- Of course, in addition to "Shuttle operating costs," there are
- ongoing Shuttle product-improvement/development costs. Eight
- flights per year is more than NASA's been able to manage most
- years. And you've conveniently ignored depreciation on the
- orbiter and the $32 billion in Shuttle development costs (not
- to mention interest on same).
-
- That said, there are some launchers that cost more, per pound
- of payload on orbit, than the Shuttle. But they are very small
- launchers that don't have many pounds of payload to spread
- their cost across.
