Additionally, the article stated that only when production reached the 300,000 unit per year rate, which has recently happened, would GM make a profit on a per unit rate. According to an Earlier Space News article, using the 500 million per launch figure is only correct when you add the infrastrucure costs incurred by the TDRSS system and the worldwide ground support for that system. Which by the way DC will have to pay for as well. Interestingly enough NASA is making money right now on excess TDRSS capacity by marketing it through Columbia Communications corp. It is roumoured that this money will be in the 50 million per year range for NASA within a couple of years. Nice little offset to lower the overall cost of the system. So your tired old argument about people being thrown in Jail for these accounting methods is as false now as it ever was. Market presence is the buzzword here and space is the ultimate market to be present in.

FBIS is the Foreign Broadcast Information Service which is done by the CIA, gets all kinds of foreign radio, television, etc. broadcasts which is of an informational nature and translates it. They've been doing it since just after WWII according to a book I read recently. Apparently JPRS does the same thing with print media. Together they put it all in either daily or periodic reports. The Dept. of Commerce, National Technical Information Service sells them to anyone. They cover many countries and many topics mostly of political and technological nature. NTIS has a nice catalog of these products. See below for excerpt from their catalog. For about $75 a year you can subscribe to the "JPRS Report: Science & Technology: Central Eurasia: Space" and get most of the significant articles on space subjects published in the CIS from newspaper and TV news to technical journals. Its published about every 2-3 months according to when they can fill up 50 or so pages. I kind of wish they would do the same for the USA... BTW: NTIS says they are funded only by the sales of the reports but I doubt that includes the cost of gathering or translating...

It was the motivating factor behind Steve Jones' experiments, as is clearly demonstrated in the literature. After demonstrating scientific break even with muon-catalyzed fusion and proving that muon-catalyzed fusion is (just barely) a no-go for energy production, he also published a paper estimating 'cold' fusion rates under other conditions of geological interest and later was led to electrochemistry. On a separate point, to clarify something I wrote that Dale Bass commented on, I did not mean to imply (by an unfortunate juxtaposition of two sentences) that fusion in the Pd-D system might be muon catalyzed. It is (purportedly) electrochemically induced. Muon catalyzed fusion is best done under very different conditions and most experiments on the Pd-D system take care to monitor cosmic rays so they can be either vetoed or gated as one desires. -- J.

For the record, I have never stated to the net or to Dennis any opinion as to why Comet failed. No, I don't think it's because of STS but rather because Westinghouse wasn't up to the task. >They were given a contract for the amount of money that they asked for and >they could not even get the first mission off the ground even when they >spent 85% of the money for all three missions before it was terminated. By and large true. Commercial procurement isn't a panacia which will solve all our probelms. It is only a necessary part of the solution. >> ON orbit Manned experiments.

A valid one according to my research. We are now looking at TWO repair missions upping the total cost to well over $1B. If we assume that HST was a typical project, then according to the recent assessment done by NASA of their procuremnt, then another HST could be had for far less than $400M which causes launching on Titan with a new HST to win hands down.

Pat, then people like you bitch about how much of a waste it was to buy all that hardware we didn't use. Of course, you're taking the discussion down the "ACRV" road, rather than address the specific problems involved with the funding mechanisms as they are set up now. But thank you for pointing out that YES, this is a $2.1 billion/year program which may or may not end up to $20 billion.

They took the quickest way back, which is completely understandable. To do this, they had to put themselves back on a free return trajectory since, as you point out, they weren't on one (in order to reach their planned landing site, Fra Mauro). But there's no reason on or off earth they would have used fuel to slow themselves into lunar orbit when it could be used to get them back more quickly, and I recall that the return trip was shortened by a day by firing the LM engine some time after the lunar pass. I believe the last straw that caused the explosion was turning on some heaters to "stir" the liquid oxygen. -- Chris Jones clj@ksr.com ------------------------------ From: wingo%cspara.decnet@Fedex.Msfc.Nasa.Gov Newsgroups: sci.space Subject: Re: DC-X Prophets and associated problems Date: 27 Jul 1993 14:07 CDT Organization: University of Houston Lines: 76 Sender: University Space Society Distribution: world Message-Id: <27JUL199314073663@judy.uh.edu> References: <22u3n0$sor@access.digex.net> <230k8o$enm@voyager.gem.valpo.edu> <233jhr$iss@access.digex.net> Nntp-Posting-Host: judy.uh.edu News-Software: VAX/VMS VNEWS 1.41 Source-Info: Sender is really news@CRABAPPLE.SRV.CS.CMU.EDU Source-Info: Sender is really isu@VACATION.VENARI.CS.CMU.EDU In article <233jhr$iss@access.digex.net>, prb@access.digex.net (Pat) writes... >In article <230k8o$enm@voyager.gem.valpo.edu> mjensen@gem.valpo.edu (Michael C.

Wrong. COMET is a glaring example of how badly you can screw up a "commercial" mission. Allen's pat reply that it failed because of STS does not hold water. They were given a contract for the amount of money that they asked for and they could not even get the first mission off the ground even when they spent 85% of the money for all three missions before it was terminated. > > ON orbit Manned experiments.

Sometimes you say some good things, BUT your total outsider perspective shows very clearly that from a systems perspective, that is looking at the problems from all angles, your analysis is often at best incomplete.
