It was amazing to watch, the engines glowing on reentry was insane!
The engines glowing made me reeeeeal nervous
I was waiting for the overheat indicators to pop up
It was crazy to see the engines glowing but the nozzles cool, such an unexpected scene!
Was that atmospheric heating from the re-entry?
Purely from compression, not from friction. Honestly, I’m curious how they guard against backflow in the nozzles. A tesla valve would be cool, but I also have no idea how those perform in ultra-high-pressure/flow scenarios
Exactly. The everyday astronaut footage shows it particularly vividly.
