NASA Accelerates Boeing Starliner Revamp After 2024 Crew-Flight Mishap

The Path Forward for Starliner
NASA announced in late September 2026 that it will fund an additional $359 million to address the technical problems that halted Boeing’s crewed Starliner flight in 2024. The agency plans an uncrewed test flight—Starliner-1—targeted for December 2026, followed by the first crewed mission—Starliner-2—scheduled for mid-2028. Astronaut Woody Hoburg will command the crewed flight.
Background & Context
The Crew Flight Test (CFT) launched in June 2024 with NASA astronauts Butch Wilmore and Suni Williams aboard. Helium leaks and failures of five of the 28 reaction-control-system (RCS) thrusters forced NASA to return the capsule uncrewed. The astronauts remained on the International Space Station for nine months, returning on a SpaceX Crew Dragon in March 2025. NASA classified the incident as a “Type A mishap,” its most severe safety rating.
Timeline
- June 5 2024 – Starliner lifts off on an Atlas V rocket.
- Late September 2026 – NASA and Boeing brief the press on upgraded hardware and funding.
- December 2026 (target) – Uncrewed Starliner-1 flight to the ISS.
- Mid-2028 (target) – Crewed Starliner-2 mission.
Data & Statistics
- $359 million allocated for spacecraft upgrades and Vulcan Centaur certification.
- 28 RCS thrusters; 5 failed during CFT.
- Helium leak traced to valve degradation after exposure to nitrogen tetroxide.
- Future Starliner flights will use United Launch Alliance’s Vulcan Centaur, which still requires crew-flight certification.
Official Statements & Responses
NASA Administrator Jared Isaacman emphasized the agency’s commitment to a “multiple-provider” crew-transport capability, noting that Starliner-1 will validate the redesigns before crew return.
NASA’s Low-Earth-Orbit Program manager Dana Weigel said the helium-leak issue was solved by replacing seals with a new material and tighter tolerances, and that the thruster anomaly was linked to corrosion from residual hydrazine combined with atmospheric carbon dioxide. New procedures will flush and purge thrusters to prevent recurrence.
Boeing’s program leadership confirmed that the upgraded Starliner-1 will incorporate new crew-module thrusters, batteries, and parachute refinements, and that Vulcan certification work will be jointly funded by NASA.
Verbatim Quotes
- “That is why the material of the seal was changed,” — Dana Weigel
- “We determined that the crew module thruster anomaly is the result of corrosion,” — Dana Weigel
- “We are starting with an uncrewed Starliner-1 mission to the International Space Station to validate the improvements made to the spacecraft and gather the flight data we need,” — Jared Isaacman
- “Starliner-1 is going to be a key step forward in that development effort to get back to crewed flight,” — Woody Hoburg
Why It Matters
The Starliner program preserves a U.S.-based, dual-provider crew-transport system for the ISS and future commercial orbital destinations. With SpaceX’s Crew Dragon currently the sole operational capsule, Starliner’s return would restore redundancy and support the planned de-orbit of the ISS by 2031.
What’s Next
- December 2026 – Launch of the uncrewed Starliner-1 mission to gather performance data and validate upgrades.
- Post-flight – Completion of the thruster-valve redesign and certification of the Vulcan Centaur for crewed launches.
- Mid-2028 – Crewed Starliner-2 flight, marking the first astronaut return to the capsule.
- Beyond 2028 – NASA plans to purchase at least one crewed LEO mission every six months into the 2030s, potentially expanding Starliner’s operational cadence.
