“It’s been estimated that this programme overall will have saved Nasa maybe $30bn-40bn at least,” noticed Benji Reed, director of crew mission administration at SpaceX.

“Firm, fixed-price contracts and the kind of truly open partnership where we work together allows that kind of saving to happen and that kind of ability to allow Nasa to invest in more things and do other programmes.”
