NASA released redacted versions of the contracts the agency signed with Boeing and SpaceX in September 2014 to begin the Commercial Crew Transportation Capability phase of final development and certification work. The contracts outline goals and obligations that both NASA and the providers agreed to, however, the focus of the agency’s involvement is not just in milestones but in the day-to-day work the NASA team is performing. The agency’s efforts revolve around understanding the providers’ designs and ensuring progress is being made toward meeting safety and performance requirements before crew flight tests and missions to the International Space Station.
