A next generation Space Shuttle concept

Abstract

Work done over the past two years for the NASA/Johnson Space Center on possible evolutionary paths of the present Space Shuttle Orbiter and system to meet the goals of enhanced safety, mission suitability economy, and robustness is summarized in this paper. Three vehicle concepts are described: an advanced technology one-and-one-half stage vehicle, a near-term evolved Space Shuttle system closely related to today's Orbiter in concept and appearance, and an Orbiter-Glider which might be appropriate for use with emerging large space launch vehicles.
