  2. TAAT OBJECTIVES • Identify key technologies that can advance Space Exploration • Determine technology interaction to achieve common goals • Define technology demonstrations that can be done soon - what are affordable - what can be partnered Maximize use of existing Assets- facilities, H/W, FSW, skills, etc.

  3. TAAT Activity • The Technology Applications Assessment Team selected several applications that would add value for Exploration • The Team is independently assessing these applications for future implementation • The Team is supporting similar technology assessments in other areas: • DARPA/NASA tasks • MacGyver team • Human Exploration Framework Team (HEFT) • Office of the Chief Technologist (OCT)CISS Commercial In-Space Servicing • Future in Space Operations (FISO)

  5. Satellite Servicing Assessments Description: • To support satellite servicing studies underway in the Agency (HQ, GSFC, JSC) and DARPA. • Identify transportation options, human habitation, and space vehicle options that can support satellite servicing scenarios. • Identify technologies (e.g. heavy-lift launch) that can enable or enhance human and robotic servicing missions • Examine the commercial viability of satellite servicing for ops scenarios, concepts & technologies identified. • Define a near-term, servicing demonstration mission Schedule/Cost: Approach: • Support NASA/DARPA Manned GEO Servicing Study thru April 2011 • Support GSFC Servicing Study thru April 2011 • Demonstration Mission Definition - Large, multi-satellite GEO servicing (provide life extension via end-of-life relocations) • Interface with NASA/DARPA study teams to provide support in areas noted • Conduct Notional Mission trades and definition especially in human GEO servicing and use of heavy-lift launch systems. • Identify key technologies, ops scenarios, and system concepts • Integrate into a near-term servicing demonstration mission definition • Supports requests from NASA, GSFC, JSC, SOMD, OCT, DARPA stakeholders • Provides data to same to support decision-making Justification:
