It's, uh, I mean, it's beyond hypothesis and it's theoretically possible that we could, that we could, uh, extract propellant on Mars.

How would we do that?

So there's actually quite a bit of water on Mars.

Um, and most of it's like a salient, it's like in the,

It's in the dirt.

It's not just freestanding water.

Some of it's not even ice water.

It's literally mud.

But if you can separate it out, which is going to be somewhat energy intensive, but you can separate out the water.

You can then boil off water into, you can make it using electrolysis.

You can get liquid oxygen.

You can get oxygen.

Then you condense it down and freeze it into, or lower its boiling point into liquid oxygen.

But then you can take that hydrogen, mix it with the, there's a lot of carbon dioxide in the atmosphere there.

you can then create methane actually using a process called the Sabatier process.

And you can actually get methane on Mars as well.

And they actually think it's easier to do methane almost than it is to do hydrogen on its own because it's just more energy dense.

Well, technically not more energy dense, but the specific energy is lower than hydrogen.

But in the scheme of like getting to Mars and refueling methane seems like the right choice.

That's bonkers, bro.
