When you have a political set up where you axe either Fred or space science, I think it is safe to say a zero-sum game is going on. ----------------------------------------------------------------------------- Jim Bowery 619/295-3164 The Coalition for PO Box 1981 Science and La Jolla, CA 92038 Commerce ----------------------------------------------------------------------------- ------------------------------ Date: 24 May 91 06:57:09 GMT From: cis.ohio-state.edu!zaphod.mps.ohio-state.edu!rpi!cook@tut.cis.ohio-state.edu (Cathi A Cook) Subject: Re: Babies in Space gwh@headcrash.Berkeley.EDU (George William Herbert) writes: >In article <12947@sybase.sybase.com> brook@alf.UUCP (brook mantia) writes: >>In article <9551@suned1.Nswses.Navy.MIL> lev@slced1.nswses.navy.mil (Lloyd E Vancil) writes: >>>Yes reduced gravity should cause problems for pregnancies and growing >>>children >>Why?

Especially what would happen to its bone strucutre... No scientific references here, but just a thought on pregnancy itself. Pregnancy relies heavily on gravity (pun not intended) for lots of things. One that springs immediately to mind is proper orientation of the fetus; ie. head down position. Any woman who has ever been pregnant can tell you that the fetus can find its way into many uncomfortable places even with gravitational constraint. My first emotional reaction at the mention of zero-g pregnancy was "OUCH!!!!"... Also, I think there might be some problems with the pooling of fluid in the tissues...I don't know how much placental blood flow relies on gravitational cues, but I'd be willing to bet that it's a nontrivial amount. >-george william herbert -rocker ------------------------------ Date: 25 May 91 00:10:09 GMT From: news-server.csri.toronto.edu!qucis!akerman@uunet.uu.net (Richard Akerman) Subject: Re: Asteroid mining In article <1991May21.193331.16008@zoo.toronto.edu> henry@zoo.toronto.edu (Henry Spencer) writes: >In article <1991May21.150342.18827@watdragon.waterloo.edu> jdnicoll@watyew.uwaterloo.ca (James Davis Nicoll) writes: >> The Sudbury asteroid has two advantages that allow it to produce >>nickel at a lower cost than nickel produced by exploiting other asteroids. > >Just to nit-pick: it is not in fact clear that the Sudbury mines are mining >an asteroid.

Just to doubly nit-pick: The Sudbury Igneous Complex is the result of two impacts, one leaving a 140 km crater dated at 1.8 Gyr, the other 9 km crater dated at 35 Myr. Also, remember that the iridium anomaly is noticeable because asteroids are enhanced in platinum group metals relative to the Earth's crust (the PG metals, being siderophilic ["iron-loving"] have sunk down and alloyed with the Earth's core). Platinum group metals include, of course, platinum, and also I believe gold.

(was: Re: Ethics of Terraforming) / hpfcso:sci.space / will@rins.ryukoku.ac.jp (will) / 7:08 pm May 16, 1991 / Perhaps the Japanese can offer something here. Acually the Japanese are very good at thinking about their future. When Admiral Perry came to Japan over 100 years ago the Japanese at that time realized that it was best to think about the future than to fight America. They did'nt think about 5, 10, 50 years into the future. These quys where thinking in terms of generations and hundreds of years. And as a result of this thinking are now a World class economic power. Just to quote Mr. Morita of Sony: "U.S. managers are often criticized for their short-term outlook, supposedly forced on them by Wall Street". (Morita recalls a chat with a money trader in New York) "I enquired how far ahead he looks, One week?, "No, No" came the reply. "Ten minutes." was the answer. If Americans think only in terms of 10 minute action, while we Japanese think in 10-year terms, America assuredly faces gradual decline". Respectivly, if mankind (as a hole, not just America) does not change it way of thinking about the future, then all of the grand plans of inhabiting our solar system or what-ever will also face disaster. By the way, the Japanese are changing. I was surprised by one of my students that ask me to listen to an Joke about America. Here is how it went: What is the difference between England and the Philippines? nothing. What is the difference between America and the Philippines? The number of whores. I personally did'nt share his enthusiasm of this being funny. So I asked him where he heard this and his friend a Kyoto Univ. had told him of it. Talking about America in decline. The Japanese seem to think so. Will..... If the Japanese are thinking so far into the future, perhaps you can explain why they are destroying the tropical rainforests of Southeast Asia in order to make things such as disposable chopsticks... Japan, IMHO, faces some very serious problems in the near-term future unless they are willing to submerge their general xenophobia, open up their markets to other countries, and stop wasting the talents of half of their citizens: their women. Japan is facing a severe labor shortage and a very rapidly aging population. Japan is not necessarily the economic superpower of the 21st century that everyone seems to blithely assume. ------------------------------ End of SPACE Digest V13 #634 *******************
