NASA’s Boeing Starliner Crew Flight Test Launch – June 5, 2024 (Official NASA Broadcast)

Watch live as two NASA astronauts launch from Boeing’s Starliner spacecraft, which is one of the final steps to certification. Launch of the ULA (United Launch Alliance) Atlas V rocket and Starliner spacecraft is targeted for 10:52 a.m. EDT Wednesday, June 5 (1452 UTC) from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.

The two NASA astronauts aboard, flight commander Butch Wilmore and pilot Suni Williams, will test the end-to-end capabilities of the Starliner system, including launch, docking, and return to Earth after a one-week stay docked to the International Space Station, the Starliner, and crew will land under parachutes in the western United States.

The launch attempt on May 6 was scrubbed due to a faulty oxygen relief valve observation on the United Launch Alliance Atlas V rocket Centaur's second stage. The launch attempt on June 1 was scrubbed due to an observation of a ground launch sequencer.

Launch coverage on NASA+ (https://plus.nasa.gov) will end shortly after Starliner orbital insertion. NASA Television (https://nasa.gov/nasatv) will provide continuous coverage leading up to docking and through hatch opening and welcome remarks.
