Starliner spacecraft just took a major step toward first crewed flight

Boeing’s CST-100 Starliner spacecraft has been stacked atop the United Launch Alliance (ULA) Atlas V rocket ahead of its first crewed flight next month.

After being fully fueled, engineers transported the Starliner spacecraft from Boeing’s Commercial Crew and Cargo Processing Facility (C3PF) to ULA’s Vertical Integration Facility (VIF) at the Kennedy Space Center in Florida, on Tuesday.

Boeing shared a video showing the Starliner’s six-mile journey to the Atlas V rocket.

“Functionally, this rollout was similar in nature to previous rollouts, treating the spacecraft with the greatest care and detail,” Boeing’s Amanda Ireland said in a release.

Prepareation work will continue at the VIF to ensure the Atlas V and the spacecraft are properly communicating with each other.

NASA and Boeing are currently targeting May 6 for the first crewed flight, which will carry NASA astronauts Butch Wilmore and Suni Williams to the International Space Station (ISS).

Boeing has had a tough time getting the Starliner ready for its first crewed test. The spacecraft’s maiden flight in 2019 ended in failure when the vehicle was unable to make it to the ISS. The mission surfaced a slew of issues with the Starliner’s flight systems, which engineers spent years putting right. The spacecraft made it to the ISS for a short stay in another test mission in 2022, though more issues had to be resolved after that.

The first crewed flight has been delayed a number of times, but this time it really does appear that the Starliner will be flying astronauts to the space station in just a few weeks from now.

If the test flight goes according to plan, NASA will have a second commercial spacecraft for crewed trips to orbit alongside SpaceX’s Crew Dragon vehicle, which has been flying astronauts since 2020.

Two NASA astronauts are making final preparations directly ahead of the first crewed launch of the new Boeing Starliner capsule, which will launch from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida later tonight, Monday May 6. Butch Wilmore and Suni Williams will be aboard for liftoff at 10:34 p.m. ET (here's how to watch), when an Alliance Atlas V rocket launchesthe Starliner for its test flight to the International Space Station (ISS).
