I've got a technical question: Does anybody have any idea what a ring that comes off second stage nozzle right before the engine fires is? You can see it at 1:2

You can see it at 1:21:27 on the SpaceX webcast
- ericcumbee 13y agoProbably just a protective cover they put over the engine. my guess is a glorified garbage bag.

- rrmm 13y agoDidn't see the exact place in the video, but perhaps you are talking about the nozzle stiffening ring? http://www.spacex.com/news/2013/02/09/falcon-9-flight-1-pictures http://www.spacex.com/news/2013/02/09/falcon-9-flight-1-pict... has a still of it happening on a previous flight towards the end of the page.
- trothamel 13y agoAccording to http://www.spacex.com/news/2013/02/09/falcon-9-flight-1-pictures http://www.spacex.com/news/2013/02/09/falcon-9-flight-1-pict... , it's the nozzle stiffening ring. I'm guessing that it's there to help with handling the incredibly thin nozzle extension in gravity, and that once the craft is in freefall (or under exhaust pressure) it's no longer necessary.
