Description of Driving Event:
Initial Operational Capability of Crew Return Vehicle (CRV)
Lesson(s) Learned:
The current ISS requirement is for a single Crew Return Vehicle (CRV). Crew safety over the life of the ISS requires the availability on orbit of two CRV's, both of which is capable of accommodating the entire crew. The Soyuz capsule, designated as the interim CRV, does not have a full crew capability. Also, it is uncertain that sufficient Soyuz capsules and their launches will be available to supply the needs of the ISS.
Recommendation(s):
NASA should accelerate its program to develop and deploy two full-crew CRV's and take whatever measures are necessary now to ensure the availability of sufficient Soyuz capsules and launchers until the CRV's are ready.
Evidence of Recurrence Control Effectiveness:
The item remains open and under assessment. The ISS Program has assessed the need and feasibility for a second CRV on-orbit aboard the Space Station. A Tiger Team, led by the Astronaut Office, was chartered to assess the overall effectiveness. The Tiger Team presented its findings to the Lead Center Director and the Associate Administrator for Space Flight, who requested that additional analysis be performed in alternative configurations. NASA is engaged in on-going discussions with the Russian Space Agency regarding the acquisition of additional Soyuz vehicles. Due to the current Russian economic problems, NASA closely monitors the status of the Soyuz production required to support the ISS at the manufacturer, Energia. NASA is engaged in on-going discussions of the procurement of additional goods and services from RSA. The procurement will provide the cash flow necessary to sustain the production levels of Soyuz vehicles that the ISS requires until the CRV is available. These discussions will continue in the overall context of determining Russia's ability to satisfy its commitment as an international partner.
