Archive-name: space/net Last-modified: $Date: 93/07/03 15:33:16 $ NETWORK RESOURCES OVERVIEW You may be reading this document on any one of an amazing variety 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.space.news', 'sci.space', 'sci.space.shuttle', 'sci.astro', and 'talk.politics.space'. 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 the Usenet sci.space group 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 firstname.lastname@example.org (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 FTPable from directory julius.cs.qub.ac.uk:pub/SpaceDigestArchive (get README to begin with). 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 email@example.com to join. GPS Digest is a moderated list for discussion of the Global Positioning System and other satellite navigation positioning systems. Email to firstname.lastname@example.org to join. Space-investors is a list for information relevant to investing in space-related companies. Email Vincent Cate (email@example.com) 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 firstname.lastname@example.org to join. Archives of old digests and selected excerpts are FTPable from directory gs80.sp.cs.cmu.edu:/usr/anon/public/space-tech, or by email to space-tech-request if you don't have FTP access. 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, 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 (email@example.com) 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 new 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. ACRONYMS Garrett Wollman (wollman@UVM.EDU) posts an acronym list around the first of each month.
