NASA astronauts Butch Wilmore and Suni Williams are safely in orbit on the first crewed flight test aboard Boeing's Starliner spacecraft bound for the International Space Station.

As part of NASA's Boeing Crew Flight Test, the astronauts lifted off at 10:52 a.m. EDT Wednesday on a ULA (United Launch Alliance) Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida on an end-to-end test of the Starliner system.

"Two bold NASA astronauts are well on their way on this historic first test flight of a brand-new spacecraft," said NASA Administrator Bill Nelson. "Boeing's Starliner marks a new chapter of American exploration. Human spaceflight is a daring task – but that's why it's worth doing. It's an exciting time for NASA, our commercial partners, and the future of exploration. Go Starliner, Go Butch and Suni!"
