Is attitude control even necessary for small satellites? Also, is thermal control strictly passive, or are there heaters on board your spacecraft? Thanks! -- Steve Derry <s.d.derry@larc.nasa.gov> ------------------------------ Date: Tue, 23 Nov 93 07:07:04 PST From: portal!cup.portal.com!Larry_L_Ledlow@uunet.uu.net Subject: MIR Packet frequencies? To: ham-space@ucsd.edu Mir packet is on 145.55 MHz. 1200 baud AFSK. The call is R0MIR-1. You'll occasionally hear thecosmonauts working FM voice on this freq. This usualy happens Friday/Saturday nights when they have some spare time. 73s, Larry na5e@genie.geis.com ------------------------------ Date: 24 Nov 93 16:56:59 GMT From: microsoft!wingnut!laurahal@uunet.uu.net Subject: Satellites and Frequencys To: ham-space@ucsd.edu Shameless plug: you can get all this information and lots more from AMSAT.

THIS LIST DEPENDS UPON THE KIND DONATIONS OF ITEMS FROM PEOPLE ON THE NET. We're back! Sorry about the delay folks, but this was due mainly to my excruciating workload for the past few months. I let even the reminders lapse so we haven't had much new Trivia for awhile, although last weeks reminder prompted a few messages. They'll appear in the next update. I'm posting the full list with this update, just to remind you how many items we have collected now. I would appreciate corrections of any kind and SUBMISSIONS galore! This list is now available via anonymous ftp from the following sites: krakatoa.jsc.nasa.gov as /misc-docs/trivia.txt ames.arc.nasa.gov as /pub/SPACE/MISC/trivia.txt If at ANY time you want the latest update on the trivia list, then it will be at one of these sites. I will be updating the complete list to these sites each time an update appears in the newsgroups. The news distribution of this file is now:- sci.space sci.space.shuttle sci.astro rec.radio.amateur.space The last group will only be included when there are new items of trivia are related to amateur radio in some way.

[Guiness Book of Records, 1992 Softcover edition.] (270) The first double quasar (0957+56) among 1500 known quasars was announced in May 1980. [Guiness Book of Records, 1992 Softcover edition.] (271) The Nearest star to Earth, excepting the Sun, is the very faint Proxima Centauri, discovered in 1915, which is about 4.225 light years away. [Guiness Book of Records, 1992 Softcover edition.] (272) The nearest star visible to the naked eye is the binary Alpha Centauri or Rigel Kentaurus at 4.35 light years distant. [Guiness Book of Records, 1992 Softcover edition.] (273) The Alpha Centauri binary will reach a minimum distance from Earth of 2.84 light years in the year 29700 AD. [Guiness Book of Records, 1992 Softcover edition.] (274) The present distance of the Solar System from the centre of the Milky Way galaxy is 27 700 light years and it will reach a minimum distance of 27 600 light years (perigalacticon) in about 15 million years' time. [Guiness Book of Records, 1992 Softcover edition.] (275) The AVERAGE velocity of the Sun and nearby stars has been calculated to be 792 000km/h. However, the Sun's actual velocity is 97 200km/h faster than this average. [Guiness Book of Records, 1992 Softcover edition.] (276) The largest known star is Betelgeux at 310 light years distance, and is 500 times larger than the Sun. [Guiness Book of Records, 1992 Softcover edition.] (277) The heaviest known star is Eta Carinae, 9100 light-years distant in the Carinae Nebula in our own Galaxy. It has a mass some 200 times our own Sun. [Guiness Book of Records, 1992 Softcover edition.] (278) The smallest known star appears to be the White Dwarf L362-81 with an estimated diameter of only 5600 km. [Guiness Book of Records, 1992 Softcover edition.] (279) The lightest and dimmest known star is RG 0058.8-2807, with a mass of only 0.014 that of our Sun, and a total luminosity of only 0.0021 that of the Sun. [Guiness Book of Records, 1992 Softcover edition.] (280) The brightest Supernova ever seen by historic Man is believed to be SN 1006, noted in April 1006 near Beta Lupi. It f;ared for two years and attained a magnitude of -9 to -10! [Guiness Book of Records, 1992 Softcover edition.] (281) The largest constellation is Hydra which covers 6.3% of the hemisphere and contains 68 naked eye stars. [Guiness Book of Records, 1992 Softcover edition.] (282) The constellation Centaur, ranking 9th in area, has at least 94 naked eye stars. [Guiness Book of Records, 1992 Softcover edition.] (283) The smallest constellation is Crux Australis with an area of only 0.16% of the whole sky.

I think it was Crippen. Apparently all John Young heard was this "Whoosh AHHHHHH!!!!!". There is a fan in it to suck down the contents. Apparently the fan was verified to be working correctly (i.e. it spun up) but nobody ever checked to see if it sucked or blew... [From HOLLIS@TITAN.KSC.NASA.GOV] (2) When trying to find a way to keep the water out of the parachute compartment after splashdown, scientists ended up using a product from a drug store. I saw this on a space travel special. The story goes something like one of the project scientists sons was up with a cold. So, the scientist mixed up a cold remedy gel (added water to a powder) for his son late one night. This gave him the idea. When itemizing the inventory for the project budget, they used the drug store product code and used a backwards spelling of the product name. Of course, they adapted it a bit for the spacecraft, but the same principle of this gel was used. [mark.blevis@qmail.dgrc.doc.ca] (3) Supposedly, one shuttle launch was delayed due to a rare bird nesting in the launch pad gantry. Does anyone know if this is true and if so which launch ? (According to the guide on a KSC coach tour - probably not the most reliable of sources 8-}) [Mark Grant <mark@isltd.insignia.com>] (4) The Demise of Blue Streak and ELDO put paid to plans laid in 1968 to launch leeches - 'the world's most ideal space travellers' - on an extended flight. "Give them a bloody meal before they go, and they'll need nothing for a year-and-a-half!" was how one scientist characterized the suitability of leeches for space travel. Posing no feeding or waste disposal problems, leeches might even breed en-route - providing researchers with a useful insight into the genetic side- effects induced by exposure to radiation in space. (5) In some respects, Neil Armstrong was fortunate to become the first Moonwalker. In 1963, his place in the history books was under seige from a chimpanzee named Howard! After just one year of study at the US Space School, Howard had broken the world's land speed record in a rocket propelled sled, and had been banned from playing noughts-and-crosses with visitors because he usually won! The chances are that if a monkey had been selected to fly to the Moon instead of a man, it would have been Howard. (6) Under the direction of NASA's Ames Research Center in California, a study was conducted into the viability of employing a 'vacuum cleaner' type device in Low-Earth orbit to collect some of the particles of Moonrock (tectites) that are dislodged from the lunar surface by annual meteorite showers and sometimes find their way to the Earth's surface. Collected in orbit and returned to Earth by parachute, samples gathered in this way would be free from the contamination caused by passage through the Earth's atmosphere. (7) In reference ot item 64 in the trivia list, Is the reason given true? 1978-1986 the rumor was that if ejected at 100 Kft then you would drift up to 200 Kft before falling back. During the fall, the aero heating would become so intense that helmet melting would be likely. I'd love to know real reason the 100Kft limit was enacted.
