Boeing’s Starliner crew will attempt to launch its first crewed mission to space on Wednesday morning with NASA astronauts Butch Wilmore and Suni Williams on board. The Starliner capsule is scheduled to take off from the Cape Canaveral Space Force Station in Florida at 10:52 a.m. ET. If successful, the two are expected to return to Earth in approximately 10 days.

NASA and Boeing both that the capsule, rocket and ground support equipment are ready for the launch after two previously aborted attempts. In May, there was an issue with an oxygen relief valve that delayed and subsequently led to the cancellation of the first launch attempt. Then, on June 1, the United Launch Alliance crew found another issue with a rocket, which halted the second attempt.

Once the Starliner launches, a capsule will break away with Wilmore and Williams inside and use its own engines to take the pair to the International Space Station . Wilmore and Williams helped develop the capsule.

The two astronauts will stay at the space station to test the Starliner spacecraft for certification — potentially putting Boeing in competition with SpaceX. Boeing has with NASA as part of its Commercial Crew Program.

Starliner first did an unmanned test flight in 2019, but a software glitch prevented it from making it to the space station. A second test flight in 2022 also dealt with issues. A year later, Boeing postponed a crewed launch several times and then canceled the launch after finding more issues with the crew capsule.

Today’s launch is significant because it could open doors for more private airline companies to collaborate with NASA.
