Ever since the US retired the space shuttle, it's relied upon Russian rockets to get crews to and from the International Space Station. 2017 was meant to be the year that both SpaceX and Boeing restored some hometown pride, but the latter's now had to bow out. GeekWire is reporting that the aerospace firm's space taxi, the CST-100 Starliner, won't be ready for manned spaceflight until 2018. That means that not only is NASA's timetable going to have to change, but SpaceX is left as the agency's only hope. If Elon Musk can keep the Dragon's development program on schedule, then his company is virtually guaranteed to win the new space race.
