Per an official at Vandenberg Air Force Base, the launch of Firefly's Alpha rocket has been postponed "indefinitely." No reason given.

Eric, Firefly’s launch is not 'postponed indefinitely'. Firefly received our FAA launch license on Monday, is in final integrated vehicle to pad testing, and is preparing to perform the our pre-launch static fire soon.”

Another tweet, this ones from John Kraus, and seems to show an email from Vandenburg's media manager.

Looks like either Firefly management didn't bother to update their media people on the change, or the Air Force updates the media on developments before it's partners.

The original email actually makes this sound like a simple rescheduling, whereas when Eric Berger took the phrasing "postponed indefinitely" out of that context in his original tweet, it sounds much worse. I'm sure that was unintentional for the record.

Overall, seems like a mess all around.
Wait, ∆V? This site will accept the ∆ symbol? How many times have I written out the word "delta" for no reason?

Speaking of Eric Berger tweets, I wonder if this one may give a hint as to what's delaying the Firefly launch:

Downside of shared launch site but cheaper than building one from scratch.

SLC-2W and SLC-6 really aren't shared in any significant sense aside from technically existing on VAFB property. They're a full 12 miles apart.

I doubt there is any connection here. The pads are very distant, and the Delta IV-H would launch first anyway.

How far away are SLC-3W and SLC-4E? I was thinking of how a Titan IV launch from the latter indefinitely delayed SpaceX's plans to launch Falcon 1 from the former. But perhaps those two are much closer than the Firefly Alpha and Delta IV pads are to each other.

~1.2 miles, 10X closer.

Apparently now scheduled for mid-June.

About the problems behind the delay, from the article:
Quote
Markusic said that Firefly “ran into some problems with readiness of the launch site” at Vandenberg Air Force Base in California, and also had a significant delay from a supplier of the rocket’s flight termination system – a key piece required for the rocket to launch.

“Just from our side, we did not get the launch site ready as quickly as we thought we could. We kind of miscalculated on where we were in readiness and that’s on us. This is something we didn’t do well,” Markusic said.

The CEO added that Firefly hopes to launch Alpha by mid-June, but emphasized that an inaugural launch comes with “a lot of unknowns.”

...Is Firefly sourcing their AFTS from Rocket Lab?  Peter Beck has said they intend to make their AFTS available to other companies, and the significant delay matches up with Rocket Lab's public comments about their delay, but I would be surprised to find out they already have a customer.
Could I interest you in some clean burning sub-cooled propalox and propalox accessories?

Rocket Lab isn't building its own AFTS, it's acquiring it from a NASA contractor and NASA's certification is what's been delaying Electron's Wallops debut and (in part) Alpha's first flight.

Once this AFTS is sorted it will be available to all LVs.

Yesterday Firefly performed a static fire test of the Alpha launch vehicle on its Vandenberg launch pad. The fully-fueled, flight-ready vehicle fired its first stage engines for fifteen seconds.

The test was successful and clears the way for Firefly to make its first launch attempt, currently scheduled for September 2.

All the best for maiden launch.

Anyone have an idea on why the green, characteristically TEA-TEB looking flash was also seen at engine shutdown?

Some kind of engine purge or some unintended engine rich combustion instead?

Firefly uses a TEA-TEB canister with burst disks, so it could be that they decided to deplete the canister at the end to make swapping it out with a fresh one an easier/safer/cleaner operation.

If not that, engine-rich shutdown is usually the case.
