What I meant to say..., was that for a useful program, it might make sense to have a free-flyer for materials science, do the SEI and biology on the manned station, and revive the OMV, which would now be rather necessary, unless you were going to use a shuttle for such work. This is thinking about what might be reasonalbe and useful, not what our oh-so-enlightened Congress has voted for or against... However given those parameters, I basically agree with you. However, A spun station section is essential to study the effects on various biological systems, including human, of lunar and martian gravities. It may be a neccessary part of Martian missions, unless MHD or NERVA engines are developed. It is worth researching, IMHO. ************************************************************************** Zeitgeist Busters!

The situation is equivalent to throwing a spanner away from a non-spinning station, i.e. an "impulsive" (instantaneous) velocity change. In this case, there is a very simple rule of thumb: the new orbit always passes through the point of the impulsive velocity change. So in general, the station orbit and the spanner orbit intersect at that point. The orbital periods will almost certainly be slightly different, so close approaches will be few. Relative velocity will be the same as the original separation velocity. I would not call this a serious hazard, compared to the hazard from orbital debris in radically different orbits. -- "I don't *want* to be normal!" | Henry Spencer at U of Toronto Zoology "Not to worry." | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: 17 Nov 90 21:53:51 GMT From: ubc-cs!news-server.csri.toronto.edu!utgpu!utzoo!henry@beaver.cs.washington.edu (Henry Spencer) Subject: Re: ELV Launch Loads In article <1576.27416B6F@ofa123.fidonet.org> Wales.Larrison@ofa123.fidonet.org (Wales Larrison) writes: > Does anyone remember the loads imposed by the Apollo launch >escape system? ...

I don't have details on tap, but as I recall, there was only one failure in a "real" test (there may have been some preliminary Little Joe tests without capsules, although I don't recall mention of such). In that one, the Little Joe malfunctioned badly just after launch, and the Apollo escape system triggered automatically and functioned perfectly. It wasn't quite the test that had been *intended* for that flight, but everyone was happy with the results nevertheless. -- "I don't *want* to be normal!" | Henry Spencer at U of Toronto Zoology "Not to worry." | henry@zoo.toronto.edu utzoo!henry ------------------------------ End of SPACE Digest V12 #574 *******************
