Robert L. Bayt, Ph.D. Verification and Validation Manager, Commercial Crew Program 2017
Advancing Human Spaceflight The vision of commercial human spaceflight to low-Earth orbit is a robust, vibrant enterprise with many providers and a wide range of private and public users. A successful human space transportation system will strengthen the International Space Station Program, allow NASA to focus on deep-space exploration, potentially reduce the cost of human access to space and significantly contribute to the national economy. NASA’s Commercial Crew Program serves two purposes: Public Purpose NASA Purpose Support the development of non-NASA Safe transport of NASA and NASA- markets for commercial human sponsored astronauts to and from transportation services to and from the station low-Earth orbit
Building a Bridge to the Future Building the Requirements Certification “Seeding” & Services the Market Pioneering Inter-Agency Approach Collaboration Requirements Verification Certification Commercial Approach
Building the Requirements • Provided high-level requirements for performance and mandatory requirements for safety, giving providers maximum flexibility • Conducted open industry forums very early in the development phase to gain feedback and weigh requirements against impacts to industry • Allowed use of alternate standards in many cases and framework for partnering the verification and validation of the system • Evolved requirements from previous human spaceflight and ISS COTS interface requirements
Requirements and Verification Framework Component Design Component Qualification System Qualification SMC-S-016 or Alternate Vehicle Tests Subsystem Tests Evaluate Component Performance Design and Flow Vs. ∆ P • Construction • Frequency Standards System Response Req’t • Dynamics Verification • Power Draw Comp. Ready for Qual Evaluate Integrated Performance Critical Component System Component Vehicle Model Functions Model Model Designed Verified for Validation Validation Validation and Built Hazard Reports properly Show components can NASA-STD-7009 May be rolled Evaluates all primary survive/operate in an and redundant into vehicle environment systems are verified testing Depiction of how Commercial Crew Program requirements and standards work together to ensure a qualified system that meets end user requirements
Certification Framework • Certification Roadmap developed by the Provider’s and approved by NASA to include: • Verification Strategies for each requirement • Joint Tests and Verifications with the ISS • Hazard Controls and Verifications • Human System Integration Strategy with Crew-in-the-Loop Testing • Flight Tests, Objectives and Plans • Joint Operations Planning
Moving Forward We are moving forward on the final development and certification of two safe, reliable and cost-effective, American- made crew transportation systems
Summary The Commercial Crew Program continues to execute its mission under the framework that was outlined in 2010 This allows industry to meet critical needs, while providing a stepping stone to the future of commercial space
