There seems to be only one webcast as with NROL-76, guess this means separate technical webcasts have been retired.

Maybe viewing figures compared to the hosted webcast have been reeeeaaally low. Anyone know?

And how do you determine it's a different second stage, what kind of upgrades?

The exterior of this stage and the NROL 76 stage both have/had different appearances than previous stages. One or two exterior conduits have been removed or relocated, for example. The NROL 76 stage performed a long coast experiment before restarting, which is the expected upgrade for some future EELV missions. There may be other, hidden improvements.

You may see numbers yourself: https://www.youtube.com/user/spacexchannel/videos
Number of people watched technical webcast is 3-5 times smaller than for hosted one, but in hundreds of thousands nonetheless.

Perhaps it just depends on the specific launch. Last time it was a classified mission so we only had the first stage to watch anyway after a certain point and this time there is no landing to watch so perhaps they decided one feed was enough.

It could also have been for an abundance of caution in terms of giving information on speeds etc.

Go Searcher remains in port. Fairing recovery attempt doesn't look likely. https://www.marinetraffic.com/en/ais/details/ships/shipid:426008/mmsi:366584000/vessel:GO%20SEARCHER

Marine traffic had it wrong last launch (They said it was in port... ship not in port).

For a second I was hopeful they would keep showing the first stage until the feed died.

Sounds like SpaceX people getting some good S1 views?

wannamoonbase · « **Reply #169 on:** 05/15/2017 11:29 pm »

From the staff sounds at about 7:30 I wonder if they were watching a fairing experimental recovery.

I get the feeling the staff are seeing some interesting stuff judging by the background noise!

I think the Spx folks were watching the S1 reentry when they were cheering. Bummer they pulled that feed from the view early I wanted to see S1 tumble in.

matthewkantar · « **Reply #173 on:** 05/15/2017 11:31 pm »

At around 7:10 into the launch there was a lot of noise from the crowd, think they could still see the first stage, or fairing cam streaming?

Yep, thinking the same thing. I bet they got some interesting views of stage 1 entry (and possibly breakup?)

Sounded awful. Whooooa! Ohhhhh nooooooooooo!

ZachS09 · « **Reply #176 on:** 05/15/2017 11:33 pm »

Let me tell you this: I was not watching the webcast when the crowd was moaning about the first stage LOS. I did not know what was happening at first; I thought the second stage suffered an anomaly until I heard the callout.

TrueBlueWitt · « **Reply #177 on:** 05/15/2017 11:35 pm »

Was that the Highest S1 MECO Velocity to date?
Velocity and Burn length compared to heaviest GTO Drone ship landing?

Are you referencing the heaviest successful GTO landing or the heaviest failed GTO landing?
