    The ideas below are my own, maybe right-maybe wrong, but thier a
    start:

    Well well, someone has seen the light, but Bob, we cannot help our
    companies, no matter what.  The U.S. has put thier foot in thier own
    mouth.  We believe in fair trading practices, and of course so do Japan
    and Europe (that's why they subsidize their companies).  As long as
    the U.S. stands by the Free Trade ideals (which I for one believe the
    idea is sound, as long as everyone plays by the same rules) then, we
    cannot protect our country, or companies from  onslaught of foreign
    competition that is unfair.  We cannot impose such laws that force
    the U.S. into protectionism, and we should not.  We should at all costs
    refrain from such protectionism.  Why, because that is what Japan and
    Europe want from us.  If we protect our markets, then why should the
    Japanese open thier rice markets, or Europe their Agricultural markets,
    in fact why sould any nation open their markets?  We will simply become
    like them, fall into thier own fallicies, and everything will become
    worse than it is now (for us and them).

    No, the U.S. is a symbol to the world on radical ideas and standards,
    we need to start to educated our children, teach them about this unfair
    world trade system, teach them to stand by the ideas of free trade, they
    are our future and the only hope of America's survival.  The way to beat
    the Japanese and the Europeans at thier game, starts in our homes and
    schools, not with the already, defunct U.S. government.  They have sold
    us out to line thier pockets with filthy gold.  It will take several
    generations, but if every good American was to start today it could be
    accomplished in our life times.  It is our choice.

Of course, this tremendous price does not take into account the other
costs of flying from PDX to Heathrow.  What about the food, and paying
the people to fly the plane?  Your point is taken, but I feel that $0.10
for a round-trip ticket will never happen.  (Or is this what you meant?)

Intelsat and Inmarsat are "mutual cooperation" type organizations.
They award contracts to participating countries in proportion
to the contributions each country makes to the consortium.
Each country gets back more or less what it puts in.
  RFPS ARE competitive, but contracts are not normally awarded
to a single company, rather to one of several competing
international consortia.
   Government ownershipof European aerospace companies has not
really improved their fundamental international competitiveness.
The lion's share of straight commercial space contracts goes to US
companies.
  On the other hand, the US launch vehicle market, the biggest in
the world is protected.   Foreign companies are not allowed to
launch US government satellites.   On the other hand, foreign
governments do use US launchers......Arianespace complains
that the US is engaging in unfair protectionism....

I had a question about space-suits and am sure someone can halp me with
I wanted to know what are typical values of losses of internal environment
from suits during EVA, and second, what kind of a system is used for
dehumidification of this internal environment.

    Ok, 77 sats from the U.S., 100+ from Russia, and who knows how many
    more from Europe and Japan, not to mention what is up there now, and
    not to forget what will be up there when and if NASA decides it can
    build a space station.

    Is there enough space for all this JUNK....?  Who (or what country
    will manage this JUNK..?

    Just a thought in passing.

    According to Discover Mag. January 1991, it is so that total coverage
    of the world is possible.  It also says don't expect it to be oper.
    for at least 2 years after 1991.  Thats it from there.

    As for politics, well I do not think that either Japan or Europe is
    going to like this, and AT&T are going to go insane if it really works.
    I would say if this works, takes off as planned, then, Motorola will
    be on MITI's shopping list.  And most likly Motorola will be powerless
    to stop them.

The US doesNOT believe in fair open markets.   On the contrary.
The US government refuses to allow foreign companies to bid to
launch US government satellites.   Foreign governments, on the other
hand, make extensive use of US vehicles.

Subject: Information sources for frequent space questions (1 of n)


Many space activies center around large Government or International
Bureaucracies.  In this country that means NASA.  If you have basic
information requests: (e.g., general PR info, research grants, data,
limited tours, and ESPECIALLY SUMMER EMPLOYMENT (typically resumes
should be ready by Jan. 1), etc.), consider contacting the nearest
NASA Center to answer your questions.

EMail typically will not get you any where, computers are used by
investigators, not PR people.  The typical volume of mail per Center is
a multiple of 10,000 letters a day.  Seek the Public Information Office
at one of the below, this is their job:

NASA Headquarters (NASA HQ)
Washington DC 20546

NASA Ames Research Center (ARC)
Moffett Field, CA 94035

Not a NASA Center, but close enough:
Jet Propulsion Laboratory [JPL/CIT]
California Institute of Technology
4800 Oak Grove Dr.
Pasadena, CA 91109

There are other small facilities, but the above major Centers are set up
to handle public information requests.  They can send you tons of information.

Manager, Technology Utilization
Office, NASA Scientific and Technical Information Facility,
Post Office Box 8757, Baltimore, Maryland 21240.

Specific requests for software must go thru COSMIC at the Univ. of Georgia,
NASA's contracted software redistribution service.  You can reach them
at [e-mail].  If this gives you problems, tell me.

NOTE:  Foreign nationals requesting information must go through their
Embassies in Washington DC.  These are facilities of the US Government
and are regarded with some degree of economic sensitivity.
Centers cannot directly return information without high Center approval.
Allow at least 1 month for clearance.  This includes COSMIC.

Rats! And there I was, all ready to issue a stock offering. :-)

I guess that also rules out a chain of steel balls, each supported by
two cables, with the actual projectile at the other end of the chain. :-)
