NASA Cuts Boeing Starliner Missions as SpaceX Pulls Ahead

NASA has significantly scaled back Boeing’s Starliner program after years of technical issues and delays, announcing that the next Starliner mission to the International Space Station (ISS) will fly without astronauts. The revised plan reduces the number of contracted Starliner missions and highlights SpaceX’s widening lead in NASA’s Commercial Crew Program.

The decision follows Starliner’s troubled first crewed test flight in 2024, when astronauts Butch Wilmore and Suni Williams experienced multiple thruster failures during the spacecraft’s approach to the ISS. The malfunction left the crew stranded on the station for nine months while NASA and Boeing worked through the propulsion system issues and debated the program’s future.

Originally valued at $4.5 billion, Boeing’s contract under the Commercial Crew Program envisioned six operational astronaut flights. NASA’s latest modification cuts that number to four, including up to three crewed missions and an uncrewed cargo flight set for April 2026. Two additional flights remain optional. With the changes, the contract’s value has dropped by $768 million to $3.732 billion; NASA has already paid $2.2 billion to date.

Despite the setbacks, Boeing maintains its commitment to Starliner, emphasizing that safety remains its top priority as engineers incorporate lessons learned from previous tests. NASA says both teams are “rigorously” testing the spacecraft’s propulsion system in preparation for potential missions next year, with full certification targeted for 2026.

While Boeing struggles to get Starliner on track, SpaceX’s Crew Dragon has become NASA’s primary astronaut transport, conducting regular ISS missions since 2020. The agency has already booked Dragon flights through the station’s planned retirement in 2030, raising doubts about Starliner’s long-term competitiveness.

NASA continues to insist it needs two U.S.-built spacecraft to avoid sole reliance on Russia’s Soyuz capsules. Boeing still envisions a commercial future for Starliner on private space stations, though such opportunities remain years away.
