Subject: Space Anniversaries



There are a couple of space anniversaries coming up.  Today (May 4) marks
the first anniversary of the Magellan launch from the Space Shuttle.
Tomorrow is the 29th anniversay of Alan Shephard's flight into space,
the first U.S. astronaut in space.

By paper projects, I doubt you are referring to the use of paper-like

Seriously, though, this is a horrible state of affairs;
Is there possibly a way to get NASA involved in helping prove out the

helped Pegasus? (Question: Exactly how much did DAPRA/DoD help
Pegasus?)

Subject: Voyager Confirms Relativity




From Sky & Telecope, June 1990

VOYAGER CONFIRMS RELATIVITY

When photons escape the gravity of a massive object, they lose energy and
their wavelengths increase correspondingly.  Such a gravitational redshift,
amounting to just one part in a billion or so, was measured by Timothy P.
Krisher and colleagues at NASA's Jet Propulsion Laboratory.  They used
tracking data from Voyager 1's flyby of Saturn in 1980.

Their results, reported in the March 19th Physical Review Letters, confirm
the predictions made by the general theory of relativity to an accuracy of
1 percent.  Krisher and co-workers are now refining their observations using
Voyager 2 data from Uranus and Neptune.

Darn right it would have to be modified.  Apollo 204 is not just "nearly
identical", it *is* identical, right down to the scorch marks and ruptured
hull.

That thing belongs in a museum, not in space or in a missile silo.

I heard a radio report, I believe on NPR, that 204 was going into the
same silo, and that the move was made to free storage space at Langley.

"Cultural?" If the selection of target were ruled by a cultural point
of view, it should be Mars. Remember Schiaparelli's and Lowell's
'canals'? H.G.Wells' "War of the Worlds"? Orson Welles' broadcast in
1938 that caused major panic in New England? The speculations
of life forms that prompted researchers to include a life-detection
experiment on the Viking landers? Venus may be the "TRUE twin" of Tellus
mass-wise, but as far as the climate and possiblilty of life (as we
know it, Captain :-), Mars is definitively closer.

Sure, in a lab on Tellus surrounded by cooler air... A question was
previously discussed on this newsgroup: "where do you dump the excess
heat to cool the lander?"

Mars is definitively a better choice for manned landings. The mission
can be carried out at considerable less expense (despite the longer
distance) since all the life-system technology already exists. A
"mars-suit" wouldn't be much different from a "moon-suit" the Apollo
astronauts used. (Of course, the blueprints of the suit might have
been chucked away along with the rest of the Apollo hardware :-(

Still, a manned Venus-lander would be instructive to launch, if only
to prompt the development of ultra-resilient life-support systems :-)

There are size limits for being an astronaut, on both the large and small
ends, to avoid having to design equipment for extreme-worst-case people.
They've loosened a bit over the years; the original Mercury maximum height
was set by the diameter of the capsule!

The idea of specifically selecting small people to reduce equipment size
and life-support requirements has been mentioned occasionally, but NASA
has never taken it seriously.  About the only example I know of in real
life, in fact, is that the Soviet Army specifically selects small men
for tank crews.  (They have the advantage of having universal conscription
from a huge population, guaranteeing an adequate supply of small people.)

One more comment (sorry about wasting the bandwidth):

Larger markets probrably won't evolve with the current ultraexpensive
(X thousand a pound? Whatchya doing? Using gold as reaction mass?)
rockets we are currently using. Solar Power Sattelites, SDI, et al
all seem to be waiting for a cheap lift.

Subject: EVA comm during Hubble deploy
Date: Fri, 4 May 90 13:13:06 MESZ
From: Joseph C. Pistritto <[e-mail]>
Mailer: Elm [revision: 64.9]

The astronauts were in the airlock, and partially depressurized
during the Hubble deploy problems (solar wing).  I suspect that
the shuttle air to ground was being patched thru onto the suit
comm frequency during this time, so that Houston could talk
directly to the astronauts.  This would certainly seem the most
efficient way to get everybody on the same line.  Since the
orbiter antenna would be radiating on the suit comm frequency,
I suspect this is what was monitored by the ground station
involved.  Assuming that thing puts out 1 watt or so, its very
reasonable to be receiving it on the ground from a receiver
like the R7000.

"Moonport" (NASA SP-4204), the definitive history of the Apollo launch
facilities, discusses the ventilation system that was provided specifically
to avoid condensation problems and the like within the VAB.  Rocco Petrone's
chapter in "Apollo Expeditions to the Moon" (NASA SP-350) (Petrone was in
charge of Apollo launch facilities during much of their construction and
early use) does mention the "clouds" -- as baseless folklore.
