The flip looked good right until it didn't stop in time. Looks like the engine startup sequence on the landing burn was not as clean as it needed to be Quoting: Astromut Yeah, I 'm sure they learned a ton, and the next one will be a success! it was cool. |

User ID: 77326814 United States12/09/2020 06:04 PM Report Abusive Post Report Copyright Violation | It appeared to be a successful test to me. Quoting: Major Doom They will apply the data to SN9 on the next test. It appeared 2 of the 3 raptors ignited and simply came down way too fast. Just have to initiate the sequence a bit sooner. after watching the replay a couple of times... agreed re 1 raptor not igniting on landing burn, which explains the RUD. regardless, pretty fucking cool. ss |

User ID: 19885016 United States12/09/2020 06:40 PM Report Abusive Post Report Copyright Violation | Was the green color at the end normal? I hear people saying it was from engine burning it self up a bit from low header tank pressure (a little copper in metal of engine, copper burns green). But Im no expert at all SwampCreature |

I hear people saying it was from engine burning it self up a bit from low header tank pressure (a little copper in metal of engine, copper burns green). But Im no expert at all Normally with a Merlin engine that would just be from TEA-TEB at engine startup to ignite the engine. But they were getting away from that with Raptor. These engines are supposed to rely on spark ignition instead of TEA-TEB. Is there still some TEA-TEB system as a backup if the engine isn't starting properly from the sparkers? I don't know. It could also be some part of the engine burning up because of the low header tank pressure. I believe these engines are regeneratively cooled, so if they're not getting enough fuel into the lines then the combustion will overheat the engine.  |

Or maybe the water. Quoting: Astromut The progressive shutdown of the engines was not supposed to happen? Actually it seems like that was the design all along, I didn't hear anything about that before the launch though so it took me by surprised when it happened. |

That first engine shutdown looked like a malfunction at first. The second one was a lot smoother, which made me think that the first one must have been deliberate as well. |

I hear people saying it was from engine burning it self up a bit from low header tank pressure (a little copper in metal of engine, copper burns green). But Im no expert at all Copper salts burn blue, barium burns green, at least for solid rocket fuel. I’m NAR certified high powered rocketry level 2. I do not make my own rocket fuel, my house is paid for. The burning ‘pure’ metals I’ve seen burn bright as hell. It’s hard to see color. I had a thought it might be coolant. I’ve seen fires of racing cars and sometimes there is a green color. Smoke me a kipper, I’ll be back for breakfast.
