One minute to separation.

End of webcast.

Congratulations to SpaceX and KARI for the successful launch!

Yes, congratulations to SpaceX and KARI!

A fantastic end to an amazing super launch Thursday - 5 successful orbital launches and a crewed suborbital mission.

Congratulations to the entire launch campaign team!

Thank you, Steven Pietrobon, for today's launch thread coverage!

Thank you to the NSF webcast team!

I calculate a non-Sun affected apogee of 1,687,814 km.

Enter initial perigee height (km): 250
Enter SpaceX speed (km/h): 37875
Enter initial orbit inclination (deg): 28.5

Estimated inertial speed = 10945.6 m/s
Estimated apogee height = 1687813.9 km

The Chinese carried out the second launch of the CSSHQ spaceplane in secret, and I should emphasize that the KPLO launch and NROL-199 launch were slightly delayed by a few days, so it is an unexpected coincidence for the five launches to happen in a single day.

When people at Hawthorne go oohhh ahhh for a landing it's almost always because the feed got cut which, as it turns out, it's what happened. They have other feeds but if they don't have signal neither from booster nor droneship you can bet the other feeds ain't working either so they don't see anything at all, wrong or bad, hence the moaning (because just like us, they also like to see the landing)

This is fun conjecturing, psycho-deduction and all

I'm sure the video feed to them and to us is the same feed, and was lost at the same time.
They may have a data feed though that's intuitive to read in real time.

I'm saying thid because I'm pretty tuned in to the oohs and aaahhs during the web casts and I am pretty confident this time around they were very pronounced compared to regular feeds.
Shrug.
I think we've heard all there is to hear about this launch. All's well that ended well.

I'm sure that's true for the "peanut gallery" audio we hear in the background audio from Hawthorne.

However, it's worth pointing out to for the benefit of those less knowledgeable that the loss of video can be due to numerous factors that can interfere with high-rate signals necessary for video, while lower data-rate telemetry continues to come in just fine.

I'm just saying what's basically been the norm for the past 60 successful consecutive landings where the people out there at Hawthorne have gone oohhh ahhh multiple times and speculation has come out from the public saying the booster is dead and then boom, it's there, on the droneship, just fine. Not always that they go oohh ahhh and moaning and such it means something's going wrong... that's my whole point.

I'm in agreement in general, yes.

I was saying that for whatever reason, this one caught my ear. The human mind is a wondrous and confused organ, mine doubly so.

And this happened (to my ear) in real-time, before seeing the off-center landing image, so, hmmm.

Also listen carefully to the narrators before and after loss of signal.

Shrug.

Sure.

But always remember who reads these posts: not everyone is an engineer, or deeply-versed in how telemetry datastreams work. Everything written as an unqualified statement eventually gets picked up and quoted (or worse, just referred to as "I heard ...") without context.

SO: to be abundantly clear to those who don't realize, the audio "Ooohs and Aaaaaahs" are background noise during the webcast. They are not launch controllers nor even anyone in the launch control room. They are just reacting to the lack of video signal.

The controllers on-console may - and perhaps in many case DO - know more than those making noise in the background, and they know more than the launch commenter, at least until that person has time to look at internal data or hear comms we - the audience - cannot.
