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

Support the development of non-NASA markets for commercial human transportation services to and from low-Earth orbit

NASA Purpose

Safe transport of NASA and NASA- sponsored astronauts to and from the station

Building a Bridge to the Future

Requirements  Verification  Certification

Commercial Approach Inter-Agency Collaboration Certification & Services Building the Requirements “Seeding” the Market Pioneering 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

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

We are moving forward on the final development and certification of two safe, reliable and cost-effective, American- made crew transportation systems

Moving Forward

Summary

The Commercial Crew Program continues to execute its mission under the framework that was

• utlined in 2010

This allows industry to meet critical needs, while providing a stepping stone to the future of commercial space
