I must agree with Mark S.' assessment of the situation, as must any reas-
oning person. The percentage of materiel being lifted into orbit that is
of a military nature is increasing logarithmically. The u.s. "space program"
has been completely militarized (the desired outcome of the Challenger affair),
and with deployment of SDI weapons systems on the way, I don't really see
any sort of improvement in life on Earth, unless you call the very REAL threat
of nuclear death from the sky replacing the UNLIKELY POSSIBILITY of nuclear
death from the ground an improvement.

We are as far from being able to mine the asteroid belt as we are from
finding Oz at the end of the yellow brick road. They are both farfetched
fantasies. The space program of lunar exploration followed by Mars ex-
ploration that would have led to our eventual mastery of space travel
has been replaced by the "space program" that explores new and better
ways of launching new and better weapons systems into orbit around the
Earth, that will eventually lead to confrontation and nuclear-armed
conflict in space. There are no benefits for mankind to be derived from
this course of action, unless you loosen the definition of mankind to
include the profiteering weapons-builders who derive their vast incomes
from producing horrifying devices to kill humans on a massive scale.
They, as always in our "society," will benefit.

Before we can capture and mine asteroids for metals, and build "space colonies,"
we must learn to keep men alive and HEALTHY in space for more than seven days at
a time, must develop REAL spacecraft that are not just bullets with men in their
noses, develop human psyches that will not become deranged by close confinement
with other humans for more than 30 days at a time, develop equipment that can
do more in space than just open its doors and pop weapons satellites into orbit,
and develop the intellectual advancement necessary to produce a world whose
population cooperates for the mutual good of mankind and the planet Earth, in-
stead of a planet of warring nations still fighting each other over moronic
thousand-year-old territorial claims, and finally a world population that
recognizes that organized religion is a racket from which thousands profited
for nearly two thousand years, while BILLIONS HAVE DIED. And all of this develop-
ment shouldn't take more than another two or three thousand years. Now, con-
sidering that at our present rate of destruction of the planet Earth, we have
perhaps between 50 and 100 years left to exist, well..., you get the idea.

THE main problem with the u.s. "space program" is that everyone is being
fooled by this misnomer. It should immediately be corrected to the far
more truthful, "orbital weapons deployment program." Then everyone can stop
pipe-dreaming about colonizing space, and concentrate on being scared
s**tless of nuclear death from the skies.

Football, baseball, basketball, soccer, hockey, tennis, wrestling, boxing,
lacrosse, and gladiatoring are all CHEAPER than conquering space, and in
fact are the DIRECT CAUSE of the u.s.' failure to do so. So, batter up...

It seems to me that if you dropped "clouds" of blue-green algae into
the Venusian atmosphere, the poor little algae would be carbonized by
contact with the H2SO4, and "clouds" of carbon particles would drift
down into the blast furnace to be incinerated into something or other
that wouldn't do anybody any good.

If there was any O2 in the Venusian "atmosphere" it would react quite
nicely, and violently explosively I might add, with any and all metal
and mineral substances available as a serendipitous result of the
900+degree F temperature. So if we did figure out some way to create
large quantities of O2 in the Venusian "atmosphere," Venus would indeed
make a spectacular "morning star." I think the effort should be planned
to take place on July 4, or July 14, or May 1, or some other appro-
priate date.

If you could guarantee the good ol' boys that 200,000 fans would show up
for the kickoff, and they could get the TV rights for the next millenium,
the bucks would be on the table so fast that your mind would boggle.

Or do like Amerigo Vespucci - write a letter describing someone else's

 The problem with moving Venus to the Lagrange point 180 degrees around
the Earth's orbit is that that L point is not stable, and perturbations
from it get larger, not smaller. The problem with sticking Venus at either
the L4 or L5 point in the Earth-Sun system [God, I'm saying this badly]
is that I belive those points are only stable if the third member of
the triplet is much less massive than the other two. Having Venus in an
unstable orbit around Sol at roughly 1 AU would make me nervous. Of
course, a collision between Venus and Earth would solve the excess
atmosphere problem [And if we can move worlds, we should be able to
maintain their new orbits artificially. "Daddy, where did the crystal
sphere of heaven come from?" :) ].

I don't know what "prebreathing" refers to, or why it is necessary.  Could
someone explain this?  Thanks in advance.

Last night, the Hubble Space Telescope controllers successfully
completed a test of the pointing and control system and fine
guidance sensors.  First indications are the systems are working
properly and as they are now able to find and lock onto specific
guide stars.  The first pictures are possible within the week.

Controllers were also successful in reducing the plus or minus
three arc-second roll oscillation to at least in half.  And, they
are optimistic that further analysis of the data will provide the
information to resolve the oscillation problem completely.  That
means controllers can now proceed with the first in the long
process of steps to focus and align the two telescope mirrors.

Kennedy Space Center ground crews at Pad 39-A are removing the
floor panels from beneath the Columbia payload bay.  Preparations
are underway to access the coolant loop valve.  Also, to
depressurize and drain the system of Freon.  For protection, a
debris shield has been placed over the payload and handling
equipment.  The launch date will be determined next week.

UPI says a report prepared at the request of the Senate and

released today.  It said a variety of options are under
consideration to meet increased needs created by new initiatives
to build a space station, returning to the moon and exploring
Mars.  Committee Chairman Rep. Robert Roe said, "we should take
the high road...and eventually begin to use these new frontiers
for scientific and economic gain."

Scientists report completing feasibility studies on producing
iron from lunar ilmenite.  The Space Studies Institute says
researchers conclude that iron could be extracted with a process
that uses hydrogen to remove oxygen from the minerals.  And, the
resulting iron "could provide the building blocks" for future
space structures.
