The Hubble Space Telescope has been safely transferred to the payload bay of the orbiter Discovery on Launch Pad 39-B at Kennedy Space Center. Pad crews are checking electrical and mechanical connections today. On Sunday, a final check of telescope systems and instruments will be conducted. A suspect engine controller on main engine #3 was replaced yesterday. It will undergo a thorough test on Saturday. The Flight Readiness Review began today and will conclude Saturday afternoon. Analysis of data recorded by a Tiros-N weather satellite over the past ten years indicates there is no conclusive evidence of global warming from the so-called "greenhouse effect". Roy Spencer, of Marshall Space Flight Center, and John Christy, of the University of Alabama-Huntsville, conducted the research. Christy warned against misuse of the findings. He said at least another ten years of data are needed to make any valid scientific conclusions. The first stage of the Titan 3 booster that failed in its attempt to place an Intelsat 6 satellite into geosynchronous orbit has re-entered the atmosphere. The U.S. Space Command confirmed the rocket part either burned up or crashed into the Pacific Ocean, Wednesday morning. The upper stage remains in a tenuous low earth orbit while the communications satellite is in a safe 300-mile high orbit. Representatives from Intelsat and Hughes Aircraft met for a second time, earlier this week, with NASA engineers to discuss possible options to rescue the satellite. No decision has been made on a possible rescue effort. Preparations continue for the launch of the Pegasus winged rocket next Wednesday. Funded by the Defense Advanced Research Agency, Pegasus will be air-dropped from the wing of a NASA B-52 research aircraft over the Pacific Ocean. Its task is to place a 440-pound satellite called Pegsat into a circular polar orbit. Pegsat contains a very small experimental satellite that will be released, as well as an instrumentation package and two barium release canisters. Pegasus has been developed by Orbital Sciences Corp. and Hercules Aerospace. NASA Select TV will carry launch activities. ************* ----------------------------------------------------------------- Here's the broadcast schedule for Public Affairs events on NASA Select TV.

I have seen some posters around Cornell for an organization called the "United Space Federation". Nowhere on these posters does it say what the organization is or does. However, I did notice some interesting requirements for memebership: "(officers)...must attend at least two drills per month." "...must believe in and support the United Space Federation's mission, charter and take the oath of service." "...must provide color hair, color eyes, height, weight, skin tone (B, W, OTHER), age, sex, color photograph..." "...must sign a nondisclosure statement and take a legal and moral oath not to compromise or release information belonging to or about the UNITED SPACE FEDERATION its programs, members, officers, clients ..." Clients? Drills? Does anybody know anything about this charming organization? Who is backing it? What are they trying to do? When was the last time an organization asked you for your "skin tone"? I'm guessing that some skinhead group is trying to recruit idealists via the space program somehow. If you have any information, please EMAIL, as I can't read USENET when accounting is working on this machine. -- Paul Ciszek CISZEK@CRNLMSC2 W25Y@CRNLVAX5 Bitnet CISZEK@MSC2.TN.CORNELL.EDU W25Y@VAX5.CIT.CORNELL.EDU Internet "The trouble with normal is it always gets worse." -- Bruce Cockburn ------------------------------ Date: 2 Apr 90 20:10:43 GMT From: trident.arc.nasa.gov!yee@ames.arc.nasa.gov (Peter E.

The launch of the STS-31 space shuttle mission has been moved up to April 10. The decision was announced Saturday, following a flight readiness review by NASA managers, at Kennedy Space Center. Launch is scheduled to occur at 8:47 A.M., Eastern Daylight Time. Both shuttle and payload preparations were ahead of schedule allowing NASA officials to go for a launch two days ahead of the previously announced target date. Today at the launch pad, technicians are conducting a "confidence test" on the Hubble Space Telescope. Charging of telescope batteries has been underway since Saturday and will conclude Wednesday. A series of pre-launch briefings and the STS-31 mission will be carried on NASA Select TV. * * A reassessment of Space Station Freedom extravehicular activity requirements is scheduled for mid-April, according to Aviation Week magazine. Final results of the study are not expected to be completed until July. * * The air-launch of the Pegasus winged booster-rocket off the coast of California is scheduled for Wednesday. The Pegasus launch will be carried on NASA Select TV. * * Aerospace Daily reports Intelsat officials will determine, by mid-April, if rescue of the stranded Intelsat 6 communications satellite is feasible. * * The U.S. Air Force is scheduled to launch an Atlas-E on April 11 from Vandenberg Air force Base, Calif. Three small satellites will be placed in orbit. ************************* ----------------------------------------------------------------- Here's the broadcast schedule for Public Affairs events on NASA Select TV.

I just went to see FOR ALL MANKIND over the weekend, having heard about it for a while. In a word, you MUST see this movie. There are other good documentaries on the space program, and this is not the only movie that could have been made on the subject, BUT -- the impact of spending LOTS and LOTS of time on the moon, *on the big screen*, is stupendous. It gets to you in ways you may have forgotten you could be 'gotten' to. FOR ALL MANKIND is not a complete story -- there's certainly lots of omitted stuff -- but it is 'pure'. There's nothing in it that is not spaceflight. This has a nice cumulative effect. I saw it at the 57th Street Playhouse in NYC. It is worth a trip in from the tri-state area to see. The videotape will be worth owning, of course, but the big screen makes a difference. -- "DO NOT, repeat, DO NOT blow the hatch!" /)\ Tom Neff "Roger....hatch blown!" \(/ tneff@bfmny0.UU.NET ------------------------------ Date: 3 Apr 90 04:08:37 GMT From: agate!agate!web@ucbvax.Berkeley.EDU (William Baxter) Subject: Re: Shuttle Designs In article <9004021845.AA00131@ti.com> mccall@skvax1.csc.ti.com writes: >> agate!usenet@ucbvax.Berkeley.EDU (William Baxter) >> >Fact 1: The Shuttle is significantly bigger and has much more >> >delta-v capacity than the original design. >> The original 'design' was not well defined.

SPS is the positioning service for unauthorized (civilian) users of GPS and is implemented through the application of "Selective Availability", the purposeful degradation of the satellite ephemerides in the broadcast message and the dithering of the satellite clocks. The stated policy on SPS is that "... it is presently projected that a predictable and repeatable accuracy of 100 meters (3drms [the radius of a circle that contains at least 95 percent of all possible fixes that can be obtained]) horizontally and 156 meters (2 sigma) vertically will be made available ...". The NANU did not state that the degraded satellite ephemerides are restricted to the Block II satellites although it has been believed by the civilian community that this would be the case. If anyone detects SA on the Block I satellites, would they kindly let the poster of this message know. The NANU stated further that "... the constellation is still in the build up phase and is not expected to be declared fully operational until 1993. Any GPS users operating now do so at their own risk."
