Space transfer vehicles for an affordable lunar exploration program

Abstract

The paper describes a lunar transportation system (LTS) based on a minimum cost approach to the lunar exploration scenario. A three-part exercise was conducted to minimize the cost and risk of lunar exploration, and the results of these optimization studies are presented. Particular consideration is given to the proposed concepts for the translunar injection stages, the common crew module of the LTS, the lander configuration, the LTS performance, and a concept of a long-range rover ('Rover First ') for discovering and mapping lunar resources for future utilization.
