In order to assure safety, NASA has the
responsibility, working with the RSA and the Cooperating Agencies of the Space
Station Partners, to establish overall Space Station safety and mission
assurance requirements and plans.
RSA will develop detailed safety and
mission assurance requirements and plans, using its own requirements for its
Space Station hardware and software. Such requirements and plans must meet or
exceed the overall Space Station safety requirements and plans.
Requirements for which meet or exceed criteria
are not appropriate will be determined by agreement of the Parties. RSA will
have the responsibility to implement Space Station safety and mission assurance
requirements and plans with respect to the elements and payloads it provides
throughout the lifetime of the program, and to certify that such requirements
and plans have been met. NASA will have the overall responsibility to certify
that all Space Station elements and payloads are safe.
