Isn’t that 500 million “price per launch” of the Space Shuttle a bit low?
I know the Space Shuttle “launch interval was very long. They seldom were launchedcwithin 3 weeks of each other, even when two different Shuttles were used.
A half billion per launch is actually a bit high, in the dollars of the time, it was a bit north of $400 million per launch. NASA estimated that shuttle launches were going to run under $10 million per launch, so, they were off by a factor of about 40.
