Boeing launched its first Starliner flight with astronauts on Wednesday, beginning a crucial final flight test of the long-delayed spacecraft.
The launch took off at 10:52 a.m. ET from Cape Canaveral, Florida with two NASA astronauts aboard. Starliner is carried by an United Launch Alliance’s Atlas V rocket and bound for the International Space Station.
More than 10 minutes into the flight, the rocket and capsule were operating as expected as the vehicles ascended into orbit, according to flight directors in mission control.
Boeing’s crew flight test aims to certify the Starliner system as capable of carrying NASA astronauts to-and-from the ISS.

After launching, Starliner will fly in space for about 25 hours before a planned docking with the International Space Station at 12:15 p.m. on Thursday. The astronauts will then spend about a week on the ISS, focused on testing Starliner, before returning to Earth.
Wednesday’s liftoff comes after a series of attempts to launch the mission. On Saturday, a launch attempt was called off in the final minutes of the countdown due to a problem with one of the computer’s that provides ground support to the rocket. In early May, another attempt was called off due to an issue detected with the rocket itself.
United Launch Alliance – or ULA, a joint venture of Boeing and Lockheed Martin – replaced the rocket’s problematic valve after the May attempt and replaced a faulty part in the ground infrastructure computer after Saturday’s attempt.

Butch Wilmore and Suni Williams are flying on Starliner, with the former serving as the spacecraft’s commander and the latter as its pilot.
Wilmore joined NASA in 2000 and has flown to space twice previously on the Space Shuttle and Russia’s Soyuz. Before NASA, Wilmore was a U.S. Navy pilot.

Williams was selected by NASA in 1998 and has also flown to space twice before, on the Space Shuttle and then the Soyuz. Williams was also a Navy pilot, like Wilmore, before joining the space agency.

Starliner launches on ULA’s Atlas V. The rocket debuted in 2002, and the Starliner crew flight test represents its 100th launch.
The capsule itself is built to carry as many as four NASA astronauts per flight and more than 200 pounds of research and cargo. The spacecraft lands using a parachute and airbag system. Starliner is reusable, with each capsule designed to fly as many as 10 missions.
