October 5, 1992 (Phone: 202/358-1547) Jim Doyle Jet Propulsion Laboratory, Pasadena, Calif. (Phone: 818/354-5011) RELEASE: 92-164 ASTEROID'S ORBIT "CLOSES IN" ON EARTH One of the largest near-Earth objects, an asteroid named "Toutatis," will make a close Earth approach on Dec. 8, 1992, passing by at about 2.2 million miles (3.6 million kilometers) distance. Dr. Donald Yeomans, Head of the Near Earth Object Center at NASA's Jet Propulsion Laboratory, Pasadena, Calif., said the object, formally known as Asteroid 4179 Toutatis, passes Earth less than one degree above Earth's orbital plane every 4 years, making it an excellent object for study. The asteroid, at 2 miles (3.5 kilometers) diameter, is one of the largest to cross the Earth's orbit on a regular basis. Yeomans said the ground-based viewing conditions will be excellent for infrared optical and radar observations just before, during and well after the close Earth passage, and he notes that astronomers in many areas of the world simultaneously will study the body using several different techniques. Toutatis again will make close Earth approaches in 1996 and 2000. In 2004, it will come as close as about four Earth- Moon distances or about a million miles (about 1.6 million kilometers). Its orbit takes it almost to the distance of Jupiter's orbit before the sun's gravitational attraction pulls it back. The approach of Toutatis this year and the one in 2004 represent the two closest Earth passages of any known asteroid for the next 30 years, said Yeomans. Toutatis was discovered Jan. 4, 1989, by Astronomer Christian Pollas at Caussols, France, and was named after a Gallic deity called "protector of the tribe." - end - ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@kelvin.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |__ M/S 525-3684 Telos | Einstein's brain is stored /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | in a mason jar in a lab |_____|/ |_|/ |_____|/ | in Wichita, Kansas. ------------------------------ Date: 5 Oct 92 21:03:00 GMT From: University Space Society Subject: Controversy over V-2 anniversary Newsgroups: sci.space References: <4OCT199219005821@judy.uh.edu> <1ao4dsINNe1k@darkstar.UCSC.EDU> Sender: USENET News System Organization: University of Houston Lines: 33 News-Software: VAX/VMS VNEWS 1.41 Nntp-Posting-Host: judy.uh.edu Source-Info: Sender is really news@CRABAPPLE.SRV.CS.CMU.EDU Source-Info: Sender is really isu@VACATION.VENARI.CS.CMU.EDU In article <1ao4dsINNe1k@darkstar.UCSC.EDU>, bafta@cats.ucsc.edu (Shari L Brooks) writes... > >In article <4OCT199219005821@judy.uh.edu> >wingo%cspara.decnet@Fedex.Msfc.Nasa.Gov writes (in response to Mary Schafer's >post decrying the WWII actions leading up to the creation/manufacture of the >V-2): > [stuff deleted] >I fail to see how the actions of these others have any bearing whatsoever >on the actions Van Braun did or did not do whilst still in Nazi Germany. >If people, corporations or governments managed to get away with what some >would consider inexcusable crimes, that does not *excuse* the crimes of >those who were caught.

Like I said you missed the point. You deleted the part about concerning the fact that nowhere has Von Braun or any of the team outside of Arthur Rudolf EVER been accused of mistreating anoyone that worked for them. Arthur Rudolf who was was in a postition of authority at the Meittlework plant has been accused but no evidence has ever been brought forth to support the accusations. He was railroaded out of the US by the OSI by them threatening to take his NASA pension. If you are so concerned about this why do you not look at what the Israeli's have said about Rudolf which is that they are not interested because he was not involved in the mistreatment. Now if you want to keep this up either come up with some evidence that neither the US or Israeli government has or just shut up because you do not know what you are talking about.

I'd settle for another Korolev. Wernher spent one night in jail; Sergei spent years. Wernher made unprecedented advances in rocketry while working in two of the world's most technologically advanced countries. Sergei did too, working in a nation with a far poorer infrastructure. Granted, he had some A-4 technology to play with after the war, but so did the Americans. Coming from technologically behind, Sergei beat Wernher to the first satellite, the first man in orbit, the first woman in orbit, the first lunar flyby, the first space station, and other points in the "first" game. > In his life and his work he > was always dedicated to seeing mankind freed from this little dirt ball we live > on.

Excuse the hell out of me, but it has become apparent to many of the people on this board, myself included, that many people of a certian political mindset are needlessly condemning anyone who disagrees with their agenda as not caring about the enviornment. We do care about the enviornment. We just don't care too much about power. Or more appropriately, we care greatly about the absence of power. >What does bringing back dinosaurs have to do with such a critical >human dilemma as uncontrolled population growth. About the same as population growth has to do with 1992QB-1, which I personally would rather be reading about. >Persons who ecourage such >must either be quite ignorant of the future consequences or so insensitive >to the situation that reason eludes them. I would suspect that you are insensitive to the logic in Paul Dietz's posts, which argue that many of the problems currently attributed to overpopulation actually have other causes, independently of whether population is a problem or not; also that population growth varies inversely with standard of living, so raising people's (specifically the female people's) standard of living and expectation of treatment for themselves and their children would do a lot to slow down if not reverse population growth. You also seem to be insensitive to some of the real reasons for high fecundity: these people are only one or so generations removed from a time when you had to have a lot of kids, to insure the sur- vival of a few. As good medical services become more widespread, this ought to become less of a problem. >Rush Limbaugh was quoted recently as stating that population growth >was a "phoney" issue since if we move the entire world pouplation >as it exists presently, to the state of Texas the human density would >equal that of New York City.

I suspect you are because you can make a fool out of him and by proxy imply that Paul Dietz is a fool since they both have the same conclusion, even though they have different premises. I don't see you disputing Dr. Dietz's statements... I can send you some of them if you want. I have them on file. Then you will have to face the real issues, instead of the straw man you constructed from the admittedly satirical statements of a radio talk show host. Oh, I keep forgetting: actors and talk show hosts are supposed to be real experts on the enviornment these days, esp. if they agree with all the correct politicians... >Aside from the fact that Limbaugh is a pompus donkey;the truly frightening >part is he has so many mindless idolators in his ranks. Hell, I don't even listen to Rush. It isn't worth the trouble. Could you talk about the issues instead of personal attacks for once? I think I know the reason behind some of his satire, though: I guess he finds it really funny that people like you who think that only those 100 % in agreement with you *CARE* get upset about the things he says which are clearly satire. >Yes, if he had his way I'm sure Earth would become the planet Gideon.

I apologize if I am so close to flame on, regarding this subject, but unless and until some evidence shows up shut your yaps about Von Braun and war crimes cause you are talking in thin air. Every single conference on space development that I have been to in the last four years (and I have been to a lot of them) ends up with a cry in your beer session about how we need another Von Braun. In his life and his work he was always dedicated to seeing mankind freed from this little dirt ball we live on. I happen to know a number of the surviving Germans and each and every one of them have worked far beyond their retirements to continue to work for our planet having a space faring civilization. This committment to the good of mankind simply is impossible for those of a mind set that led to the deaths in the concentration camps. Until we gett someone in this business who is as committed as Von Braun was we will continue to sit on this dirt ball and cry in our beers and verbally stroke ourselves about our wonderful ideas about what NASA and Co or Private Enterprise and Co should do for space. If you really want to make a difference in the exploration and development of space make a lifetime commitment to it and work to build the corporation or work your way through government in such a way as to make it happen. This is what Von Braun and his team did. Von Braun and co could have left NASA or the Army many times and could have made a great deal of mony building ICBM's for the Air Force contractors but they did not. They worked and hijacked and shuffled funds to put a capability in place that allowed Kennedy to make his famous speech. It is funny that he made his speech only after the first successful firing of the F-1 engine, an engine program started in 1959. How many of you out there have that kind of character or commitment?

Measure the width of the radiators and the space between the modules and the rotary joints.... There is just enough clearance... Also...I guess you could make the truss smaller...but then the solar panels (which are also at the bare minimum for the minimum power reqs) would block essential antennas as well as have unnacceptable rotational limits... Frank, if you would like to debate detailed design issues email me... Those reading a debate of this nature would not know who to believe. My point in coming forward and giving my opinion on SSF was to offset the seemingly persistant negative press on the program.. I'd like to repeat my primary point....Space Station Freedom is a development program... It is not an end in and of itself. It will provide the integration of technologies necessary for PRODUCTION of manned space systems as in orbital platforms, and living environments..... Oh yeah...it will also provide us with a (hopefully) permanently orbiting facility which will house more experiments then those who are working on it can guess at... It'll provide consistent human viewing of the Earth.... It'll also give (the Japanese anyway) external experimental platforms for research outside... Lets try to stop being so negative about it! ------------------------------ Date: 6 Oct 92 00:06:41 GMT From: Henry Spencer Subject: what use is Freedom?
