ONE.011_Rqmts/Ops-14 Comparison of AF and NASA Requirements  Concurrence in many areas: Reliability; De-orbit mass; Orbits; Abort Scenarios  NASA and AF requirements do not currently converge in certain areas:  Weight delivered to orbit:  Payload: K lbs  Crewed: 45+ K lbs  Responsiveness: AF < 12 hours to 2 days; NASA weeks  On-orbit capability: Duration and maneuverability substantially higher for NASA (ISS driven)  Sortie Rate: AF driven by future conflict scenario - could be high; NASA low  Human rating: AF no requirement; NASA needed in FY12 system  Weather: The AF has a requirement to operate in stronger winds, more precipitation and a wider range of temperatures.  Launch / Landing: AF has a requirement to operate from inland CONUS AFB.

ONE.011_Rqmts/Ops-15 Questions For Industry Requirements/Ops 1.What are the technology "long poles" to enable responsive space access (i.e., capable of achieving aircraft levels of cost, reliability and safety) over the next 25 years (Including vehicle, propulsion, ground infrastructure, operations, payloads, sensors, etc.)? Given your knowledge of currently funded NASA and Air Force programs, what would be your recommended technology roadmap? What changes and/or additional long-term technology investments should begin within the next seven years? 2.What RLV technologies does your company feel are state-of-the-art and ready for full-scale development today relative to your understanding of NASA and Air Force RLV requirements? 4.What is the earliest your company believes it is feasible to field a next generation RLV system(s) capable of meeting NASA and Air Force requirements? Please elaborate on your rationale and associated milestones. What would be the top 10 issues going into full-scale (or engineering and manufacturing) development of the next RLV (e.g., funding, technology maturity, immature requirements, joint program complexity, etc.)?

ONE.011_Rqmts/Ops-16 Questions For Industry Requirements/Ops (cont’d) 6.What are the drivers for meeting operability needs? What is the value of early flight demonstrations using state-of-the-art systems (existing engines, TUFI TPS, SOA avionics, electric valve actuators, etc.) for demonstrating operability? What relationship (if any) exists between the size of the launch vehicle and operability? Describe/define observed interactions between safety and operability needs 9.Given your knowledge of NASA and Air Force requirements, what degree of commonality does your company believe is possible between NASA and Air Force RLV architectures and associated elements (including ground and flight systems)? Does your company see commonality between the NASA/AF needs and mission requirements and a commercial opportunity? Do you believe a modular RLV concept is possible whereby we support a near term demonstrator in the 15-25K payload class, and that booster in turn is a modular component of a larger RLV?
