It looked just like those Saturn V SII separation images Harder to see the ulage on the falcon 9, probably as they uses cold gas while Saturn 5 used SRB You see the thrusters on first stage for rotate to burn back but on second stage it mixes with the second stage startup. who also went before firing. 22 hours ago, MKI said: I'm sure they are already doing this at some level via simulations. Like anything else though, there are some things you can't simulate, and thus a real-life test is the only way to find the unknowns. They obviously do, during the spachdown the will get more data on how the stage behave while coming to an stop. We know they use simulations to train Tesla autopilot including scenarios who will end in a crash. We do not know it this simulation is based on an modded GTA5 until an Tesla autopilot will try to run from the police Quote Link to comment Share on other sites More sharing options...

JoeSchmuckatelli Posted January 16, 2022 Share Posted January 16, 2022 I tried a quick google to find what gives off green light when burning and have come up confused: what do we suspect lit up that wasn't supposed to? Quote Link to comment Share on other sites More sharing options...

Green flame on raptor = engine rich combustion! It happens, it's the first visible failure we see during an R2 static fire I believe Quote Link to comment Share on other sites More sharing options...

Maybe nickel. Lot of high temperature alloys use nickel. However, this page suggests copper or tungsten or molybdenum. https://en.wikipedia.org/wiki/Flame_test Moly is also used in a lot of alloys, so maybe it's that. However, I need to explain that "high temperature alloy" is supposed to mean that it remains strong at high temperatures. Not that you ignite it in a green flame. If you do that, you have kind of misunderstood the "high temperature" part of the description.

Here's the video of the accident (not by spacex, so you don't see the actual engine or flame. Just the exhaust and the colour) The sequence is normal orange -> larger green flash -> smaller blue ->even smaller red -> shutdown There was also a second ignition of the engine later however, so presumably it was not in unusable conditions after that. How it looks after the second test is unknown since it lasted only a few seconds Edited January 16, 2022 by Beccab Quote Link to comment Share on other sites More sharing options...
Piscator Posted January 16, 2022 Share Posted January 16, 2022 Copper seems most likely. Raptors apparently use quite a lot of it. It's also far easier to vaporize than tungsten. Quote Link to comment Share on other sites More sharing options...

Hope they cleared the Johns before that happened... The pickup there is a streamer's that was recording the event, and the cars of SpaceX employees have been moved - so it seems to be a case of "we don't own that car so it will have to stay there". From close up pics it doesn't appear to have sustained much damage if at all though Not sure about the port-a-potties, some were saying that they can't be moved away when they want to because of their chemicals so they probably just cleared them. Don't quote me on that though Quote Link to comment Share on other sites More sharing options...

Late to the party, but yes, it's definitely copper. Some sort of burn-through. Hence "engine-rich combustion" lol. Quote Link to comment Share on other sites More sharing options...
