Gargamel Posted December 6, 2020 Share Posted December 6, 2020 Just now, tater said: Vibration? I don't think so, it's diminished as it's increased altitude. It looks like a rhythmic pulsing of some off gas. So the air pressure early on collapses the shroud, giving the gas pulses more effect. Later on the shroud is inflated, and you can't notice them as much. Quote Link to comment Share on other sites More sharing options...

I wonder if it isn't Merlin still gimballing under the passive control system. It's no longer useful, but nobody bothered with turning it off, because it irrelevant anyway.

Deddly Posted December 7, 2020 Share Posted December 7, 2020 I can't find the reference now, but Elon addressed the second stage "pulsing" on Twitter a while back. If I recall correctly, they aren't completely sure what it is Quote Link to comment Share on other sites More sharing options...

tater Posted December 7, 2020 Share Posted December 7, 2020 Timing has to be wrong on the webcast link, road closures are not until 8am local, and that puts it at 6am local. Still... HYPE. Also: Quote Link to comment Share on other sites More sharing options...
