SPACE/NET - Network Resources

NETWORK RESOURCES

OVERVIEW

You may be reading this document on many types of computers, so much of
the material below may not apply to you. In general, however, systems
connected to 'the net' fall in one of three categories: Internet,
Usenet, or BITNET. Electronic mail may be sent between these networks,
and other resources available on one of these networks are sometimes
accessible from other networks by email sent to special 'servers'.

The space and astronomy discussion groups actually are composed of
several mechanisms with (mostly) transparent connections between them.

One mechanism is the mailing list, in which mail is sent to a central
distribution point which relays it to all recipients of the list. In
addition to the general lists for space (called SPACE Digest for
Internet users, and SPACE on BITNET), there are a number of more
specialized mailing lists described below.

A second mechanism is Usenet 'netnews'. This is somewhat like a bulletin
board operating on each system which is a part of the net. Netnews
separates contributions into hundreds of different categories based on a
'group name'. The groups dealing most closely with space topics are
called:

sci.astro - astronomy
sci.astro.* - various topic-specific subgroups
alt.sci.planetary - planetary science. sci.space.science is
probably a better group for most purposes.
talk.politics.space - space politics. sci.space.policy is
preferred.
sci.space.news - moderated, for mission status reports,
news announcements, etc.
sci.space - general space discussion. To be removed soon, replaced
by:

sci.space.tech - moderated, technical/hardware issues
sci.space.science - moderated, space & planetary science
sci.space.policy - unmoderated, space policy

Contributors 'post' submissions (called 'articles' in netnews
terminology) on their local machine, which sends it to other nearby
machines. Similarly, articles sent from nearby machines are stored
locally and may be forwarded to other systems, so that an article is
posted locally and eventually reaches all the Usenet sites interested in
receiving the news group to which the article was posted.

Gateway machines redirect several of the Usenet sci.space groups into
Internet and BITNET mailing lists and vice versa; the other Usenet
groups are not accessible as mailing lists. If you can receive netnews,
its more flexible interface and access to a wider range of material
usually make it the preferred option.

MAILING LISTS

SPACE Digest is the main Internet list, and is now being run by the
International Space University (in only its second change of management
in over a decade). Email space-request@isu.isunet.edu (message body
should be in the format 'subscribe space John Public') to join. Note
that the moderated SPACE Magazine list is defunct at present for lack of
a moderator. Old copies of SPACE Digest since its inception in 1981 are
in

ftp://julius.cs.qub.ac.uk/pub/SpaceDigestArchive/

Elements is a moderated list for fast distribution of Space Shuttle
Keplerian Elements before and during Shuttle flights. NASA two line
elements are sent out on the list from Dr. Kelso, JSC, and other sources
as they are released. Email to elements-request@telesoft.com to join.

GPS Digest is a moderated list for discussion of the Global Positioning
System and other satellite navigation positioning systems. Email to
gps-request@esseye.si.com to join.

Space-investors is a list for information relevant to investing in
space-related companies. Email Vincent Cate (vac@cs.cmu.edu) to join.

Space-tech is a list for more technical discussion of space topics;
discussion has included esoteric propulsion technologies, asteroid
capture, starflight, orbital debris removal, etc. Email to
space-tech-request@cs.cmu.edu to join. Archives of old digests and
selected excerpts are in

ftp://b.gp.cs.cmu.edu/usr/mnt/public/space-tech/

or by email to space-tech-request if you don't have FTP access.

Ssi-mail is a discussion group covering the Space Studies Institute.
Email to listserv@link.com with a message saying "subscribe ssi_mail
First Name Last Name".

SEDS-L is a BITNET list for members of Students for the Exploration and
Development of Space and other interested parties. Email
LISTSERV@TAMVM1.BITNET with a message saying "SUBSCRIBE SEDS-L your
name". Email saying "INDEX SEDS-L" to list the archive contents.

SEDSNEWS is a BITNET list for news items, press releases, shuttle status
reports, and the like. This duplicates material which is also found in
Space Digest, sci.space.news, sci.space.shuttle, and sci.astro. Email
LISTSERV@TAMVM1.BITNET saying "SUBSCRIBE SEDSNEWS your name" to join.
Email saying "INDEX SEDSNEWS" to list the archive contents.

Ron Baalke (baalke@kelvin.jpl.nasa.gov) runs a mailing list which
carries the contents of the sci.space.news Usenet group. Email him to
join the list.

As a general note, please mail to the *request* address to get off a
mailing list. SPACE Digest, for example, relays many inappropriate
'please remove me from this list' messages which are sent to the list
address rather than the request address.

PERIODICALLY UPDATED INFORMATION

In addition to this FAQ list, a broad variety of topical information is
posted to the net (unless otherwise noted, in the group sci.space.news
created for this purpose). Please remember that the individuals posting
this information are performing a service for all net readers, and don't
take up their time with frivolous requests.

ASTRO-FTP LIST
Veikko Makela (veikko.makela@helsinki.fi) posts a monthly list of
anonymous FTP servers containing astronomy and space related
material to sci.space and sci.astro.

AVIATION WEEK
Henry Spencer (henry@zoo.toronto.edu) posts summaries of
space-related stories in the weekly _Aviation Week and Space
Technology_.

The EJASA Volume Lists for ordering back issues may be requested
from him, and back issues are also available from the ASA site

ftp://chara.gsu.edu/

FLIGHT INTERNATIONAL
Swaraj Jeyasingh (sjeyasin@axion.bt.co.uk) posts summaries of
space-related news from _Flight International_. This focuses more on
non-US space activities than Aviation Week.

IAU CIRCULARS
The IAUC are copyrighted, and should normally not be posted to the
net (sometimes they are posted, with Brian Marsden's permission).
The best way to get all the IAUC is to subscribe: you get all the
info by e-mail, and it helps the Minor Planet Center.

A subscription is $7.50 per month for hardcopy or e-mail delivery
(e-mail version includes log-in privileges to collect the Circulars,
as well as orbits from the MPC files, and a facility for computing
ephemerides).

Enquiries (and checks) should be sent to

Central Bureau for Astronomical Telegrams
Smithsonian Astrophysical Observatory
Cambridge, MA 02138, U.S.A.
Email: marsden@cfa.harvard.edu

with checks (in U.S. dollars) made out to "Central Bureau for
Astronomical Telegrams". Subscribers can also purchase the MPC's
cometary orbit catalogue at half price. A more complete description
of IAUC/MPC services is available from the email contact.

LARGE ASTRONOMICAL PROJECTS
Robert Bunge (rbunge@access.digex.com) posts a list describing many
"Large Telescope Projects Either Being Considered or in the Works"
to sci.astro.
