Eric, if the Martian capsule on a multimonth duration
round trip journey resembles _a full barrel_ because
that is all that is affordable, we got new problems.
Have you ever visited the Smithstonian Air And Space Museum
in Washington DC, Eric? Have you ever touched the moon rock?
A moon rock is embedded in a massive pedestal -- less than
one square inch surface area is exposed. (Think Excalibur,
Eric.) The Apollo astronauts did not bring back _tons_ of
moon rocks, Eric, because they had mass limitations upon
return. I consider that the precedent, Eric, and compared
to Mars the moon is nearby and has low gravity.

Golly, Eric, I misspelled a word. Imagine that. I must have
been distracted by my breakfast. I'm glad the misspelling
is in casual text rather than in an operations manual (or
worse, in a computer program).

This ain't lasers, Eric -- no solar sail spacecraft launched
by Moon-based lasers ala Larry Niven. All fuel must be carried
aboard the mission with no resupply. Ditto with food, drinking
water and a source of breathable air. No stasis fields ala
Larry Niven -- ya gotta eat, ya gotta drink and ya gotta breathe.
Science fiction plots often center around 'if that technology
existed, how would this social and/or physical environment
change?'. I assume no fundamental physics or medical
breakthroughs between now and the launch of the human mission
to Mars. IMO new pharmacuticals or genetic engineering will
not be relevant to the problems encountered on the Mars mission.

Did you lose your sense of humor, Eric? Perhaps you were
distracted by _your_ breakfast. Given the choice between not
important misspellings and loss of sense of humor, I'd choose
the misspellings every time. Of course I'm just hacking on
Usenet -- I am not an astronaut depending upon a space capsule
to keep me alive on a round trip voyage to Mars.

There have been _no_ multimonth space journeys conducted
in the equivalent of the Mercury/Gemini/Apollo spacecraft,
Eric. I am _not_ convinced that more spacious accommodations
will be affordable on a mission carrying humans to Mars.

There have been NO multimonth continuous experiments
without _resupply_, Eric. Think of an oceangoing
wooden sailing ship departing for the new world.
What ya got is all ya get until you return -- there is
no food on Mars, no drinking water (to my knowledge),
the Martian atmosphere is not breathable (to my knowledge)
and no fuel supply on Mars (to my knowledge).
Almost makes you wonder if a Martian voyage might be
preceded by a mission that achieves Martian orbit with
the sole purpose of resupply once the capsule carrying
humans arrives in Martian orbit -- get the groceries,
etc. to Mars first safely.

If I 'right' must I reserve?
I got no problems.

[RB comment: Provided both to ABIA and ABLN ]
IMO former President Kennedy's decision to land Americans
on the moon (a decision that several successive Presidents
supported) initially was a response to the Cold War and to the
Cuban Missile Crisis. IMO President Kennedy's decision was
a de facto extension of the Monroe Doctrine to near space.
The Mercury / Gemini / Apollo programs brought great advances
in computers, in materials science and in biomedicine, but
IMO these programs were _not_ initiated as science investment
programs. Americans like NASA, but IMO these programs were
initiated to accomplish United States dominance of near space.
I observe no equivalent motivation for a mission carrying humans
to Mars -- I observe no equivalent cost justification. As a result,
I believe that economic analyses will be _very_ important to the
hu/manned Mars missions' design and implementation.
And as I alluded to earlier, I observe no relevant _fundamental_
scientific discoveries since the Apollo program. No Star Trek
transporter and energy-to-matter transmutation for resupply.
Star Trek's gravity generators (which raise interesting
inertial mass reduction questions) do not exist. We will be
applying faster computers plus Apollo technology to a Mars
mission. [Deep space telecommunications capabilities might
have improved -- greater power in a noisier terrestrial
environment (e.g., cellular telephones).] I know no
_relevant and significant_ materials science or biomedical
advances since Apollo. IMO new pharmacuticals and genetic
engineering are _not_ applicable to the Mars missions'
_major_ problems.
That is why I (a taxpayer) keep asking "What can we afford?"

When a wooden sailing ship set out to find new worlds, there
was no guarantee the crew would find land. If they found land
there was no guarantee the crew would find fresh water -- the
coastline might be desert. And there was no guarantee that
the crew would catch a significant amount of fish. There was
no resupply guarantee in a wooden sailing ship seeking
new worlds.

As I mentioned earlier, I am _not_ qualified to provide dental
opinions. To my knowledge tooth enamel is not subject to
calcium leeching by the body.
I am _not_ qualified to provide medical opinions, but I know
that in cases of dietary calcium deficiency the body can leech
soluble calcium from the bones, weakening bone rigidity and
strength (e.g., osteoporosis). I do not know how long this
process takes, and whether the effect would be serious on
a several month long space journey.
As I mentioned earlier, I am _not_ qualified to provide medical
opinions, but I seem to remember that the opposite problem
exists: the formation of dysfunctional calcium deposits in
unused skeletal joints. A sedentary (e.g., bedridden) individual
can get calcium deposits in their skeletal joints, simulating
arthritis. I do not know if astronauts forced by tight quarters
to continually recline on acceleration couchs with no physical
exercise would experience these skeletal dysfunctional calcium
deposits during a several month space voyage.
Too little dietary calcium and astronauts might get calcium loss
in bones with resulting loss of skeletal strength. Too much dietary
calcium with no physical exercise and astronauts might get
dysfunctional calcium deposits in joints with resulting motion
pain and problems. I do not know the rate at which these maladies
occur -- presumably space medicine and geriatric medicine already
knows the answers.

Eric, I tire of your childish denials.
As I mentioned earlier, excessively tight underwear elastic
can chafe your skin in any environment. And acceleration
couches are designed to cushion against forces generated
by rocket thrust in addition to gravity (if any).
And there is no Star Trek transporter to beam supplies aboard
a Mars mission craft from a remote location -- no resupply
without a separate advance resupply cacheing mission.

Skylab had a shower, Eric. I do not know the history of Mir, but
I know it is bigger than the Apollo spacecraft -- room for spare
clothing and for washing and changing clothing. Ditto the
International Space Station even in its early stages. And both
Mir and the International Space Station get resupplied.
Eric, some naval vessels have oceanwater showers -- they can
not afford to waste fresh water for showers. This indicates to
me that spacecraft might have similar fresh water problems.

I am skeptical, Eric. I seem to remember discussion of souvenir
dimes and postage stamps that somebody stowed aboard one
of the Lunar Landers. And that Smithsonian moon rock is awfully
tiny -- if we had 400 kg. of moon rocks IMO the Smithsonian would
merit a bigger sample (for the viewing taxpayers).

The lunar journey is much easier than the Martian journey.

Eric, my economics-based opinion is that the majority of
any hu/manned voyage to Mars will be spent wearing
relatively uncomfortable pressure suits with the possibility
of chafing complicated by difficulty in eliminating bodily
wastes and in washing. Constipation could be a problem if
fresh water rationing is necessary -- things happen on a
multimonth voyage without resupply. And pressure suits are
not double knits, Eric -- you don't just slip them on and off.
Eric, the last two decades of the United States hu/manned
space program have been near space using the Space Shuttle.
From a volume ergonomic standpoint the Space Shuttle is roomy.
Now the United States is discussing a hu/manned voyage to
Mars, and I am _not_ convinced that we can afford to provide
Space Shuttle quality accommodations on a hu/manned Martian
mission. In a sense we are going back into the engineering
archives, dusting off the Apollo records and restarting.
I know _no relevant fundamental scientific or engineering
breakthroughs_ that have occured since the end of the Apollo
missions. Faster computers and better (?) communications
are not major helpers on a Martian mission.
I do _not_ observe political or economic motivation for deluxe
accommodations on a Martian mission-- the United States domestic
economy is weak and it is increasingly difficult to justify pure
research not designed to answer specific questions with economic
payoffs. (As a counterexample, the Space Shuttle is the spacetruck
that allows the United States to maintain its near space
infrastructure -- telecommunications, etc.) And I do _not_ observe
relevant scientific or engineering breakthroughs since Apollo.
Motivation and breakthroughs are the _relevant_ topics, Eric.
Address those two topics, Eric -- your uncorroborated denials
do not warrant wasting my time.

On the theme of 'Things Happen', I merely will reference the
wonderful space film "Silent Running" starring Bruce Dern.
In a long space voyage some contingencies will _not_ be
anticipated and some spare resources are necessary -- you
can not burn all your resources before liftoff.

Bone loss (in the jaw which can cause tooth looseness and loss)
does _not_ equate to tooth decay. Teeth are different material

Richard if you did the smallest amount of research you would know what
the current plans for a Mars mission are, which will change a lot
since a human Mars mission is still decades away. Then you would not
look so stupid with your nonsensical ramblings.

I started this thread with a simple ergonomics question.
The thread degenerated into a flood of insults.

"I am not qualified to provide opinions ..." is a fairly standard
legal disclaimer. It means "I do not warrant your results if
you utilize the information I provide." Unlike the plethora
of instant experts I encounter on Usenet, I state "I am not
qualified ..." repeatedly. I fear that Usenet/WWW is many people's
primary source of serious information (T V is _not_ organized by
topic) and many people act on their Usenet/WWW readings without
further research. I have encountered much bad medical opinion
provided by laypeople on Usenet.
I also view websites critically. A website can be hosted very
economically, websites can present information advancing hidden
agendas, website information is easily changed with no archival
audit trail, and there is no independent review of website content
or website information quality.
That covers the legalities. As to your aversion to me personally,
you have two options: 1) Knowing that I provide Usenet messages
using only one email name ('RBall84213@aol.com') you can
killfile me and never be annoyed by me again; 2) You can use
insults and ridicule in a de facto attempt to censor me, and I
will laugh in your face.
Option 1 is easier for you, more pleasant for everybody and
does not waste _my_ time (which covers the rest of your
objections).
Arrogant? Perhaps. To put my attitude in perspective, I
reference Larry Niven's comments about Louis Wu. Louis Wu
was intelligent, but Louis Wu had years' experience that had
taught him economy and safety of movement. In an era of
perfect cosmetic and functional surgery, Louis Wu could
recognize other people with years' experience by their
motions and mannerisms.
I am _not_ a physician or a dentist, but I still have my body
and I still have my teeth. Lessons and information I have
learned along the path continue to help me keep both. I
will not hide like a mushroom because I do not have a medical
or dental degree -- mushrooms rot quickly.

Tooth enamel is (relatively) brittle -- it chips and cracks.
These characteristics make enamel not suitable for
(load bearing) bone.
I am not going to waste my time arguing about something
that is not there.

My understanding is that once your teeth are formed
they grow no further. Your adult teeth replace your
infant teeth, and dental caries do not heal -- broken
bones heal. Apparently some antibiotics inhibit
formation of strong teeth.
To my knowledge the body can _not_ leech calcium
from your tooth enamel, but in cases of calcium deficient
diets the body can leech calcium from the jawbone sockets
that hold the teeth, weakening the anchoring of teeth to
the jawbone.
I also seem to remember that the masseter (the muscle that
operates the jaw) is the strongest (per cross sectional
area) muscle of the body, but I'm fuzzy on this fact.
I am _not_ qualified to provide medical or dental opinions.

Calcium is a chemical component of tooth enamel.
To my knowledge the body includes no _systematic_
mechanism to leech calcium from tooth enamel.
Most people are aware of the existence of osteoporosis,
a condition of bone weakness in humans with
calcium deficient diets. Osteoporosis can occur late
in life to a formerly (skeletally) strong individual.

"... hidden agendas ..."? How can (correct?) information advance
hidden agendas? I'd argue that the context in which information
is presented modifies the information content. The same information
presented in two radically different contexts can lead readers to
two radically different conclusions.
Bugs Bunny provides an example. Everybody loves Bugs Bunny
and everybody knows his sarcastic catch phrase:
"Ehhh, What's Up, Doc?" How many people have pondered the
meaning of "What's Up, Doc?"
As a kindergartener in the 1950's I had a 78 RPM vinyl record set
"Bugs Bunny In Storyland" which included a selection "What's Up,
Doc?". This selection now is out of copyright and the lyrics were:
"What's up Doc?
What's cookin'?
What's up Doc?
Oh you're lookin' ...
for Bugs Bunny bunting,
Elmer's gone a-hunting,
just to get a rabbitskin ...
oops, the rabbit's gone again!
What's up Doc?
What's cookin'? ...
You're gonna hurt someone
With that old shotgun ...
Eh, what's up Doc?"
What does this mean? I do not know what it means
in the 21st Century, but in the 1950's people talked
about "having a bun in the oven" (cooking) and about
shotgun marriages.
IMO context is everything.

When people grit their teeth (misuse) the teeth sometimes

Wrong answer -- sometimes I am overqualified.
IMO "I am not qualified ..." is a context-dependent
localized caveat.
