AGENDA
  • Outputs from Workshop 1
  • Research Area 2 Hierarchy
  • Primary Goals for Workshop 2
  • Complete Research Area Hierarchy
  • Identify Broad Research Topics
  • Identify Specific Tasks
  • Identify High Priority Tasks
  • Low-hanging fruit to enable safer, more reliable
    Commercial Space Transportation
  • Lowering cost, improving mission rate are force
    multipliers
  • Additional Goal ? identify efficient means to
  • Prevent duplication of efforts by
  • NASA, DOD, NSF, and possibly NOAA, DOT and other
    USG agencies
  • University and/or private sector community
  • Leverage current/prior RD efforts for FAA/Comm
    Space industry benefit

3
New Areas we addressed
  • Man rated vehicle safety technology
  • payloads
  • ECLSS
  • Safety enabling sensors recorders
  • Insurance reduction/learn from other
    transportation modes
  • NASA Commercial RLV technology roadmap study
