NASA astronauts Butch Wilmore and Suni Williams arrived at the ISS aboard Boeing's Starliner spacecraft last June. The duo were flying the capsule's first crewed flight test, which was expected to stay in orbit for about 10 days before flying the pair back to Earth.

The flight was scrubbed on Wednesday night, and the astronauts will return to the launchpad for their trip to the International Space Station.
