Their animation of CM/LM separation showed LM legs still retracted (they were extended by then). CBS said the SM engine burn on lunar arrival was to keep the spacecraft from crashing into the moon; actually it was to change their free-return trajectory (return to earth if they do nothing) into a lunar orbit. And the balloons deployed by the CM on splashdown were said to be necessary for flotation (I think they were for stability indeed). Close enough for TV news, though.

Science had a good article early this summer about lots of this---only something like 30% of the actual time is it able to observe (that's 2628 hours per year), and this does not take into account moving it between observations, etc. also it is down some percent of the time for calibration and testing. all in all it would be much nicer to have an unmanned scope on the back side of the moon!

OK. $.02 times 240,000,000 (people) = $ 4,800,000. ...times 365 (days) = 1.7 billion dollars per year. Is this enough to design, build and maintain a space station?

It's good to be enthusiastic but you have to maintain your grip on reality also. The fact is that there are many small companies with various indep- endent space projects going as we speak. One of them performed a successful suborbital launch only a few months ago. And wealthy enthus- iasts have not exactly been beating down their doors to invest. Now the conspiracy fans among us will say that this is due to all the restrictive laws that NASA and the rest of the government have placed in the way. But if there really is so much enthusiasm out there for a commercial space program then surely there are millions of voters who are hopping mad about those laws and who will happily vote-in congress- critters who will change those laws. Guess what? There is no such enthusiasm. The average American doesn't give a farthing about space, or science, or anything else having to do with the future. Daniel says 'nothing' will discourage him. Clearly he has never heard of 'economics' or 'politics'. ---Peter ------------------------------ Date: 31 Jul 89 04:59:04 GMT From: portal!cup.portal.com!PLS@uunet.uu.net (Paul L Schauble) Subject: Re: Henry's (not Weinhards) >You are staring democracy right in the face. Which is why the authors of the Constitution did NOT make this country a democracy. John W Campbell used to say that there has never in the history of the world been a democracy that lasted 100 years, and that the US would not be the first. Depending on you viewpoint, the US became a democracy either in 1906 or 1964. I tend to believe 1964 myself. ++PLS ------------------------------ End of SPACE Digest V9 #601 *******************
