NASA's Crucial Decision: Starliner vs. SpaceX

NASA is deliberating whether to keep two astronauts at the International Space Station until early next year and return the troubled Boeing Starliner capsule empty. The decision hinges on solving thruster issues, and NASA may opt to use SpaceX for the astronauts' return, causing adjustments in crew assignments.

NASA is currently considering whether to extend the stay of two astronauts at the International Space Station (ISS) until early next year and return the problematic Boeing Starliner capsule empty. The astronauts, Butch Wilmore and Sunita Williams, might instead return on SpaceX's upcoming mission, which would keep them at the ISS until February.

Initially, the test pilots planned a brief week-long mission, but thruster failures and helium leaks have marred the capsule's journey, bringing its ability to safely return into question. NASA officials are analyzing data and expect to decide by next week. The thrusters are essential for maintaining the capsule's position when descending from orbit.

Switching to SpaceX's crew would mean reallocating seats on the next ferry flight scheduled for late September, potentially bumping two astronauts. Additionally, the ISS's limited docking ports would require Boeing's Starliner to leave before the arrival of SpaceX's Dragon capsule. Despite Boeing's assurances that Starliner can safely bring the astronauts home, NASA is keen on ensuring safety and reliability before making a final call.
