ULA launches Atlas V rocket carrying Boeing's Starliner spacecraft

The United Launch Alliance (ULA) has launched an Atlas V rocket from Florida's Space Coast carrying with it Boeing's CST-100 Starliner spacecraft.  The capsule is bound for the International Space Station (ISS) for its second uncrewed test flight.

On Wednesday, teams rolled the 172-foot-tall Atlas V and Starliner from the hangar to the launchpad, Space Launch Complex-41, at Cape Canaveral Space Force Station. After the 1,800-foot journey, the vehicle was prepped for lift-off and begin fueling.

The Orbital Flight Test-2 is the final step before a test flight with astronauts later this year.  The spacecraft's commander seat is occupied by a manikin named "Rosie the Rocketeer." Her seat will be outfitted with sensors to collect data and better understand what human astronauts will experience.  You can read more about the OFT mission and see photos from Thursday's launch here.

This is Boeing's third attempt to complete the orbital flight test since 2019.  Starliner will dock at the ISS around 7 p.m. Friday or 24 hours after launch if all goes well.
