Mars has a lot more water than we thought

Mars used to have oceans in the past, but we just found more water on the red planet underground. More than what should be possible.

What does this mean for life on Mars? And will this help colonize Mars?\

also watch the sequel, the moon ALSO has a lot more water than we thought:

There might not be little green men, but:
There *might* be little blue liquids.

Im native to martian underground oceans, i confirm theres life! Please dont call us green people, its offend us. we are fesh. Thank for understanding😊

[Flesh_Wizard]

That just confirms it. Mars is the solar system's largest sponge

Scientists have found living bacteria with extremely slow metabolism living under kilometres of rock on Earth. It's not out of the question that Mars may have a version of this.

Hey I really loved your ~30 minute long Moon video. Maybe consider making videos that hit the 15 minute mark! I really love your channel and it will definitely become one of my favourites!

Reminds me of the (recent?) research showing that Earth, too, has a lot more water in the mantle than were initially thought, so it may turn out that instead of 100% of our oceans coming from comets, they're actually the leftovers of the original water that hasn't sunk into the mantle. If I remember correctly it's because the minerals potentially composing the upper mantle actually have a decent amount of room in their structure, allowing water molecules to squeeze inside, whereas the minerals we were under the impression before that upper mantle would be composed of were too dense to hold water. Maybe on Mars because of the lower overall pressure (due to lower gravity) that layer is much thicker so can hold an enormous amount of water. It tells me that maybe we should check Venus for this too - it might not be there, as it might have had its runaway greenhouse before much of the water managed to sink into the mantle, but it certainly might be worth checking. Mercury on the other hand, has such a strange structure I'm not even sure there's room for a decent water-laden layer. But we have found more volatiles there than expected, so I also wouldn't be particularly surprised.

I have a bit of a theory that instead of Mars losing it’s water because of its’s weak magnetic field and loss of atmosphere, it could’ve instead desiccated itself and most of the water simply absorbed through the porous soil and into large aquifers. That or perhaps it could’ve been mostly if not entirely covered in an ocean. Mars could’ve been an ocean world with its largest volcanoes like Olympus Mons being islands.

Fun Fact, Earth is hiding anywhere from 4-80 times the volume of its surface water underground.
Why "scientists" are constantly surprised that the 1st and 3rd most common elements in the Universe seem to be everywhere is beyond me 😂

I personally would put current day native Martian life at 50%+. Simply because earth life formed over 4.2 billion years ago (which is the approximate age of LUCA). This means life formed extremely quickly after the earth became habitable, and mars had more than enough time to form life in the same way. Recently, microbial life has also been found in clay deposits within 2 billion year old strata. It is yet to be confirmed that it isn’t contaminated but it looks like it isn’t from what I’ve understood. That means microbial life is likely very easily formed (keep in mind the sample size of 1 though) and that it can survive for 2 billion years in clay deposits. That is some decent steps toward native current day Martian microbial life.

I really prefer the realistic approach your channel takes, when it comes to this subject. A lot of other space centered channels are just wildly optimistic which leads to unrealistic expectations. You and Prof Kipping's channels are my favs <3

ky they updated the j1407b wikipedia article!!!

[ahsoka_polo]

Don't forget the soil itself is toxic

[RealKloggier]

is this misinformation or *missed information* ?

[alejandropoczynokh]

Thanks for the regular uploads! I hope we get to see, at least, a human colony on Luna in our lifetime.

[WombuNan]

Wait wait wait wait wait there’s life on the moon????

[thepeacefulbuddah]

While I'm not against colonizing Mars, we should definitely colonize the Moon first.
We've hade the technology to start building Moon bases for about 20 years now (We *should* have started building them back then, but I digress.)
I feel like jumping straight to Mars or Venus right now would just be a d3ath sentence for all those astronauts.

how much yall wanna bet mars lost its magnetic field because a super villain (im picturing Dr. Doofenshmirtz) used the anti-magnetic field-o-tron-5000 because his parents never allowed him to have magnets as a kid?

[houselemuellan]

I personally don't care about the profitability of colonizing distant worlds, but simply the coolness of doing so. We do so many other things for no reason just because we like doing it, so why can't it extend to something much bigger? Especially with how much of a symbol Mars is already.

Earth has microbes living near its upper mantle in the crust, I'm betting on microbes being in that wet sand.
