Newsgroups: sci.astro,sci.space
Regarding the discussion on the Alvan Clark telescope:
In the May 1990 issue of the Electronic Journal of the Astronomical
Society of the Atlantic (EJASA), Volume 1, Number 10, there is an
article by Alan Fleming on a 1988 visit to a 58-centimeter (23-inch)
Alvan Clark refractor at the Roper Mountain Science Center's Charles
E. Daniel Observatory in Greenville, South Carolina. The article is
titled "A Living Legend: The Alvan Clark Refractor".
The May 1990 EJASA is available (as are all other EJASAs up to
January 1993) from the ASA anonymous FTP site at chara.gsu.edu
(131.96.5.29). If you cannot access the site, please let me know
and I will E-Mail the issue to you.

I agree. The problem is that this cannot be proven to the degree needed
to justify the opportunity cost of funding development. If you don't

I'm only repeating what I heard, but I think it's fairly obvious
they were talking about regulation (and maybe a guarantee that
the government would not build something to compete with them).

Grumman's bid was declared ineligible because it was not technically
single-stage-to-orbit. (It's air-launched from a 747.)

Oh? Really? I could have sworn I saw an ad in this morning's

Your first idea would be good on an arctic expedition, or
even on a lunar traverse, but not on a trip to Mars, since
everything bewteen here and there ALSO has to be revolving
around the Sun: different distances from the Sun = different
periods of revolution. You could drop stuff off evenly spaced
between here and Mars, but when you got to that distance, they
would no longer be lined up, having travelled along their
orbital paths since they were left.
The second idea of sending some sort of resupply craft ahead,
and parking it in Martian orbit where you could find it,
redezvous with it, dock and transfer from it, is a MUCH better
suggestion!

Your right George, the second is more fesible.. Maybe a multiple stage
pre-positioning nission.. Why must the big stuff, the extra food/supplies be
sent with the quick human mission.. The slow part can
get there a year or two before the human mission, and maybe act as
a sensor, launch probes and such and maybe act as a NAV bouy..
And maybe do other missions that would make the human mission easier..Do the
things that humans don't need to do..
Question what would you use to get it there?? Automated Solar Sail would be
nice.. Seems you only need rockets and such when you have to get someplace
quick.. The auto-mission would do surveys of possibel landing/survey sights..
Any better ideas are expected..

Subject: Mir mission to Mars?
The major problem with using Mir for a manned Mars mission
is that Mir is not designed to protect its crew from the
interplanetary radiation environment.
At most times in the solar cycle, there would be a near
certainty that any unshielded astronauts on a two
year mission to Mars would be killed by solar flares. (At
the minimum of the cycle, the astronauts might make it
--some years have no major flares)
Adding a shielded "storm cellar" to Mir could greatly
reduce the danger. Probably about 25 gm/cm^2 of shielding
would be needed to allow the crew to survive a major flare
in fairly good shape - extra mass would be roughly:
25 gm/cm^2 * 2*pi*200cm * 200 cm = somewhere around 6,500
kg for a 2meter long, 4 meter diameter "cellar".
Of course, there's also the cosmic ray radiation dose,
which is much more difficult to shield against and is
about 20-40 REM/yr depending on the time in the solar
cycle (more or less inverse to the flare probability)
This is below, but close to, the annual limit allowed for
shuttle astronauts (50 Rem/yr last I heard)
For more details I recommend looking at the AIAA's report
on assessment of technologies for the SEI -- it has a
lengthy section on the need for shielding and the effect
on total mission mass.

Such a mission would hardly seem worth it from a scientific stand-
point. Is there *any* science that could be done on such a mission
that could not be done more cheaply and safely by a robotic craft ?
(Bioscience sure, but can't that be done in Earth orbit ?)
And BTW, does the data re. the long-term deleterious effects of
weightlessness (such as loss of bone mass) point towards use of
a tether to create 0.X G on a Mars mission ? What kind of elec-
trical energy could such a tether generate by its rotation ?
Enough to justify the added gear ?

I realize this is almost ten days old and I don't know if anyone
has replied yet. Hey, it's tough keeping up with 100K of traffic

Have you tried the National Archives (NARA) yet? Perhaps some
Mercury material has been moved there, by now. All government
branches routinely deposit material of this type, including NASA.
NARA publishes a periodic listing of new deposits. I try to post
any new NASA-related deposits to this newsgroup.
If I lived where you live, I would try contacting the New Jersey
Regional Branch of NARA. For anyone else who wishes to pursue this
type of research, I am including the address and phone of each of

I assert that if the station fails because Spacelab spent the $$ which
should have gone to proper integration testing then they will have a
lesser degree of success.
Spacelab tells us something about one of the many uses a station may
have but it doesn't tells us about building stations. It's like saying
refrigerator research is an important precursor to house design because
one of the things people do in houses is cook food. It's true that most
people want refrigerators in their houses but houses can be built
without them.
I understand your point but I think you are bluring the distinction
between an object and what it is used for.

Allan if you have looked at any of the information that has been put out
about SSF in the last decade you will see that the PRIMARY mission of
SSF is to be a laboratory in space. This applies to materials processing
as well as biological sciences. The Astronauts will actually be in the
role of highly paid and trained experiment tenders and guinea pigs for
research that will help us understand how human beings adapt to long term
weightlessness.

Assert all you want but this is not the case. Spacelab began over ten
years before Ronnie made his call for the Space Station. All scientists and
engineers agree that precursor testing is an absolute necessity in perfecting
the methodology and proper engineering for the experiments to enable them
to be successful on station. I assert that this is what we in the computer
world call subsystem testing. This subsystem testing enhances the reliablity
of the total system by allowing the testing of the individual components,
methodologies, and processes that will be used for Space Station Freedom or
any other manned orbiting outpost for that matter.

Allen building SSF or any other large structure in space is a mere engineering
exercise that we learned long ago. There are no mysteries involved in the
process. What the precursor missions of Spacelab, SpaceHab, COMET and CONSORT
get us is a REASON for building these large structures in space. Without a
reason for existence other than the mere effort of building the structure,
we get yet another Apollo, and yet another boondoggle that is useless in
helping to advance the knowledge, understanding, and welfare of the citizens
of the United States and the world.

I think you misunderstand the point Allen and the point of the original post,
which had to do with precursors to SSF. The point of the precursors as I have
and Bill has laid out is that without proper testing at an early stage of the
process, which we do have in the programs that I have mentioned, you have
a great mass of expensive metal in the sky that is simply useless for anyone
other than the mechanical engineers who design them. Your analogy of the
house is an apt one. A house may keep you warm and dry, but if it is empty
or the television does not work and the bed is broken and the lights don't
work you only have an empty shell which does nothing for the occupants or
the people in general.

Actually, if you look at the information that has been put out about
SSF in the last decade you will see that the PRIMARY mission of SSF is...
A. Life science (at least to the life science community).
B. Microgravity (at least to the microgravity people)
C. Assembly point for Moon/Mars (At least to the manned space crowd)
D. A mechanism to teach us how to live and work in space (at least to
the space colonization crwod)
E. Well paying jobs for your district (at least to Congress).
F. (insert your favoriet special interest here)
In short, Fred was to be everything to everybody. Your belief that
a particular one of these was actually (we mean it this time) the
primary mission requires very very selective reading of history.
>Allen building SSF or any other large structure in space is a mere engineering

So why is the truss work package over a billion over budget and still
out of control? No Denis, since nothing like this has ever been build
in space before it cannot be called 'mere engineering'.
>There are no mysteries involved in the process.
Except for why in hell it takes twice as long and costs three times
what it is supposed to. (Although given NASA's poor performance in
almost every aspect of cost estimating and management maybe this
isn't that strange).

You mean aside from keeping them warm and dry? Most would consider a
house which keeps you warm and dry a resounding success. I myself would
prefer the above to a house which is cold and wet but has a working
television. Especially when you realize that the TV won't last long
in the wet house.

scruteny than the normal 747. Also the Commerical liner has a schedule to meet,
also it just migth have better I think that if the DC-X flys, it will quickly
become commercialized.
Nice to see scheduled airline flights into orbit....
Other thing is that Military Aircraft are also dependent public and also
congressional views/needs..
REF: 747 versus C5 competition, 747 was competing with the what is now called
the C5, the C5 won and 747 became a major airliner with a good record.
One of the standard possible reasons for the C5 getting picked was more due to
the fact that the Congressmember who had the finger on the ppurse strings was
from the home state of Lockheed, which was going thru a hard times job wise..
So maybe the Shuttle is here because of more than need for space
but of economics?? and power plays..

Sounds liek what is needed is to convince the US population that Space is where
we need to go.. Sounds like NASA needs to spend more on Public Relations.
Maybe get a news network involved. maybe have them do some mnor sponsorship of
some space related high profile TV programs/Cable to. Such as Star Trek
(TNG/DS9). I am finding that if a major news netowrk is on your side, you can
do alot of things.. REF: Clinton.. and somewhat Perot.. I know of other third
party candidates who can't get to square one, but Perot comes out of obscurity
to where people want to know what he ate for breakfast..
Maybe also try to have some space/science programs on mainlien TV..
Also start or help local quality TV organizations, namely cause of what I have
seen the basic bent for modern TV is a prime help for the lack of science in
the current crop of students..
Im not talking violence, Im talking about who is cool and who is not..
Scientists many times are not cool, they are egghead, nerds, geeks and such..
Bumbling social idiots.. (I might be wrong)..

Come now, Paul...isn't it a relief to have the secrets of the universe revealed
in this way by Mr. McElwaine, whose prose possesses such clarity of thought,
such an enlightened vision, such...such...
BULLSHIT!
