Revised spacecraft Starliner's landing date brought forward unexpectedly.
In a surprising turn of events, NASA astronauts Butch Wilmore and Suni Williams, along with their colleagues Roscosmos cosmonaut Aleksandr Gorbunov, will be returning to Earth earlier than expected. The astronauts were initially scheduled to return aboard Boeing's Starliner spacecraft following its first crewed flight in June 2024, but due to significant technical problems experienced during the mission, NASA has arranged for their return on a SpaceX Dragon capsule instead[1][5].
The Boeing Starliner, which brought the initial crew (Crew-8) to the International Space Station (ISS), had issues with its propulsion and helium systems, raising safety concerns about flying the spacecraft back with crew onboard[1]. As a result, NASA and Boeing have been addressing critical issues, particularly with temperature-sensitive oxidizer valves affected by propulsion system thrusters[2][3][4].
This decision to use the SpaceX Dragon for the astronauts' return extends their stay on the ISS to over nine months. The Starliner's technical problems have delayed any further crewed flights until at least late 2026, with an uncrewed cargo mission anticipated first to test improvements[3][4].
Meanwhile, SpaceX continues its regular operations, preparing for its 19th human spaceflight with the Dragon capsule, confidently supporting crew rotations to the ISS[2]. This reliance on SpaceX for crew return highlights an interim gap in Starliner's operational readiness and NASA's cautious approach to spacecraft safety.
The new crew, consisting of NASA astronauts Anne McClain and Nichole Ayers, Japan Aerospace Exploration Agency astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov, is set to replace the outgoing crew. This will be the first space mission for all four astronauts[6].
Suni Williams, who has remained resilient during her extended stay on the ISS, has made history by setting a new record for the most nonconsecutive hours of spacewalking by a female astronaut[7]. As the world eagerly awaits the safe homecoming of these astronauts and cosmonauts, Williams and her fellow astronauts will be departing the ISS aboard a SpaceX Dragon capsule[8].
