When SpaceX test fired their Raptor engine on Sunday a few people asked me about the green coloration in the exhaust, while trying to answer this question I came across an image appearing to show a rocket engine with a bright green flame rather than the light tinge seen on the Raptor.
Oh yeah.. and I’m still sick.
oh man, the super bowl shade was amazing
Lithium-Flourine, that’s what you want !
Why are rockets so damn cool?
Damn it … have to build one …
I thought they were running the rocket on Lovecraft!
It might be toxic, but I think I’m in love with the colour!
Ive said it many times… Elon Musk will get us to Warp Drive!!! I know it!!! Mark my words !!
@ScottManley, I was wondering where your accent is from?
Scott Sassley taking it to the NFLman.
0:11 enjoying the weekend
0:14 realising there’s school tomorrow
Confused. He said Richard d clark but showed a book by john d clark. Same guy? Guy talked about in the book?
They also sometimes will use a heat sink nozzle on a test engine that lacks a full cooling system as it doesn’t have to be flight weight and the can make rapid changes to the design.
quality superbowl roast
Outro music please!!
You always have the answer. Get better so you can continue bring us even more answers
thank you for space video with science
Could you do a video on your favourite (hard) sci-fi books? Mine is Seveneves by Neal Stephenson. WE LOVE YOU SCOTT!
Been a lot of rumours of a prototype aircraft flying out in the desert for some time now that also gives off a green exhaust plume due to some exotic fuel they are using?
Hey Scott, you can get a nice green burn by putting borax (common household cleaner) under a lighter/blowtorch.
I’m just glad you poked fun at that bad halftime show
257 bar Pc; impressive..
Richard D. Clark? On my one it says John.
I’ve designed a hydrogen peroxide and ethanolamine engine before and with some additives, the exhaust products are green. Both literally colored green and environmentally green.
1:25 – What was wrong with ye olde sparkplugge?
Thanks for answering that question!
Recently I got ‘Ignition!’ as a birthday gift. Got on my wish list after the plug here, a while ago. Looking forward to it but first I need to finish Michael Collins’ Carrying the fire.
My first reaction (:P) to Musk’s second tweet: “how is milli Tesla relevant in a thruster?” Use newtons, not weird made up units.
Can you explain that standing wave that happens in the exhaust stream. You called the shapes Mach diamonds. Does it improve performance at all or is it just a side effect.
Tinting a rocket engine any color for flight would be easy. It would also look amazing.
I’m more curious about why only 3 of the 4 engines of the model are firing
I grew up with the space program (graduated HS in 1964), saw the Apollo 17 launch, saw a shuttle land at Edwards, toured the Goldstone Complex, and you’re STILL teaching me new things! Keep up the good work. 😊
Ignition is a fun read.
Smh, Scott. I had a lot of respect for you then you said “terrible super bowl”… on of the best Defensive battles Ive ever seen
Gonna put the “Richard D. Clarke” down to you being under the weather…
Dekaborane was investigated pretty extensively for the Zip Fuel program too iirc
I am interested in rockets but you know the environment is so toxic
That Superbowl roasting tho
Honestly with pentaborine chemical toxicity doesn’t scare me nearly as much as the asbestos-like crystals that get sand blasted out the nozzle as a result of the chemical reaction…
I see Elon Musk purchased the Green Engine colour for Elite: Dangerous.
I am amazed you are not an actual engineer – so much enthusiasm!
Wildfire rockets. That’d be pretty epic.
Richard D Clark? Didn’t the book say John D Clark?
Actually the Green Lantern fuel was used on this test. Thanks Scott, love your commentary, never miss a post.
I’m Scott Banley, fly safe! 😂 Get well, sir!
stolen necron techonology corrupted machine spirit , adeptus mechanicus and inqusition we need you
Having read Mr. Clark’s book, and having particularly enjoyed the exotic fuels chapter, my first thought when I saw green exhaust was “chlorine trifluoride.”
GREEN FLAME!

Hey Scott, I read Ignition! and loved it! Do you know any other books like it in which I could learn more about rockets/space exploration history or anecdotes?
That thumb nail reminded me of hydrazine drag racers in the late 50’s. The exhaust would be green and the fuemes could kill or send you to the hospital
Dude, you’re my favorite rocket channel because your videos are full of knowledge. Just FYI.
I just started chapter 10 (it’s about Boranes) in Clark’s book Ignition! It is a fantastic read even if you don’t understand chemistry that well.
Here’s an excerpt from chapter 6. He’s writing about Chlorine trifluoride, ClF3, or “CTF”:
“All this sounds fairly academic and innocuous, but when it is translated into the problem of handling the stuff, the results are horrendous. It is, of course, extremely toxic, but that’s the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic
that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water —with which it reacts explosively. It can be kept in some of the ordinary structural metals — steel, copper, aluminum, etc. —because of the formation of a thin film of insoluble metal
fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminum keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.”
Duh it’s green energy! 🤣🤣🤪
Thanks, Scott, and get well!
Fred
“Toxic exaust fumes” you say?
So its perfect for any rocked engine intended to be used above enemy territory.
I was going to complain about the shortness, but you shouldn’t be making videos when sick! Haha. Thanks for making a video even with a frog in your throat.
Feel better!
That _Ignition! _ book puts me to sleep with 100% success rate.
The rocket was probably conjured up by the Green Lanterns.
the Minuteman III ICBM has 4 rocket nozzles on the first stage
Zip, Fuels I’ve not heard that in a while . Thanks for this post .
I just finished Clark’s book, per your recommendation several months ago. Fun read. Is there a follow on volume from 1970 to present?
Is Z.I.P. fuel the same stuff to light the afterburners on the SR-71?
But does it sound like “Sweet Victory” from Spongebob?
Don’t worry Elon, neither does the NFL.
I tought it was a zinc-sulphur propellant.
1:09 my dad nl
Can always recognize a fellow BART rider by the flu.
Love getting my notifications from Scott!
Thank you for the wonderful channel!
Engine Detailing: €4,50
I’m pretty sure John D. Clark isn’t Richard.
Spacex has burnt more than on superbowl halftime show and it also soundes better lmao
When I saw the original video from the test, I thought “i wish Scott Manley would do video about this green flame”.
Thank you Scott Manley.
3:40 heresy and liquid oxygen? Sounds about right.
Hey Elon! mT means milli-tesla, not metric tons.
0:53 Design requires 170 metric tons of force, engine produced 172 milliTesla instead.
I haven’t watched the video yet, but I’m guessing it was green because it was Apple flavored?
TEB, Like the SR71 used to light up the engines and afterburners
You forgot to mention that the rocket burn is also a lot more interesting than the Superbowl halftime show… Maroon 5 and the less talented half of Outkast? Yeh, pass
2:52 – And only three of the four are firing, for some reason.
That cam cant handle the thrust of the Raptor!
Would like to nominate Scott Manley for the best space themed YouTube intro.. even that’s more interesting than most the other people doing space vids. 🤘
Hey Scott I worked at the Edwards AFB,
A F Rocket propulsion Laboratory for Fifteen years we did use pentaborine flourine’s and a few others nasty Oxidizers like that wonderful
nitrogen tetroxide. I did get a bad case of pneumonia from the last one. I was the shop know it all on propellants in the shop and had saved a lot of old rocketdyne propellant guide books on stuff like chlorine trifluorine, MMH, UDMH, N2O4 and Pentaxborine. That shit makes one again of RP1! I was there when a crew practice loading a strap-on stack for a Titan dropped a segment and burned up a test stand. And the 10-11 months of repairs that lead to failure of the same basic stack that destroyed the test stand again and the last set of firings that happened 24 months later because after that stack blew that stand needed much more work.
I cannot repeat enough times how much I love these timely short videos. 🙌
What is this superb owl you speak of?
Scott get well soon 😇😇
Today’s fact: Amelia Earhart and Eleanor Roosevelt once ditched a White House dinner party to go on a joyride flight to Baltimore.
We still need a nasa rocket that has red, white, and blue exhaust that would be launched on July 4th
The captions have you saying they are using “boring fuel”. Just what did Elon find while digging out his tunnel?
Sassy Scott Manley is the best. Also, it looks like one of the engines on the SLS model failed.
Green flames are so pretty though! Why does everything beautiful has to be toxic?😭
Hey whose extremely bald and masculine avatar is that to the right side of the screen at 1:09?
Triethylborane was also used in the SR-71 Blackbird to ignite the JP-7 fuel because it had a very high flash point.
The super bowl shade is real in this video
Tell us about the toilet that exploded on iss
You should interview Elon in the near future Scott. When you are feeling better of course.
Somebody bought the green engine trails on elite dangerous.
I do like those Mach diamonds… and yes it did sound better than the halftime show
Who had the brilliant idea to add RGB to Rockets? I fckn love it
They should launch on St Patrick’s day with that green exhaust.
…. and probably sounded a lot better… muwahha cracking me up here rotflmao
Can we please cancel the super bowl and use the stadium instead for showing off rocket engines?
How can it be toxic when it’s obviously green power?
“Which means that it probably burned more fuel than that Super Bowl halftime show – and also sounded a lot better”. *Savage.*
Just covering up the fact that they use Kerbals for propellant. Absolutely disgusting and twisted.
