- I *knew* that my assertion would catch your attention.
-
- The Space Shuttle is the most expensive launch vehicle (per pound in orbit)
- that exists today. I believe this, but cannot prove it.
-
- The "official" NASA budget line item for the shuttle operation does not
- include all shuttle-related expenses. During the 1990 authorization process,
- Richard Truly was asked how much of NASA's budget went towards the shuttle -
- his response was "about two thirds". Since NASA's budget then was about $14
- million, it isn't hard to imagine shuttle launches at over $1 billion a pop.
-
- Using a 50,000 lb. payload for the Shuttle to calculate its cost per pound
- does not take into consideration the trivial fact that the Shuttle never
- carries 50,000 lbs into orbit. Maximum payload weight for a safe abort is
- 40,000 lbs, and the shuttle rarely carries that much weight.
-
- Finally, all of these figures ignore the development and construction costs of
- the shuttles. Figure those in, and you get an average launch cost of $1.67
- billion per pop.
-
- I'm sure that Pegasus' launch costs are much lower than the Shuttle's all
- things considered.
-
- However, I freely that I hold this opinion largely on the basis of a gut
- feeling, rather than the available numbers.
