3. The EVA System Design Approach Launch and Entry • A single spacesuit system with two configurations which share many components • Common, evolvable infrastructure • Minimum set of hardware to meet all mission phase requirements • Modular, reconfigurable, component-based open architecture In-space Contingency • Lunar Surface 3

4. Photos on page 3: • 3 photos depicting the three conditions to which the EVA suit will be exposed: • TOP: Launch and Entry (crew inside the spacecraft) • MIDDLE: In-space Contingency Microgravity environment (crew outside spacecraft) • BOTTOM: Lunar Surface 1/6 gravity environment (crew walking on Moon)

Graphic on page 8: • “Pie” Chart showing successful offeror and subcontract team members with responsibilities: • Oceaneering - Program Management, Systems Engineering, Crew Survivability Thermal Garment • USA - Design for Operations, Logistics, Processing • Cimarron - Flight Software • Harris - RF Communications • Honeywell - Life Support Technology, Avionics • Paragon - Thermal Control System • Airlock & David Clark - Pressure Garments, Gloves, Helmet

10. Orion “Human In The Loop” (HITL) test plan Orion Testing Philosophy • Orion planning a comprehensive test program which program is critical to the success of the certification/qualification of Orion • Ground Test Article is early vehicle test to provide better defined acoustic environments for components and systems • Orion has adopted a “Test Like You Fly” approach • Validated by Flight Test Program (e.g. - Incorporation of landing strategies into later test flights) • Orion will have humans involved in testing at multiple levels 10

11. Candidates for HITL Testing in Vacuum Chamber • Orion will perform thermal vacuum testing for qualification • HITL vacuum chamber test candidates determined through normal requirement verification definition process and a detailed HITL test study • Candidates distilled in study from: • Historical Testing • Vehicle Design • Program Architecture • Test Facility Capabilities • Training Methodology • Many HITL tests planned from component/subsystem level through spacecraft level • Three primary focus areas requiring large scale testing, potentially in a vacuum chamber identified • Hatch Operations • ECLSS • Crew Familiarization/Training 11

12. Summary • Orion examined large range of testing requiring Human in the loop • Recognized inherent risk of performing human vacuum testing. Accept the risk when required • Included unique aspects of vehicle design, previous program experience and benefits for complete system testing • Resultant set of tests were defined with specific needs • Orion has put in place appropriate test program to minimize known risks with mitigations that provide representation of humans in vacuum environments as warranted by design verifications • Orion test program currently does not include humans in a vehicle in a vacuum environment; however if the need is demonstrated, testing could be added • Ongoing fact finding: Exploration and Space Operations Committee members plan to continue fact finding as acceptance test plans evolve. 12

13. Overall conclusions • Continue to see highly maturing architecture planning. • These plans are flowing into acquisition and test in a highly commendable way. • Superb Team Development across multiple centers and disciplines. • Next: • Capt. Rick Hauk: Lunar Capabilities Concept Review • Dr. David Longnecker: • Lunar Science Institute • Decadal Survey for Physical and Life Sciences Research for 2010-2020 • Radiation Hazard Development 13
