High-C3 Applications for NASA's Space Launch System

Abstract

For numerous high-interest science targets in the outer solar system and elsewhere, the limits of available launch vehicles have placed significant constraints on mission designs. Even for the current generation of heavy-lift launch vehicles, baseline capabilities still impose limitations, for example, the outer solar system in areas such as launch window availability, transit time, science payload mass, time at destination, etc. Initial studies show benefits for ultra-high C3 missions from configurations of NASA’s Space Launch System(SLS) adding third or fourth payload stages.
