As astronauts Butch Wilmore and Suni Williams near their return from the ISS, NASA and Boeing test the Starliner’s propulsion system using a new thruster at White Sands. A readiness review this month will set a new return date, with mission updates provided by NASA and Boeing leadership.

NASA and Boeing continue working to increase their understanding of the Starliner spacecraft’s propulsion system before the return of agency astronauts Butch Wilmore and Suni Williams to Earth from the International Space Station. Teams are conducting ground tests at the agency’s White Sands Test Facility in New Mexico using a new Reaction Control System thruster previously planned for use on a future Starliner flight.
