The Boeing Starliner mission has encountered numerous challenges, raising significant safety concerns for astronauts such as Sunita Williams. NASA has expressed fears of potential "catastrophic failure" related to the spacecraft's integration with the International Space Station (ISS). This apprehension stems from a series of setbacks and problems that have plagued the Starliner mission, causing delays and putting the safety of crew members at risk.

Recently, astronauts intended to operate the Starliner found themselves stranded and faced alarming conditions, as highlighted by repeated news updates. These issues forced Boeing to bring the beleaguered Starliner capsule back to Earth without its astronaut team, further compounding the project's difficulties.

Despite hopes for a successful mission, the setbacks have kept astronauts, like Sunita Williams, from completing their planned tasks, raising critical questions about the vehicle's viability and safety. NASA's concerns underscore the ongoing obstacles preventing the Starliner from meeting its goals and ensuring astronaut safety on future missions.
