Read a little *more* history Ed. The robber barons were after
the almighty dollar all right, but it was the government land
grants that went with the railroads that they were after. Alternating
one square mile blocks on either side of the tracks for the length
of the tracks. Most of the railroads went bust, but the men who
built the railroads didn't care, they made their money developing
the real estate Uncle Sam gave them.

Because the alternative is no space station for zero dollars. While a
cost-efficient space station would be far superior to an overpriced one,
an overpriced one is far superior to no station at all and having the money
transferred to some rathole like HUD.

It didn't fly again because of technical reasons; the astronauts refused to
fly it. Incidentally, they are planning on flying it again and rendezvousing
with Mir, and possibly flying it back with a crew.
Hermes is still on, although another poster from Europe is of the opinion that
it is dead anyway...we'll have to see on that. Japan has limited shuttle
plans, first as an unmanned flier and possibly later a manned vehicle.

Well, let's look at some history, shall we?
First there was the Apollo pad fire, with three fatalities. The result?
The program was delayed, modifications were made, and the show went on.
Then there was the Apollo 13 affair...three people nearly lost in space, made
it back by the skin of their teeth. The result? The program was delayed,
modifications made, and the show went on.
Then, of course, came Challenger. Seven dead, $1 billion vehicle destroyed.
The result? The program was delayed, modifications made, and the show went
on.
I realize that all I have to back me up is a quarter-century of history of
U.S. manned spaceflight, but do you think it is possible that the likely
result of another accident is to delay the program and fix the problem,
instead of throwing up our hands in despair and cancelling it?

Well, history backs me up. What are you basing your assumptions on, other

Mir could sort of be considered as as point B, although I doubt the Russians

the equivalent of a research station on the northern tip of Greenland, with
about the same commercial potential.

Actually, that's incorrect. Ask Allen to explain the Kelley Act to you
sometime.
I agree, it's not quite the equivalent of what we have now, but air travel
didn't just pop up overnight; it was force-fed by the government.

Actually, operating tempratures and total stresses are also pretty close.
The main differences is in the turbopumps and those exist today. Peak
stresses on SSTO may be higher but Have Region answered most of the
open questions on that. That's why every agency and group which has
looked at SSTO say it can be done.
>And pigs would fly if they only had wings.
It would have been interesting to hear you in 1900 telling us all
about how heavier than air flight was impossible. I can just imagine
the flames about those two idiot bike builders who thought THEY
could do what all the experts said was impossible.

When you get the price of a space ticket down to that paid for
an E ticket by the rubes in the Winnebagos, we'll talk. Until
then, $10 million dollar rides into space are somewhat beyond
the reach of the unwashed masses. And it's too high a price to

trying to get work done.

It's a metaphor, stupid. We don't know how to make space profitable
because we don't know how to operate properly in space. Half the stuff
we try doesn't work, and the other half works in ways we don't completely
understand. It's also reality because, for example, we don't have a decent
gravity map of Luna, we don't have a mineralogical survey, or even know if
there is polar ice.

NASA plans to shut down Shuttle by 2005 in any case. It's not
Shuttle killing your grandiose dreams, it's the reality that
space is a hard place to reach and a difficult place to work.

Yes, but not a single one of them, nor every one of them combined
can get one inch above the atmosphere. Aircraft are *irrelevant*
to space. They can't get there. You might as well be talking about
steam locomotives.

Does some provision of international law allow this sort of declaration

As a wild guess it was probably done to prevent someone else
from going there and claiming it as salvage or abandoned

And some of them have been looking at it, as witness Hotol. They've
generally made the X-30 mistake of confusing hypersonics research with
practical spaceflight, so their designs have wings, but you *can* build
an SSTO that way.
Unfortunately, they've mostly got the same disease as NASA: any such
project would be a focal point of a space agency's efforts, not a low-
budget background experimental project, and hence cannot be allowed to
fail. This makes a never-before-tried concept less attractive than
just stacking up plain old rocket stages the old-fashioned way.

The capsule itself doesn't have to be disposable, but the rocket it rides up
on generally is. You're still losing 80 to 90 percent of your hardware each
flight.
Whether a shuttle is a step forward or not depends on what you are trying to
do in space. If your sole goal is to get people from the ground to an
already-existing space station, a capsule is probably the most cost-effective
form of transport, at the cost of having no other manned space capability. If
you are looking for a broader space capability, however, such as the ability
to fly numbers of non-pilots up, or to have station-independent research
capability, or to be able to deploy and retrieve large objects, then a shuttle
is indeed a step forward.

Do bear in mind, Matthew, that most of the projects you elsewhere described
as "shuttles" share the property of discarding most of their hardware.
Hermes, HOPE, and Buran all ride up on expendable boosters.
There are three separate questions here. One is semi-ballistic capsules
versus bricks-with-wings. Another is whether the spacecraft itself is
reusable. A third is whether the entire assembly that lifts off is
reusable, or nearly so.
Bricks-with-wings are really popular with people who associate them with
hypersonics research, but in fact they're not much better as a way of
getting people into space than semi-ballistic capsules. They are really
lousy gliders, can't abort a landing approach and try again, and are
much heavier than a well-designed capsule for the same payload. They
are also a lot harder to design.
Making the spacecraft itself reusable is no big deal. The Soviets have
reused capsules. About the only thing that really has to be replaced
on a semi-ballistic capsule is the ablative heatshield, if any. The
other refurbishing needed is a pale shadow of what the shuttle orbiters
need after every flight.
Making the entire assembly reusable is an important goal, but it's
self-deception to pretend that the shuttle achieves it, even ignoring
the external tank. The SRBs get rebuilt almost from scratch after
every flight; it is doubtful that NASA actually saves any money on
that process. The orbiters need months of concentrated maintenance
after every flight. "Salvageable" would be a better word than
"reusable" for this system.

With the sole exception of the Russians? With the sole exception
of the Russians, who else but the United States is putting people
into space?
Both the Russians and the United States are putting people into
space in artillery shells boosted by long-range missiles. Calling
the Space Shuttle a "space-transportation system" doesn't make it
one. Putting wings on a vehicle doesn't make it a space-transportation
system. A space-transportation system doesn't drop a major piece of
itself into the atmosphere to burn up. It doesn't drop boosters into
the ocean, where they can be fished out and refurbished at more than
the cost of replacing them. It doesn't require weeks of maintenance
before it can fly again or have to send its main engines back to the
factory for a complete rebuild after every flight.

Western ejection seats have long used powered chute ejection, actually.
Martin-Baker's latest seat can supposedly land you safely if you eject
from an upside-down aircraft 100 feet up, just by getting the chute out
damn fast. (It has its own altitude sensors, so it knows enough not to
do this at high altitude. If you eject inverted 100ft over Mount Everest,

I think the time the Shuttle's been flying is more like one year.
It's just been spread out over a 12-year period.
Does time in orbit really add up to a year?! That's a pretty
impressive duty cycle, even spread over five craft.
Factor out the Challenger moratorium and the inital ramp up
of launches and it looks even better. Not bad for a prototype...
Sanity check: O(50) missions at 1 week per - yup, that's a year...

Given that Martin Marietta was hesitating about entering the MLV-3
competition because of the lack of an operational Titan II pad at the
Cape, I would think that Clementine's going to have to go up from
Vandenberg. There were Titan II pads at the Cape once, as witness
the Gemini missions, but they're all decommissioned and rotting.
