How SpaceX manufactures a new raptor engine every 24 hours shock the entire industry...

The Raptor engine is the muscle of the SpaceX Starship program. Thirty-three of these Raptor 2 engines power the Super Heavy booster that serves as the vehicle's first stage, and six more are used by the Starship upper stage. For a successful lunar mission, these engines will need to re-light successfully on the surface of the Moon to carry astronauts back to orbit inside Starship. If the engines fail, the astronauts will probably die.
Luckily, so far, SpaceX has done "very well" in working toward the development of a vehicle to land humans on the surface of the Moon, especially the new Raptor rocket engine.
"SpaceX has moved very quickly on development," Mark Kirasich, NASA's deputy associate administrator who oversees the development of Artemis missions to the Moon, said about Raptor. "We've seen them manufacture what was called Raptor 1.0. They have since upgraded to Raptor 2.0 that first of all increases performance and thrust and secondly reduces the amount of parts, reducing the amount of time to manufacture and test. They build these things very fast. Their goal was seven engines a week, and they hit that about a quarter ago. So they are now building seven engines a week."
But that's still not enough Elon Musk has even set his expectation that SpaceX has to make a capacity of 2000 raptors per year.

So many people are going to be blindsided when they realize how much progress has been made. Most people don't have it on their radar what is to come.

One of my new favorite terms, "Uncontrolled disassembly". Great reporting.

[ARWest-bpyb]

I for one am not shocked, or even surprised, but I am thrilled!😄😉 Great reporting!👍👍

You describe how SpaceX outpaces NASA, but not why. The why is: government programs operate on a completely different set of incentives than private sector programs. We see this everywhere in government. Government is not good at doing things.

All I can think about is how all of the numbers are not just the best one person can do, but the best our species is capable of doing in our entire existence. Congratulations Humanity!

3:55 quick correction: Oxygen molecules are NOT lighter than methane molecules. You reported the mono-atomic mass of oxygen, the molecular weight is double this.

Pretty incredible how positivity and willingness to succeed at all costs is so infectious that it can bring this many people together with the common goal

3:40 "in pursuit of the greatest possible efficiency Raptor's turbopump will run oxygen rich. . ." As I understand it the Raptor engine is a full flow stage combustion cycle. A full flow stage combustion engine uses both oxidizer-rich and fuel-rich preburners. The cycle allows full flow of both propellants through the turbines. That is to say, one preburner all of the fuel and some oxygen runs through (fuel rich). The other preburner all the oxygen and some fuel goes through the burner (Oxygen rich).

$100 million for 1 RS25 ? were a raptor 2 costs $250, 000 if not less ! Nasa needs to start putting there funding to better uses than blowing it all on old technology and spare parts !

[Digmen]

So now I know how to make my own space ship!
American industry is amazing

[Michael-ijkg]

So much dense information.
So rare for commentary on materials/ metals science, thanks!

[chadgdry]

2000 rockets a year / 365 days in a year = 5.5 rocket engines a day.

[andrewnorgrove]

Would love to see version 2 on a bench being pulled down after a mission with re-lights, Good video you got my Subs

[lilblackduc]

Outstanding presentation with Facts/Figures/History and 'Lively Editorial Comment'! Thank you...🇺🇸 😎👍☕

[howardkeller]

Is doesn’t take that much. Just has to be a very brilliant man! Doesn’t happen every day. Doesn’t happen often. But it does happen. And when it does, it is absolutely amazing!

[WillNGo]

Good video. Terrific information. Elon Musk has repeatedly said "We realized that the true problem, the true difficulty, and where _the greatest potential is_ – is building _the machine that makes the machine."_ Anyone who understands what he meant, and what Tesla and Space X are doing and then invested based on this has made a lot of money and will make a lot more.

For me the huge difference between NASA, and also other space agencies like ESA, is the vision for the future. Spacex have a plan for the future and knowns that only an industrial mains can be achieve this goal. To reduce the costs a market is needed and space created the market like Starlink to have payload for Falcon 9, manufacture in serial the rocket, reduce the cost by launch and then to be competitive to gain clients.

Please explain 3:50.

Oxygen atom = 15.999u
Oxygen Molecule = 31.998u

Hydrogen atom = 1.007u
Carbon atom = 12.011u
Methane molecule = 16.039u

Now in an elevated temperature I would imagine these molecules breaking down into ions and therefore oxgen is still the heaviest there with carbon coming second at 12.011u.
And why would you want a less dense fluid going through a turbo pump if you had the choice? less dense means you either need higher gas velocity (temp) to extract more energy from the dynamic pressure, or more fluid flow overall.

The real reason is it's a Full-Flow Combustion Cycle engine. One pump does fuel-rich, the other does oxidiser-rich and when both streams of the pumps are merged in the main combustion cycle, they are both nice and hot gas fluids that burn very cleanly.
Now to get that to work IRL is not easy without it blowing up and SpaceX have done a wonderful job at making it look easy.

I've now looked at comments below and I'm not the only one

[Redvines]

"Uncontrolled disassembly" I like that term :D

[facbl]

They"re mounting more than five rockets engines by day ! This guy can't be from this planet !
