ONLINE AND OTHER SOURCES OF IMAGES, DATA, ETC.


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/FAQ/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/FAQ/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. This FAQ is
    evolving towards a fully hyperlinked Web document (a plain text version
    will continue to be posted to the net, of course). The primary change at
    present is the use of Web URLs (Universal Resource Locators) to specify
    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' is also available.

    The NASA Web home page is at

	http://hypatia.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


ONLINE ARCHIVES

    DEFENSE METEOROLOGICAL SATELLITE PROGRAM (DMSP)

    DMSP is a two satellite constellation of near-polar orbiting, sun
    synchronous satellites monitoring meteorological, oceanographic and
    solar-terrestrial physics environments. DMSP sample data and information
    may be accessed on-line via:

	ftp://ftp.ngdc.noaa.gov/DMSP/
	http://web.ngdc.noaa.gov/dmsp/dmsp.html

    Contact Greg Deuel (dmsp@mail.ngdc.noaa.gov).


    INFRARED PROCESSING & ANALYSIS CENTER

    Caltech's IPAC provides access to an easy-to-use interface for making
    queries of many astronomical catalogs, especially those from the
    Infrared Astronomical Satellite (IRAS) mission. You can also query the
    Bright Star catalog, SAO star catalog, a number of extragalactic
    (galaxy/quasar) catalogs, etc. Results can be saved to flat ASCII tables
    or FITS files and copied to your computer via FTP. Using the interface
    requires a machine running X Windows. You can get to IPAC via

	http://xcatscan.ipac.caltech.edu
	telnet://xcatscan.ipac.caltech.edu

    Log in as "xcatscan" (no password needed).

    NASA AMES

    Extensive archives are maintained at NASA Ames and are available via
    anonymous FTP or an email server. These archives include many images and
    a wide variety of documents including this FAQ list, NASA press
    releases, shuttle launch advisories, and mission status reports. Please
    note that these are NOT maintained on an official basis.

    A listing of files available in the archive is in

	ftp://explorer.arc.nasa.gov/pub/SPACE/Index

    An email server for the SPACE archive is temporarily out of service due
    to the archive moving to its new home, explorer. Instructions for
    accessing the email server will be returned to the FAQ when the server
    is running again.

    Magellan, Voyager, and Viking CD-ROMs are online in

	ftp://explorer.arc.nasa.gov/cdrom/

    Tens of thousands of images are available.

    The GIF directory contains images in GIF format. The VICAR directory
    contains Magellan images in VICAR format (these are also available in
    the GIF directory). A PC program capable of displaying these files is
    found in the IMDISP directory (see the item "VIEWING IMAGES" below).

    The NASA media guide describes the various NASA centers and how to
    contact their public affairs officers; this may be useful when pursuing
    specific information. It's in

	ftp://explorer.arc.nasa.gov/pub/SPACE/MISC/media.guide

    Contact Peter Yee (yee@ames.arc.nasa.gov).

    NASA SPACELINK

    SpaceLink is an online service located at Marshall Space Flight Center
    in Huntsville, Alabama. The system is specifically designed for
    teachers. The data base is arranged to provide easy access to current
    and historical information on NASA aeronautics, space research, and
    technology transfer information. Also included are suggested classroom
    activities that incorporate information on NASA projects to teach a
    number of scientific principles. Unlike bulletin board systems, NASA
    Spacelink does not provide for interaction between callers. However it
    does allow teachers and other callers to leave questions and comments
    for NASA which may be answered by regular mail. Messages are answered
    electronically, even to acknowledge requests which will be fulfilled by
    mail. Messages are generally handled the next working day except during
    missions when turnaround times increase. The mail system is closed-loop
    between the user and NASA.

    SpaceLink also offers downloadable shareware and public domain programs
    useful for science educators as well as space graphics and GIF images
    from NASA's planetary probes and the Hubble Telescope.

    You can access SpaceLink via

	telnet://spacelink.msfc.nasa.gov
	ftp://spacelink.msfc.nasa.gov

    Friedrichsen (terry@venus.sunquest.com).

    The "Variable Stars Analysis Software Archive" is in

	ftp://kauri.vuw.ac.nz/pub/astrophys/

    This is intended for specialists in this field, and they would
    appreciate people from outside New Zealand confining their FTP access to
    the astrophys directory, as they pay a significant amount for Internet
    access. Contributions are encouraged. Contact the archive administrator,
    Timothy Banks (bankst@kauri.vuw.ac.nz).

    The "IDL Astronomy Users Library" is in

	ftp://idlastro.gsfc.nasa.gov/README

    This is a central repository for general purpose astronomy procedures
    written in IDL, a commercial image processing, plotting, and programming
    language. Contact Wayne Landsman (landsman@stars.gsfc.nasa.gov).


    ORBITAL ELEMENT SETS

    The most recent orbital elements from the NASA Prediction Bulletins are
    carried on the Celestial BBS, (513)-427-0674. Documentation and tracking
    software are also available on this system. The Celestial BBS may be
    accessed 24 hours/day at 300, 1200, or 2400 baud using 8 data bits, 1
    stop bit, no parity.

    Orbital element sets are FTPable from the following directories:

    SPACE DIGEST ARCHIVES

    Copies of back issues of Space Digest are archived on
    LISTSERV@UGA.BITNET. Send mail containing the message "INDEX SPACE" to
    get an index of files; send it the message "GET filename filetype" to
    get a particular file.


LANDSAT AND NASA PHOTOS

    You can get black-and-white 1:1M prints, negatives, or positives for
    $10, $18, $12 respectively for any Landsat data more than 2 years old
    from EDC, (Eros (Earth Resources Orbiting Satellite) Data Center). Call
    them at (605)-594-6511. You get 80 meter resolution from the MSS
    scanner, 135x180 kilometers on a picture 135x180 mm in size. I think you
    have to select one band from (green, red, near IR, second near IR), but
    I'm not sure. Digitial data is also available at higher prices.

    Transparencies of all NASA photos available to the public can be
    borrowed from the NASA photo archive; you can have copies or prints
    made.

PLANETARY MAPS

    The following list gives brief references to maps of all bodies other
    than Earth for which maps have been drawn - 45 by Nov. 1993. The list
    will be updated periodically. Where many maps exist for a world (e.g.
    Mars) a good general purpose global map is listed. Where appropriate
    these are subdivided further: relief maps (usually with feature names),
    topography (contours), geological maps etc. Otherwise (e.g. Deimos) the
    best available map is listed. Some (e.g. Comet Encke) are very simple
    diagrams of possible surface features ('sketch' under map type). A few
    interesting atlases are listed at the end of the main table. Users
    noting errors or omissions are urged to contact Phil Stooke at
    stooke@vaxr.sscl.uwo.ca.

    References: USGS refers to the U.S. Geological Survey. Order maps by I-
    number from USGS Map Sales, Box 25286, Denver, Colorado USA 80225. Most
    maps cost about $3 per sheet (some listed maps are sets of several
    sheets), but check cost with USGS before ordering. NASA Tech. Memo.
    4395, 'Indexes of Maps of the Planets and Satellites 1992' by J.L. Inge
    and R.M. Batson, is an excellent guide to sheet maps (but not the
    journal illustrations). Apollo-era Moon maps (LAC, LTO) are mostly out
    of print, but some may still be available from NSSDC (as are NASA
    CD-ROMs): National Space Science Data Center, Goddard Space Flight
    Center, Greenbelt, Maryland USA 20771. Other references are to books and
    journals. Although not full bibliographic entries, to save space, there
    should be enough information to enable the item to be found.

    I will answer questions about planetary maps by e-mail at:
    stooke@vaxr.sscl.uwo.ca (Phil Stooke)

COMETARY ORBIT DATA

    The Central Bureau for Astronomical Telegrams and the Minor Planet
    Center announce the sixth edition of the Catalogue of Cometary Orbits in
    IAU Circular 4935. The catalogue contains 1292 entries which represent
    all known comets through November 1989 and is 96 pages long.
    Non-subscribers to the Circulars may purchase the catalogue for $15.00
    while the cost to subscribers is $7.50. The basic catalogue in ASCII
    along with a program to extract specific orbits and calculate
    ephemerides is available on MS-DOS 5.25-inch 2S2D diskette at a cost of
    $75.00 (the program requires an 8087 math coprocessor). The catalogue
    alone is also available by e-mail for $37.50 or on magnetic tape for
    $300.00.

    Except for the printed version of the catalogue, the various magnetic
    media or e-mail forms of the catalogue do not specifically meantion
    non-subscribers. It is possible that these forms of the catalogue may
    not be available to non-subscribers or that their prices may be more
    expensive than those given. Mail requests for specific information and
    orders to:
