                 CONSTELLATION
                      Background on NASA Studies


     !Exploration Systems Analysis Study (ESAS) defined
      only a limited framework for Lunar surface activities
     !To prepare for early transportation milestones, it was
      necessary to assess impacts of eventual surface
         activities on Altair and Ares V
     !Lunar Architecture Team Phase 1 (LAT1) in the fall of
      2006 attempted to put more structure to surface
      activities and refine concepts
     !Lunar Architecture Team Phase 2 (LAT2) in
      spring/summer of 2007 examined a number of additional
      approaches

                          Background on NASA Studies (cont’d)


     !The Constellation Lunar Architecture Team (CxAT
      Lunar) started in fall 2007 and is currently preparing for
      a June 2008 review
            • Emphasis is on the transportation architecture and understanding
                   performance trades
            • Examining key driving requirements from the surface systems that
                   impact transportation elements

        !Habitation, eventually for long duration stays
               • Must provide both life support and safe haven

        !Mobility to enable expanded exploration, for both
         humans and payloads
        !Power infrastructure for both day and night operations
        !Communications, both to Earth and within the lunar
         community
        !Science support, labs and infrastructure
