The Space Transportation System

Abstract

The accomplishments and present budget concerns of the Space Transportation System (STS) program are discussed. The Shuttle, with the most advanced operational engine in the world and the largest rocket motor and external tank ever developed, is shown to be a successful, state-of-the-art achievement with enormous capabilities for future exploitation. The readjusted price of $71M (1982$) for a dedicated mission for the period FY 86-FY 88 is nearly twice the price estimated at the beginning of the 12-year program. Additional flights above the sixteen plus missions necessary for the U.S. government's NASA and DOD National Security payloads, are offered to U.S. and foreign, commercial and civil customers, to help recover the marginal costs of anticipated future payloads. Aspects of the present bid scheme, with a $74.0M (82$) minimum bid commencing with FY 1989, are discussed.
