Mark Rober

Because on Mars, there's no oxygen.

And stuff doesn't break down.

So a million years from now, those rovers are going to be sitting there.

Your shit's going to still be there.

And it's like, where the hell did this come from?

Um, you know, one thing that's interesting about space is like, there's no air resistance.

So once you get up there and you, you, you start, you just, you just thrust at the beginning, essentially you get up to about 25, 25,000 miles per hour.

That's like five times faster than the bullet.

And then you just coast for the rest of the period, right?

You just accelerate.

And then you go to where Mars will be in nine months.

And they have, and you get like three or four times to do little course corrections, but those motors, we call them mouse fart motors.

Because when you're 90 million miles away and you're just getting that initial thrust at the beginning, you know, fractions of a degree mean you miss the planet by, you know, tens of thousands, hundreds of thousands, a million miles.

So it's just this tiniest little poof just to the side.

And because of that, okay, now you're going to hit Mars when it comes around.

So it's really interesting, the math orbital mechanics.

It seems really complicated, but because there is no friction, it's like, you know, for a computer, it's pretty easy to do.

And then we eventually learned tricks of, like, orbital slingshots.

So you actually go around planets and you pick up speeds, kind of like, you kind of slingshot around, right?

So it's a really fascinating...
