Yee) Subject: NASA Headline News for 09/20/89 (Forwarded) ----------------------------------------------------------------- NASA Headline News Wednesday, Sept. 20, 1989 Audio: 202/755-1788 ----------------------------------------------------------------- This is NASA Headline News for Wednesday, September 20..... As Hurricane Hugo continues to move in a northwesterly direction towards the U.S. East Coast, Kennedy Space Center launch officials have decided not to make a decision yet on moving the Space Shuttle Atlantis back to the Vehicle Assembly Building. Launch Chief Robert Sieck says that KSC will maintain a posture to allow for a 24 hour move, but personnel are continuing launch processing activities. There are indications the storm will come ashore well north of the Cape Canaveral area. But, as part of contingency plans, the Solid Rocket Booster on Mobile Launch Platform-3 was removed yesterday and the platform itself moved out of the Vehicle Assembly Building to make way for the STS-34 stack, if necessary. Meanwhile, launch officials have made a tentative decision not to demate the FltSatCom satellite from the Atlas-Centaur booster at the Cape. The launch has been slipped to no earlier than Sunday at 4:13 A.m., Eastern time. The Virginia Attorney-General has asked the Circuit Court in Richmond to order the immediate shutdown of the Avtex fiber plant in Front Royal. The plant produces high quality rayon yarn used in NASA and DoD solid rocket motors. The state contends the Avtex plant is the source of highly toxic PCBs that are allowed to flow into the Shenandoah River. The Washington Post says the court will hold a hearing on the request tomorrow. The plant is the sole producer of the rayon yarn in the United States. The Senate has completed debate on the bill that contains the NASA FY 90 appropriations. Senators are expected to vote on the measure today. The $12.3 billion money bill contains $1.85 billion for Space Station Freedom. The House version of the NASA appropriation allows about $1.65 billion for the station. That and other differences in the bill must be worked out in a House-Senate conference in the near future. And a Landsdale, Pennsylvania, student has been named winner of the Space Station Freedom experiment proposal competition. Diane Fogel was awarded a $3000 scholarship and a personal computer at a space science student involvement program meeting in Washington this past weekend. * * * ----------------------------------------------------------------- Here's the broadcast schedule for public affairs events on NASA Select TV (GE SatCom F2R, Transponder 13).

Thanks to the many people who e-mailed me the answer. Heat from radio-isotope decay and thermo-couples. No moving parts.

I thought that they >were still pretty much custom built... Well, bear in mind that there were only 15 built. However, within the limits of that, they were well advanced in the transition from prototypes to production. For example, the first few were built at Marshall by a mixed contractor/NASA team, but the last few mostly came from contractor plants. Remember that the planning was based on a much longer production run -- it made sense to try to move towards production-line techniques as soon as possible, even though in hindsight this was pointless. -- "Where is D.D.

Public Service Announcement FOR SALE: THE LOST RUPPELT PAPERS THE 35 TO 40-YEAR-OLD SECRET, HIDDEN PERSONAL PAPERS OF CAPTAIN EDWARD J. RUPPELT (OF PROJECT BLUE BOOK FAME) Sellers: Researchers Robert B. Klinn and David Branch (authors of "The Continuing UFO," the 1970's weekly investigative columns in The Orange County Register and The Anaheim Bulletin) Captain Edward J. Ruppelt's "The Report On Unidentified Flying Objects," published in 1956 by Doubleday, stood as a monument of candor and honesty in research at a time when Government UFO activities were shrouded in secrecy. Ruppelt had briefly pulled aside the curtain of secrecy, revealing UFO sightings and pro-UFO official documents previously unknown to the public. Early UFO writer Max B. Miller summed up reactions of many readers of Ruppelt's UFO book: "A feeling of 'At last the truth!' surges within the reader." In that book, Ruppelt had dared to present unsolved UFO cases that challenged science's and the Government's UFO stance of the 1950's. And he had done it years before J. Allen Hynek made known his real UFO views, before the Freedom of Information Act, before there was a NICAP or a MUFON, before physicist James E. McDonald's significant UFO research, before the controversy about MJ-12, and before UFOlogists became aware of "disinformation." Now after 20 years, the 35 to 40-year-old papers and notes that Ruppelt used in the preparation of his all-time classic book, as well as other documents prepared by or belonging to Ruppelt, are being made available for purchase. Invaluable for research purposes are cases edited out of the original manuscript and never published. Preventing imminent destruction of these files, in 1969 researchers/columnists Robert B. Klinn and David Branch purchased from Mrs. Edward J. Ruppelt the complete original papers, constituting several boxes of material. These priceless personal papers of Captain Edward J. Ruppelt include: -- A file marked "Not For Publication Under Any Circumstances," in which Ruppelt sets down the involvement and views of certain key UFO officials and individuals such as Dr. Donald Menzel. The late Dr. J. Allen Hynek, after finding this file among all the others in this collection, stated, "This is worth the price of admission." That file has been seen only by Hynek and the owners of the Ruppelt papers. -- A complete, original [carbon], unedited, unexpurgated manuscript of "The Report On Unidentified Flying Objects" with information not included in the published book. An example of material this manuscript presents is a reference to a UFO intelligence agency so secret that Ruppelt writes that if he named it, it would not be recognized. However, he writes, it was headed by a renowned scientist. -- A file compiled by Ruppelt detailing many UFO reports. -- Personal letters written to Ruppelt, including at least one official military/[AF] letter denying Ruppelt key material for a followup book. -- An unpublished report by Ruppelt on UFO contactees. There are also intriguing and revealing quotes by highly placed individuals in the intelligence community, including candid remarks by General Cabel, a high ranking official in the CIA, who says, with respect to the situation on UFOs, "I've been lied to! I've been lied to!" (What would a man with that attitude about UFOs and that position of power in the CIA then likely do to investigate UFOs?)
