The first crewed launch of Boeing's troubled Starliner spacecraft has been delayed again, to May 25, this time because of a helium leak in the service module.
NASA had set the liftoff for May 21 after scrubbing a May 6 launch but the helium leak was discovered on Wednesday. While the agency said the leak in the craft's thruster system was stable and wouldn't pose a risk during the flight, "Boeing teams are working to develop operational procedures to ensure the system retains sufficient performance capability and appropriate redundancy during the flight."
