Finally! This was supposed to be the Lollapalooza of launches this last 4 days. 5 launches and a hop. The last possible one finally happened...and the weather window only opened up 4 minutes before the attempt. We really need to figure out how to launch in wind...

eta: whoops...forgot the Kiwis haven't missed their shot yet. For some reason I thought all of the others had pushed windows or had aborts.

T+20 minutes. Good solar array deploy.

not sure if i should ask it here..what was the spinny thing at T+4:06 mark in 1st stage camera angle?

Ice or frozen oxygen. They form on the vents and break off from time to time.

Was that a fairing half and parachute opening just to the left of the grid fin in the video at T+4:25?

That seemed like a very long landing burn. I was paranoid that something was wrong.

Incredible flight, love seeing the ground track.

Ground track complete hugs the coastline of Florida. Miami just had some amazing views.

Unfortunately we saw nothing here in Miami. We had 100% cloud cover.

No
At 4:25 the first stage has conducted it's boostback burn and is far from the ballistic trajectory of the fairing halves, which were pushed further downtrack by over a minute of the second stage burn.

T+30 minutes. New Zealand on the left will also be launching a rocket today.

It looks like they may have actually even overflown Miami directly slightly, but given the momentum from the dogleg it also likely never had an IIP over Miami either.

Good graphics of the IIP and more in this post

No. It was spinning next to the S1 grid fins which deploy after boostback burn.

I am aware of that. The fairings should be way in front of the first stage. But I've watched it several times and it sure looks to me a lot like a parafoil opening with something hanging underneath it. Amazing coincidence?
