Perhaps the Young Astronauts organization has surrepticiously siezed control of the Net with a team of Teenage Whiz Kid Hackers and is now attempting to pump up its membership by broadcasting a statistically controlled stream of postings with the subliminal message: "If you don't join the Young Astronauts when you are Really Young, you'll NEVER get to space." The FBI should investigate the potential subversion of the Net by these insideous Hackers.

Office of Space Flight and Space Station employees at NASA headquarters were briefed on the formal consolidation of the two organizations yesterday. The newly formed Office of Space Flight is headed by Dr. William B. Lenoir. George Abbey will serve as deputy associate administrator. The space flight organization now includes four major areas: space shuttle, space station Freedom, space flight systems and human resources and institutions. NASA and Defense Advanced Research Projects Agency personnel at Dryden Flight research facility at Edwards Air Force Base are conducting taxi tests and a captive flight of the NASA-B-52/Pegasus air launched orbital booster today. The flight is the first of two that will qualify the project for its initial orbital flight mission. Video tape highlights of today's test will be broadcast over NASA Select TV at 4:00 p.m. ,eastern time, today. The Cosmic Background Explorer satellite...or COBE...is ready to be launched from Space Launch Complex 2-West at Vandenberg Air Force Base, Calif., November 17. A media briefing will be held at Jet Propulsion Laboratory next Tuesday prior to the launch. Both events will be broadcast over NASA Select TV. The Washington Times says a Maryland communications satellite company...CONTEL ASC...has sued NASA for $70 million, "charging that the Space Agency breached a 1984 contract to launch Contel's ASC-2 communication satellite on the space shuttle". The suit was filed in late September to recover the difference between the cost of a commercial and a shuttle launch. Final preparations for the launch of the DOD STS-33 mission November 20 continue at Kennedy Space Center. As on previous DOD missions, NASA Select Television will provide only launch and landing video of the event. Although a four hour launch period opens at 6:30 p.m., eastern time, the exact time of the launch is classified.

Apart from scientific reasons, it just may be cheaper. For a geostationary satellite you - need just one ground station with (maybe) cheaper design (=fixed dish) - can design near-automatic operations must easier - don't have to bother about eclipse periods that often (= less need for large battery capacity) This doesn't mean that things won't work in other orbits. Just look at Hipparcos, who was designed for geostationary orbit. Now we have much trouble here at ESOC to operate it, but basically it works. We just had to - get two more ground stations and equip them with the respective equipment - hire people for an additional night shift as all the nice automatic programs don't work any more, train them and make up a new operations plan - get all the money for these things :-) (that just the operations side I know of) Real nasties are only the eclipses (Hipparcos has to switch off a lot of things because of battery capacity) and the radiation belts. In a equatorial orbit you don't have to care about the radiation belts deteriorating your solar panels, but there you get atmospheric drag which may be a nuisance to high precision attitude keeping (Hipparcos' attitude has to be reinitialised much more frequently because of the disturbances at perigee).

It all boils down to the same old point: we're using state-of-the-art technology when we should be using *reliable* technology. Sorry to be cliche, but how long do you think it would take for the Soviets to dump a payload on a production Proton and boost it? And what are the odds of failure? I was reading an article in the Nov. Discover (hey, it was lying around, I couldnt help it.. :-) about the space plane, which they said would have lots of uses. Say the station needs an important part.... well, just fill er up with H2 and take off! No worries! They also compared the expected turnover time of " a few hours, or maybe days" with the "months" for the shuttle. I'll agree with months... but wait, was this how it was planned? What was the original turnaround for the shuttle expected to be... about a week, right? Does anyone actually think that the NASP, using virtually untried technology, will be able to be checked out and readied for flight in hours? Using scramjets and weird cooling systems, no less... Call me dubious.

All of you have given me a new hobby/interest (My wifes going to hate you for this). and also a special thanks to Larry Klaes. Larry, Tried to contact you through E-mail but It bounced three times! Your address is so long that my system truncated it (I think). But thanks for the in depth response to my "Antique Probes" questions. You can bet I'm going to take out most or all of those books! However, one thing you mentioned was Apollo 12 retrieving pieces from Surveyor 3. WOW. I never knew that. and for some reason I find it incredible that the navigation and guidance at that time could actually bring someone that close to a specific spot. Can you provide any datails as to WHAT PARTS?? or were their any PICURES of the Surveyor sitting there? Was this planned, or luck? Thanks again ------------------------------ End of SPACE Digest V10 #231 *******************
