There's a South Park episode lurking in there somewhere.
(Cut to image of Kenny impaled on a solar array.) :-D

Pat


There is an episode were the children are standing at the bus stop before
school and MIR falls on Kenny.

"Oh, my God, MIR killed Kenny! You *******s!"



Found a link to a picture.

NASA does appear to be at a decision point here. If we go ahead with the
CEV, stick, and SDHLV, it's insuring that NASA will continue with its
business as usual approach to manned spaceflight.


...You are, as usual, ignoring the *real* reason that we should build
our own boosters instead of depending on ones built by foreign powers
and/or corporations: what guarantee is there that they'll always be
there and/or will be cooperative when some other geopolitical fiasco
occurs?


I'm referring to Atlas V and Delta IV. If they're good enough to launch
multi billion dollar US spysats, they're good enough for the CEV.

I'm not suggesting we buy launches from Europe or the Russians. As Henry
likes to point out, NASA typically doesn't like its buget to be spent
overseas. It prefers to get everything "international" it can by barter.

Having a bunch of such cars on the road would have a bit of an exhaust
problem: imagine the stream of condensed water they'd leave on a hot,
humid day. The low efficiency means the heat exchanger would have to
pull a lot of ambient air, and that moisture can't be allowed to
freeze on the heat exhanger.

It has possibilities, but the motor efficiency needs a lot
of improvement and the thermodynamics are inherantly lousy.


Okay....but other than those slight problems.... :-)
Now, when I do build my vehicle powered by this system, I intend to put
the heat exchangers inside of flapping wings that will fold up along the
sides of the vehicle's body when not in use. Since this propulsion
system is independent of outside air this vehicle will also be able to
operate underwater as a submarine, powered by propellors at the stern.
Once it flaps itself skyward like an immense bird from my secret
mountain lair, these propellors shall also drive it forward in flight.
And what shall I do with such a combination car/boat/submarine/aircraft
terror?
First, I shall revenge myself upon the members of the Weldon Club of
Philadelphia for their treacherous destruction of the "Albatross".
Then I shall challenge Supercar to an aerial/surface/underwater duel to
determine who shall be The Master Of The World, and who shall be the
mere puppets of The Master Of The World. :-D

I still picture that mirror out of Hubble coming out of the sky like a

Yes.

Returned how? The CEV isn't big enough to return an SSME.


And whoever said use the CEV for that role? Again, *think.* Try to come
up with an approach. Think about it from the standpoint of the
entepreneur.


An entrepreneur? Where is there any place for entrepreneurs in the
glorious new Vision of Socialist Exploration? NASA refused to even buy
its launches commercially -- something it is *required by law* to do
whenever possible -- so what makes you think unqualified scum like
entrepreneurs will be allowed anywhere near this precious hardware?

There are, say, a dozen SSME's on orbit...


No, there are, say, a dozen SSME's in fragments on the Pacific floor.
NASA isn't going to leave them in orbit until there is definitely
something that can be done with them. There's no justification for the
effort of cutting them loose from the stage unless salvage is going to
happen, and just storing the stages has most of the problems of storing
External Tanks -- you have to get them up to somewhere like the station
(whereas they're normally abandoned at lower altitude), you have to make
them compatible with long-term storage, you have to worry about drag
issues -- and there's no way NASA is going to make the effort without a
reason. If they couldn't be bothered doing it for the ET, they won't do
it for this hardware either.

...How would *you* go about getting 'em?


Not possible. (Technologically, yes. Politically, no.) It has to be
a billion-dollar BoeLock project or it won't happen. No reason for me to
bother even considering it.

...But here's the
difference: the Stick Stage 2 will end up in some sort of orbit.


And will then be de-orbited, probably the same way the S-IVB stages of the
Skylab crews were de-orbited -- by propellant dump through the engine.
NASA is terrified of leaving things in orbit that might fall on somebody
and result in lawsuits, or even just increase the debris problem. They
already set the precedent with the ET: no spent hardware left in orbit
unless someone has specific, credible, NASA-endorsed plans to do something
with it, including triple-redundant precautions against unintended reentry.
(I'm not kidding about the triple redundancy.)

Also, almost certainly the second stage's orbit is going to be very low,
because you want to shed its dry mass as soon as you don't need all that
thrust. NASA will quite legitimately refuse to accept the payload penalty
of putting it in a higher orbit just to facilitate hypothetical future
salvage operations.

...talk (calmly) to your
Congresscritters and get them to order NASA to either use the stages on
orbit, or have them transfer ownership to the highest bidder...


NASA's answer will be: "we have no plans to use them in orbit, and there
is no *qualified* bidder who we recognize as competent to take them over,
so we regretfully must continue to de-orbit them; we'll be delighted to
start transferring ownership as soon as there's a qualified user for them,
hee hee".

People have been through this before, Scott, and there is no reason to
expect that the results would be better this time. "Fool me once, shame
on you; fool me twice, shame on me."

Under (early) Goldin, odd though it might sound, there actually was some
small chance that such a radical proposal might get somewhere. Under
Griffin, looks like there's no way -- reform is not on his agenda.

Somebody should look into vehicles powered by compressed gas boiled off
of liquid air.


People have looked at LN2-powered vehicles. (You don't want to use liquid
air -- it turns itself into LOX as it boils, roughly speaking, and then
you've got a nasty fire hazard.) They're not competitive with gasoline
vehicles. They probably *could* be competitive with current electric
designs, and maybe even with current hydrogen designs, but they're out
of fashion politically and there is little funding to be had.

If LOX is that cheap, simple liquefied air should be dirt cheap, and the
emissions would be non-polluting.


It is (cheaper, in fact), and it is (LN2 is only slightly more expensive),
and they are.
