Boeing and NASA Advance Starliner Program with Contract Modifications

Boeing and NASA are pushing forward with their Starliner program, modifying the contract to support human spaceflight certification and prepare for long-term crewed missions in low Earth orbit. The uncrewed Starliner-1 mission is still on track to launch in December 2026 or January 2027, delivering essential cargo to the International Space Station (ISS) while ensuring the highest standards of safety and reliability.

The contract modification includes several key upgrades, such as replacing valves on the crew module reaction control system thrusters and adding measures to prevent corrosion. Boeing has also completed corrective actions for the technical issues identified during the Crew Flight Test in 2024, with plans to close out all remaining validation work in preparation for the Starliner-1 launch.

'With safety-first as their guide, Boeing and NASA teammates worked together over the last two years to address the issues encountered during the crew flight test,' said John Mulholland, vice president of the Starliner program. 'We're grateful for NASA's partnership, and we are confident the Starliner vehicle will be ready for flight.'
