  • 3. HEFT Overview• HEFT Strategy: Create a decision framework for human space exploration that drives out the knowledge, capabilities, and infrastructure NASA needs to send people to explore multiple destinations in the Solar System in an efficient, sustainable way• HEFT Goal: Generate a process that evolves into a long term, permanent NASA activity to support human space flight (HSF) strategic planning – Initially focused on standing up the organization, getting it functioning, and conducting a full iteration of the process – Outcome of the process was recommendations for human space flight capabilities and missions for 5-, 10-, 15-, and 20-year horizons, with Mars as the ultimate destination• HEFT Impact: Informed the FY2012 Program Planning, Budget, and Execution process – Identified requirements for technologies and advanced systems capabilities based on investment strategies and design reference architectures for human missions to destinations beyond low-Earth orbit (LEO) – Met Executive Branch guidance, critical Stakeholder objectives, and HSF objectives and constraints – Is sustainable and affordable (fits within projected NASA HSF budget)5-486373 3

  • 6. Key Outcomes• The process of analyzing 9 investment portfolios was effective in exploring a broad technical and programmatic trade space – Evaluated them against Executive Branch Guidance, Critical Stakeholder Interests, and Benefit and Constraint Figures of Merit• Derived key insights from a large, complex dataset and identified options for: – Enabling and Enhancing Technology Development and Demonstration activities – Advanced Systems Developments including Crewed Spacecraft and Launch Vehicle – Changing the way NASA does business and opportunities for partnerships with other U.S. government agencies and international partners• Further work is required to refine the Design Reference Missions and cost and schedule estimates – This can eventually lead to a NASA integrated architecture for human exploration beyond LEO Charting a Balanced Path Forward5-486373 6
  • 7. General Findings• Affording human exploration within expected budgets is a challenge• NASA human space flight is a demanding and risky enterprise requiring sustained resources• Safety is the cornerstone of viable options• Commercial crew helps test our assumptions (like NetFlix did to Blockbuster)• With ~$40B available over 10 years, significant progress can be made• “Lean” developments are essential to extending and sustaining human presence beyond LEO• Transitioning approaches used on relatively small projects to large (higher dollar value) programs/projects can have big payoffs Changing the Agency’s Business Model5-486373 7

  • 12. Lean Cost and Schedule Implementation Approaches• Evolutionary Block Progression – Applies to a variety of projects, allowing a stepped approach to requirements maturation, incremental capability, technology infusion, development, and implementation• Parallel Government/Industry Development – Allows rapid start by Government, while maturing requirements and competitive acquisition strategy• Flying Class C/D, or “First Build”, and Sticking to the Designation – Applies to key technology demonstration missions and allows for rapidly advancing a selection or suite of technologies — proto-flight hardware• Learning Curves – Applies to multiple unit production and also can drive infrastructure requirements early in the process via pathfinders• Skunkworks Approach – Estimated schedule decreased by more than 20% • For large systems, long-lead items dominate schedule Finding Efficiencies that Maximize Budget5-486373 & Reduce Time to Market 12
  • 13. Summary• NASA and the Nation will be in a constrained budget environment for the foreseeable future• NASA’s program management and technical community must find ways to meet objectives with more efficient use of resources• The future of human exploration is in the balance Living Within Our Means While Delivering Excellence5-486373 13
