    Screenshot aus dem Livestream von Tim Dodd (Everyday Astronaut), der deutlich den glühenden Triebwerksabschnitt zeigt, der wahrscheinlich von der Erwärmung beim Wiedereintritt herrührt.

      I figured there would be some heat going on when it was still moving at thousands of km per hour less that 10km above the ground.

      While the engine bells are cooled by the propellant before being used, I’d think a lot of this heat came radiatively from the actual exhaust. Probably both sources contributed, be nice to know the percentages. Since the bells aren’t glowing and no longer being cooled I think the radiant earlier heating dominates, but maybe it’s a difference in materials.

      You mean the stream he was restreaming from SpaceX? Yes, SpaceX had a very nice quality stream.

      Im a little surprised there’s enough heat in the engine bay to make the steel glow. I figured the blunt end would have created a bow shock big enough to protect it. Then again, I’m not a rocket surgeon…

      I cannot wait for all of the 4k footage and hi-res photos to come out!

      It’s the singles greatest engineering marvel I’ve witnessed in my lifetime!

      This doesn’t look like glowing steel or engines to me, it looks like a fire being constrained to the engine bay because of the dynamic pressure. All 12 of those center engines would have had cryogenic propellant flowing through them to pre-chill them for ignition, they would not be glowing, and since there doesn’t appear to be anything different about the color around the center 12, the source of the light must be from combustion.

      EDIT: I’m prob wrong based on further information, which is even more interesting tbh!

      My guess was propellant trapped in the engine cavity that ignighted, it didn’t grow and fade like reentry heating

      Re-entry heat? Are you sure it’s not just some LED strip lights that they got off Temu for mood lighting? :p
