    FREQUENTLY ASKED QUESTIONS ON SCI.SPACE/SCI.ASTRO

    INTRODUCTION

    This series of linked messages is periodically posted to the Usenet
groups sci.space and sci.astro in an attempt to provide good answers to
frequently asked questions and other reference material which is worth
preserving. If you have corrections or answers to other frequently asked
questions that you would like included in this posting, send email to
leech@cs.unc.edu (Jon Leech).

    If you don't want to see the FAQ, add 'Frequently Asked Questions' to
your KILL file for this group (if you're not reading this with a newsreader
that can kill articles by subject, you're out of luck).

    The FAQ volume is excessive right now and will hopefully be trimmed down
by rewriting and condensing over time. The FAQ postings are available in
the Ames SPACE archive in FAQ/faq<#>.

    Good summaries will be accepted in place of the answers given here. The
point of this is to circulate existing information, and avoid rehashing old
answers. Better to build on top than start again. Nothing more depressing
than rehashing old topics for the 100th time. References are provided
because they give more complete information than any short generalization.

    Questions fall into three basic types:

    1) Where do I find some information about space?

    Try your local public library first. The net is not a good place to ask
    for general information. Ask INDIVIDUALS (by email) if you must. There
    are other sources, use them, too. The net is a place for open ended
    discussion.

    2) I have an idea which would improve space flight?

    Hope you aren't surprised, but 9,999 out of 10,000 have usually been
    thought of before. Again, contact a direct individual source for
    evaluation. NASA fields thousands of these each day.

    3) Miscellanous queries.

    These are addressed on a case-by-case basis in the following series of
    FAQ postings.


    SUGGESTIONS FOR BETTER NETIQUETTE

    Read news.announce.newusers if you're on Usenet.
    Minimize cross references, [Do you REALLY NEED to?]
    Edit "Subject:" lines, especially if you're taking a tangent.
    Send mail instead, avoid posting follow ups. (1 mail message worth
	100 posts).
    Internet mail readers: send requests to add/drop to SPACE-REQUEST
	not SPACE.
    Read all available articles before posting a follow-up. (Check all
	references.)
    Cut down attributed articles (leave only the points you're
	responding to; remove signatures and headers). Summarize!
    Put a return address in the body (signature) of your message (mail
	or article), state your institution, etc. Don't assume the
	'reply' function of mailers will work.
    Use absolute dates. Post in a timely way. Don't post what everyone
	will get on TV anyway.
    Some editors and window systems do character count line wrapping:
	keep lines under 80 characters for those using ASCII terminals
	(use carriage returns).


    INDEX TO LINKED POSTINGS

    I've attempted to break the postings up into related areas. There isn't
    a keyword index yet; the following lists the major subject areas in each

    CREDITS

    Eugene Miya started a series of linked FAQ postings some years ago which
    inspired (and was largely absorbed into) this set.

    Peter Yee and Ron Baalke have and continue to spend a lot of their own
    time setting up the SPACE archives at NASA Ames and forwarding official
    NASA announcements.

    Many other people have contributed material to this list in the form of
    old postings to sci.space and sci.astro which I've edited. Please let me
    know if corrections need to be made. Contributors I've managed to keep
