Dust is a simpler explanation. | |
| Sep 2, 2019 at 8:34 | comment | added | BlueCoder | I would also add that on the drone video published by SpaceX it is very clear that the plume is bright yellow right from the start during takeoff. Dust can explain the color of both takeoff and landing, no need to add engine pieces. See: twitter.com/SpaceX/status/1166822634874490880 | |
| Sep 2, 2019 at 0:55 | comment | added | Camille Goudeseune | Scott Manley's video at 3:25 show that the glow starts half a vehicle length below the nozzle, then progresses to the nozzle within a second. That supports dust entrainment, and casts doubt on engine crud burning. At 7:58, the excerpt from Tim Dodd's camera shows a few yellow puffs, but no sustained glow before the vehicle is deep into the dust. So I still claim dust entrainment. | |

| Aug 27, 2019 at 23:30 | comment | added | uhoh | Interesting question! Just fyi SpaceX edits their YouTube videos after some period of time to remove segments with no activity, so it's always good to include a time from the launch clock as well. I've edited the time in your clip so that the video plays properly now that they've dramatically shortened it. | |
