Transcript:

I mean, do you think about the terraforming aspect?

Like, actually...

Are you still focused right now on

the spaceships part that's

so critical to getting to Mars?

Yeah. We absolutely if you can't get there, nothing else matters.

Yeah.

So...and like I said,

we can't get there with at some

extraordinarily high cost.

I mean, the current cost of, let's say one ton to

the surface of Mars is on the order of $1 billion.

So because they just need the rocket

and the launch and everything

you need like heat shield, you need,

you know, guidance system,

you need deep space communications,

you need some kind of landing system.

So like rough approximation would be a billion dollars

per ton to the surface of Mars right now.

This is obviously

way too expensive to create

a self-sustaining civilization.

So we need to improve that by

at least a factor of a thousand.
