Mars water: Liquid water reservoirs found under Martian crust

Scientists have discovered a reservoir of liquid water on Mars - deep in the rocky outer crust of the planet.

The findings come from a new analysis of data from Nasa’s Mars Insight Lander, which touched down on the planet back in 2018.

The lander carried a seismometer, which recorded four years' of vibrations - Mars quakes - from deep inside the Red Planet.

Analysing those quakes - and exactly how the planet moves - revealed "seismic signals" of liquid water.

Yeah, but do they have hookers with three breasts? Otherwise, I'm not going.

Colonizing Mars exposed the colonists to mutagenic radiation, causing people born on Mars to have birth defects (and psychic abilities). They weren't native Martians, so the three booby lady won't exist until we send people there.

Fun fact, the Earth has a magnetosphere that protects us from radiation, and Mars does not. So it is very likely that Martian colonists would experience higher rates of cancer, birth defects, and sterility even with physical shielding.

But also, even if a human were to grow a third booby, it would probably be above or below one of the normal boobies, along a vertical line called the "milk line." A third medial booby is, medically speaking, unlikely.

If anyone's curious, this is called "polythelia" or "supernumerary nipple" (SFW - seriously). Per the wiki, it's WAY more common than you'd probably expect, but they tend to go underreported bc people think they're just a mole.

Runs in my family, from my father's side.

Genetics are weird af.

Why a third boob when you could have a full Kuato?

Better yet, do they make me wish I had three hands?

You're doing fine with two.

"blah blah blah it's paper mache, I don't care!"

To me personally, settling mars has nothing to do with colonialism, or capitalism, or hookers and blackjack. It's about the fact that humanity is like a steam engine, and somebody threw too much coal into that thing. Now it's cooking hot, and one way to keep it from exploding is to "release steam" (in a metaphorical sense). That means, settling off to some other planet.

Is it really world news if it didn't happen on this world?

You're right. This belongs in Solar System News.

It happened on a world. 🤷🏻‍♂️

Mars is a world, it was never specified which world this community is about.

It is this world, just not this planet

That's generally what "world" means

I was in the impression that it's a much wider category

It's possible to use it to refer to a non-planet region (bigger or smaller) in a more general sense, but I wouldn't say that's the most common usage.

I guess it's like german "Realität"/"Wirklichkeit" (both meaning reality).

I understand "Realität" (reality) to mean something "real", like something touchable. Language, and literature are not "real" to me. They're "wirklich", but not "real".

The analysis revealed reservoirs of water at depths of about six to 12 miles (10 to 20km) in the Martian crust.

The deepest man-made hole on earth is 8 miles deep.

Would a deeper hole be easier to create on Mars due to the lower planetary mass? I would assume so.

Yeah, but the drill bit would need to be 140 million miles long just to reach Mars.

Nah just a 10 mile long pole, strong enough to break through planetary geological plates in a straight on blow, thrown really really really fast from earth.

If you don't care how long it takes to get there and can effectively use the ITN you don't even need to leave going that fast.

Side thought, all I can think of now is developing the technology to accelerate the rotation of some of these ITN "slingshot" planets to speeds where they become giant versions of those hotwheels motorized launcher tracks.

IIRC the problem was the ambient temp that deep being too hot causing mechanical failures. It's hard to dispose of waste heat when you have to pump it miles away.

You could probably drill much deeper into Mars before encountering that issue, though, since its molten rock is significantly deeper than Earth’s.

You know who this calls for?
