Before I steer people in my neighborhood wrong, am I correct in thinking there should be an excellent sighting opportunity in the central United States about 90 minutes after launch (i.e., around 10:00pm local time?)

Check heavens-above.com for your location to confirm passes. They have a placeholder for L7 on their homepage. For southern MN the first visible evening pass is tomorrow night at 10:08 PM.

Thanks! I didn't expect they'd have sighting opportunities prepared before launch.
West Texas does have a sighting opportunity from 10:00 to 10:01 tonight.

SpaceX has been providing prelaunch supplemental TLEs to tracking sites so they can calculate passes even before launch. It’s pretty awesome that all parties are working together to provide pass data ahead of launch. Having seen the Starlink train after the last launch it is really quite a spectacular sight to see.

There's a fun side-effect of those pre-published TLEs... Here in Central Florida, we'll have the chance to see the train of satellites rise above the southwest horizon a mere 150 seconds after launch! ???

I might have missed it, but did they say if these fairing halves are used?

Another one on the deck... amazing :)

Edit... had to attach pics of landing since it was cloudy here and I couldn't see liftoff :|

And the drone ship feed did NOT cut out at all. Very smooth during the whole landing burn.

Wonder what they've been wanting to hide for so long? Glad they did show it though.

Great video on this launch and landing.  Guessing JRTI had its system upgraded on the referb.

Best launch video

Maybe the fact that they produces space debris by jetisoning the clamp?

WOW. They actually showed the deployment this time :-) So fascinating :)

I wonder if the fact that OneWeb as the main competitor has gone bankrupt has anything to do with it. Probably not, they never had the architecture to even try and adapt to this. Blue Origin possibly could, if Kuiper eventually becomes reality, but then again by the looks of it Starlink will probably be on-line and serve customers before Blue Origin makes their first successful orbital launch.

I think, when your technological lead has become far enough that even a fast follower would take years to get to where you are now, you can show your tricks safely, knowing that by the time someone could duplicate them, you wont need them anymore.

Specifically in this case, by the time Kuiper sats could benefit from a bulk deployer on top of New Shepperd Glenn SpaceX would already shovel them out of Starships cargo hold in bulk quantities with an entirely different method.

If this deployer has been compared to a dump truck dumping its load versus individual offloading of palettes, then what Starship might be doing could be closer to pressure pumping concrete through a construction pipeline...

Stage and sats just passed nearly overhead here. Clearly visible through dispersing remnants of rain clouds.

I must admit, I briefly considered the "hey Oneweb just went bankrupt" angle as well, but I'll stick with "unexpected interference due to shock/moving metal that they've only just worked around" for now.
All aboard the HSF hype train!  Choo Choo!

Apropos working around RF interference - they also managed uninterrupted landing coverage from JRTI - after it has just been refitted extensively. I hope that wasn't a fluke but points to a more robust architecture.

After all SpaceX IS deploying a global communication network at this very time, if there's one thing they should be able to deliver, then it's uninterrupted coverage from anywhere in the world ;)

At this point it might even be possible that the new droneship has an experimental Starlink transceiver.

But F9 probably would need new FCC documents to do so - unless Starlinks just happen to be able to receive and relay F9 telemetry ;)

Watching how relatively quickly the deployment rods decay and reenter, that idea never really made sense to me, but whatever reason (technical, procedural, or managerial) we finally got to see the deployment, I'm stoked.  Now I'm trying to work out how the deployment is actuated.  (Watching it repeatedly, you can see the deployment rods "slacken" before swinging out and releasing.)
