Nowhere do either of these two citations mention the word ENAMEL,
the subject under discussion.
Broken bones heal, while broken enamel does not heal --
a significant and obvious difference.
I am not interested in discussing dentistry details.

Information also must be interpreted correctly.
Neither of your two cites mentioned the word enamel.
And in a different message you admitted that dentin
(the subject of discussion in your citations) did not
equate to enamel.
You interpreted two citations incorrectly prove a point about enamel.

Dentin does _not_ equate to enamel, and the word ENAMEL
appears nowhere in these two citations.

Stacy <haponik+pleasenospam@wpi.edu> writes:

COMMON SENSE:
Broken bones heal -- broken enamel does not heal.
This is a significant and obvious difference that does
_not_ require Internet citations and research to understand.
I am not interested in further discussing
dentistry or your research qualifications.

I originally asked this question because IMO economics will
force tight quarters on a hu/manned Martian mission. My
initial impression is/was that public opinion believes we will
build the USS Enterprise to go to Mars. IMO the implementation
will resemble Apollo more than it resembles $tar Trek.
Lvpokerplayer.TakeThisOut@aol.com (among others) has since provided
specific technical details of proposed lunar launches supporting
the Martian mission -- technical realism. IMO launch from
Earth orbit might be equally feasible and less expensive, but
I am not qualified (and do not have the time) to work the details.
IMO the infrastructure required for an Earth orbit launch might
have greater reuse potential -- an important selling point for the
taxpayers and for Congress.
Ironically, MSEE can denote Master of Science in Electrical
Engineering (that's me), or it can denote the NASA position
designation Mission Specialist Environmental Engineering --
that is, an ergonomics (human factors) specialist. IMO
current public discussion of the Mars mission is _not_
emphasizing ergonomic reality. The human body did _not_ evolve
in near zero gravity cramped quarters and this environment
impacts human physique adversely -- important both to
successful mission completion and also to astronaut health
and safety.

I am sure that you are familiar with the wonderful space film
"Silent Running" starring Bruce Dern.
Your ideas sound spacious and expensive. How would you
market these ideas to the taxpayers and Congress?

Adaptation is not the issue.
Not making messes is the issue.
For example, if you walk around unzipped and exposed
you should not expect others to adapt to your behaviour.

'Tight quarters' is a relative term, but I believe
economics will make the implementation look more like
Apollo that like the U$$ Enterprise.
IMO an 'Apollo style' Mars mission makes the mission riskier
but less costly. I assume some common sense is included in
the implementation decisionmaking process.
Cost versus risk is a standard trade in systems engineering.
Cost versus benefits achieved also is a standard trade
in systems engineering.
System engineers quantify -- they seldom are responsible for
making the final decisions.

I did _not_ discuss rescue missions. I discussed (re)use of
the Mars mission logistics infrastructure in other productive
capacities. For example, I might purchase a personal computer
for business use, knowing that I also can catalog my textual library
on that personal computer -- _value added_ that helps justify the
purchase expense.

Once again, IMO an 'Apollo style' Mars mission makes the mission
riskier but less costly. I assume some common sense is included
in the implementation decisionmaking process.
Cost versus risk is a standard trade in systems engineering.
Cost versus benefits achieved also is a standard trade in
systems engineering.

I discussed the option of assembling and launching the
Mars mission in/from Earth orbit. There also is the
option that the Mars mission final destination once again
is achieving Earth orbit -- no Earth/lunar touchdown. These
options offer potential fuel volume savings (less wasted
mission volume and mass), and IMO the inorbit infrastructure
used for inorbit assembly and retrieval might have
greater _value added_ (re)use.

Indeed. But with cross-posting instead of multi-posting, you wouldn't
have seen the 2nd msg (whichever one it was) because your software would
have noted that it was part of a cross-posted set and marked the 2nd msg
as already read. You see now how this can work for you?

Okay, but if that's the case, then you're asking mission backers to accept
a higher risk. As I mentioned, backers don't like risks. In the trade,
it's called a 'negative' selling point.

That's well worth hoping for, yes. <g>
Seriously, a lot of funding is done on a whim. Provided that the
presentation team have laid out their plan well and emphasised the
positive aspects, it probably doesn't matter very much what the price is.
Ater all, in the eyes of the backers, this is pretty much a one-off
project, so they don't really care about the extra cost in building a
bigger craft if it looks as if it's going to be a success and going to be
seen to be bringing in 'positive returns'[1]
Let's see. You're a well-read chap, aren't you? Do you remember C.
Northcoate Parkinson's book _Parkinson's Law or The Pursuit of Progress_?
Well... the chapter on 'High Finance' is instructive.[2]

That's very true. But it may not be the downside that it initally seems.
-----Footnote2-----
1. Positive return need not be financial. Goodwill, prestige, etc are all
positive returns in the eyes of fianncial backers.
2. For the benefit of those for whom it may have been some time since they
last read the book, Parkinson points out that the amount of time
committees spend on discussing and *approving* projects costing 10,000,000
(for eg, a new nuclear-powered power station) is less than that spent on
discussing projects costing a few 100's (say, a bicycle shed outside the
power-station) and *substantially* less than that discussing the few 10's
spent on provision of coffee and cakes at the company's annual welfare
meeting.

As I mentioned in a different message, system engineers
enumerate and quantify -- system engineers seldom make
implementation decisions.
That does not mean that system engineers' lives are without
conflict. I can imagine situations where a supervising manager
prematurely visits a system engineer and says "This is the
decision -- justify the decision in writing and sign it."
"... crew-members who can't learn to function properly ..."?
I've never been a crew member, but I am a small businessman.
If a businessperson continually finds him/herself out of their
depth, IMO they are in the wrong business and should change
business lines.

IMO the combination of an (unprecedented) permanent petroleum
shortage that increases business and living costs across the
board, combined with increased overhead due to (nonproductive)
security expenditures, plus long term loss of jobs in the
United States domestic (and European?) economies is changing
the rules permanently. I believe that Government pursestrings
will tighten, and I would not count on 'funding on a whim' for
science projects while there are domestic food, shelter and
energy needs that are _not_ being met. In addition, the
demographics of the 1950's Baby Boom are loading (and will
continue to load) Social Security and Medicare heavily throughout
the next decade -- an expensive financial burden.
Don't get me wrong -- I _like_ pure/applied science and the
potential benefits it brings. But there are only so many
resources and prioritization is _mandatory_.
For example, we are running out of petroleum, and we won't
create more. [My _not_ informed opinion is that a significant
amount of Saudi Arabia's immense oil reserves have been
expended. I do _not_ know how heavily we depleted Iran's
oil reserves during the Shah's rule. I know that Oklahoma
(which once had formidible oil reserves) contributes little
petroleum today. The expense and complexity of deep water
petroleum drilling operations boggles my mind. And the
cost and logistics of developing new South American and
African oil fields and getting the product to the ocean
for shipment are staggering.]
During the Carter Administration we tapped the Strategic
Petroleum Reserve (SPR) to keep the wheels turning domestically.
During the Reagan Administration we put refilling the SPR
'off budget' to obscure the cost of the refill. I do _not_
know how the SPR and its maintenance is handled by President
George W. Bush's Administration, but I know that the SPR
currently is being refilled and that this cost is a campaign
issue. I also know that adding excise taxes to gasoline
(an issue where I have mixed emotions due to excessive
regressive taxation penalties to lower income and rural
populations) is a Presidential campaign issue.
How/when do we fund research for practical affordable
alternate energy sources? To my knowledge this research
effectively ceased after former President Carter's administration.
And to size the funding scope, let me address one issue:
safe nuclear waste storage. In a very reputable engineering
periodical I read that we have studied this problem for twenty
years without coming to an optimal conclusion. ****I also read
that before we complete constructing safe nuclear waste
storage facilities, we will have spent one thousand dollars
for _each household_ in the United States.**** If implemented
that thousand dollars will sit atop your electric bill, Brian.
Alternative energy is a fundamental and crippling problem.
If the lights are out on the ground, the USS Enterprise
ain't goin' nowhere.
Mandatory prioritization eliminates 'funding on a whim', Brian.

Brian, one of my former supervisors had a favorite saying:
"The nice thing about hitting your forehead against the wall
is it feels so good when you stop." I never commented,
but everytime my former supervisor repeated that maxim
I thought "The nice thing about hitting your forehead against
the wall is it teaches you to find doors."

Recall that Apollo had a lunar orbiting 'mother ship'
and a downsized 'lunar lander'. Apollo did _not_ land
its entire mass in the Moon's gravity well.
If this strategy was followed in a Martian mission, you
would need at least two people -- one in orbit and one
for the Marswalk.
And as far as the Marswalk goes, in Red Cross lifesaving
they taught us 'the buddy system'. Having an itch you
can't reach because you left your backscratcher at home
is frustrating.
