Boeing’s Starliner spacecraft has embarked on its first crewed test flight, carrying NASA astronauts Butch Wilmore and Suni Williams. This milestone follows years of development and delays, marking a critical moment for Boeing as it aims to compete with SpaceX’s Crew Dragon.
The Starliner capsule launched from Cape Canaveral Space Force Station in Florida aboard a United Launch Alliance Atlas rocket. Commander Wilmore expressed gratitude to those involved. Acknowledging the challenges faced, he said: “When the going gets tough – and it often does – the tough get going, and you have.”
The mission, expected to last just over a week, involves extensive testing of the spacecraft, including manual control by the astronauts. After a flawless ascent, Starliner will take 24 hours to reach the International Space Station (ISS), orbiting 400km (250 miles) above Earth. The capsule is scheduled to dock with the ISS on Thursday.
Starliner’s development has been delayed by technical issues, including a significant software error during its first uncrewed test flight in 2019. This error necessitated a second uncrewed test in 2022 to ensure corrections were made. Recently, a minor helium leak in the propulsion system caused concerns, but after consideration, NASA and Boeing proceeded with the launch.
Developed in response to NASA’s call for commercial spacecraft to transport astronauts, Starliner is a shift from NASA owning and operating vehicles to purchasing transport services. This strategy is to save money for NASA’s other ambitions, such as returning humans to the Moon.
NASA awarded contracts to Boeing and SpaceX for these services. While SpaceX completed its crewed flight test in 2020 and has since conducted six operational missions, Boeing’s Starliner is still in its initial crewed test phase. Success in this mission could see the Starliner join SpaceX’s Dragon capsule in routine astronaut transport early next year.
Jim Free, a top NASA official, highlighted the importance of having multiple providers:
“This will give us a second provider, which means if we have a problem with either, we have ways to get our crews to and from the station.”
The Starliner carried about 340kg (760 lbs) of cargo, including a replacement pump for the ISS’s water purification system. Additionally, Boeing included memorabilia such as mission patches, coins, and artwork from children worldwide to commemorate this significant test flight.
If successful, Wilmore and Williams will return to Earth late next week, with the Starliner designed to land using airbags. Various locations in the U.S. Southwest are being considered for the touchdown, pending local weather conditions. This mission is crucial for Boeing as it could pave the way for its Starliner to be used in subsequent crewed missions to the ISS.
