Two of our best astronauts, best of the best of the best, come back safely and gently.

Scrubbed for today.
Oxygen relief valve reading off nominal.

Thanks for posting reason. Was getting kids ready and into bed. Missed why they scrubbed.

Disappointing

My wife is at Disney and was out waiting for the launch.
Maybe tomorrow.

Was looking forward to the compare/contrast of a Starliner/Atlas 5 vs. Crew Dragon/Falcon 9 launch from Florida's Gulf Coast. Alas, we're out of here tomorrow and will have put more miles between us and Florida then ULA. Sad.

You worried it might get altered by the Boeing Hit Squad....

You worried it might get altered by the Boeing Hit Squad....

Given Boeing's track record...a door might fall off in flight or something....

Starliner launch delayed again. They need to roll the vehicle back into the Integration Building and replace the faulty valve. Now targeting May 17 at the earliest.

Why was this faulty valve not discovered during Shake Down Testing?

 

[OverTheTop]

It might not have been faulty, but something in the system made it operate many times and very quickly ("buzz"). It exceeded its certified lifetime.

There are some fluid dynamics with cryogenics that can cause this. I am curious that they haven't seen it before, or if they have it hasn't been dealt with properly.

In one place (I can't recall where) I read that they'd seen this behavior on several Centaurs in the past, including one that acted just like this one did. But this is the first time they've dealt with it with a crew on top of the rocket....so they're being rather more cautious it seems.
