The one at Huntsville is a "test article", a pre-production prototype that was never considered flight-ready. (I've seen it, and read the signs on it carefully.) So one can argue that it wasn't a "real" Saturn V. The ones at KSC and JSC were the real thing, built for Apollos 18 and 19. -- If OSI is the answer, what is | Henry Spencer at U of Toronto Zoology the question?? -Rolf Nordhagen| uunet!attcan!utzoo!henry henry@zoo.toronto.edu ------------------------------ Date: 30 Apr 90 07:23:43 GMT From: fernwood!portal!cup.portal.com!MJB@uunet.uu.net (Martin J Brown-Jr) Subject: Project Solar Sail FYI, there is a (new?) paperback out called "Project Solar Sail", which is a collection of fiction, faction, and even some poetry dealing with interplanetary travel by solar sail ships. It was edited and with afterword by Arthur C. Clarke, and with an introduction by Isaac Asimov. This book is, also, is some small part (unclear at the moment, since I haven't finished it or skipped ahead) a fundraising volume for the World Space Foundation's Project Solar Sail. The book also contains a photo of Dr. Robert Forward's Starwisp, a microwave sail ship, on a hanger(?) floor. 75% of the written pieces have 1990 copyrights.

The space shuttle Discovery successfully marked a major milestone in space history by releasing at 380 miles above the Earth the Hubble Space Telescope. After initiating the orbit burn yesterday to return back, the shuttle continued its victory run home at over Mach 24 just after sunrise at 6:03 A.M. Pacific time. As the Discovery came into view over the California horizon, the speed reduced to mach 1 at 6:45 A.M.--finally touching down with ease at Edwards Air Force Base. Official landing time was on schedule at 6:49 A.M. Commander Loren Schriver and crew were in good spirits as they came down the stairs at 7:30. Now five days on its own, the Hubble Space Telescope is in full communication with the control center and out of safe mode status. Demonstrating the ability to recover from safe mode status once a situation was understood, analysts confirmed from the data recently dumped from two of the three onboard tape recorders what actually happened to the high gain antenna when it kicked into safe mode. As the high gain antennaes are technically healthy, the problem with high gain antenna number two was due to a simple cable in the way of free movement. Early this morning, the problem was reported to have been corrected. As engineers poured over the data, one control center engineer went to a toy store, purchased an assembly kit consisting of plastic sticks and joints building a model of the antenna gimbal assembly with the components and a piece of lamp cord. The team used the model to help visualize the problem. Analysis revealed that one of the components of the high gain antenna system was rubbing against the gimbal system power cable causing friction. This caused gimbal system torques to go beyond preset limits, triggering the spacecraft support systems computer to place the telescope in safemode. The anticipated new science to come once the Hubble is fully awake is what experts have in mind. The first possible time for light pictures will be approximately one week. The next in line of the great observatory series for launch this year include the Astro-1 payload on space shuttle Columbia planned for May 16 as well as the Gamma Ray Observatory scheduled for November 1. ******** ---------------------------------------------------------------- Here's the broadcast schedule for Public Affairs events on NASA Select TV.

Otherwise, I was told, a cow that made the mistake of licking the electric fence [cattle being unbelievably stupid creatures, one of the few who's IQ rises after slaughtering] would stand there with their tongues wrapped around the wire 'til it burned off. Looking back on it, that seems a trifle dramatic. I'd expect the cow just to cut the hell out of its tongue as it bolted from the fence, or *possibly* keel over from terror induced heart failure [and I can't say I ever saw a cow die from surprise]. In any case, the farmer would have to repair the hole in the fence the cow left, so the interupter saved money. For the animal lovers out there, cow fences don't pack all that much of a punch; I tried to swim under one across our creek and stood up too soon. Real surprising, but not incapcitating. I expect that Freedom's electrical system could charcoal broil someone unlucky enough to be part of a electrical circuit.

It is available for unlimited distribution. * STS-31 NEWS * =============== Mike (WD8KPZ) of Phoenix, Arizona reported hearing space shuttle astronaut communications on a frequency of 279.000 MHz AM during their EVA during the deployment of the Hubble Space Telescope. Mike used an Icom R-7000 receiver and a quarter-wave ground plane antenna at an altitude of 15 feet to receive the astronauts. * STS-35 NEWS * =============== The STS-35 Astro-1/SAREX mission launch date has been delayed from May 9 to May 15 due to the STS-31 launch delay. There may be a further delay due to a presently unhealthy STS-35 astronaut. * DOVE-1 NEWS * =============== Bob (N4HY) continues to upload software to the DOVE-1 satellite in an effort to bring it back "on line" after the OBC crash last month. DOVE-1 is presently transmitting on 2401.100 MHz (+/- Doppler!) while the 145.825 MHz general beacon is turned off. DOVE-1 will be back on VHF in a short while carrying digitized voice messages of world peace. * COMET AUSTIN NEWS * ===================== Comet Austin (1989c1) has been sighted by many living on the west coast of the United States in recent weeks. Comments from observers indicate that the comet was not as spectacular as expected and there are indications that the comet's brillance will decrease further now that it is receding from the sun. * CONSORT-3 LAUNCH * ==================== The launch of Consort 3, a commercial suborbital rocket carrying 12 microgravity experiments, has been set for May 17 at 10:40 AM EDT (1440 UTC), by the University of Alabama-Huntsville's (UAH) Consortium for Materials Development in Space (CMDS), a NASA Center for the Commerical Development of Space (CCDS). Consort 3 will be launched from the Naval Ordnance Missile Test Station facilities at the U.S. Army's White Sands Missile Range (WSMR), New Mexico, by Space Services, Inc., Houston, using its Starfire rocket. The rocket will carry the payload to an altitude of 200 miles and will provide the experiments with 7 to 8 minutes of microgravity time. [From: Peter E. Yee @ NASA Ames Research Center, Moffett Field, CA.] * MIR NEWS * ============ After numerous postponments, the 20 ton "Kristall" Mir expansion module is expected to dock with Mir on June 1, 1990. Software problems on board Mir are responsible for the delay. The module was orginally scheduled for launch in February. Cosmonauts Anatoly Solovyov and Alexander Baladin have been living on the Mir space station for 77 days. * SPACE FOR PEACE * =================== The European Space Agency and the Soviet Union have signed a ten-year agreement to cooperate on exploration and use of space for "peaceful purposes". Space Fax Daily reports the agreement was signed on April 23rd in Paris. There will be no exchange of funds under the pact which has the option to be renewed for an additional decade.
