Rotating workforces may save money in the short term, but they undermine the development and preservation of team know-how, reducing the return on investment in the long term and excising technical expertise from NASA centers of excellence. While the press made much of the "New Space" companies that won contracts to fly to the moon, these teams worked closely with NASA centers and NASA experts. But slashing NASA's teams and centers with their hard-won group know-how now in anticipation of a commercial-dominant spaceflight future would not only represent a colossal waste of taxpayers' money—it would lose the knowledge America needs to retain its dominance in spaceflight.
