This is huge: *current* liquid water on Mars.

Mention it on Facebook.  Everyone trusts Facebook.  LOL!

Ooh, ooh, say that TRUMP named it Lake Hillary!

Hope you didn't loose a wad of cash with Super-Zuckerberg last week.  Facebook is a guaranteed investment!  Just like Tesla.

I hear Elon Musk in doing OK.

Ah, not his finances ... he was so hard up, he was asking for a loan from Zuckerberg ;-)

Don't touch that water. Be forewarned. I watched Doctor Who. I know what happens next.

I like Isaac Arthur's videos, they're very informative:

I think we'll have to get over our planetary chauvinism if we really expect to colonize space in a big way. Any planet we want to live on will have to be terraformed, which is very expensive and time consuming. It's a lot cheaper to build our own habitats that can be as comfortable as we'd like them to be.

We'll have to pound ice balls into Mars and generate greenhouse gases.

We can live in the lava tubes, but I'd colonize Valles Marineris first, the deepest parts, over three miles below the surface, will get the first dense atmospheres.  Damn up a few deep spots and you have a "Hab" without a roof.

That could work for a small number of people, but I doubt many could live there. Maybe a few thousand?

You do realize that Valles Marineris is the length of the US, from New York to LA, with numerous side canyons? We start with small canyons, only a hundred miles long, and expand as the atmosphere gets thicker. We'd alway be below the mean surface level of Mars, so the air wouldn't "get away". Living in the cliff walls make instant "skyscrapers" and radiation shelters.

So where does the new atmosphere come from, comets? How hard would it be to capture enough comets to add a significant amount of nitrogen/oxygen to Mars? How long would that take? How much would it cost?

We're terraforming a PLANET. /hint

More than a bankrupt humanity can afford.

I am The Mule.  Your Foundation has cracks in it.

It would be so massively cool to find a any type of microbe.

I agree it is very unlikely, but man... if we did, life is suddenly everywhere.
