NASA's Starliner Spacecraft Docks at ISS Despite Malfunctioning Thrusters

Two NASA astronauts, Butch Wilmore and Sunita Williams, successfully docked Boeing's Starliner spacecraft at the International Space Station (ISS) on June 6, 2024. The docking was delayed due to malfunctioning thrusters.

According to reports from various sources, five of Starliner's reaction thrusters malfunctioned during the approach to the ISS. Three of these thrusters had helium leaks. However, NASA and Boeing engineers were able to recover four of the faulty thrusters and close off the leaks by closing all helium manifolds in the attitude thruster systems.

The Starliner spacecraft lifted off atop a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida on June 3, marking its inaugural crewed test flight to the ISS. If successful, NASA could authorize Boeing to conduct regular flights to the space station for the agency.

The astronauts are expected to spend about a week at the ISS before returning to Earth in Starliner on June 14. However, the landing date could change as the mission progresses.

Flight controllers will continue to monitor Starliner's reaction control thrusters, which were able to recover all but one during various tests during the docking process.
