They recycled a lot of models and theme music for UFO. Some of the
concepts even showed up in SPACE: 1999.
Software engineering? That's like military intelligence, isn't it?
Todays New York TImes just wrote about a pact being negotiated
between us and the Russians to develope High Temperature
Gas Cooled Fission Reactors using Re-Cycled Weapons Grade plutonium
from Warhead stockpiles. THe fuel will be pelletized in ceramic
for safety, and then after depletion will be sufficiently
contaminated with by-products to make extraction of the remaining
plutonium hazardous enough to deter re-use.
Apparently the project will be led by General Atomics of San Diego
with funding from the US GOvernment. THe pilot plant will be built
and operated by the russians.

The sightings were apparently spurious. There is no planet inside of
the orbit of Mercury.
The idea of Vulcan came from the differences between Mercury's observed
perihelion precession and the value it should have had according to
Newtonian physics. Leverrier made an extensive set of observations
and calculations during the mid 19th century, and Simon Newcombe later
improved on the observations and re-calculated using Leverrier's system
of equations. Now Leverrier was one of the co-discoverers of Neptune
and since he had predicted its existence based on anomalies in the orbit
of Uranus his inclination was to believe the same sort of thing was
afoot with Mercury.
But alas, 'twere not so. Mercury's perihelion precesses at the rate
it does because the space where it resides near the sun is significantly
curved due to the sun's mass. This explanation had to wait until 1915
and Albert Einstein's synthesis of his earlier theory of the electrodynamics
of moving bodies (commonly called Special Relativity) with Reimanian
geometry. The result was the General Theory of Relativity, and one of
it's most noteworthy strengths is that it accounts for the precession
of Mercury's perihelion almost exactly. (Exactly if you use Newcomb's
numbers rather than Leverrier's.)
Of course not everybody believes Einstein, and that's fine. But subsequent
efforts to find any planets closer to the sun than Mercury using radar
have been fruitless.

A wide variety of images, data, catalogs, information releases, and
other material dealing with space and astronomy may be found on the net.
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'. 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 operates via
email. Send mail containing only the word HELP to [email protected]
or [email protected], and the servers will send you instructions
on how to make requests.
The sources with the broadest selection of material are the NASA Ames
SPACE archive and the National Space Science Data Center.
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.
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 2.11, available by anonymous FTP from export.lcs.mit.edu
(18.24.0.12) in contrib/xv-2.11.tar.Z and 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 by anonymous FTP from the Usenet FAQ archives at
pit-manager.mit.edu (18.72.1.58), in directory
pub/usenet/alt.binaries.pictures.
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.
FTP users should connect to ames.arc.nasa.gov (128.102.18.3) and look in
pub/SPACE. pub/SPACE/Index contains a listing of files available in the
archive (the index is about 200K by itself).
To access the archives by email, send a letter to
[email protected] (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).
