Dual Mission Scenarios for the Human Lunar Campaign - Performance, Cost, and Risk Benefits

Abstract

Abstract-NASA's future human lunar campaign faces significant performance, cost and risk challenges. These include:o Providing the capability to access large portions of the lunar surface for expanded science and exploration within the performance constraints of the integrated transportation system; o Minimizing the annual cost of the lunar campaign; and o Minimizing operational risk including probability of loss of mission (PLOM) and probability of loss of crew (PLOC)Innovative lunar operations scenarios which address these challenges are potentially feasible based on the concept of dual, sequential missions utilizing a common crew and a single Ares I/Crew Exploration Vehicle (CEV). Dual mission scenarios possible within the scope of baseline technology planning include Outpost-based sortie missions, dual sortie missions, and enhanced Outpost deployment. Additional mission scenarios are potentially possible with the development of advanced capabilities. These include abort to the lunar surface options and Lander reusability options.
