Boeing and NASA Stand Down Starliner Launch

Update Wednesday, August 4th at 10:00 a.m.

Boeing scrubbed Tuesday’s mission to the International Space Station after engineers discovered an issue with the Starliner spacecraft’s propulsion system. Teams have ruled out a number of potential causes, including software, but more time is needed. And the clock is ticking. If the Starliner problem cannot be quickly resolved, Boeing will have to stand down to make way for the higher-priority launch of a SpaceX Dragon cargo ship later this month that's bound for the same docking port on the ISS as the Boeing capsule. Boeing needs to successfully complete this test flight before NASA will rate the Starliner safe to carry humans.
