Human Spaceflight Certification

CCiCap Base Phase includes Integrated HSF Certification Effort

– Atlas V compliance with NASA CTS-1100 and spacecraft requirements

– Integrate Crew Safety baseline

– Integrate Loss of Crew/Mission PRA

– Integrate Hazard Analyses Leverage NASA Atlas V Certification

– Atlas V certified to NASA Risk Category 3 (highest certification level)

– Atlas V nuclear safety launch approval

Human Spaceflight Certification is a combination of technical/operations requirements satisfaction, flight history

NASA can leverage the body of evidence already availablefor Atlas V HSF Certification
