Astronauts stranded on the International Space Station due to Boeing's difficulties; returning via SpaceX seen as a humiliating blow, potential disaster for Boeing
In an unexpected turn of events, Boeing's Starliner spacecraft, designed to carry astronauts to the International Space Station (ISS), has encountered a series of issues. The primary concern is a leak of helium, an inert gas used in the Starliner's propulsion valves.
The root cause of the problem appears to be a faulty seal in a flange connecting the propellant lines to the reaction control system thrusters. This defective rubber seal has allowed helium to escape through tiny imperfections, causing significant concerns. Additionally, there have been overheating issues with some thrusters, which require hardware modifications to prevent recurrence.
These issues have had a substantial impact on the Starliner's operational flights. The initial crewed return mission, scheduled for 2024, has been cancelled due to the risks posed by the leaks. The Starliner's docking time at the ISS is 45 days, but these delays have added operational risk, prompting NASA to consider contingency plans such as a potential rescue mission using SpaceX’s Dragon capsule.
The leaks occurred in the thrusters used for maneuvering and braking, and the engineers are unsure whether the problem could worsen during future flights. If the leaks cannot be resolved while the Starliner is connected to the ISS, the affected part will burn up during re-entry.
NASA is currently analysing data to find the source of the leaks in the Starliner's propulsion system. The arrival of the first astronauts at the ISS using the Boeing Starliner spacecraft was marked by technical difficulties.
There are concerns about whether Boeing was too optimistic about the leaks or if it's a general project management issue. Four whistleblowers have warned of "serious" safety problems on Boeing planes, adding to the scrutiny.
Professor Rauw has expressed concern about Boeing's image if they were to rely on SpaceX for the return of the astronauts. The next Starliner flight has been delayed until 2026, with the decision pending on whether this will be a cargo or crewed mission.
Progress with new sealant and hardware improvements are promising but require thorough validation before the Starliner resumes crewed flights. NASA official Steve Stich stated that they are letting data guide their decision-making regarding the management of small helium system leaks and thruster performance.
In a separate development, a mysterious moon named Amalthea has been spotted in front of Jupiter's Great Red Spot. This new topic is unrelated to the Starliner incident but adds another intriguing chapter to the exploration of our solar system.
