- 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.

- 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

-
- 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

- 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:
