In >other words, it took something of MAJOR PROPORTIONS to disrupt NASA's launch >capability. If Challenger were the only disruption, I would agree with you. However, the Shuttle has delayed or cancelled dozens of major payloads outside of the effects of the Challenger accident. More than half of Shuttle flights have been delayed more than a month within a year of when they were supposed to fly. One customer, Galileo, was delayed from early 1982 to late 1989, and its flight time delayed by 4 years, for a total of 11 year's delay. Would you like to wait 11 years for a seat on an airplane? The original flight rate promised to customers has been cut from 52 to 9 flights per year. The Shuttle has a long history of dictating, instead of serving, the customer. It remains as an example of why a nationalized space monopoly doesn't work. Many have learned the lesson; the major Shuttle customer, DoD, is now developing its own capability while the previous Administration had the wisdom put commercial payloads onto commercial rockets. As a result, we now have commercial Delta, Atlas, Pegasus, etc. that are provided launch services of unprecedented efficiency, reliability, quality, and above all attention to the customer's needs. -- Nick Szabo szabo@sequent.com "The biscuits and the syrup never come out even" -- Robert A.

Freedom would have long term >utility as a life science lab but not much as a microgravity facility. Gutsy perhaps, but no less rude and boneheaded for being so. Freedom in the proper configuration -- with an unmanned, free-flying platform -- would have served splendidly as a microgravity manufacturing base. NASA got Fred on the table in the first place as a platform for American leadership in space industry. Hundreds of talented scientists trained themselves in the exciting new fields of microgravity and vacuum science and manufacturing. By dumping the space manufacturing scientists NASA is not only ruining the careers of some of its most loyal customers, it is dumping its biggest program for generating new industry. LEO life sciences, on the other hand, is devoid of commercial or competitive utility, serving only as a buzzword for more astronaut entertainment. Once again, popular politics triumphs over national competitiveness. While our astronauts frolic and propose new multi-billion dollar toys for themselves, the Japanese and Europeans are building up solid databases of proprietary microgravity knowledge with less entertaining but more fruitful sounding rocket programs. The next generation of space industries now look like they will be dominated by Japan and Europe, despite the fact that the U.S. is spending so much more on our space program. NASA cannot dump such a big potential source of spinoffs and continue to pretend that it is a force in American technology. -- Nick Szabo szabo@sequent.com "The biscuits and the syrup never come out even" -- Robert A.

There's a lot of junk going on at NASA -- I know firsthand, having worked at a NASA center. There's also some great stuff, like Magellan and Mars Observer.

Hi! I am in search of a precise evaluation of the mean distance from the Earth to the first Lagrange point (L1), between the Earth and the Sun. This is needed to evaluate the lead time that would be provide by the "Windsock" satellite (actually in planning stage). This satellite would detect solar wind bursts, thus providing early warning about an incoming geomagnetic storm on the Earth. My own result is L1=0.00971*(Earth-to-Sun distance), i.e. about 1.45e+6 km (900,000 miles), but I have used a simple "circular orbit" model, and I lack the precise value of some parameters. Answers by e-mail are welcome: I will summarize in this group. ------------------------------ Date: 19 Apr 91 16:13:51 GMT From: dog.ee.lbl.gov!hellgate.utah.edu!caen!news.cs.indiana.edu!ux1.cso.uiuc.edu!usenet@ucbvax.Berkeley.EDU (Doug McDonald) Subject: Re: Atlas Centaur bites the big one, 4/18 In article <1991Apr19.055759.4781@nas.nasa.gov> ranma@noc.arc.nasa.gov (Robert Gutierrez) writes: >I wrote: >> Aside from the usual news reports, does anybody have any better details >> on the Atlas Centuar KSC self-destructed??? >> > >I'll bet those Arainespace launchings are looking better and better >every day to everybody else ... > > The folks who lost one to the Atlas had just finished losing one to Arianespace.
