A custom-designed tug will still be superior, as it *will* carry less extra weight. Whether that will make it worth developing one will depend on how many customers there are for it. We've already seen an example of this, with TRW's OMV cancelled because there were only two missions for it and the shuttle alone could do those adequately (maybe not optimally, but adequately). If it doesn't need to be done very often, refuelling an SSTO will be a cheaper approach. >Will they go to lunar orbit?

Our atmosphere greatly complicates the flip maneuver; it's the main reason why the flip is hard. In vacuum it's trivial. In principle, a DC-like SSTO could land on the Moon. -- SVR4 resembles a high-speed collision | Henry Spencer @ U of Toronto Zoology between SVR3 and SunOS. - Dick Dunn | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: Thu, 13 May 1993 18:07:41 GMT From: "Allen W. Sherzer" Subject: Details of DC-X followon vehicle firming up. Newsgroups: sci.space,talk.politics.space The basic approach for the DC-X followon seems to be firming up at SDIO. The original plan was to make the DC-X1 a small very incremental test vehicle. It would have taken 42 months to build and cost $600M. Funding this would take $100M next year. Others wanted more aggressive designs but Worden at SDIO wasn't going for it. However, they now have settled on a version which is not only better, but faster and cheaper as well. This will take 33 months and cost $420M. It will be as close as possible to the DC-Y except smaller. It will hold istelf to the same mass fraction, use the same materials as DC-Y, and in every way simply be a smaller version of DC-Y. All that will be needed then to build the DC-Y or DC-1 will be scaling up. Unfortunately, this includes the engines since this vehicle will use the RL-10 and not the RL-200. However, since both turbopumps for the RL-200 exist and are space qualified today, this isn't as hard as it sounds. In addition, the time and cost have been approved by OMB. Equally important, this vehicle can be built within the Clinton Administration which will help it gain administration support. Your support is still needed. Grassroots activism on this has been and will continue to be a key part of the strategy to make this happen.

Sherzer" Subject: Draft of SSTO report language Newsgroups: sci.space,talk.politics.space Below is the draft language of the report language to support SSRT. I just got permission to publish it so here it is. I also have a couple of new tidbits which I will post shortly. Allen Draft Report Language -- For Inclusion in the FY '94 DoD Authorization Bill Single Stage Rocket Technology (SSRT) Program Of all the dual-use spacelift technologies currently targeted for operation within a decade, reusable, Single Stage to Orbit (SSTO) rockets offer the highest potential for radically reduced costs and increased safety, reliability, and operability. According to recent studies performed for the Air Force and NASA, SSTO's have the potential of reducing the operational cost of delivering payloads to low Earth orbit by an order of magnitude, restoring U.S. competitiveness. The Strategic Defense Initiative Organization (SDIO) is carrying out a well-planned Advanced Technology Demonstration (ATD) program to demonstrate the availability and cost effectiveness of Single Stage Rocket Technology (SSRT). The SSRT program is structured to rapidly prototype and fly experimental vehicles of increasing size and performance to demonstrate the feasibility of single stage reusable rockets one step at a time, within budget, and in a short time. The SSRT program is important because it will provide the DoD with a demonstrated SSTO technology option for consideration as a next generation spacelift system. The first ATD vehicle, the DC-X1, is on schedule and within budget, and positive conclusive results are expected by the end of fiscal year 1993. The second ATD vehicle, the DC-X2,is scheduled to begin development in fiscal year 1994. Successful flight testing of the DC-X1 and DC-X2 will provide the confidence necessary to proceed into initial development of a full-scale operational SSTO system. The Committee is concerned that the SSRT program is only budgeted at $5,000,000 in fiscal year 1994, and questions the level of funding support available within SDIO for completion of the DC-X2 ATD. Based on the expected positive results from the DC-X1 flight tests, and because of the significant potential that single stage rockets promise for reduced costs and increased reliability and operability, the SDIO is directed to begin development of the DC-X2 in fiscal year 1994. The Committee also directs SDIO to evaluate the feasibility of transitioning the SSRT program in fiscal year 1995 to appropriate new management commensurate with its dual-use nature, such as the Advanced Research Projects Agency (ARPA) or the Technical Executive Officer (TEO) structure within the Air Force, and to provide its recommendations to the Committee by August,1993. The Committee directs that $100,000,000 be authorized in fiscal year 1994 for SDIO to proceed aggressively with the SSRT program, including development and flight testing of the DC-X2 ATD. -- +---------------------------------------------------------------------------+ | Lady Astor: "Sir, if you were my husband I would poison your coffee!" | | W.

The engineering >needs of a space tug and a lunar transit vehicle are very different >from those of an SSTO rocket... Indeed they are, but the question is, are they *too* different for one design to meet both? The one thing that seems to me like a potential problem is adequate view for the landing (which is what ultimately killed the Earth Orbit Rendezvous mission mode in Apollo -- being able to custom-build the lander for a good view looked better and better the more it was studied). >... you *might* be able to gas up an empty DC-1 in orbit and >fly it to the Moon. It sure ain't the way to build a cost-effective, >lightweight Moon bus or GEO-tug! True, but that doesn't mean it shouldn't be done that way. There is a general pattern in technology: general-purpose solutions eventually drive out special-purpose ones (or drive them into specialized niches). If the general-purpose solution is good enough, nobody wants to bother developing a special-purpose one, even if it would be somewhat better. Once there were specialized keyboard-encoder chips to scan keyboard keys and encode them into a binary code. Now everybody just uses suitably-programmed one-chip microcomputers -- an entire general-purpose CPU doing nothing but scanning keys in your keyboard! The micros are easier to develop, easier to customize, and relatively cheap. It's not worthwhile to develop optimized solutions any more. Is DC-1 good enough to reach the point of driving out specialized craft? That's less clear. But the idea is not ridiculous. -- SVR4 resembles a high-speed collision | Henry Spencer @ U of Toronto Zoology between SVR3 and SunOS. - Dick Dunn | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: Thu, 13 May 1993 18:29:11 GMT From: "Allen W.

It will now be BMDO (Balistic Missle Defense Organization). Looks like Clinton is going to keep his promise to get rid of SDIO by changing the name. 2. The HASC R&T Subcommittee markup has been delayed for one month. This means you all have more time to write and call to support the language for SSRT. It also means that the Appropriations Committee will finish before HASC so we need to start a strategy there (more on that later). 3. It looks like some NLS types may be hurting chances for SSTO within Spacelifter. They have skewed the analysis being done against SSTO's to make expendables look better (more on this later).

I'm saying what the history of life and our species suggests is most likely. The fact that well-informed people make extra effort to keep from infecting other planets with life, via our probes, suggests that what I said above is very likely, maybe inevitable. The whole point of space exploration and exploitation is to do exactly what you think I am saying we should do. We belong to the Earth as much as it belongs to us, so our efforts to get into space may well be (I think, in some sense, it is) the Earth's efforts to spread life throughout the solar system. Maybe my not expounding on this idea is why you think I am trying to allocate "our planet's" resources. Also, the whole thread had a tone of definitive answers to the meaning of life, so relax, we're just talking. The fact that you (from what I can tell) disagree must mean that I'm not the definitive source. I say that 'we're it' because only our species has shown the capacity (so far) to leave the Earth, a necessity for spreading life beyond Earth. ...later... >>Sorry. The sum purpose of life on Earth is to evolve to the point where >>life can leave Earth and live elsewhere as well. And we're it. James D. Nicholl sez; > Evolution isn't a directed process and doesn't proceed towards >a specific goal. It's not directed, but it's products are predictable: greater diversity of life-forms and environments, and the general spreading of life, among others. Both of these effects would be the result of our movement into space on a large scale. Besides, we already are evolved to the point where we can leave the Earth. If life gets a foothold in space, "Life on Earth" will mean as much to "Life in the solar system" as "Life in my backyard" means to "Life on Earth" right now. If you asked my dandelions what their purpose is, they would very likely tell you "To get into all your neighbor's lawns", judging from the way they act. The purpose of life is to spread and live. Our efforts in space will do exactly that, or probably be judged a waste of time and effort. -Tommy Mac ------------------------------------------------------------------------- Tom McWilliams 517-355-2178 wk \ They communicated with the communists, 18084tm@ibm.cl.msu.edu 336-9591 hm \ and pacified the pacifists. -TimBuk3 ------------------------------------------------------------------------- ------------------------------ Date: Thu, 13 May 1993 18:42:33 GMT From: kjenks@gothamcity.jsc.nasa.gov Subject: Life on Mars.

One part modifies the launcher so that humans can survive/function goint up on it. The second part deals with extra instpection and features added to insure that the launcher is 'extra safe' for the human. I assert that launchers which go through this extra inspection don't seem to be any safer than the ones which don't. It is this second part I object to as wasteful.

NASA as a government organization didn't develop much "new technology", the various contractors that supplied the boosters and spacecraft to the agency did. Tell IBM, Boeing, Hamilton Standard, Aeronca, Grumman, North American Aviation, Rocketdyne and a thousand other American companies that new technology wasn't invented as a result of the space program. The phrase "Necessity is the mother of invention" was never more true than it was to these companies in the 60's. >THe saturn V was remarkable, not for technical innovation, >but for size. It was truly enormous, and thus required >solutions to problems not seen at that scale. I diagree. Ithink the Saturn V _was_ remarkable for its technical inovation _because_ of the problems that had to be overcome at that enormous scale. I don't think that you can say in the same sentence that it wasn't innovative and that it also required new solutions to new problems caused by scale. That seems contradictory to me. Developing techniques for constructing hemispherical tank domes that could be common bulkheads between two chemicals stored at temperatures which differed by a hundred degrees required new insulation technology. Making a dome thirty feet across so thin that it couldn't stand on its own without being pressurized required innovative pyrotechnic metal forming techniques, not to mention micro-precision welding processes. The list goes on and on and I never even mentioned engine design. Usually, new construction methods which were theoretically possible needed to be performed. In order to make them happen, the machines and the materials needed to be manufactured from scratch. The question is where you draw the line between theory and real application. In my definition of invention and innovation, just because you got the theory from some university professor, dosen't mean that there isn't a lot of innovation necessary between his paper and the actual hardware. >many things are well known in lab environments, but it can often >take a "MAJOR" project like the MANHATTAN project, the Apollo project >or the Forbin project to really push the ideas off the bench. True, I agree. However, going from the blackboard to the launch pad is always puctuated with problems never dreamed of in the theory stage that need to be worked out. That's innovation. -- -------------- Gary Schroeder schroede@bnlux1.bnl.gov Brookhaven National Laboratory ------------------------------ Date: Thu, 13 May 1993 16:14:55 GMT From: Conor Frederick Prischmann Subject: U.S. Government and Science and Technolgy Investment Newsgroups: sci.space,talk.politics.space,sci.research,talk.politics.misc,talk.politics.libertarian,misc.education In article <1srfii$79k@suntan.eng.usf.edu> mccolm@darwin.math.usf.edu.

I do not for a second doubt that toilets will be needed. The point is that (you may not know this) the GAO looked at the Shuttle toilet procurement and found that well over half the money was wasted. This ignores the fact that Skylab had a toilet which seems to have worked OK. I note a common element to all your posts: you never seem to worry about costs.
