When is an economic forecast strong enough to justify building a spacecraft? In this 1972 Senate testimony, Oskar Morgenstern and Klaus P. Heiss defend Mathematica’s case for the Space Shuttle while acknowledging its dependence on projected missions, engineering assumptions, and uncertain costs. Their distinctive emphasis falls on payload economics: reusable transport might save money not only on launches but by allowing satellites to be retrieved, repaired, and designed with less costly redundancy. Committee questioning exposes the boundary between comparing economical means and deciding national priorities. The witnesses argue that, given continued American space activity, development should proceed; they do not establish that space spending outranks other public uses of funds. The exchanges offer a concrete encounter with investment analysis at the point where qualified evidence becomes a recommendation to act.
