Yes, Vernor Vinge makes these points most eloquently in _The Peace
War_ and especially in the sequel _Marooned in Real Time_.  He does
not posit strong AI, but powerful automation and some new physics
are the rule.

Don't want to give much away, but he also deals with the other side
of the vertical line; there is a description of what life is like
just short of "singularity".  Much entertaining speculation, and some
of the characters are riveting.

Now that I know a little about mirror-making, I'd like to hear again
how the Hubble mirror contractor messed up the figure of the main
mirror.  I understand it has spherical aberration, but wonder how
[Rockwell?] managed to do that.

Thanks for any info.

    Well  ,  it  sounds  like the willingness to cling to some kind of la-la
   land belief that our  government  wouldn't  lie  to  us  about  the  moon
   landings  won't  just  melt  in  the  face of straightforward ,elementary
   mathematics ,and piles of circumstantial evidence. I guess I'll just have
   to use even bigger piles of circumstantial evidence and MORE  math.  Here
   goes:

    In one sixth gravity , a 180 pound man would weigh  a  mere  30  pounds.

                                6/180 = 30

    Writers  had  programmed the public to expect spectacular athletic feats
   when astronauts explored the moon. In the November 1967 issue of  Science
   Digest  an article entitled "How to walk on the Moon " predicted that men
   would be able to make 14 foot slow motion leaps,  perform  backflips  and
   other  gymnastics  like  professionals.   and  be  able to easily move up
   ladders and poles with their arms . An astronaut, , even in a  cumbersome
   suit  could jump six times higher on the moon than on earth.  Even though
   the alleged weight of the spacesuits and backpacks was 185 pounds  ,  the
   total combined weight of a 185 pound astronaut and his suit would only be
   62  pounds  on the moon . This is still only one third of the astronaut's
   weight.  Therefore , they should have been able to jump far  higher  than
   they  could  on  the earth without any difficulty. The average person can
   jump about 18 inches vertically without a  run.   On  all  of  the  video
   footage  shot  by  the  astronauts  while  in  the moonwalking mode , the
   highest leaps performed by the most vigorous individuals,  such  as  John
   Young,  never  amounted  to  more  than  about 18 inches, while they were
   THEORETICALLY CAPABLE OF SLOW BACKFLIPS!

    Another thing.  The practical design of a spacesuit would  dictate  that
   economy  of  weight  be  a  prime  consideration,  for  the  purposes  of
   maximizing  payloads.  The  value  of  185 pounds cannot be accounted for
   unless you attribute most of  this  weight  to  some  mysteriously  heavy
   equipment  in the the backpack. While a Scuba diver's dual tanks weigh in
   at about 80 pounds and are designed to aid the diver in  sinking  to  the
   bottom  ,  presumably  the  astronaut's  air  containment system would be
   significantly lighter. If we allow 40  pounds  for  air  containment,  20
   pounds  for  a  hefty  battery , and 40 or so pounds for lightweight heat
   pumps and the like ,that leaves 85 pounds for the suit itself .  This  is
   just  not  a  believable  figure  judging  from the general appearance of
   flexibilty of the material.

    If we merely assume that most of this alleged weight was taken up by the
   backpack and helmet assemblies , placing the center of gravity high above
   the astronaut's waist , the astronauts would have been a great deal  more
   "hunched over" to a near "V" position with helmet and backpack positioned
   equally distant from a center line drawn straight up from the toes , just
   to  be  able  to  maintain  their  balance.   Yet a "lean" effect is just
   slightly noticeable in a photograph of one of the astronauts  saluting  a
   flag  planted  on  the  moon.In  the photograph,the angle of lean is more
   consistent with a backpack weighing about 45 to 65  pounds  .   I  invite
   interested  science  oriented individuals to research this conclusion for
   themselves.

    During Apollo 17 ,  astronauts  Cernan  and  Scmitt  began  their  first
   assignment  by deploying and loading the Rover . Cernan apparently became
   quite excited and his Capsule Communicator , astronaut Parker warned  him
   that  his  metabolic rate was going up. That meant that he was using more
   oxygen. Cernan replied  that  he  never  felt  calmer  in  his  life  and
   indicated  to  Parker that he would take it easy . He mentioned to Parker
   that he thought that it was due to getting accustomed to handling himself
   in "zero g".

    Parker, an astronomer, then stated that he thought Cernan was working at
   1/6 gravity. Cernan's reply was "Yes. You know where we are....whatever."
   This remark suggests that Cernan wanted to avoid the discussion.  Perhaps
   Parker  was  not  aware  of  the  high  gravity  situation  and  asked an
   embarrassing question.

    Sorry to interrupt your net.reading.  I have searched FAQs for hours
now for references to plant growth experiments in different gravitational
environments and have found nothing.

    I am looking for papers, ftp sites, abstracts, or reference materials
on plant growth in different gravity conditions.  Pointers to papers,
references, etc. from NASA plant growth experiments in zero gravity or work
done on plant growth in gravitationally chaotic environments (constant
tumbling?) would be much appreciated.  Any other related references are
certainly welcome!

    Please e-mail me at [e-mail] as I am not a regular reader
of these newsgroups.  I will summarize the information for anyone who may be
interested.

    There's a good article in the latest Av. Week about this.
Yes, they will try to market the RD-170/171.  I don't have the mag
with me right now, but P&W will be the sole rep. for Energomash in
North America (I think).  The time scale for actual engine
availability was undefined (depending on the application, I'm sure).

    Av. Week had a second article on the NPO RD-701, a tri-fuel
engined which burns kerosene, LOX, and LH2, with continuously variable
fuel transition from kerosene to LH2.  Is this to customize the rocket
performance as a function of altitude, load, etc.?  The thrust figures
for all kerosene were significantly higher than with pure LH2.

The subject is covered in _Space News_.  While they don't specifically say that
the RD-170 will be available, they do say that P&W will be marketing the Russian
hardware, and they mention the RD-170 as "the engine that everyone in the world
would like to get his hands on."  Apparently P&W sees this as very useful for
their NLS work.

The article mentions the RD-701 which uses kerosene, LOX and hydrogen.  I assume
this is a cryogenic engine.  I believe that the Russians recently started
operating a cryogenic engine somewhere, so it would be a good bet the Energomash
has one already built.

Surveyor 3 was the one that Apollo 12 collected souvenirs from. :-)
Surveyor 2 wasn't suitable for this purpose, having crashed after a
failure in one of its vernier engines sent it tumbling out of control
during retrofire.

The other failure of the 7-mission program, incidentally, was Surveyor 4.
It abruptly went silent, quite mysteriously, shortly before landing.  If
this was a transmitter failure and not something more fundamental, it may
actually have landed safely.

If I remember correctly, the Moon Treaty declares the Moon (and maybe all
other celestial bodies) the inheritance of all mankind or something like
that - very similar to what they've done in Antarctica.  Meaning, no
companies can own land, and it's only to be used for scientific investigation.

Now as to enforcement, well, if you can get there in the next 5 years, I think
you'd have a few years _at least_ before any government could even get
anything there.  Think if you tried to set up a factory in Antarctica.  YOu'd
get kicked off pretty quick, and taken before some international court, all
by an international military force.  This would be harder to do on the Moon,
but if you had any sort of requirements from Earth, they'd starve you out to
get you to come back.  If they did get up there, though, they'd probably
bring enough force (eventually) to kick you off.

There is one point though:  I don't think the U.S. ever signed the Moon Treaty.
I'm not sure, however.  I also could have mis-stated what the Treaty actually
says.  This is what I remember, however.

I've heard that the car in question is up for sale to the highest bidder.
It will probably end up in a museum.   Also, the meteorite has been sold.
I've talked to the individual who bought it - he wouldn't tell me how much
he bought it for.  The meteorite weighs 27 pounds and one side of the
meteorite has red paint on it from impact with the car.  The meteorite went
all the way through the car at a very high speed.

Yes, Monogram has a very nice 1/72 scale X-15A-2 which can be shortend into
the original X-15, if you wish. Also their was a vacuformed X-15 but
was not very accurate. Revell used to make a 1/64 scale X-15.
Also avialble is Monograms X-15 with B-52 mother ship(1/72 big), and a B-52
X-15 combo in 1/200 from DML, just out.
