An issue with a topping valve is currently being reported by the propellant lead. The valve is not responding to commands. An anomaly team has been summoned to investigate. #DeltaIVHeavy #ULA
And the valve has now started to respond. 🤷‍♂️
Update: Original problem is reported to be well understood and is resolved. This is no longer an issue.

SpaceX is finally making a foray into the Earth observation market as part of a new service for government customers called Starshield. Starshield also includes global comms and hosted payload opportunities. Essentially, Starlink for national security.

I think SpaceX has a huge advantage over existing providers for a few reasons, which is why I think it is a very big development.
- Tremendous bandwidth
- Continuous ground station links via space lasers
- Potential for far more satellites
You can imagine a world where the pentagon says they want a photo of a particular place on Earth, and they get that photo in under a minute, or even near-constant real-time surveillance of a location.

This sounds like what you say when something is getting canceled but you don't want to admit it.
VSS Imagine was unveiled in March, 2021. At the time, Virgin Galactic said that glide test flights would begin that summer. It still has not flown and is now postponed indefinitely, if not canceled.

If you have not already, read Test Gods. It is pretty enlightening on many topics, including how Virgin Galactics marketing department is completely detached from engineering realities.

ULA teams have worked a few minor technical issues that have led to a slight delay in the launch time for NROL-91. A forward plan has become agreed upon and pressing ahead with a launch at 3:25:30 pm PDT.
New issue. A cycle of a fill and drain valve just failed. Taking it to the anomaly net.
Passed on second attempt!

I do not think the SpaceX commentator was reading from the right script there. Deployment is supposed to be at T+15:32 with no second stage restart.
I guess the problem with too many Starlink launches is copy and paste errors.
Are they going to come back for deployment? Or did they update the mission profile and she read the right thing? SpaceX website and the on-screen graphic are both synced for T+15:32.
