Boeing stated Friday that its Starliner spacecraft shall be grounded indefinitely whereas it continues to research issues with the valves within the propulsion system.

Within the 10 days since Boeing and NASA scrubbed the launch in Florida, technicians and engineers have sought to open 13 valves that management the circulate of dinitrogen tetroxide (NTO) oxidizer by way of the service module of the spacecraft. There are 24 oxidizer valves within the propulsion system, which is essential each for in-space journey in addition to launch emergency escapes.

Boeing has been capable of open 9 of the valves, stated John Vollmer, vice chairman and program supervisor of Boeing’s Industrial Crew Program. The opposite 4 stay caught.
