- Abstract
NASA’s Constellation Program (CxP) is responsible for the definition, design, development and operations of the flight, ground and mission operations elements being developed by the United States for the human exploration of the moon, Mars and beyond. This paper provides an overview of the latest CxP technical architecture baseline, driving requirements, and reference missions for initial capability to fly to the International Space Station (ISS) and to the moon. The results of the most recent design decisions and analyses supporting the architecture, including Ares I, Ares V, Orion and Altair will be presented. Of particular importance to the success of the Constellation Program is the systems engineering approach being used to establish and manage performance and mass margin. The margins of interest include those for the systems to access low earth orbit for ISS and for injection into a translunar trajectory. These margins are tightly coupled, given the parallel development of the launch vehicles and payloads. The overall CxP technical margins definition and management strategy will be presented, as will the results of a new state-of-the-art technique to quantify margins based on stochastic analyses using historically based probability density functions.
