CLINTON/GORE ON AMERICA'S SPACE PROGRAM
The end of the Cold War offers new opportunities
and new challenges for our civilian space program.
In recent years the program has lacked vision and
leadership. Because the Reagan and Bush
administrations have failed to establish priorities
and to match program needs with available
resources, the National Aeronautics and Space
Administration (NASA) has been saddled with more
missions than it can successfully accomplish.
Bill Clinton and Al Gore support a strong U.S.
civilian space program -- for its scientific value,
its economic and environmental benefits, its role
in building new partnerships with other countries,
and its inspiration of our nations youth. A
Clinton/Gore Administration space program will seek
to meet the needs of the United States and other
nations while moving toward our long-term space
objectives, including human exploration of the
solar system. A Clinton/Gore space program will
also promote the development of new technologies,
create new jobs for our highly-skilled former
defense workers, and increase our understanding of
the planet and its delicate environmental balance.
Move beyond the Cold War
* Restore the historical funding equilibrium
between NASA and the Defense Departments space
program. The Reagan and Bush Administrations
spent more on defense space initiatives than
on civilian space projects.
* Achieve greater cooperation in space with our
traditional allies in Europe and Japan, as
well as with Russia. Greater U.S.-Russian
cooperation in space will benefit both
countries, combining the vast knowledge and
resources both countries have gathered since
the launch of Sputnik in 1957.
Improve the American economy through space
* Direct NASA to give high priority to continued
improvement of the American civil aircraft
industry, which faces increasing international
competition. NASA research can play an
important role in developing less polluting,
more fuel efficient, and quieter aircraft.
* Work to improve our space industries
competitiveness. Well direct NASA to develop
cutting-edge rocket and satellite
technologies. We will also develop a new,
cost effective, and reliable launch system to
maximize scientific and commercial payloads.
Link NASA and the environment
* Support NASA efforts -- like Mission to Planet
Earth -- to improve our understanding of the
global environment.
* Call on NASA to develop smaller, more focused
missions which address pressing environmental
concerns.
Strengthen NASA and education
* Direct NASA to expand educational programs
that improve American performance in math and
science. Space education can help maintain our
technological edge and improve our
competitiveness.
* Direct NASA to expand the outreach of its
educational efforts beyond its five field
centers, so that millions more people can
learn about space.
* Maintain the Space Shuttles integral role in
our civilian space program. The Shuttle is
extremely complex and will always be expensive
and difficult to operate. But we must take
full advantage of its unique capabilities.
* Support completion of Space Station Freedom,
basing its development on the twin principles
of greater cooperation and burden sharing with
our allies. By organizing effectively on this
project, we can pave the way for future joint
international ventures, both in space and on
Earth.
Encourage planetary exploration through the best
space science
* Stress efforts to learn about other planets.
These improve our understanding of our own
world and stimulate advances in computers,
sensors, image processing and communications.
* Fully utilize robotic missions to learn more
about the universe.
* Although we cannot yet commit major resources
to human planetary exploration, this dream
should be among the considerations that guide
our science and engineering. Because the
entire world will share the benefits of human
planetary explorations, the costs for any such
projects should be borne by other nations as
well as the United States.
The Record
* Senator Al Gore chairs the Senate Subcommittee
on Science, Technology, and Space, which has
primary responsibility for NASA and plays a
key role in efforts to strengthen and
revitalize America's space program.
* Strongly favors a balanced manned and unmanned
space program. Supports completion of Space
Station Freedom and enhancements to the fleet
of Space Shuttles to ensure safety and
reliability.
* Has championed Mission to Planet Earth, an
initiative designed to gather comprehensive
information on the Earth's changing
environment. He strongly supports efforts to
channel information on the Earth's environment
to teachers and school children.
* Strongly supports efforts to strengthen our
leadership in aviation.
* Has tried to use space exploration as a bridge
to international cooperation, not competition.
Pushed the administration to investigate the
possibilities for integrating surviving
elements of the Soviet space program into the
U.S. program in ways beneficial to America and
its aerospace workers.
* Following the Challenger disaster, Senator
Gore uncovered quality assurance deficiencies
at NASA, gaining a greater commitment to
quality assurance and accountability at NASA.

And remember that the current day cellular radio telephones are only feasible
because of the military R&D in semiconductor electronics: without the
current day VLSI CMOS chips, the cellular telephone (car phone) would
require a semi-trailer to hold the electronics and most of the engine's
output to power it.
911 telephone service, automated dialing, caller id, and a host of other
micro-electronic devices would also not exist if it were not for
military R&D spending.
Oh yeah, we also get a whole *lot* of our fancy medical gadgets
from military R&D offshoots.
Entitlements and foreign aid are examples of gov't expenditures which
are not "economically beneficial." Foreign aid devalues the dollar.
Entitlements prevent people from contributing to the economy.
Military R&D provides jobs (Damn good paying jobs) not only for
those who do the work, but also for a great deal more who make
the supplies for the work.

So what about the benefits from just plain space exploration? Imagine the
spinoffs once we get a space platform working, or get a colony on the moon?
Or for that matter, make it to the moon again. The benfits of this
could be huge. At the same time, people are getting employed and less
money is going to trying to kill someone else.

It looks to me that Tom is coming across as a Utilitarian, whereas I (and
maybe yourself from the above statement) would fall into more of a Natural
Rights paradeigm.
Utilitarianism makes interesting arguments, but it can justify some truly
awful things. One can justify leibensraum with little trouble, because a
simple regression of the ongoing argument makes "our race" better than "their
race" because I am a member of "our race", and anything that improves
conditions for "us" is therefore good. If you push on it at all, it basically
breaks down into the "Might makes right" school.

Again, you're ignoring something. I eat to survive. Someday, something might
eat me to survive. There's a fundamental difference between survival needs
and non-survival needs.
We humans don't need to terraform Mars to survive. THAT is the crucial
difference which you're ignoring.

I'm trying very hard to not flame you, believe me. Again, you're missing a
crucial difference.
1) The right to defend onesself from attack (be it disease or a foreign
country)
cannot be denied.
2) Terraforming Mars IS NOT REQUIRED FOR THE SURVIVAL OF THE HUMAN
SPECIES!!! Can't you get that through your skull?? _IF_ it were I'd
agree with
you. It isn't necessary for us to survive.
And again, should it prove that there is no life there, then let's go
great guns,
after we understand everything about Mars in its natural state.
Survival imperatives are different from voluntary imperatives. If terraforming
Mars were a survival imperative, then I'd agree that we should destroy the
(hypothetical) life there. After we understand as much as we can about it.
However, as I said before, but it bears repeating: TERRAFORMING MARS IS
NOT A SURVIVAL IMPERATIVE!

If it wasn't in that particular message it was in this string that
you cannot, repeat cannot, show any self interest in terms of
survival by terraforming Mars. Unless you can there is no case that
you can argue that I am ignoring my own self interest. This argument is
getting stupid. You are just writing in debating style. I don't wish to

How do you know what is sentient and what isn't? On the one hand you claim
that you aren't omnipotent, then on the other you make statements that
seem to say you are. Man has never gotten a decent definition of sentience
and yet you know what it is.

I spent 3 years working at a facility that handled HIV on a research basis.
Since it was possible to become infected I made every effort to

Sure. Basically all the world's industrial nations *did* have the same
kind of environmental management as the former Soviet Union until about
1970. About the only difference between the US and the SU until then was
that in the US someone could sue if guck leaked onto his property. There
was no legal basis for bringing action for leaks on someone else's
property until the various environmental laws were passed in the 70s.
You have no idea what the water looked like or smelled like downstream
of a textile mill. You have no idea, until you visit Copper Hill Tenn
what a copper smelter can do to the vegetation of an area. You have
no idea what a coal tailings pile weeped. Only 20 years ago these things
were as common in the US as they are now in the ex-USSR. How could
things have been this bad only 20 years ago? You have no idea how
*big* this country is. Most people never saw these things and those
that lived amongst it earned their *living* producing the messes.
Environmental disasters aren't new. The Great Sahara *Forest* was

Just what is your source for this information??? Experimental sensors???
I've heard of nothing experimental about the instruments proposed. If
they are able to make them as lightweight as they hope to, they would
different from previous instruments in this way, but hardly what I would
call experimental. And you make it sound like the mission designers are
going out of their way to AVOID using ion drive. Nonsense! The launch
vehicle hasn't even been selected yet, nor would I expect them to unless
the mission actually gets funded. Atlas-Centaur, Titan IV, and Proton
have all been suggested as launch vehicles at different times during the
mission planning, with the preferred vehicle depending on the tradeoff
between spacecraft mass and flight time. Just exactly what "never-before-
at-that-scale solid rockets" are you referring to?

Define Planet X and I'll tell you whether it is or isn't. If size is your

In that pool, if you add a dye, you will notice convection currents driven
by the temperature gradient induced by the sunlight.
I still do not understand why a person would posit that the surface or
atmosphere of Pluto would be isothermal. Isothermal to within, perhaps
.5 K, but even a differential of .5 K is enough to drive some convective
processes.
What am I missing? Am I misinterpreting something?

None under the current system. With strong property rights it would not be
just a civil matter, but one of criminal theft and trespass. The cost of
suits is an artifice of byzantine legal structures that attempt to allocate
a resource without actually setting down ownership and a clear definition of
that ownership. When the law is ambiguous, the guy with the best lawyers
wins.

Again, the problem is that DOD is part of the government. The government
gives favor and the government taketh away favor. There is no defense for

If my frequency is my property, as clearly defined as the surveyor lines
that define my backyard, then it is just as easy to define that a crime has
occured in either case. Big guy or little guy, I need only show a title and
prove trespass.
An aside: there was a guy in England a couple years ago who defended himself
against a local authority that was going to bulldoze his house. He refused
to leave the property, and it was such a big deal that the BBC had a camera
when the dozer and a bureaucrat came down. The property owner shot the
bureaucrat, on camera. Most refreshing piece of news I've seen in years :-)
The Lib International should give him a medal, if they could get it to him
in prison...

Over dinner last night, a friend wondered if satellites had air in them.
If they do and are airtight, they must be built to withstand the
pressure in space. If they are evacuated, they must withstand the
pressure on earth.
Since I assume they are built in a room at standard pressure,
do they have pressure relief valves for when they get into orbit
(or is that onto orbit?) or are they built to withstand the pressure?
Thanks for any answers.

I used the word pressure 6 times in this post.

The rate actually depends on the solar cycle also: For some reason
cosmic rays are less intense during the solar maximum.
The rate is ~50 REM/year (1/week) at solar minimum and down to
~20 REM/year at solar maximum. There are some ideas out of Martian
Marietta for 1 tonne/_person_ shielding that would half this.

Anyone know if they took still pictures, as well as video,
of the frog experiment? Those frogs would make some handsome prints.
