Non-NASA revenue key for CST-100

摘要

Boeing may yet shelve future development of its CST-100 capsule, despite a recent award of more than S460 million from NASA's programme to transport astronauts to the International Space Station (ISS). "Our base business case is based on transportation to ISS through 2020," says John Elbon, Boeing's vice-president of space exploration. Though not formalised, the company requires at least two flights per year from NASA to make the project viable.
