The US space agency ended months of speculation about the next flight of Boeing’s Starliner spacecraft, confirming that the vehicle will carry only cargo to the International Space Station.
NASA and Boeing are now targeting no earlier than April 2026 to fly the uncrewed Starliner-1 mission, the space agency said. Launching by next April will require completion of rigorous test, certification, and mission readiness activities, NASA added in a statement.
“NASA and Boeing are continuing to rigorously test the Starliner propulsion system in preparation for two potential flights next year,” said Steve Stich, manager of NASA’s Commercial Crew Program, in a statement.
Reducing Crewed Missions
NASA also said it has reached an agreement with Boeing to modify the Commercial Crew contract, signed in 2014, that called for six crewed flights to the space station following certification of the spacecraft. Now the plan is to fly Starliner-1 carrying cargo and then up to three additional missions before the space station is retired.
“This modification allows NASA and Boeing to focus on safely certifying the system in 2026, execute Starliner’s first crew rotation when ready, and align our ongoing flight planning for future Starliner missions based on station’s operational needs through 2030,” Stich said.
SpaceX and Boeing were both awarded contracts in 2014 to develop crewed spacecraft and fly six operational missions to the space station. SpaceX, with its Crew Dragon vehicle, flew a successful crew test flight in mid-2020 and its first operational mission before the end of that year. Most recently, the Crew-11 mission launched in August, with Crew-12 presently scheduled for February 15.
Dragon has served as a reliable transport system for NASA as Boeing has faced development struggles.
Starliner’s first flight in December 2019, without crew, had to be truncated after software problems plagued the vehicle. It was nearly lost shortly after launch as well as before atmospheric reentry. It did not make a planned rendezvous with the space station.
The second mission, Orbital Flight Test 2, took place in May 2022. Because of problems on the previous mission, this spacecraft also flew uncrewed. This flight was more successful, reaching the space station despite some thruster issues.
