Next up: Launch; Boeing’s Starliner takes trek to Cape Canaveral

The spacecraft has left the building.

Boeing’s CST-100 Starliner set to take its first humans on board during the Crew Flight Test (CFT) mission next month was transported from Boeing’s Commercial Crew and Cargo Processing Facility at Kennedy Space Center on a 10-mile trip over to Cape Canaveral Space Force Station.

It arrived to United Launch Alliance’s Vertical Integration Facility early Tuesday where it will be placed atop an Atlas V rocket ahead of the planned launch from Canaveral’s Space Launch Complex 41 as early as May 6 taking NASA astronauts Butch Wilmore and Suni Williams on what is planned to be an eight-day mission to the International Space Station.

Boeing completed fueling of its spacecraft at the Starliner production facility adjacent KSC’s massive Vehicle Assembly Building earlier this month, getting five commodities to be used during its trip to and from the ISS.

“Samples were taken and specialized tests were conducted throughout the propellent loading process to ensure the safety of the team performing the operation and the safe operation of the spacecraft on orbit,” said Mark Sorensen, Starliner CFT Crew Module lead.

Before it left the building, Boeing performed a final weigh-in that also acted as the center-of-gravity check that had to be within a volume about the size of a quarter. Teams signed off on that, and then Starliner was loaded by crane atop ULA’s transport vehicle called “K-MAG” for the overnight trip between KSC and Canaveral.

Williams and Wilmore were joined by NASA astronauts Mike Fincke and Scott Tingle, Canadian Space Agency astronaut Joshua Kutryk and JAXA astronaut Yui Kimiya to see Starliner off. Fincke, Tingle and Kutryk have all been announced as crew of Starliner’s next planned mission, Starliner-1, while Kimiya is assigned for a long-duration stay on board the ISS in 2025, so could become its fourth crew member.

Starliner is the second of two spacecraft created as part of NASA’s Commercial Crew Program alongside SpaceX’s Crew Dragon. SpaceX, though, completed its first test crew mission back in 2020 and has since flown what is now a fleet of four Crew Dragons an additional 12 times on both private and NASA missions carrying 50 humans into space in the last four years.

Boeing, though, faced a series of delays highlighted by an uncrewed test flight in December 2019 that failed to rendezvous with the ISS forcing Boeing to refly its uncrewed dry run before it set up for the human test flight. The second try went well, though, but only 2 1/2 years after in May 2022. Further fixes were needed to the spacecraft as well, which have pushed CFT an additional two years past the last time it flew.

But everything is now queued up for the final push to space. The Atlas V rocket has been on site at the VIF since February, and ULA completed its CFT Mission Success Review earlier in April.

“Doing everything thing we can to give Butch and Suni a boring trip to ISS on the Atlas,” said ULA President and CEO Tory Bruno on X.

If all goes well with CFT, the first operational mission Starliner-1 could fly as early as February 2025.

While SpaceX is in the middle of its eighth operational flight, Crew-8, with Crew-9 slated for August, once Boeing’s Starliner is certified, the two companies will trade off flights to the ISS so each makes only one trip there per year.

Boeing has six operational flights to the ISS on contract so it can support rotational crew missions through 2030, when NASA has said it plans to begin decommissioning the ISS.
