Dysprosium
Quote from: Spiceman on 07/11/2024 05:59 pmIridium, Teledesic, Globalstar were the three major efforts, but just like today with Kuiper and the chinese there were a bunch of other competitors, with the usual varied degree of seriousness (ARCA early seeds were probably planted back then... shudders).IRL Teledisc never happened and it was Orbcomm (launched on Pegasus solids that IIRC made the best running). BTW all went through Chapter 11 and still exist. The joke about Iridium (Element 77) shrank to 66 satellites, which is actually "Dysprosium" IOW it's possible to make a satellite comms business and (eventually) make a profit it at. But boy is it tough.

I did not cover STS until my last year at OMB — which was consumed by Columbia — so I never really dealt with that operational marching army. But my impression from that time is that a lot of underutilized workforce and facilities and overhead were bookkept against STS that had little or nothing to do with STS. I’m not saying dealing with those problems would have cut STS costs in half, but if Griffin had not killed full-cost accounting and if program managers had been given more authority and responsibility for their program costs and budgets, STS costs might have come down at the margin and NASA would have its arms around Orion/SLS costs much better than it does today.
The subcommittee should also note that tens of millions authorized and appropriated for military spaceplanes in the 90s was often diverted for other purposes. I understand the NASA historian has written a very interesting paper on this subject, and suggest you may want to review it.

I understand the NASA historian has written a very interesting paper on this subject, and suggest you may want to review it.I suspect the funds were legally diverted with notification to congressional appropriators. It’s true that Clinton Administration policy divided space launch development responsibilities between DOD for EELVs and NASA for RLVs. And it’s probably true that DOD funds appropriated for RLV (or MSP or whatever) development we’re redirected to other DOD programs/purposes after that Clinton policy came into force. But that doesn’t mean that there was any illegal or even suspect accounting going on. Departments/agencies routinely reprogram appropriated funds by notifying the responsible appropriations subcommittees. I don’t know what these notifications are called at DOD, but NASA calls them Operating Plans or Op Plans. The responsible subcommittee has a certain amount of time (some weeks) to review them. If the subcommittee does not object within that timeframe, then the Op Plan is approved and the department or agency moves forward with the reprogramming. Stuff happens (accidents, natural disasters, changes in foreign threats, changes in other policy or law, etc.), and appropriated budgets have to adjust.That’s different from what I was talking about. The STS budget (and I suspect SLS today) had substantial NASA infrastructure and overhead bookkept against it that had little or nothing to do with STS. This stuff was part of the agency’s annual budget request for STS to appropriators and the appropriators looked the other way (to the extent they even knew/cared). But that stuff really should have been broken out separately, justified on its own terms, and funding terminated (or not) accordingly.
We actually funded an X-33 history project by an objective historian...here is link:http://www.hq.nasa.gov/office/pao/History/x-33/menu1.htmCheers,Doug Stanley
Good to know, thanks. But to repeat my second question, does anybody know what the paper Cooper was referring to is, and is it the same as this, from an earlier post (#61):QuoteWe actually funded an X-33 history project by an objective historian...here is link:http://www.hq.nasa.gov/office/pao/History/x-33/menu1.htmCheers,Doug StanleyIf so, where can that history to be found now-link is dead ?
PRELIMINARY PROJECT DESCRIPTIONAndrew J. Butrica1 July 1997
MonographOriginally, one of the first major publications of the X-33 History Project was to be a monograph of under 100 pages on some aspect of the development of the X-33. The monograph would be limited in scope, appropriately illustrated, and accompanied by original documents in an appendix. When completed, the monograph would have been made available from NASA, as well as the X-33 History Project, through this home page.Instead of the monograph, however, the Historian, with the agreement of NASA, lengthened the draft monograph into a book-length manuscript. The book deals with the history of the DC-X, built by McDonnell Douglas for the Strategic Defense Initiative Organization's Single Stage to Orbit (SSTO) Program. It traces the search for reusable and single-stage-to-orbit launchers from early concepts to the creation of the SSTO Program to the transformation of the DC-X into the DC-XA as a NASA program, the first X vehicle in the space agency's new RLV Program.The book manuscript is now in a draft form and is undergoing review by various individuals, most of whom were involved in the history of the DC-X and DC-XA. The current plan is to see the manuscript published by the Johns Hopkins University Press in November 2003.

It was converted into a book by Andrew Butrica titled "Single Stage to Orbit", ISBN 0-8018-7338-X, 2003. I copied some pages from the Preface and Bibliographic essay which explains the monograph to book journey in more detail, attached.
Thanks for the good old website, it's a treasure trove !
Quote from: Spiceman on 07/17/2024 10:43 amThanks for the good old website, it's a treasure trove !Isn't it. I still wonder if the paper Cooper mentioned is subsumed into Butrica's book or now lost.
The reader thus will find throughout this work’s endnotes numerous references to records in the X-33 Archive. The archive includes an electronic guide to the files and their contents on CD.

I still wonder if the paper Cooper mentioned is subsumed into Butrica's book or now lost.Try at NARA catalog.archives.gov Per Butrica's book, page 258, we know NARA has the X-33 archives as 255-01-0645 where RG-255 is roughly "all NASA stuff". At page 247, there is a reference 41 to a memorandum by Henry F. Cooper to Rep. Murtha, File #291. Therefore, it is likely there are more memos by Cooper at NARA. EDIT: there is one thing that might make such a search easier. On page 258, Butrica says QuoteThe reader thus will find throughout this work’s endnotes numerous references to records in the X-33 Archive. The archive includes an electronic guide to the files and their contents on CD. In other words, there is a CD with a reasonable index of the X-33 material seen by Butrica. If someone has a copy then that might quickly answer your question above about Cooper's memo. Alternatively, maybe drop NARA a note and ask them for a copy of CD.
There are also 37 pages of comments in this thread. It is possible that some of the answers you seek are way up-thread.
Down into the rabbit hole... I've been learning about RLV / SSTO / TSTO since 2002, still finding new stuff. I have a few hundreds tech papers on my HD.
I'd have thought that by the mid-1990s it was perfectly obvious that not only had the Shuttle failed to make spaceflight cheaper and safer, but it wasn't even a step the right direction. Why did anybody think the right move was to once again attempt a big technological leap in the expectation that a safe, economic operational vehicle would quickly follow? It's as though the attitude was, "The Shuttle was too easy; let's build an SSTO!"

Rather suggests that Dan Goldin made them an offer they couldn't refuse (or at least posed Lockheed, MDAC and Rockwell a challenge they felt they couldn't not take part in) ?
