Acronym List for sci.astro, sci.space, and sci.space.shuttle:
Edition 7, 1992 Aug 27
Last posted: 1992 Aug 6

This list is offered as a reference for translating commonly appearing
acronyms in the space-related newsgroups.  If I forgot or botched your
favorite acronym, please let me know!  Also, if there's an acronym *not*
on this list that confuses you, drop me a line, and if I can figure
it out, I'll add it to the list.

Note that this is intended to be a reference for *frequently seen*
acronyms, and is most emphatically *not* encyclopedic.  If I incorporated
every acronym I ever saw, I'd soon run out of disk space!  :-)

The list will be posted at regular intervals, every 30 days.  All
comments regarding it are welcome; I'm reachable as [e-mail].

Note that this just tells what the acronyms stand for -- you're on your
own for figuring out what they *mean*!  Note also that the total number of
acronyms in use far exceeds what I can list; special-purpose acronyms that
are essentially always explained as they're introduced are omitted.
Further, some acronyms stand for more than one thing; as of Edition 3 of
the list, these acronyms appear on multiple lines, unless they're simply
different ways of referring to the same thing.

Thanks to everybody who's sent suggestions since the first version of
the list, and especially to Garrett A. Wollman ([e-mail]),
who is maintaining an independent list, somewhat more verbose in
character than mine, and to Daniel Fischer ([e-mail]),
who is maintaining a truly HUGE list (535 at last count) of acronyms and
terms, mostly in German (which I read, fortunately).

Special Bonus!  At the end of this posting, you will find a perl program
written by none other than Larry Wall, whose purpose is to scramble the
acronym list in an entertaining fashion.  Thanks, Larry!
