@7:30 [right camera] I haven't seen this occurring in a long time, and even now it's not as prominent as once upon a time, but can anyone explain the ""heartbeat"" of the mylar (?) bag around the Stage 2 engine?
It's very faint nowadays, and I've been wanting to ask this for many many months, but all the footage didn't present it. I can only assume there was some small upgrade to the engine system, which had lessened whatever is occurring...
EDIT: Case in point! The following footage with the Starlink launch, I can't see it beating... 😑 lol
My only thought on what that might be is some sort of pressure release valve. 🤷♂️
If memory serves me correctly, in addition to being more pronounced, the pulsing may have also been slightly slower (longer delay)? It would only be a difference by of maybe 200ms, putting the more noticeable rate at around a 1sec interval, compared to now's ~800ms.
Thanks!
