Would it not be ironically hilarious if the Mars spaceship ends up looking EXACTLY like the 'absurd' spaceships of 1950's space movies? :)

The sweating part is really really smart. Makes me believe that the best engineering is to copy nature.

Elon stares at Starship for a moment.
"Tell you what, throw a little hot rod red in there".

[danievdw]

You missed the real important bit. " Most steel alloys get brittle at cryogenic temperatures. That’s not the case for stainless steel with high chrome-nickel content. It gets stronger in cold conditions, but it also maintains ductility. That means stainless steel has high fracture toughness, which could prevent small structural imperfections from developing into cracks." With the cryo fuel loaded, that thin sheet of steel is stronger than carbon fiber, on top of all the other stuff you mentioned.

Starship - the actual thing that goes to Mars

"The Falcon 9 certified for human payload is a bit of a nightmare"

Me: NOT ANYMORE!!

I love how Elon is pushing new ideas, and failure together. Because success without failure is just luck lol.

Origin of "WD-40" - I honestly never knew that before!

Another amazing video again! Been a long time viewer and can say this channel is one of the reasons i'm studying engineering now

Real Engineering: Sometimes you just need to make mistakes to learn, which is why you should sign up to Brilliant.
People who sign up to Brilliant: lol won't do that again

The first liquid cooled rocket better have RGB

The ship looks like nothing else... unless you grew up watching '50s sci-fi.

My Soviet university "diploma work" back in 1987 was to test this type of cooling for rocket re-entry, porous pressed metal powder was used, however there were problems with incostintent gas flow in different parts of provided samples. Hopefully perforated solid metal will work better than baked together particles, I really hope such protection is possible (although not 100% sure), only tests will show.

Flex tape. Problem solved.

Rocket made entirely out of Flex tape.

Correction or note: It was only the fairing that toppled over. The bottom half with all the tanks, plumbing, etc stayed upright.

Other scientists: “Let’s colonize Mars”

Elon Musk: “Yeah, let’s colonize Mars, but first:

I'm British, so know you're talking in Celsius, but when you're talking about numbers in Degrees, you should always specify whether Fahrenheit, Celsius or Kelvin. The first rule of Engineering is "Name your units".
