Launch preparations are proceeding toward a liftoff of Boeing's CST-100 Starliner spacecraft on a United Launch Alliance Atlas V rocket on a flight test to the International Space Station at 6:54 p.m. on Thursday, May 19.

Watch on NASA Television, the NASA app, and the agency's website.

Known as Orbital Flight Test-2 (OFT-2), this is the second uncrewed flight for Boeing's Starliner spacecraft as part of the agency's Commercial Crew Program. OFT-2 will demonstrate the end-to-end capabilities of the Starliner spacecraft and Atlas V rocket from launch to docking to a return to Earth in the desert of the western United States. The mission will provide valuable data toward NASA certifying Boeing's crew transportation system for regular flights with astronauts to and from the space station.
