The Boeing Starliner capsule, which encountered major technical issues during its first crewed flight in 2024, has been reintegrated into NASA's plans for future crewed missions. Initially intended as a ten-day mission, the flight was extended to nine months due to helium leaks and problems with the propulsion system. These issues forced NASA to rely on SpaceX to bring the two astronauts aboard the Starliner back to Earth. In February of last year, NASA officially labeled the incident a "Type A accident," a classification that includes major failures such as loss of control or human lives, similar to past disasters like the Challenger and Columbia shuttle accidents. NASA Administrator Jared Isaacman announced during a press conference on September 28 that the agency still plans to use Starliner as a second crewed vehicle for astronauts, alongside SpaceX's Crew Dragon. NASA has identified the causes of the failures, including damaged valve joints from exposure to nitrogen tetroxide and corrosion in the thrusters caused by residues of hydrazine reacting with CO₂ in the air. Boeing will address these issues by removing the harmful residues and isolating the thrusters as part of necessary modifications. An unmanned Starliner-1 mission is scheduled to test these changes, possibly in December 2026 or January 2027. If successful, the next crewed mission, Starliner-2, is planned for mid-2028, with astronaut Woody Hoburg on board, followed by two more crewed flights. NASA will provide Boeing with $359 million to fund the capsule's modifications and to certify the Vulcan rocket from United Launch Alliance (ULA) for crewed missions. This is necessary because the Atlas V rocket, which will launch Starliner until its fourth mission, is being retired. Despite a July report from NASA's internal inspection office that criticized the agency for over-reliance on Boeing and insufficient testing of the capsule, NASA continues with the Starliner program. The need for a second crewed vehicle remains urgent, especially as the International Space Station (ISS) is expected to remain operational until 2030. NASA also hopes to use Starliner for future commercial space stations. Boeing has invested $2 billion in the program and expressed enthusiasm about the capsule's return to service.
