Jeff Foust, WASHINGTON — NASA is beginning to study a contingency option for maintaining access to the International Space Station should commercial crew vehicle development experience delays, one that would turn test flights of those vehicles into operational missions. Speaking at the Federal Aviation Administration Commercial Space Transportation Conference here Feb. 8, Bill Gerstenmaier, NASA associate administrator for human exploration and operations, said using the planned crewed test flights as crew rotation missions was one option under consideration should neither Boeing nor SpaceX be certified for regular crew rotation missions by the fall of 2019, when NASA's access to Russian Soyuz spacecraft ends. "Those test flights might be able to be extended a little bit, fly a little bit longer, maybe fly a little bit of crew, and they could be kind of an operational mission," he said in response to a question after a luncheon speech at the conference. "That's something we're beginning to discuss with both SpaceX and with Boeing." In a later interview, Gerstenmaier said those changes would involve extending the length of the crewed test missions, currently planned for two weeks, to bridge whatever schedule gap until at least one company has a NASA-certified vehicle ready for regular missions.
