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

Basic Components
!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
