Back in the day, they were scrubbing like...

often.

#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
And there'd be like a three-day, five-day, seven-day, you just never knew.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
So I go home and I watched the live stream of it.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
So I didn't even get to experience my first launch.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
And anyone that's ever tried to go to a launch can probably empathize because, yeah, scrubs are very common in the spaceflight world.

#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
So that one, I didn't get to see.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
But since then, obviously, I've been able to attend very many launches.

How much do you understand the control involved in the landing?
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
I couldn't tell you a single thing about the code and the avionics behind it, but I can tell you all the hardware that makes it happen, if that helps.

If I remember, again, this is well outside of my domain, but...
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
They code in a common language.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
It's probably going to be C. Yeah, I'm pretty sure it is.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
And that was one of the things that was weird is that Elon, when he started SpaceX, was like, we're just going to code in the most common language so that we don't have to have people learn this archaic language.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
For sure.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
Yeah, well, one of the fun things to remember, too, specifically with the Falcon 9 and the Falcon 9, or Falcon Heavy boosters, I mean, it's the same thing, basically.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
They shut down all but one of the nine engines.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
And even with that one engine at its minimum throttle setting, it's still too much thrust to hover.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
So as this rocket's coming down...
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
If they start a little bit too early, if they light that engine too early, it will actually stop above the ground and will not be able to lower itself.
