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 the
remainder support some form of file transfer. Many sites are listed as
providing 'anonymous FTP' (or files referred to as 'FTPable'). This
refers to the File Transfer Protocol on the Internet. 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 or bitftp@pucc.princeton.edu,
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
sitename:filename (e.g. ames.arc.nasa.gov:pub/SPACE/FAQ/Index). The FAQ
is phasing out the specification of IP addresses and referring to FTP
sites only by fully qualified machine name.
An ever-increasing amount of space-related data may be searched and
retrieved interactively using gopher, WAIS, World Wide Web, and other
Internet clients that may be far more convenient than FTP. A description
of these applications is beyond the scope of this FAQ; see the Usenet
groups comp.infosystems.{gopher,wais,www} for more information.
Don't even ask for images to be posted to the net. The data volume is
huge and nobody wants to spend the time on it.
VIEWING IMAGES
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 by anonymous FTP from
export.lcs.mit.edu:contrib/xv-3.00.tar.Z, as well as the other standard
X11 FTP sites.
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
rtfm.mit.edu:pub/usenet/alt.binaries.pictures.
ONLINE ARCHIVES
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 FTPable from
ames.arc.nasa.gov:pub/SPACE/Index.
To access the archives by email, send a letter to
archive-server@ames.arc.nasa.gov (or ames!archive-server). In the
subject of your letter (or in the body), use commands like:
send SPACE Index
send SPACE SHUTTLE/ss01.23.91.
The capitalization of the subdirectory names is important. All are in
caps. Only text files are handled by the email server at present; use
one of the FTP email servers described in the introduction to this
section for images or programs.
The Magellan Venus and Voyager Jupiter, Saturn, and Uranus CD-ROM image
disks have been put online in the CDROM and CDROM2 directories. The
disks will be rotated on a weekly basis. Thousands of images are
available in these collections.
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 MISC/media.guide.
Any problems with the archive server should be reported to Peter Yee
(yee@ames.arc.nasa.gov).
NASA ASTROPHYSICS DATA SYSTEM
The ADS is a distributed data retrieval system which is easy to use and
provides uniform access to ground-based and space-based astronomy data
from NASA data centers across the country. It currently has over 140
data catalogs of radio, infrared, optical, UV, and X-ray data which can
be queried by position or any other parameter in the catalog. The ADS
also provides tools to manipulate and plot tabular results. In addition,
ADS has a Beta version of an Abstracts Service which allows users to
query over 125,000 abstracts of astronomy papers since 1975 by authors,
keywords, title words, or abstract text words.
ADS use requires direct Internet access. For more info and to sign up to
become a user, email ads@cuads.coloradu.edu. The User's Guide and
"QuickStart" Guide (PostScript files) are FTPable from directory
sao-ftp.harvard.edu:pub/ads/ADS_User_Guide.
Contact Carolyn Stern Grant (stern@cfa.harvard.edu).

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 dial in at (205)-895-0028 (300/1200/2400/9600(V.32) baud, 8
bits, no parity, 1 stop bit), or telnet to spacelink.msfc.nasa.gov
(128.158.13.250, also known as xsl.msfc.nasa.gov) if you're on the
Internet. Anonymous FTP capability (password guest) is now available.
Most of this information is also available from the Ames server in
directory SPACELINK.
NATIONAL SPACE SCIENCE DATA CENTER (NSSDC)
The National Space Science Data Center is the official clearinghouse for
NASA data. The data catalog (*not* the data itself) is available online.
Internet users can telnet to nssdca.gsfc.nasa.gov (128.183.36.23) and
log in as 'NODIS' (no password). You can also get the catalog by sending
email to 'request@nssdc.gsfc.nasa.gov'.
You can also dial in at (301)-286-9000 (300, 1200, or 2400 baud, 8 bits,
no parity, one stop). At the "Enter Number:" prompt, enter MD and
carriage return. When the system responds "Call Complete," enter a few
more carriage returns to get the "Username:" and log in as 'NODIS' (no
password).
The system is menu-driven; topics available as of 3/93 are:
1 - Master Directory - NASA & Global Change
2 - Personnel Information Management System
3 - Nimbus-7 GRID TOMS Data
4 - Interplanetary Medium Data (OMNI)
5 - Request data and/or information from NSSDC

For users with Internet access, datasets are made available via
anonymous FTP once you select the desired datasets from the online
catalog. For other users, data may be ordered on CD-ROM and in other
formats. Among the many types of data available are Voyager, Magellan,
and other planetary images, Earth observation data, and star catalogs.
Viewers for Macintosh and IBM systems are also available. As an example
of the cost, an 8 CD set of Voyager images is $75. Data may ordered
online, by email, or by physical mail. The postal address is:

SPACE TELESCOPE SCIENCE INSTITUTE ELECTRONIC INFORMATION SERVICE
STEIS contains a large amount of information about the Hubble Space
Telescope, such as status reports and newsletters, in addition to
material oriented towards HST observers and proposers. FTP
stsci.edu:README to begin with. Contact Pete Reppert (reppert@stsci.edu)
or Chris O'Dea (odea@stsci.edu).
STARCAT
The Space Telescope European Coordination Facility, at ESO/Garching
provides on-line access to a huge astronomical database, featuring
- Observation log files of several satellites/telescopes
(IUE,IRAS,HST,NTT...).
- Spectra and images (IUE, HST).
- Most of the astronomical catalogues (SAO, HR, NGC, PPM, IRAS,
Veron, GSC and many others, more than 50) in a very convenient
way (give center+radius+kind of objects, and you get the
corresponding files!).
Log on as ``starcat'' (no password) on node stesis.hq.eso.org
(134.171.8.100) or on STESIS (DECnet). The files created can be
retreived by FTP. Contact: Benoit Pirenne, bpirenne@eso.org (phone +49
89 320 06 433) at ST-ECF
ASTRONOMICAL DATABASES
The full SAO stellar database is *NOT* available online, probably due to
the 40 MB size. It may be ordered on magnetic tape from the NSSDC. A
subset containing position and magnitude only is available by FTP (see
"Astronomy Programs" below).
nic.funet.fi:pub/astro contains a large collection of astronomical
programs for many types of computers, databases of stars and deep sky
objects, and general astronomy information. This site is mainly for
European users, but overseas connections are possible.
ames.arc.nasa.gov:pub/SPACE/MISC/galaxy.dat is a database of 8,436
galaxies including name, RA, declination, magnitude, and radial
velocity, supplied by Wayne Hayes (wayne@csri.utoronto.ca).
ames.arc.nasa.gov:pub/SPACE/FAQ/constell.* contains constellation
boundary data in a form suitable for the construction of star charts and
atlases.
Directory iris1.ucis.dal.ca:pub/gif has a number of GIFs from Voyager,
Hubble, and other sources (most of this data is also in pub/SPACE/GIF on
the Ames server). Please restrict access to 5pm - 8am Atlantic time.
Directory pomona.claremont.edu:[.YALE_BSC] contains the the Yale Bright
Star catalog. Contact James Dishaw (jdishaw@hmcvax.claremont.edu).

Xephem is an interactive astronomical ephemeris program for X11R4/Motif
1.1 (or later) X Windows systems. It computes lots of information about
the planets and any solar system objects for which orbital elements are
available. A sample database of some 16000+ objects is included in the
release kit. It's available by anonymous FTP from
export.lcs.mit.edu:contrib/xephem/xephem_2.4e.tar.Z and has been
submitted to comp.sources.x. Contact Elwood Downey
(e_downey@tasha.cca.cr.rockwell.com). Ephem is the forefather of xephem
designed for simple 24x80 character displays. It's FTPable from
export.lcs.mit.edu:contrib/ephem_4.28.tar.Z.
XSAT, an X Window System based satellite tracking program, is available
from export.lcs.mit.edu:contrib/xsat1.0.tar.Z. Contact Dave Curry
(davy@ecn.purdue.edu) for more information.
Xsky 2.0.1, a computerized sky atlas for the X Window System, is
available from arizona.edu:[.software.unix.xsky]xsky2-0-1.tarz. Contact
Terry R. Friedrichsen (terry@venus.sunquest.com) for more information.
The "Variable Stars Analysis Software Archive" is available in directory
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. Contents are relatively sparse
at present due to the youth of the archive - contributions are
encouraged. Contact the archive administrator, Timothy Banks
(bankst@kauri.vuw.ac.nz) for more information.
The "IDL Astronomy Users Library" is FTPable from
idlastro.gsfc.nasa.gov:README (to start with). 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) for more information.
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:
archive.afit.af.mil:pub/space NASA,TVRO,Shuttle
ftp.funet.fi:pub/astro/pc/satel NASA,TVRO,Molczan,CelBBS,Shuttle
kilroy.jpl.nasa.gov:pub/space NASA,Molczan
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 - 43 by July 1993. The list
will be updated periodically. Where many maps exist for a world (e.g.
Mars) the best (or a typical) general purpose global map is listed,
subdivided into relief maps (usually with feature names), topography
(contours) and geol- ogical maps. Otherwise (e.g. Deimos) the best
available map is listed. Some (e.g. Comet Encke) are merely simple
diagrams of possible surface features ('sketch' under map type). Users
noting errors or omissions are urged to contact Phil Stooke at the
address below.
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
sheets cost about $3 each (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 (i.e. not journal
illustrations). Apollo-era Moon maps (LAC, LTO) are mostly out of print,
but may still be available from NSSDC (plus 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:
