What's the stuff that came off the stage 2 engine after ignition?

I'm not sure if this is what you're talking about, but there is a ring of stuff at the base of the nozzle (not sure of the purpose) that falls off that I've noticed before.

Also, you're above 3000 rep!

Could be some soft stuff to protect the fragile bell from launch vibrations.

I saw that!

Also, do you think that when Crew Dragon is operational they'll show the crew portraits in the bottom right?

Wait, are you saying SpaceX just launched something when I also just woke up ? Will they keep the technical webcast ? The usual one is too often too noisy.

The ring is there to hold the engine bell's shape. The bell extension doesn't actually have any structural reinforcement-it's just a flimsy sheet of metal. When the engine is firing, the bell is held in shape by the pressure of the expanding exhaust gas, and when the rocket is coasting in orbit there aren't any external forces to warp the bell. On the pad and during launch, however, the bell undergoes a lot of external forces. Hence the ring, to stiffen the bottom edge and hold the nozzle shape together.

I thought stuff got unloaded once it got out of 2.5 km physics range. Any idea what mod they're using?

It just doesn't get physics outside that range. The booster was on rails until it crashed.

Yeah, I think so. That must've been a panic moment for them.

I remember watching that one live. You could hear the launch director do a double take when it happened. :D

OK, admit it y'all... am I the only one that's tried to spin the live-feed map-view around in different directions??? :sticktongue:

I think we've all been guilty of it at some point :blush:

Sattelite deployment!

Webcast is over. Until next time, fly safe :D
