Overview
- An approximately 300‑page independent investigation found propulsion hardware failures and qualification gaps compounded by flawed decision‑making and leadership at both Boeing and NASA.
- During rendezvous in June 2024, Starliner suffered helium leaks and multiple RCS thruster failures that caused a temporary loss of six‑degree‑of‑freedom control before docking.
- NASA formally designated the flight a Type A mishap and issued 61 recommendations spanning technical, organizational, and cultural changes.
- Astronauts Butch Wilmore and Suni Williams remained on the ISS for about nine months; Starliner returned uncrewed in September 2024, and the pair came home on a SpaceX Dragon in March 2025.
- NASA and Boeing are continuing ground tests of Starliner thrusters at White Sands, and a cargo‑only Starliner mission to the ISS is planned as soon as April as Boeing reports progress on corrective actions.
