-
-
- INTRODUCTION
-
- A wide variety of images, data, catalogs, information releases, and
- other material dealing with space and astronomy may be found on the net.
- The sources with the broadest selection of material are the NASA Ames
- SPACE archive and the National Space Science Data Center (described
- below).
-
- A few sites offer direct dialup access or remote login access, while
- others offer file transfer over the Internet (referred to as 'anonymous
- FTP'). Sites not connected to the Internet cannot use FTP directly, but
- there are a few automated FTP servers which operate via email. Send mail
- containing only the word HELP to ftpmail@decwrl.dec.com,
- bitftp@pucc.princeton.edu, or ftpmail@doc.ic.ac.uk, and the servers will
- send you instructions on how to make requests.
-
- Shorthand for a specific file or directory at an anonymous FTP site is
-
- ftp://sitename/pathname[/]
-
- (e.g. ftp://explorer.arc.nasa.gov/pub/SPACE/Index). The format has been
- changed to valid URLs for users of the World Wide Web. If you are using
- a normal FTP client, you will connect to the sitename part of the URL
- (explorer.arc.nasa.gov, in this case) and get the file specified by the
- pathname (/pub/SPACE/Index). If a '/' terminates the URL, it indicates a
- directory containing multiple files.
-
-
- WORLD WIDE WEB (WWW)
-
- WWW is a global hypermedia network carried on the Internet and
- incorporating popular protocols including FTP, WAIS, gopher, archie,
- NNTP (netnews), etc. The Web is growing at an explosive pace, and huge
- amounts of space-related information are already online. The FAQ no
- contains many URLs (Universal Resource Locators) specifying files
- available by FTP (discussed above), sites accessible by telnet (URLs of
- the form telnet://sitename), and Web hypertext documents
- (http://site/page).
-
- If you are not familiar with the Web, you should probably begin by
- obtaining a Web browser (typically NCSA Mosaic for X, Mac, and PC) and
- exploring. The newsgroup 'comp.infosystems.www.announce' is also
- available.
-
- The NASA Web home page is at
-
- http://www.gsfc.nasa.gov/NASA_homepage.html
-
- Other space-related material may be found on the Web starting with the
- overview page at
-
- http://info.cern.ch/Space/Overview.html
-
- There is also a pointer in the "information by subject" page under
- "Space Science."
-
-
- VIEWING IMAGES
-
- Don't ask for images to be posted to the space/astro newsgroups. They're
- clumsy to access, wasteful of net resources, and inappropriate in
- discussion groups. Retrieve images on your own using FTP or Web clients.
-
- The possible combinations of image formats and machines is forebodingly
- large, and I won't attempt to cover common formats (GIF, etc.) here. To
- read PDS and VICAR (and many other) formats on Unix systems running X,
- use XV 3.00, available in
-
- ftp://ftp.x.org/contrib/xv-3.00.tar.Z
-
- The FAQ for the Usenet group alt.binaries.pictures discusses image
- formats and how to get image viewing software. A copy of this document
- is available from the Usenet FAQ archives in
-
- ftp://rtfm.mit.edu/pub/usenet/alt.binaries.pictures

- COMETARY / MINOR PLANET ORBITAL DATA
-
- Catalogue of Cometary Orbits
-
- The availability of the tenth edition of the Catalogue of Cometary
- Orbits was announced on IAUC 6128 issued on 1995 Jan. 27. The 108 pages
- contain 1472 sets of orbital elements (in the J2000.0 system) for 1444
- cometary apparitions through the end of 1994. The latest edition is the
- first to utilise the new cometary designations and includes detailed
- cross-references with the pre-1995 scheme. As an entirely new feature,
- there is a special tabulation giving osculating elements for the 116
- numbered periodic comets (excluding five deemed to be lost) for the
- epochs 1995 Mar. 24 and Oct. 10. The price, postage included is US$20.00
- (US$30.00 by airmail outside North America). The main part of the
- catalogue and the table of `original' and `future' 1/a values for the
- 298 long-period comets of the highest quality can by supplied by e-mail
- for US$50.00; they are also available on an MS-DOS diskette (5.25-inch

- Catalogue Of Orbits Of Unnumbered Minor Planets
-
- The availability of the fifth edition of this catalogue was announced on
- Minor Planet Circular (MPC) 24251. It contains orbital elements for
- 15587 single-opposition minor planets, all without consideration of
- perturbations, and is complete through the 1994 Nov. 18 batch of MPCs.
- The 4553 unnumbered multiple-opposition and long-arc perturbed orbits
- are in the Catalogue of High-Precision Orbits of Unnumbered Minor
- Planets. The catalogue is available for $30.00 ($40.00 for airmail
- delivery), and the orbits are also being issued on an MS-DOS diskette
- for $120.00.

- Catalogue Of High-Precision Orbits Of Unnumbered Minor Planets
-
- The 1995 (third) edition of this annual publication was announced on
- Minor Planet Circular (MPC) 24133. The orbits given are for the epoch
- 1995 Oct. 10.0 TT and the catalogue is complete through th 1994 Nov. 18
- batch of MPCs. Osculating elements for the epoch 1995 Oct. 10.0 TT = JDT
- 2450000.5 are given for 4750 multiple-opposition and 227 long-arc
- perturbed orbits. Opposition positions and motions are given for objects
- that reach opposition between 1994 Dec. 1 and 1996 Jan. 31; more
- extensive ephemerides are given for unusual minor planets. The new
- catalogue, intended as a companion to the Efemeridy Malykh Planet (EMP),
- costs $30.00 ($40.00 for airmail delivery). The orbits are also being
- issued on an MS-DOS diskette for $120.00; the ephemerides are not
- included, but there is a PC-computer program for generating them.
-
- If both the Catalogue of High-Precision Orbits of Unnumbered Minor
- Planets and the Catalogue Of Orbits Of Unnumbered Minor Planets are
- desired, they are available at the special price of $50.00 ($65.00 for
- airmail delivery). The corresponding MS-DOS diskettes are available for
- $200.00 the pair.

- Minor Planet Circulars
-
- The Minor Planet Circulars (MPCs) (also known as Minor Planets and
- Comets) are published generally on the date of each full moon. The
- Circulars contain astrometric observations, orbits and ephemerides of
- both minor planets and comets. New numberings and namings of minor
- planets, as well as numberings of periodic comets, are announced in the
- Circulars. An average batch of MPCs runs to over 150 two-column pages
- and contains over 7000 minor-planet observations. Details from the Minor
- Planet Center (address above). Sample pages are displayed at
