Yes you are incorrect. According to a friend of mine at the Reston Program
Office they will be using hudrazine thrusters. BTW, these thrusters are the
single heviest items to be returned to Earth. They must be returned intact
since it would be too dangerous to re-fuel them in orbit.

Spacelab is an experiment carrier. It will tell us nothing about
building large scale structures in space and cannot be considered a
station precursor.

NASA is buying launch services from COMET. NASA woldn't have been able
to build the COMET system itself.

Since you agree that the NASA program costs a lot more money, why don't
you thing we would be better off with the cheaper program of throw away
hardware?

Buying launch services at three times the price the private sector
pays cannot be considered 'minimal cost'.

I would rather get the bus out of the station first and then worry about
the experiments.

>See there NASA ain't half as dumb as the average poster to sci.space.

Dennis, The Wake Shield facility would cost NASA $93 million to build
(according to their cost model). A private company is building it for
$11 million. Spacehab would have costed NASA $1.1 billion (again,
with their costing model). A private company is doing it for $153
million. NASA would have taken eight years and $1 billion to build
the same DCX vehicle which McD is building in two years for $60 million.

Apply those ratios to your everyday life. Would you pay $20 for a
Whopper from Burger King? NASA would. Would you pay $100,000 for
a Ford Escort? NASA would.

Do you consider this intelligent behivior?

We have Dennis. We have.

Absolutely. But they are overshadowed by the bad things and will continue
to be as long as people ignore the problems.
