NASA’s Starliner decision was the right one, but it’s a crushing blow for BoeingArs TechnicaIt's unlikely Boeing can fly all six of its Starliner missions before retirement of the ISS in 2030.

A decade later the Starliner program finds itself at a crossroads after Boeing learned it will not complete the spacecraft's first Crew Flight Test with astronauts onboard. NASA formally decided Saturday that Butch Wilmore and Suni Williams, who launched on the Starliner capsule June 5, will instead return to Earth inside a SpaceX Crew Dragon spacecraft. Put simply, NASA isn't confident enough in Boeing's spacecraft after it suffered multiple thrusters failures and helium leaks on the way to the ISS.
