I know it's a white star and next to a US flag but wow that picture has a Red Square May Day parade vibe to it.  I think the stepped diameter rocket makes me think missile :D

I hear ya.  I've never been able to help but look at Astra's rocket and think that it really looks like it should be coming out of a hardened silo.

Considering there is a potential launch tomorrow, nothing whatsoever to talk about, no one hyped or anything, and most importantly not even the Astra director or marketing person? Never seen a company with so little to say :-\

Sounds like the start of the launch window has been moved to November 5th:

We’re proud of our team for getting us back to the pad in 60 days. After the team & LV0007 arrived in Kodiak, we learned planned range improvements would not finish in time to complete the necessary preparations for a launch in 1st segment of our window. Stay tuned. #AdAstra

Updated notice from Pacific Spaceport Complex Alaska:

Quote from: PSCA
Pacific Spaceport Complex Alaska (PSCA) will be conducting a launch from Launch Pad LP-3B at Narrow Cape, Kodiak, Alaska, with a launch azimuth of 172°. Daily launch operations are scheduled between 0400-0730 UTC which is 2000-2330 Alaska Time on November 5th through November 12th, 2021. Mariners are requested to remain clear of the Hazard Areas during the scheduled launch operations.

Note: On Sunday, November 7, Alaska will change from AKDT to AKST, so beginning on Monday morning UTC, Sunday evening AKST, the local time will be 1900-2230.

Per the FAA TFRs, here's clarification about the time change from AKDT to AKST.  Local time is staying the same and the UTC time is changing.

This also clarifies that the dates in the PSCA notice are relative to local time, not UTC.

Saturday, November 6 - Sunday, November 7 at 04:00-07:30 UTC (Friday - Saturday at 20:00-23:30 AKDT).
Monday, November 8 - Saturday, November 13 at 05:00-08:30 UTC (Sunday - Friday at 20:00-23:30 AKST).

Here's an updated notice from the PSCA.  It does NOT include the new delay reflected in the tweet posted above, but it does provide clarification of the dates being local and adds two more launch days.

Quote from: PSCA
Pacific Spaceport Complex Alaska (PSCA) will be conducting a launch from Launch Pad LP-3B at Narrow Cape, Kodiak, Alaska, with a launch azimuth of 172°. Daily launch operations are scheduled between 0400-0730 UTC which is 2000-2330 Alaska Time on November 05th through November 07th, 2021 (local). Daily launch operations are scheduled between 0500-0830 UTC which is 2000-2330 Alaska Time on November 08th through November 14th, 2021 (local). Daily launch operations are scheduled between 0500-0830 UTC which is 2000-2330 Alaska Time on November 18th through November 19th, 2021 (local). Mariners are requested to remain clear of the Hazard Areas during the scheduled launch operations.

Here's my interpretation of the current schedule:

Tuesday, November 9 - Monday, November 15 at 05:00-08:30 UTC (Monday - Sunday at 20:00-23:30 AKST).
Friday, November 19 - Saturday, November 20 at 05:00-08:30 UTC (Thursday - Friday at 20:00-23:30 AKST).

Noticed the launch date changed again. Is this a viable long term launch location being what the weather can be like in Kodiak, or anywhere in the northern areas? If you were a customer, it doesn't seem a reliable place to count on your load being delivered on time.

What makes you think it’s the weather? They’ve been trying to static fire for like a week now.

Most launch sites are a compromise between, orbit access, weather, airtraffic and access.
With RLVs downrange recovery sea conditions will add another constraint.

Theoretically, their mobile launch system makes it easy to launch from other sites. I suspect the paperwork necessary to get approval to launch from more crowded sites is not inconsiderable (and those sites might want to see a track record of successful launches, given Astra's past attempts), but at least it wouldn't require building substantively new hardware.

The same FAA TFR for November 18/19 and November 19/20 remains in effect.

There is a marine notice from the USCG, but I haven't seen anything from the NGA, which is surprising if Astra is going to actually make an attempt tonight.

It's a cold day in Alaska, and the upper stage umbilical looked very icy. They zoomed in on it just before they went to stock video.

Maybe they need to scrub and insulate some lines better. (The issue might be something completely different, of course.)

If the flight goes off successfully, it does help prove the launch envelope.

Still in the hold.
Today's window is 05:00 to 08:30 UTC.  So, they need to emerge from the hold before or at 08:00 UTC today.

Tomorrow's window also 05:00 to 08:30 UTC.

From the webcast:
Launches from Kodiak share airspace with airplane flights to and from Anchorage.

The dates and times of launch windows are constrainted by the  FAA because the increased rate of passenger and freight flights due to Thanksgiving (stated as "the holidays" in the webcast). Thus, no launch window on Nov 21 UTC, etc.

IIRC, Anchorage can be a midpoint for transpolar flights, as well as a destination.

We live in the age of (jet) airplanes, even in Alaska!

Before the hold I heard them say 6:04:00, so I imagine it was on the dot at 6:16:00.

Congratulations Astra!!

A new small satellite launcher has made orbit. And it’s supposed to be capable of responsive launch from multiple sites on short notice. I could see the DoD making use of this.

~6 person setup/on-site launch team and everything containerized really helps for making that possible too
I think they said their „Red Team“ on site is only 4 people. And they transported the team, the rocket and the ground equipment all on the same C-17.

In the terminal count, there was an interesting callout from the LD to the FSO, advising them to prepare to issue an 'option command' at T+164 (2m 44s into flight) calling out "an event". Going by the timeline that's just prior to MECO. AFTS is not armed and instead in shadow mode (FSO would not be inhibiting an on-board system, the FTS is fired by ground command) so something to listen out for on the next attempt.
Well, that turned out to be an opaque 'option enabled' callout.

Before the hold I heard them say 6:04:00, so I imagine it was on the dot at 6:16:00.

It is indeed a 6 person team, but it was neat that they could transport all on a C-17, including that team

Somehow I thought I heard seven? Red lead, four engineers, one IT person, one safety person. Obviously, that doesn't change the "capable of transporting on a single C-17" calculus.

If you're thinking of the RSO, they're range-side so not technically part of the Astra team.

I went back to the livestream (at around 48:43 in the video), and here's an index of everyone listed as being on the Red Team, along with roles:

Red Lead:
Adam Fritsch

Pad Technicians:
Hill Hudson
Robert Freeman
Eric Larsen
Sam Heershap(?) (I couldn't find this person on LinkedIn to verify the spelling of their last name)

Red Wire (IT):
Eric Steinberg

Safety Lead:
Ryan Hirschfield

It didn't sound like Ryan is also the RSO (Ryan's role was described as "responsible for the safety of overall launch operation events, including personnel compliance with our safety policies and procedures"), but I could be wrong about that.

Pretty sure the pressure fed Aether engine on the second stage has no restart capability so it will have to demise naturally

From the webcast:

the upper stage will

once it reaches orbit will

be deorbited and burn up in the

atmosphere so we do

consider it very important to be

responsible stewards of space we do not

want to leave any space debris up there

So if there is only natural decay that is misleading

Yeah, very curious about deorbit. I heard some pretty sketchy answers on stream which I had trouble believing. I kind of doubt any early space startup has the bandwidth to spend time/mass on developing restart on a S2 this small when they just barely made it to orbit

Agreed. Also a bit upset that the orbit was so high, especially if there is no restart (which I strongly suspect will be the case). Couldn't they show that it could get to orbit but not stay in orbit by going into a highly elliptical orbit which could deorbit much sooner? Or is that difficult from a performance perspective?

The US has restart capability. Being pressure fed doesn't change that. They need it for reaching or circularizing high orbits anyway. They went for direct insertion this time to reduce risk.

The gossip is that they did insert in 500km circular orbit and the 438 perigee was due to a deliberate second burn. It's not clear to me why it was not a full deorbit burn. I haven't heard if that was also deliberate or an incomplete burn. It'd be nice if they said something about that publicly because that 438 just doesn't sound nice.

Here is a plot of the LV-0007 mission telemetry.

The webcast provided data updates once every three seconds, so the acceleration has a rather stepped appearance compared to webcasts with more frequent updates.

It may not be entirely Astra's choice.  They had a customer for this mission, which stayed attached to the second stage, meaning if they deorbit the second stage, the payload is lost as well.  The customer may want more time in orbit, or a particular orbit.

My understanding was that the customer's main goal for this payload was "characterize the launch environment of Rocket 3, so we know what we're buying for future launches." Sticking around in orbit after simulated payload deploy doesn't help with that, and if anything characterizing the deorbit properties would probably be preferred.

The first stage acceleration peaks quite high, at about 8G.  Are smallsats usually rated for this, or will Astra have to throttle down (as most providers do) on commercial missions?  Is there a payload user manual?

I think during the webcast some mention was made of "lucky number seven," so they could lean in that direction.

So just a follow-up... doesn't look like Astra S2 has come even close to doing anything remotely close to intentional deorbiting? I have serious questions about whether or not they could have had the performance to seriously deorbit the stage, or maybe restarts failed? I don't have any issues with the reality that an early launch is unlikely to have the performance available to deorbit the stage, but I do when they claim that they're going to when they really can't.

NORAD 49494 - ASTRA DUMMY MASS is still at 507 x 443 km.
