Scaled Composites SpaceShip One / White Knight

Ten years ago today, on 21 June 2004, Mike Melvill flew SpaceShip One to an altitude of 100.124 kilometers, becoming the first pilot to qualify for the FAA’s commercial astronaut wings. The flight was a milestone for Scaled Composites in its quest to win the $10-million Ansari X-Prize, which was finally won on 4 October 2004.

At the time, many people assumed that suborbital spaceflight would soon be commonplace. Today, however, some view the event with ambiguity, if not disappointment, as commercial suborbital flights have not yet begun.

When viewed in systems-engineering terms, the delay in the start of the commercial operations should not be considered surprising, though, or cause for great concern. The late G. Harry Stine pointed out that human beings tend to view progress in linear terms. Our brains are hard-wired that way. But, in fact, technological progress and economic growth (like biological growth and most other natural phenomena) are not linear. They follow exponential growth curves.

As a result, Stine pointed out, human beings almost always overestimate what can be accomplished in the near term and underestimate what can be accomplished in the long term.

What we are seeing today, with delays in suborbital spaceflight, confirms the first half of Stine’s prediction. There is every reason to believe that suborbital spaceflight will confirm the second half of his prediction, too, in the years to confirm — as did computing, communications, aviation, and many other industries.
