- I don't think the Congress convened and said "NASA can't fly more
- than eight missions per year". Actually, the eight-per-year (seven
- on the slate for '94) is more of a 'let's not press our luck'
- decision than a 'can we justify more than eight a year' decision.
- NASA occassionally cites fuel costs as being involved, but that's
- hooey, IMHO. I think they are staring down that long dark one-
- failure-in-25-flights statistic and thinking 'let's not push
- the flight rate any more than we have to.' Wise decision, I'd say.
- If you ask me, they should fly Shuttle sparingly until Freedom is
- ready to launch, and then accelerate to 12 flights per year.
- That's one per month, a track record that they've demonstrated
- several times in the past few years, and are about to again, as you
- noted, from December '92 to April '93 (with only 3 Orbiters, BTW.)

- It basically comes down to a point of what one considers
- operational costs and what one considers related costs. On the
- operational side, counting Launch Control, OPF engineers, and
- fuel costs, Shuttle is still the most expensive. Of course, nothing
- else has to launch human beings, so comparisons are very tricky.
- On the related costs side of the budget, with the exception of the
- DC Revolution endlessly touted here on the net, new launch systems
- will still need major launch facilities (and standing armies), big
- computerized Mission Control Centers, and numerous contractors. These
- things are counted in Shuttle budgets, but not in Titan IV, NLS,
- or Spacelifter budgets. Of course then, the others look mighty
- cheap.
-
- I myself have given up the idea of comparison/contrast of launch
- vehicle costs, it's a Kobayashi Maru scenario if there ever was one.
- Instead, I'll let McDAC prove they can do it cheaper than Shuttle,
- since the DC-1 is the only thing on the drawing boards with similar
- objectives (sending up humans and payload and bringing them back.)
