Which is the point. A reengineered Saturn V is not a "Tried and true" system and doesn't just get stuck on the pad and launched. If we had the lines intact, great. BUT WE DON'T!

Some people _are_ too dumb to vote. But there's no reason to be so harsh about it. I support a version of elitism that has no economic or social requirement, only one in the intellectual side: you can tell what's wrong with the nation & have a feasible solution to solve it. Also, no dogmatists allowed-i.e. no evangelicals, because in their case, mind is submissive to religious fervor & claptrap.

I am into Image Processing Planetary Geology as well as Astronomy. However People's Net 51 does not have ftp access, as it is only a mail system. Does anyone have or know of a node here in the Minneapolis/St.Paul area that I could log into via modem and access these files? I appologize for not knowing how to limit posting to the tri-state area yet. I would have to read about 400 messages and maybe still not find out. If anyone wants to tell me how to do that as well, please go ahead. E-mail is fine if you don't want to use up bandwidth - esp on the last one. I use an Atari ST w one meg and the AIM image processor from the Delft Institute of Technology in the Nederlands. If anyone has any conversion prgs that could take the JPL and postscript formats and convert them to Amiga .IFF, Macintosh screen dump, Degas, Spectrum 512 or even GIF I would *really* like to have that.

N89-66 NOTE TO EDITORS: UPDATE ON ATLAS CENTAUR-68/FLTSATCOM LAUNCH NASA has decided to resume launch preparations for the FltSatCom Navy communications satellite. The Atlas Centaur rocket, AC-68, is now scheduled to lift off from Launch Complex 36 on Monday, Sept. 25, at the opening of a launch window that extends from 4:12 a.m. to 4:42 a.m. EDT. Air Force and National Hurricane Center weather forecasters have provided a cautiously optimistic forecast about the effects of Hurricane Hugo on the Cape Canaveral area. Plans are in place to cease launch preparations and take appropriate precautions should the weather picture change. The pre-launch news conference for AC-68 is scheduled for 11:30 a.m. EDT on Friday, Sept. 22. The briefing will be carried by NASA Select television on Satcom F2-R, transponder 13. Audio only is also available on the V-2 circuits, which may be dialed directly at 407/867-1220, -1240 or -1260. News media representatives wishing to attend the briefing should be at the KSC News Center by 10:45 a.m. for transportation to the E&O building on Cape Canaveral Air Force Station. Those needing accreditation should call the KSC News Center at XXX/YYY- ZZZZ to arrange for badging. Remote camera set-up for launch will be on Sunday, Sept. 24. Transportation to the pad will leave the KSC News Center at 4 p.m. EDT. On launch day, media representatives covering the launch may obtain badging at the Gate 1 Pass and Identification Building on Cape Canaveral Air Force Station from 2:45 a.m. until 3:15 a.m. EDT. All media then will be escorted to Press Site 1 on Cape Canaveral Air Force Station. ------------------------------ Date: 21 Sep 89 00:30:45 GMT From: trident.arc.nasa.gov!yee@ames.arc.nasa.gov (Peter E.

I remember, tho, that the narrator said: "Most scientists believe that Mars doesn't *have* an atmosphere!" --CNN News narrator trying to stick it to D. Quale A couple of days later, there was another piece on an int'l group who are in the Midwest, apparently to learn more about how land surface conditions (e.g. hugh tracts of soybeans) affect the local weather. The narrator said that they were there in order to: "learn how the planets affect the weather." --CNN Newsreader explaining science to his listeners I called CNN about the pieces. I could feel the blank stare the woman the listening must have had on her face. W.r.t. the last piece, I tried to get thru to her by emphasizing "Only an *astrologer* would say that planets affect the weather." Her reply? "No, you mean *astronomer* !"

Yee) Subject: Magellan Status for 09/19/89 (Forwarded) Magellan Weekly Status Sept. 19, 1989 This is a weekly Magellan status report. Spurious interrupts were experienced on four of the seven daily attitude update star calibrations (Starcals) performed last week. Three of the four Star Scanner Unit calibrations also experienced spurious interrupts. All reaction wheel desaturations were nominal. On Sept. 13, the spacecraft was maneuvered from Medium Gain Antenna (MGA)-to-Earth to High Gain Antenna (HGA)-to-Earth attitude to playback Starcal data so that analysts can investigate Star Scanner Unit magnitude telemetry to gain additional insight into the spurious interrupt problem. The spacecraft continued to cool slightly after the MGA offpoint maneuver at the beginning of the cruise 10 load. The solar panel offpoint rotation test for 4.5 hours was accomplished on Sept. 15 to reduce the energy passed through the shunting system. First indications are that this did have some effect on several components. The Attitude and Articulation Control Subsystem (AACS) memories were partially read out on Sept. 14 and memory verification was accomplished on Sept. 15.
