Boeing Starliner will not launch before Friday, May 10, and it may push into next week. The issue is a valve that controls liquid oxygen pressure on the upper stage of the rocket. It was humming/oscillating, and they need to examine it to see if it needs to be replaced.

If it doesn't, launch will be no earlier than Friday. If it does need to be replaced (which means the rocket needs to be rolled back), we're likely looking at launch dates into next week.

@skrishna have you ever talked or heard anything about the astronauts that got spacex selection vs ones that got starliner? I remember when both projects had that initial conference/announcement and all crews were excited to go. Did anyone from Boeing assignment ever get to switch to spacex ride?
@laimis Yes, but for a launch like this it's really important that the crew train on the vehicle and know it inside and out, so it's not so much about getting to switch to fly sooner. That being said, Jeanette Epps was briefly assigned to this flight and is currently on the ISS as part of SpaceX's Crew-8.
@skrishna yup yup, by no means for this one. Good to hear that some of the starliner assignees were able to switch.
