Though the Space Shuttle program lasted 30 years and built the ISS, it fell short of NASA's goals for cost, reusability, and reliability. Can a program be both a worldly success and a policy failure? In this Space Policy Edition, we dissect a classic space policy paper and debate its relevance today.
