larger than the Soviet MIR, a heavy lift vehicle competitive with the new Soviet Energia, a nuclear engine twice as efficient as the space shuttle main engine, and a well-tested Earth-Moon transport system. The fate of the Saturn V heavy lift launch vehicle is one of the saddest examples of this folly. Production was intentionally halted and portions of its tooling were "lost." This bridge burning ensured support for the next aerospace welfare program: the space shuttle. Now we have a grounded government shuttle that can lift only a third as much as the Saturn V for the same cost per pound. That's progress, government style. Even worse, this failed state monopoly is now wrecking businesses to avoid well-deserved embarrassment. American companies desparately need to get their satellites into space. But they have been blocked from using the cheapest, most reliable launcher in the world which unfortunately happens to be the Soviet Proton. NASA has cost our nation a full twenty years in space development, twenty years that has seen the Soviet union surpass us to such an extent that may well be irreparable. It is inconceivable that a private firm could have committed such follies and survived. NASA deserves no better. Our only hope now lies in the power of free individuals risking their own resources for their own dreams. We must recognize the government- led space program is dead and the corpse must be buried as soon as possible. Any defense functions should be put under the military, and the rest of NASA should be sold to private operators. The receipts would be applied to the national debt. Then, all government roadblocks to commercial development of space must be removed. It is not the business of the Defense Department of a free society to veto business decisions of remote sensing or launch companies. The interests of liberty would be well served by a bevy of mediasats that put any future Iran-Contra affair under the full glare of live television coverage. Maybe, besides the competition, that's what our government is afraid of. There's really only one proper role for the military in space or on Earth: the protection of America. Otherwise, the new frontier of Space should opened to all. Space pioneers will generate knowlege and wealth that will improve the lot of all people on earth. We should not let government get in their way. SPACE -- INTERNATIONAL POLICY Our government is not only short-sighted in its negotiations on space issues, it's downright antiAmerican. Sometimes it's hard to decide whose principles the State Department is defending. They certainly aren't those of the Founding Fathers. About the only anti-property treaty this country hasn't ratified is the odious "Moon Treaty" written by our own Satate Department. If not for an alert group of citizens (L5 Society), the United States would have ratified this treaty under President Carter and embraced control of all of the rest of creation by a World Government. Under "the common heritage of mankind" space would be the heritage of no one. The vast wealth of resources and energy in our solar system would remain untapped instead of being explored by entrepreneurs who would improve the condition of all humanity. It's time this sick treaty is repudiated once and for all. We must also demand a revision or understanding to the 1967 Outer Space Treaty so individual property rights are recognized. If there are no implementing protocols for property rights within a specified time limit we should withdraw from the treaty entirely. In any case, we should immediately open a land office and accept claims of Americans to specific pieces of land, subject to occupancy within fifteen years. Back in the late 1950's a project called Orion seriously considered using small nuclear explosions to power a spacecraft. The lifting capacity would have been vast, measured in thousands of tons instead of the miniscule abilities of today's mightiest rockets. This brute- force approach was simple enough to be considered feasible 30 years ago. Unfortunately, the idea was shelved by the 1963 Nuclear Test Ban Treaty. If we truly wish to see the opening of the space frontier, we must not prevent businesses from working on futuristic ideas like fusion drives or matter-antimatter engines. Such technologies will one day open the solar system to commerce the way the clipper ship opened the oceans in the 19th century. A time may also come when industrial nuclear explosives are needed in deep space for extraction of the vast wealth of resources inside comets and asteroids. Modification of the 1963 Test Ban Treaty and other understandings to clearly allow such non-military use of nuclear technology is in the best interest of all space-faring peoples. But perhaps most basic of all, we should question why governments of the 20th century Earth assume they have the right to make laws for unknown environments, at distances of millions of miles and a time decades or centuries in the future. If the arm of government can reach that far, freedom on Earth is precarious at best. ====================================================================== End of policy statement by Ron Paul. ====================================================================== I've heard only one justification from Dale for his vocal and impassioned arguments for full NASA funding under its business-as-usual approach of "wrecking businesses to avoid well-deserved embarrassment" in the words of Dale's own candidate. This explanation is that he is speaking as an official of the National Space Society and is, thus, under an obligation to argue and promote the official views of the Society as determined by the Legislative Committee. Others, such as Henry Spencer, have offered their uninvited justification for Dale's actions in terms of political pragmatism of some kind, although Dale has yet to offer these justifications himself. Given the fact that Dale is under no obligation to speak on behalf of the National Space Society, that the policy which he claims to have contributed to is clearly an impassioned plea to put an end to NASA's anticompetitive and wasteful practices, that Dale signs his own name to his impassioned pleas for full NASA funding and that he has yet to offer any believable political strategy in which identifying full NASA funding with the most viable political strategy for opening the space frontier is more than a thinly veiled attempt to mask his own hypocrisy, I call on Dale to now present such a justification or offer the honest truth about why he is talking out of both sides of his mouth.

No they haven't. They built and flew what amounted to a big sounding rocket. The various Conestoga satellite-launchers are still paper designs. And do remember that that one launch was something like five years ago. > And they > are offering their launchers to DARPA on a strictly commercial basis. Precisely what OSC+Hercules are doing with Pegasus, I believe. > If DARPA commits to buying launches on a vehicle which is still in the > development stage, how is that significantly different from them paying > for development? Having the government as a customer is very different from having it as a partner. Unless I am much mistaken, DARPA will pay only for launches, not for promises. That's a BIG difference. > What happens when there are cost overruns and production delays? Presumably, existing contracts would have to be renegotiated (unless there were provisions for such already present), leading to possible loss of business. Same as what happens when Boeing hits delays or overruns on a new airliner. > The article also raises questions about possible > hidden subsidies: How much are OSC and Hercules paying for use of the > NASA B52? How much are they paying for computing at Ames? This I don't know. I would speculate that the B-52 is being provided on a basis of "until we have our own carrier aircraft, the customer has to supply it". Ames is presumably involved in this for its own reasons, and may consider free computing time justified. Remember that NASA *is* charged with advancing aerospace technology for use by private industry. > Hercules and OSC claim that they will develop, build and certify not > one, not two, but three new motors with $45M, and in one year... I confess that the motor development sounded a bit ambitious to me too. However, the standard rule of thumb is that doing things privately and accepting some risk is an order of magnitude cheaper than having the job done by the government. $450M for government development of three small solid motors, by an experienced company, doesn't sound too bad. Likewise a time of two years (not one -- this project is already well underway, remember) doesn't sound too bad for motors that don't involve new technology. They should represent a fairly routine engineering job. That, actually, deserves some expansion. Although I wish OSC+Hercules success, and gobs of money, their most important contribution will be their first successful launch. If they go broke despite technical success, that will still establish the crucial point: getting into orbit is routine engineering now, and does not require a billion dollars, ten years, thousands of people, or government funding. If they can pull it off technically, and I suspect they can, that will be an enormous contribution to convincing investors that private spaceflight is realistic. There are two problems with investors: convincing them that you can do it, and convincing them that you can make a profit on it. The first problem is the hard one, especially since NASA is all too eager to assure the investors that billions of dollars and thousands of engineers are absolutely necessary. Proving that assertion a lie is very important; so far it hasn't been done. The problem with Space Services is that they've taken so long to deliver; the problems with Amroc and Pacific are that they insist on developing new technology, and that they too are showing signs of having trouble delivering soon (I for one consider it a bad sign when the design of the vehicle changes repeatedly, over a period of years, before anything actually flies). If Pegasus works, it will demonstrate that a short development program using existing technology is sufficient. That would make a vast difference to getting funding for private-spaceflight projects. > One of the more important aspects of this article is the tense... > Hercules and OSC have far to go before this project amounts to much more > than the inflated claims of a marketing campaign... One of the more important aspects of this article is the timing: after the project is well underway, not before it gets started. I doubt very much that an official announcement could possibly have been postponed any longer, actually. Given the way the aerospace industry usually ballyhoos its back-of-the-envelope design sketches, OSC and Hercules have actually shown remarkable restraint. -- Anyone who buys Wisconsin cheese is | Henry Spencer @ U of Toronto Zoology a traitor to mankind. --Pournelle | {ihnp4,decvax,uunet!mnetor}!utzoo!henry ------------------------------ Date: 10 Jul 88 01:12:31 GMT From: mnetor!utzoo!henry@uunet.uu.net (Henry Spencer) Subject: Re: Rocket engine > ...

Well, one can sometimes get hints from knowing how similar problems were solved in the past, but I believe that's basically correct. Even the definition of "works" is rather ad-hoc; testing includes things like exploding small bombs inside the engine to try to stimulate any instabilities that might be lurking. -- Anyone who buys Wisconsin cheese is | Henry Spencer @ U of Toronto Zoology a traitor to mankind. --Pournelle | {ihnp4,decvax,uunet!mnetor}!utzoo!henry ------------------------------ Date: 10 Jul 88 00:36:11 GMT From: mnetor!utzoo!henry@uunet.uu.net (Henry Spencer) Subject: Von Braun quote > > Man is the best computer we can put aboard a spacecraft. --Von Braun > > Last week's successful Ariane-4 launch put AMSAT Phase 3-C and two other > satellites into [a very precise] orbit... I'd like to see some fighter > jock/astronaut do as well by flying a launch manually... "The Lord has delivered him into my hands." -Huxley Yup, the computer did a fine and very precise job. Now, Phil, cast your mind back a little ways, to the Ariane launch of AO-10 (I think it was). Much the same computer, running much the same software, controlling much the same booster, put AO-10 into a nice precise orbit. After which the same computer, mindlessly following orders, proceeded with a venting procedure that caused the third stage to catch up with and collide with AO-10, damaging it seriously and causing a lot of headaches for you and the rest of the Amsat crew. The greenest student pilot could have prevented that, if he'd been there. You, of all people, should not be lauding the unmanned nature of Ariane as an unmixed blessing. I think we all agree that machines are generally superior for boring jobs that have to be done exactly right, especially when there are tight response-time requirements. Even Von Braun, after all, built computer- controlled launchers. And I think we would all agree that humans are generally superior for adapting orders to situations and coping with the unforeseen. Both the Solar Max repair and the Palapa/Westar retrieval succeeded (despite one or two false steps along the way) even though the original carefully-built equipment simply didn't work. The debate centers on the extent to which unexpected situations and unforeseen problems can be removed by advance planning. NASA, Arianespace, etc. have been insisting for a long time that nothing is left to chance and everything is foreseen. They have consistently been proven wrong. Sometimes the equipment can be convinced to cope, and this is trumpeted as further proof that humans are unnecessary in space. Sometimes the equipment just isn't up to handling a new situation, and this is written off as Just One Of Those Failures One Has To Expect -- even if it wouldn't have been a failure with a human on hand. Do I detect a small inconsistency here? Automatic equipment is the appropriate response to a well-understood, simple, repetitive job like relaying communications, taking pictures, or guiding a launcher. Humans are the appropriate response to complex, variable, unforeseen, one-of-a-kind situations like equipment failures, unexpected changes in environment, and exploration of planetary surfaces. To pick a close-to-home example, the success of satellite repair/retrieval procedures has been inversely proportional to the reliance placed on automatic equipment rather than humans -- compare the equipment-intensive Solar Max repair, a near-disaster, with the human-intensive Leasat repair, which worked so well that it was boring. > Perhaps you should limit the scope of this statement somewhat. If we're being pedantic, note that Von Braun did: he said "spacecraft", not "launcher", so Ariane isn't relevant. -- Anyone who buys Wisconsin cheese is | Henry Spencer @ U of Toronto Zoology a traitor to mankind. --Pournelle | {ihnp4,decvax,uunet!mnetor}!utzoo!henry ------------------------------ Date: 10 Jul 88 12:24:25 GMT From: jfc@athena.mit.edu (John F Carr) Subject: Re: advance space news from June 6 AW&ST -- Pegasus!
