You can watch these test stands 24/7 with the Cows here: nsf.live/mcgregor Rocket Merch here: shop.nasaspaceflight.com/

5000psi on top of dealing with all that heat is absolutely insane. The metallurgists at SpaceX deserve a raise.
-
One Raptor 3 is about 18 times more powerful than a B-1 Bomber jet engine at full afterburner. As a former crew chief on the B-1B, I find that absolutely insane!!
-
"Rocket science" is actually quite simple. Rocket engineering is the tricky bit.
-
I don't normally comment on these...enjoy them immensely and consider myself better educated after them. But this one. I swear I heard the crackle. Normally on testing at Mcgregor, you get the rumble. That thing wanted to take the stand with it! Awesome video, and as always, awesome commentary.
-
Speaking of progress, it's amazing how NSF videos keep getting better and better. Truly amazing content and it is highly appreciated. Thanks!
-
The Raptor engine is really looking impressive as SpaceX optimizes its design. This version 3 engine puts out more thrust than the RS-25 or BE4 engines while being less than half the size. Can't wait to see a fully optimized and operational version of the Raptor engine when development concludes:)
-
You probably meant megapascals (MPa) and not millipascals (mPa). I mean sure, you could measure chamber pressure in either one but 350 bar is 35 MPa or 35000000000 mPa. Perhaps a more useful comparison would be 5076 psi, nearly double the pressure in your typical SCUBA tank. It's also roughly equivalent to the pressure 2.2 miles underwater. So yeah, it's a lot.

7:00 what an awesome visualization!
-
The sn11 flashbacks 🥺
-
Just seeing the plume itself, it really shows a vast improvement in thrust. Absolutely incredible to be able to watch this happen in my lifetime.
-
Weird how seeing a massive rocket flame hot enough to liquify metal gave me full body chills. The work SpaceX is doing is absolutely amazing. Thanks NSF for bringing us these high quality updates!
-
mPa and MPa are very different units, be careful or you might end up with a few more zeros than you intended 😉
-
Great Update, NSF! Thanks!
-
Outstanding! Gonna pass it around to my Space Cadet friends who aren’t ‘rocket scientists’ themselves; well done, team!
-
Great explanation thanks Jack and the NSF team. Throttling up after launch will be epic.
-
I think 'WOW!' is a suitable response..!
-
Reach new performance, simplify the design, improve reliability, then economize the parts. Rinse, repeat. The path to the stars!
-
The thrust is impressive but isn’t raptor 3 also going to be the cleanest design so far too? Elon mentioned that the engine itself shouldn’t need any heat shielding since there will no longer be anything fragile exposed on the engine. As well as RUD containment built into each engine.
-
Just a thought... Have you guys considered installing a seismograph (a cheap one) at the engine test sight location? It could return some useful information. Thanks, great work as usual.
