The IR system was indeed a development item flown as an experiment, but
it hasn't become a regular part of the operational system.
We bought a small IR system during SSF advanced development, but it
didn't work well. The main drawback I saw to the IR was the much
greater battery power required in the mobile unit compared to RF. The
obstruction problem was not quite as bad as I had thought it would be
but was significant nonetheless. It might be worth revisiting
someday. I never saw the Shuttle IR system and never saw any reports
on it. It probably worked better; the little system we had was a
rather poorly constructed breadboard.
There is a floating mike which became part of the operational system,
however, and I'm not aware of any connection it has (physically or
programmatically) with the IR system, although there obviously might
have been. One or two astronauts (can't remember who) insist on the
floating mike.
The current wireless crew comm system uses UHF frequencies carefully
chosen between 350 and 400 MHz. Two channels isn't exactly right, but
there are only two audio channels to/from the ground, so that's close.
8-) There was an older (and rather kludgey) wireless system which was
used from STS-2 through 51-L; maybe it only had two channels. I can't
remember that either.
I don't think the EMU's have IR or anything really advanced in the way
of comm equipment. They were using UHF radios dating back to the
Apollo program last time I looked; they worked somewhere around 250
MHz. There is a new comm system being developed for the Shuttle and
SSF, but it too is UHF (TDMA, though!) somewhere between 410-420 MHz.
This would be used in the EMU's.
A not unrelated factor in all of this is that DoD is forcing (in the
nicest possible way 8-) NASA out of the band of UHF frequencies we've
used in the past. There is some limited "grandfathering" of the old
systems, so it's perhaps not quite as drastic as that.

_Fallen Angels_ is by Larry Niven, Jerry Pournelle, and Steven Barnes.
Niven and Pournelle have done many many other books together, such as
_Footfall_, _The Mote in God's Eye_, _The Gripping Hand_, etc.
They also formed the Citizens' Advisory Council on National S[ace Policy,

My problem was in using an older version of NIH Image. I couldn't make my
puny 8 megabyte RAM Mac IIci display more than 33 frames of the movie
using the correct version of Image and throttling back to System 6.0.7.
The improvement is that there are 256 gray levels, while Popcorn under
Quicktime seems to have eight or sixteen. Those with small RAM capacity
should be warned not to try too hard to get the movie running at full

Subject: Gravity-NEUTRALIZING Spacecraft
Newsgroups: sci.space
The ZERO/REDUCED-Gravity Chamber described below has obvious potential
applications for Chemistry, Biology, Biophysics, Biochemistry, Medical
Research, etc., allowing experiments which now can be done ONLY on the Space
Shuttle, AT GREAT EXPENSE!
Gravity-NEUTRALIZING Air/Spacecraft
or ZERO/REDUCED-Gravity Chamber
NASA should build an experimental spacecraft based on
U.S. Patent #3,626,605 [at least $3.00 per complete copy from
U.S. Patent Office, 2021 Jefferson Davis Hwy., Arlington, VA
22202; correct 7-digit patent number required. Or try getting
it via your local public or university library's inter-library
loan dept..], titled "METHOD AND APPARATUS FOR GENERATING A
SECONDARY GRAVITATIONAL FORCE FIELD", awarded to Inventor
Henry W. Wallace on Dec. 14, 1971.
In the patent, Figs. 7A and 7B are basically side views
of a gravity-NEUTRALIZING FLYING SAUCER, or, if anchored to
the ground, a ZERO-GRAVITY CHAMBER [which could have MANY
possible GROUND-level applications for science, medicine,
manufacturing, etc.]. Each oval diagram shows a motor
spinning a central disc at a very high speed, about 28,000
RPM, and also rotating two other discs sandwiched around the
first disc, via gears, at a much slower speed, perhaps 2,800
RPM, in the opposite direction. The two outer discs have
extensions [counter-balanced via off-center axis] that, as
they rotate, alternately make contact with two wide
extensions from opposite walls of the spacecraft. The
central disc should have shallow spiral-shaped grooves on
both sides for air-bearings, to allow the needed very close
contact with the two outer discs.
I should clarify that each of the two outer discs has
ONLY ONE [counter-balanced] extension, each one pointed
opposite (180 degrees) the extension of the other disc.
VERY CLOSE CONTACT must be made as the disc extensions
slide past the wall extensions in order to conduct the
"Kinemassic" Energy (term coined by the Inventor) from the
discs to the walls in an ALTERNATING CIRCULATION.
The most important factor making it work is that the
discs, extensions, and outer walls of the spacecraft MUST be
made of any material(s) in which a very large majority of the
atoms are of isotopes having "half integral atomic spin",
such as copper (3/2). All other parts, etc., should have a
minority of such atoms. [See the appropriate column of the
table of isotopes in the latest edition of "The Handbook of
Chemistry and Physics."]
Experimenters should use one motor to spin the center
disc, and a 2ND SEPARATE motor to rotate the two outer discs,
so their relative speeds can be varied to establish the
needed conditions for PROPULSION of the spacecraft via
"NEGATIVE WEIGHT" (with the spacecraft's "Kinemassic" field
PUSHING AGAINST the earth's gravitational field, etc.).
If we have to put up a space station, establish Moon
bases, go to Mars, rendezvous with comets, etc., WHY DO IT
THE HARD WAY?!
Your favorite university or research company could make
a big name for itself by making a small model of this work.

Further support: my CRC gives 300 ppm (or grams/ton) Fluorine, 65 ppm Lithium
in the earth's crust. That should give some indication of how common they'd
be on the moon.

Nothing about an IV *requires* gravity; raising the IV bag is just a
convenient way to overcome the venous pressure (6 mmHg or so).
There are occasions where docs want to place an arterial catheter.
Here the pressure is so high that gravity is impractical, so you just
pressurize the bag externally using a sleeve much like a blood
pressure cuff. The same thing would work for an IV in space.
Keeping bubbles out of the line would be a trick....

Historical Tidbit: The first plane to receive the designation A-12 was
the precursor to the SR-71. the A-12 was operated by the CIA.
As for rumoured replacement. The SR-71, the A-12, the F117A were secret for
many years before they went public. So it is reasonable to assume that
the USA has a replacement. After all the original designs for the SR-71
dated from the late 40's. You decide.

I can't say that he's always wrong, but he usually is. The shuttle flies at
different attitudes for different missions. It often flys with the payload bay
pointed at Earth so that astronauts and payloads can look down. Sometimes,
as with the TSS mission, it flies with the cargo bay pointed up. I believe it
also uses a gravitational gradient mode, with the tail pointed at Earth on
occasion. This is useful when you don't want to use the thrusters since it's
a naturally stable position. The shuttle does fly fixed with respect to the
stars when it's trying to observe them, such as during an astronomy mission.
However, I'm not aware of any other reason why it would do so.

Nick pointed out in e-mail the embarrassing fact that I'd used the
wrong radius for the Sun's orbit around the barycenter; for
Sun-Jupiter it is 743,000 km, resulting in an orbital speed of 12.5
m/second, so his figure above is correct.

Subject: Why Apollo didn't continue?
Newsgroups: sci.space
Is there any good references about the Apollo Appications Program (AAP)
and the lunar exploration followups after Apollo?
I read a little about these topics in 'The History of Manned Space Flight',
by David Baker, but it could be nice to read a more elaborated reference
on the subject.
