A United Launch Alliance (ULA) Atlas V rocket carrying Boeing’s Starliner capsule on the Orbital Flight Test lifted off on Dec. 20 at 6:36:43 a.m. EST, from Space Launch Complex-41 at Cape Canaveral Air Force Station.

“We had a successful launch and initial indications are that we demonstrated the launch vehicle test objectives, performance enhancements, and the mission unique modifications developed for the safety of human spaceflight,” said Tory Bruno, president and CEO, United Launch Alliance. “We achieved spacecraft separation as planned. We will continue to support our Boeing and NASA partners as they work to bring Starliner home.”
