I know this may sound like a weird kind of question, but we were discussing
a comment in an SciFi book about the effect of zero-gravity on a female
characters breasts, and started wondering what really happens to womens
breasts in space. Do women astronauts need to wear bras, for example?

The technology described in the article copied below could be used to
power spacecraft, space colonies, etc.:
FREE-ENERGY TECHNOLOGY
by Robert E. McElwaine, Physicist
Ninety to a hundred years ago, everybody "knew" that a
heavier-than-air machine could not possibly fly. It would
violate the "laws" of physics. All of the "experts" and
"authorities" said so.
For example, Simon Newcomb declared in 1901: "The
demonstration that no possible combination of known
substances, known forms of machinery and known forms of
force, can be united in a practical machine by which man
shall fly long distances through the air, seems to the writer
as complete as it is possible for the demonstration of any
physical fact to be."
Fortunately, a few SMART people such as the Wright
Brothers did NOT accept such pronouncements as the final
word. Now we take airplanes for granted, (except when they
crash).
Today, orthodox physicists and other "scientists" are
saying similar things against several kinds of 'Free Energy'
Technologies, using negative terms such as "pseudo-science"
and "perpetual motion", and citing so-called "laws" which
assert that "energy cannot be created or destroyed" ("1st law
of thermodynamics") and "there is always a decrease in useful
energy" ("2nd law of thermodynamics"). The physicists do not
know how to do certain things, so they ARROGANTLY declare
that those things cannot be done. Such PRINCIPLES OF
IMPOTENCE are COMMON in orthodox modern "science" and help to
cover up INCONSISTENCIES and CONTRADICTIONS in orthodox
modern theories.
Free Energy Inventions are devices which can tap a
seemingly UNLIMITED supply of energy from the universe, with-
OUT burning any kind of fuel, making them the PERFECT
SOLUTION to the world-wide energy crisis and its associated
pollution, degradation, and depletion of the environment.
Most Free Energy Devices probably do not create energy,
but rather tap into EXISTING natural energy sources by
various forms of induction. UNLIKE solar or wind devices,
they need little or no energy storage capacity, because they
can tap as much energy as needed WHEN needed. Solar energy
has the DIS-advantage that the sun is often blocked by
clouds, trees, buildings, or the earth itself, or is reduced
by haze or smog or by thick atmosphere at low altitudes and
high latitudes. Likewise, wind speed is WIDELY VARIABLE and
often non-existent. Neither solar nor wind power are
suitable to directly power cars and airplanes. Properly
designed Free Energy Devices do NOT have such limitations.
For example, at least three U.S. patents (#3,811,058,
#3,879,622, and #4,151,431) have so far been awarded for
motors that run EXCLUSIVELY on permanent MAGNETS, seemingly
tapping into energy circulating through the earth's magnetic
field. The first two require a feedback network in order to
be self-running. The third one, (as described in detail in
"Science & Mechanics" magazine, Spring 1980), requires
critical sizes, shapes, orientations, and spacings of
magnets, but NO feedback. Such a motor could drive an
electric generator or reversible heatpump in one's home, YEAR
ROUND, FOR FREE. [Complete descriptive copies of U.S.
patents are $3.00 each from the U.S. Patent Office, 2021
Jefferson Davis Hwy., Arlington, VA 22202; correct 7-digit
patent number required. Or try getting copies via your local
public or university library's inter-library loan dept..]
A second type of free-energy device, such as the 'Gray
Motor' (U.S. Patent #3,890,548), the 'Tesla Coil', and the
unpatented motor of inventor Joseph Newman, taps ELECTRO-
MAGNETIC energy by INDUCTION from 'EARTH RESONANCE' (about 12
cycles per second plus harmonics). They typically have a
'SPARK GAP' in the circuit which serves to SYNCHRONIZE the
energy in the coils with the energy being tapped. It is
important that the total 'inductance' and 'capacitance' of
the Device combine to 'RESONATE' at the same frequency as
'EARTH RESONANCE' in order to maximize the power output.
This output can also be increased by centering the SPARK GAP
at the 'NEUTRAL CENTER' of a strong U-shaped permanent
magnet. In the case of a Tesla Coil, slipping a 'TOROID
CHOKE COIL' around the secondary coil will enhance output
power. ["Earth Energy: Fuelless Propulsion & Power Systems",
by John Bigelow, 1976, Health Research, P.O. Box 70,
Mokelumne Hill, CA 95245.]
During the 1930's, an Austrian civil engineer named
Viktor Schauberger invented and partially developed an
'IMPLOSION TURBINE' (German name, 'ZOKWENDLE'), after
analyzing erosion, and lack of erosion, in differently shaped
waterways, and developing sophisticated mathematical
equations to explain it. As described in the book "A
Breakthrough to New Free-Energy Sources", by Dan A. Davidson,
1977, water is pumped by an IMPELLER pump through a
LOGARITHMIC-SPIRAL-shaped coil of tubing until it reaches a
CRITICAL VELOCITY. The water then IMPLODES, no longer
touching the inside walls of the tubing, and drives the pump,
which then converts the pump's motor into an ELECTRIC
GENERATOR. The device seems to be tapping energy from that
of the earth's rotation, via the 'Coriolis effect', LIKE A
TORNADO.
A fourth type of Free Energy Device is the 'McClintock
Air Motor' (U.S. Patent #2,982,261), which is a cross between
a diesel engine (it has three cylinders with a compression
ratio of 27 to 1) and a rotary engine (with solar and
planetary gears). It burns NO FUEL, but becomes self-running
by driving its own air compressor. This engine also
generates a lot of heat, which could be used to heat
buildings; and its very HIGH TORQUE makes it ideal for large
trucks, preventing their slowing down when climbing hills.
[David McClintock is also the REAL original Inventor of the
automatic transmission, differential, and 4-wheel drive.]
Crystals may someday be used to supply energy, as shown
in the Star Trek shows, perhaps by inserting each one between
metal capacitor plates and bombarding it with a beam of
particles from a small radioactive source like that used in a
common household smoke detector.
One other energy source should be mentioned here,
despite the fact that it does not fit the definition of Free
Energy. A Bulgarian-born American Physicist named Joseph
Maglich has invented and partially developed an atomic FUSION
reactor which he calls 'Migma', which uses NON-radioactive
deuterium as a fuel [available in nearly UNLIMITED quantities
from sea water], does NOT produce radioactive waste, can be
converted DIRECTLY into electricity (with-OUT energy-wasting
steam turbines), and can be constructed small enough to power
a house or large enough to power a city. And UNLIKE the
"Tokamaks" and laser fusion MONSTROSITIES that we read about,
Migma WORKS, already producing at least three watts of power
for every watt put in. ["New Times" (U.S. version), 6-26-78,
pages 32-40.]
And then there are the 'cold fusion' experiments that
have been in the news lately, originally conducted by
University of Utah researchers B. Stanley Pons and Martin
Fleischmann. Some U.S. Navy researchers at the China Lake
Naval Weapons Center in California, under the direction of
chemist Melvin Miles, finally took the trouble to collect
the bubbles coming from such an apparatus, had them analyzed
with mass-spectrometry techniques, and found HELIUM 4, which
PROVES that atomic FUSION did indeed take place, and enough
of it to explain the excess heat generated.
There are GOOD INDICATIONS that the two so-called "laws"
of thermodynamics are NOT so "absolute". For example, the
late Physicist Dewey B. Larson developed a comprehensive
GENERAL UNIFIED Theory of the physical universe, which he
calls the 'Reciprocal System', (which he describes in detail
in several books such as "Nothing But Motion" (1979) and "The
Universe of Motion" (1984)), in which the physical universe
has TWO DISTINCT HALVES, the material half and an anti-matter
half, with a CONTINUOUS CYCLE of matter and energy passing
between them, with-OUT the "heat death" predicted by
thermodynamic "laws". His Theory explains the universe MUCH
BETTER than modern orthodox theories, including phenomena
that orthodox physicists and astronomers are still scratching
their heads about, and is SELF-CONSISTENT in every way. Some
Free Energy Devices might be tapping into that energy flow,
seemingly converting "low-quality energy" into "high-quality
energy".
Also, certain religious organizations such as 'Sant Mat'
and 'Eckankar' teach their Members that the physical universe
is only the LOWEST of at least a DOZEN major levels of
existence, like parallel universes, or analogous to TV
channels, as described in books like "The Path of the
Masters", by Julian Johnson, 1939, and "Eckankar: The Key to
Secret Worlds", by Sri Paul Twitchell, 1969. For example,
the next level up from the physical universe is commonly
called the 'Astral Plane'. Long-time Members of these groups
have learned to 'Soul Travel' into these higher worlds and
report on conditions there. It seems plausible that energy
could flow down from these higher levels into the physical
universe, or be created at the boundary between them, given
the right configuration of matter to channel it. This is
supported by many successful laboratory-controlled
experiments in PSYCHO-KINESIS throughout the world, such as
those described in the book "Psychic Discoveries Behind the
Iron Curtain".
In terms of economics, the market has FAILED. Inventors
do not have enough money and other resources to fully develop
and mass-produce Free Energy Equipment, and the conventional
energy producer$ have no desire to do so because of their
VE$TED INTERE$T$. The government is needed to intervene. If
the government does not intervene, then the total supply of
energy resources from the earth will continue to decline and
will soon run out, prices for energy will increase, and
pollution and its harmful effects (including the 'GREENHOUSE
EFFECT', acid rain, smog, radioactive contamination, oil
spills, rape of the land by strip mining, etc.) will continue
to increase.
The government should SUBSIDIZE research and development
of Free Energy by Inventors and universities, subsidize
private production (until the producers can make it on their
own), and subsidize consumption by low-income consumers of
Free Energy Hardware.
The long-range effects of such government intervention
would be wide-spread and profound. The quantity of energy
demanded from conventional energy producer$ (coal mining
companie$, oil companie$ and countries, electric utilitie$,
etc.) would drop to near zero, forcing their employees to
seek work elsewhere. Energy resources (coal, uranium, oil,
and gas) would be left in the ground. Prices for
conventional energy supplies would also drop to near zero,
while the price of Free Energy Equipment would start out high
but drop as supply increases (as happened with VCR's,
personal computers, etc.). Costs of producing products that
require large quantities of energy to produce would decrease,
along with their prices to consumers. Consumers would be
able to realize the "opportunity costs" of paying electric
utility bills or buying home heating fuel. Tourism would
benefit and increase because travelers would not have to
spend their money for gasoline for their cars. Government
tax revenue from gasoline and other fuels would have to be
obtained in some other way. And energy could no longer be
used as a MOTIVE OR EXCUSE FOR MAKING WAR.
Many conventional energy producer$ would go out of
business, but society as a whole, and the earth's environment
and ecosystems, would benefit greatly. It is the People,
that government should serve, rather than the big
corporation$ and bank$.
UN-altered REPRODUCTION and DISSEMINATION of this
IMPORTANT Information is ENCOURAGED.

Now this is just ridiculous, the energy industry spends huge
amounts of money scrubbing sulfur compounds out of their
exhaust products and would virtually kill to get a clean source
of energy. Let's assume you are right and these magic sources
work and they have these qualities.
1. nearly limitless supply
2. this supply is effectively free (in terms of cost)
3. non-polluting
4. safe to humans and the environment
The only vested interest the utilities have is to their past investment of
money in their power plants. But the above advantages reduce operating costs
SO much that they would jump at it. (imagine an electric plant that doesn't
need to buy any coal, has virtually no cost related to safety equipment, spends
nothing on environmental technology, and still charges what it used to)==profit!

I've seen this mentioned a few times, and it has me confused.
Any idea why an end-to-end test would have been more susceptible to
gravitational problems than the null corrector test? Couldn't both be
performed with the primary flat on its back? And why are there
more risks of surface contamination?

Whoever did the above adding washers to the test jig probably felt a lot of
time pressure from management to get it done NOW! and don't waste time
about it. He also probably figured the designer made an error overlooking
a small mounting detail, and he could "correct" it easy enough with the
washers, and deliver it as done. And his boss won't be on his ass.
Hell, in my job, I have to deal with a lot of bad documentation, missing
info, lack of proper training, time pressure, bad bosses, not enough time,
and other problems (excuses my boss calles them). Odds are, given time
pressure and bad management, I might have hacked the above mirror tester
to get it done myself. And probably I would have figured I had to make
the "correction" with the washers. And not be able to ask the designer
about it ("he's in a meeting all day", "he's out of town", or some such,
or "can't you figure it out yourself, you idiot").

Subject: Interesting Swift-Tuttle Scenario ...
Newsgroups: sci.astro,sci.space
Here's something to think about. Suppose, after S-T has passed out of
the range of our best telescopes, and good orbital elements have been
obtained, all calculations show a direct hit on Earth is very likely.
However, even then there will be no certainty until S-T is reacquired,
inbound, presumably many decades hence.
What will happen?
Here's my guess: there'll be a flurry of discussion and ideas on how
to divert the comet, but after that everything will die down and the
whole thing will lie dormant (like the comet ;-) -- apart from the
occasional minor study -- until the early 22nd century. Then, the
schemes will be dusted off and re-assessed, some new ones invented,
and -- nothing will happen until either the comet is reacquired, or
the last moment to actually start building something arrives.
Of course, by then S-T could be an exhibit in the Natural History
Museum in Lunar Orbit, or a tour stop on the way to Alpha Centauri ...

At one point I believe that the US was operating a small nuclear

anyone know the details - this would be highly relevant to moon and or mars

There are lots of good references on the Saturn Launch Vehicles.
I'd start with "Stages to Saturn", published by NASA in 1980.
It's reference number is NASA SP-4206. Try a college library, interlibrary

PLANETS
* Mercury is in inferior conjunction and not visible this month.
* Venus is the bright "evening star" in the west after sunset. It
sets about two hours after sunset.
* Mars rises mid-evening in the constellation Gemini.
* Jupiter is the "morning star," rising in the east-southeast
about four hours before the sun.
* Saturn is low in the south at sunset in Capricornus. It sets
about midnight.
EVENTS
Nov. 15: Algol is at minimum brightness.
Nov. 15: Mars is five degrees north of the waning gibbous moon.
Nov. 17: Leonid meteor shower in the early morning hours. Moon
interferes.
Nov. 17: Last quarter moon.
Nov. 18: Algol is at minimum brightness.
Nov. 19: The moon is at perigee, 369,741 km (229,745 mi).
Nov. 20: Jupiter is seven degrees north of the crescent moon.
THE LEONID METEOR SHOWER
------------------------
Most years, the Leonid meteor shower tends to be rather hum-drum.
At most, one can expect to see maybe 10 to 20 meteors per hour
zip fleetingly across the sky from a dark location out in the
country. But every thirty-three years, this shower suddenly
becomes a storm of "shooting stars." The last major storm
occurred in 1966 when observers in the central United States saw
over 5,000 meteors per hour!
Although this is not the year of the storm--that won't happen
until we get closer to 1998 or 1999--the shower still bears
watching because the intensity of the shower should increase the
closer we get to its storm year. Why does a storm happen only
occasionally? The answer doesn't have as much to do with where
meteors are in space as much as it has to do with where comets
are--the sources of the meteors we see in meteor showers.
Comets are like those snow-encrusted cars you often see
barreling down the freeway in winter, leaving in their wake an
icy, blustery trail. When a comet comes out of the deep freeze
of deep space and visits the inner solar system, its surface is
warmed by the sun. Part of its icy crust suddenly turns to
vapor, which blows off the comet's surface, leaving a delineated
path of debris through which Earth passes at a specific time of
the year. The "blowback" material contains ice, dust, and small
gravely material--stuff that later burns up in our atmosphere
during a shower.
The Leonids in particular are composed of debris from periodic
Comet Tempel/Tuttle. This comet has a period of 33.176 years. As
the comet approaches the solar system, it brings with it a
concentrated trail of debris, which Earth passes through. When
this happens, we see a greater display of meteors than usual.
Look for the Leonids on the morning of November 17. Although the
last quarter moon interferes somewhat, the sky should be dark
enough to see some of the brighter meteors. Leo rises in the
east around 1:30 a.m., local time, just as Earth is meeting
these meteors head on. The greatest number, however, will be
seen when the place in the sky from which the meteors appear to
radiate (near the Lion's "sickle") is halfway up in the eastern
sky, and that occurs around 4 a.m.
You can expect to see a half-dozen or more meteors per hour. Then
again, if we pass through a "knot" of debris, as occasionally
happens with the Leonids, you may see a brief flurry of meteors.
Who knows what you may see? I can guarantee, however, that if
you remain in bed, you won't see anything at all.

You don't have to go nearly that far: At 6psi of nitrogen partial

My philosophy on this is better us than them (them being the Russians) As I
see it if we give the satellite to them we will have _some_ control over it.
We will know its abilities, its orbit (if we launch it), its lifetime, even its
radio frequency and computer encoding. With some restrictions/recomendations
we could at least try to make sure the UAE don't use it for purposes contrary
to our national interest.
On the other hand we could refuse. Odds are that if they really want a
satellite they could get it from the Russians. It is not even like they are
asking for top of the line (2m resolution isn't that great if you believe some
of the rumors about our 'real' spy satellites) The Russians have already
started selling photos what is to stop them from selling a whole satellite?
And in this case we would barely know anything about it. Of course if the CIA
can insure us that the UAE will definetly not buy a sat from the Russians then
there is nothing to worry about right?
And better that the 'first kid on the block' with a spy satellite be someone we
at least can kind of trust, and is politically stable (for now)
Oh, and there's always the famed jobs question, which applies to both Russia
and the U.S.
