NASA assures public that astronauts onboard Boeing's ISS mission are not in a state of being stranded.
In the realm of space exploration, the Boeing Starliner mission to the International Space Station (ISS) is facing significant challenges. The mission, initially scheduled for late 2024, is now delayed, with the next crewed flight anticipated in late 2026 [1].
The primary cause of these delays is a technical issue with the spacecraft's oxidizer valve temperature controls [1]. NASA and Boeing are working tirelessly to resolve these problems, and they may be preceded by an unmanned cargo flight to demonstrate the necessary fixes [1].
Meanwhile, the astronauts Barry "Butch" Wilmore and Sunita "Suni" Williams, who were originally scheduled for a short stay of over a week in the flying laboratory, found their mission extended. Their return to Earth was delayed due to NASA's decision to launch SpaceX Crew-9 with just two astronauts in September 2024 for safety reasons, which affected crew rotation and transfer schedules between Starliner and Dragon vehicles [2]. Consequently, Wilmore and Williams returned to Earth aboard a SpaceX Dragon capsule in March 2025, rather than on Starliner or earlier [2].
Despite the delays and ongoing investigations, it's important to note that the astronauts are not in danger and are not stuck on the ISS. Mark Nappi, senior manager at Boeing, has emphasised this fact [3]. Furthermore, the Starliner spacecraft still has enough helium for a return, according to NASA [4].
However, another anomaly has been identified in the Starliner spacecraft, in addition to the thrusters issue [5]. NASA and Boeing are still investigating the cause of the helium leaks in the spacecraft [6]. Ground tests are being conducted on similar thrusters to investigate the problem experienced by the Starliner spacecraft [7].
The Starliner mission, ordered by NASA 10 years ago to serve as a space taxi, is running behind schedule by years [8]. This mission is crucial for the Starliner spacecraft to demonstrate its safety and reliability for future operations.
While SpaceX has been successfully transporting NASA astronauts to the ISS for four years, the Starliner mission is yet to make its mark. The successful completion of this mission is necessary for the Starliner capsule to obtain NASA certification and potentially be involved in future missions [9]. However, the possibility of SpaceX's involvement in future missions is seen as potentially disrespectful and problematic, given the current situation [10].
