NASA will provide live coverage of prelaunch and launch activities for the agency's Boeing Crew Flight Test, which will carry NASA astronauts Butch Wilmore and Suni Williams to and from the International Space Station.

Launch of the ULA (United Launch Alliance) Atlas V rocket and Boeing Starliner spacecraft is targeted for 12:25 p.m. EDT Saturday, June 1, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Starliner will dock to the forward-facing port of the station's Harmony module at approximately 1:50 p.m., Sunday, June 2.

Wilmore and Williams will remain at the space station for about a week to test the Starliner spacecraft and its subsystems before NASA works to complete final certification of the transportation system for rotational missions to the orbiting laboratory as part of the agency's Commercial Crew Program.

NASA, Boeing, and ULA scrubbed the previous launch opportunity on May 6 due to a suspect oxygen relief valve on the Atlas V rocket's Centaur second stage. Since, teams have removed and replaced the valve, and completed an assessment of Starliner's performance and redundancy after discovering a small helium leak in the spacecraft's service module.

As part of the helium leak investigation, NASA and Boeing conducted a follow-on propulsion system assessment to understand potential helium system impacts to some Starliner return scenarios. NASA also completed a Delta-Agency Flight Test Readiness Review on May 29 to evaluate all work performed and flight rationale before proceeding toward launch.
