I sympathize with what you're trying to say. However, I would like to point
out that you've been mislead about Einstein. In fact, it's quite remarkable
how quickly the special and general theories of relativity were accepted.
The original paper on relativity was published in 1905.
By 1909, several other prominent researchers (including Hilbert
and Minkowski) were working on it, and in the same year Einstein was
awarded an honorary doctorate from the University of Geneva, and gave an
invited paper at a conference in Salzburg. He was also appointed to a
position at the University of Zurich. He was hardly being "looked down
upon". [Source: "Einstein: The Life and Times", Ronald W. Clark]

(I think physicists in general have displayed a remarkable willingness
to quickly accept radical new theories, such as quantum mechanics
and relativity, that seem to be full of crazy ideas, *as long as there
is good reason to*. Alas, there seems to be no good evidence for
"reactionless drives", and moreover many good reasons to suspect that
such things are impossible.)

Subject: Galileo Update - 06/20/91

Crossposted by Ron Baalke from the NASAMAIL P bulletin board
(All NASAMAIL board P items are O.K. for unlimited distribution per JPL PIO,
unless the postings indicate otherwise)

                     GALILEO MISSION STATUS
                          June 20, 1991

     The Galileo spacecraft is almost 82 million miles from
Earth, receding at about 1 million miles each day.  Its distance
from the Sun is 162 million miles.  Speed in orbit is 48,347 mph;
round-trip communication time is nearly 15 minutes.

     The spacecraft health and performance continue to be
excellent, except for the partly deployed high-gain antenna.
Galileo's engineering telemetry data rate has been reduced to 10
bits per second (through the low-gain antenna) to permit
communication with the 34-meter ground stations.  The spacecraft
is in the dual-spin mode, with the upper part spinning at about
3.15 revolutions per minute and the lower part not spinning.

     Meanwhile back on Earth, the Galileo flight team has been
very busy designing and reviewing the next trajectory correction
maneuver planned for July 2, the next cruise sequence or computer
program to control spacecraft operations starting in September,
and the Gaspra asteroid encounter, scheduled for October 29.  The
team continues intensive analysis and testing aimed ultimately at
deploying the high-gain antenna.

Subject: Strange lights in the sky...


I was looking due south out of my apartment here in Iowa City, and noticed
a series of 'cloud bursts', which started at about 2h0m UT.  It looks like
they are about at 15h18m, -2deg15m.  They are pretty bright, white/gray in
color, and emit from a constant position.  They expand/disperse in ~2min,
with new clouds starting ~4 min.  We have a pretty heavy cloud cover right
now, so I really don't think that these things are atmospheric tests,
but just on a whim, are there any satellite chemical releases going on at
the moment?

Thanks,
Paul
