[@dragnothlecoona]

it is likely that deep underground there would be earth like pressures and temperatures multiple miles deep where there could also be liquid water. Syntrichia Caninervis moss if genetically modified to both be able to conduct photosynthesis, and chemosynthesis, then this moss could be used to seed its deep caverns as well as some parts of its surface, specifically areas with higher pressures and warmer temperatures. As a result of chemosynthesis, the break down of rocks done underground would release gases gradually increasing pressures. Many chemosynthesis using bacteria would also be necessary to seed into its caves. Mars has deeper caverns then earth, miles deeper, and those caverns would be where we would have to build our habitats.

[@dragnothlecoona]

to find liquid water on mars, it would likely be about 5-7 miles deep, with around 1-3 atmospheres of pressure at those depths and likely earth like temperatures ranging from around 50-160 degrees dependent upon the depth. Though this is theoretical. As mars has larger and deeper caverns compared to earth, it is likely there could be a lot more water then we think burred deep within the planet

[@ProfDuncCameron]

Totally agree! I’m Professor of Microbiology at the University of Manchester with a passing interest in astrobiology and if life did emerge and it’s still there then deep surface lithophiles would be my bet. So exciting

[@THX..1138]

Yes if life ever got started on Mars it's very hard to believe it's not still there....Personally I lean toward Abiogenesis being a process that happens deep underground then later migrates to the the surface. If Mars's surface becoming or even always having been uninhabitable wouldn't matter for life being on Mars now.

[@stevengill1736]

Indeed! Cheers...

[@BBBrasil]

Molecular Biologist here, astrobiology is fascinating. Several researches suggest that 1) the majority of Earth's water is in the subterranean, not on oceans, and 2) Earth's biggest biomass is also in the same subterranean for. So, yeah, if life emerged on Mars in the past, all my bets are in the deep. Next, find an emergent pocket, else it will take a long time to drill them out.

[@mushroomsteve]

I have read that the Martian regolith is full of hydrogen peroxide and perchlorates, making life nearly impossible. Maybe was there in the past if the soil composition was different.

[@Vaille32]

If there is microbial life on Mars, it would be very interesting to see how genetically similar it is to that here on Earth. The same would apply to any microbes found on Venus or in its atmosphere.

Mars have ice. Beneath the ice is my best guess. It might be water underneath because of the pressure, safe from radiation

[@kurtjohnson5412]

He did comment on that saying that as the water evaporates more and more, the little water left would have high concentrations of salt. That would be unsuitable for life. That’s why his idea is to find life where it first could have formed and not the last place it could have been.

I will live vicariously through videos on this channel because I will never leave Earth due to health.

[@BG101UK]

I'd say that Mars still has a lot of its original water quota. This is because as the atmosphere thinned out, most of it would have frozen and subsequently covered over with particles of regolith. There is seemingly a LOT of ice just under the surface, even in near-equatorial regions!

[@JohanHultin]

1,5% of the soil is made up of water ices, roughly atleast. I’d wager there is variance, especially around the equator due to it recieving more sublight and near the poles for the opposite reason. Issue is, ice so far as we know isn’t very useful in that solid state. Then again, it’s not something we know a great deal about outside of earth either.

[@rais1953]

​@@JohanHultin Where there are deposits of ice near the surface there is probably moisture deeper down where the ground is warmer.

[@yaldabaoth2]

Extremely unlikely. Even ice evaporates, it's called sublimation. Especially under the conditions on Mars for that period of time.

[@BG101UK]

@@BG101UK It's not "none" but you first claimed "a lot of its original water". How much is a lot? Mars had oceans and they are gone, blown away into space over billions of years. There's surely some water chemically bonded to minerals like you would find almost anywhere. That doesn't mean that melting tons of rocks for a glass of water is a feasible way of quenching thirst.

To me as a layman, life appeared first when the sun's protodisk appeared, before planets existed. All the gases, light, circulation was there, which formed into the planets and their atmospheres. In this essence true life evolved and went on to the planets. So I would wager, that life is everywhere in the solar system, except not so visible and palpable like on Earth. The question is where can we exclude probability of life? Life may exist in so many places: Venus atmosphere, Mars subsurface, Europa subsurface water, Jupiter atmosphere, Saturn atmosphere, Pluto subsurface, and so on....

"Mars has methane which may indicate life. However, this is not definitive proof, as there are also non-organic ways to make methane”. This means that organic methane confirms the presence of life. However, abiogenic methane is produced from organic compounds that aren't related to organisms. And this process could be happening on Mars. So the correct statement would be, "Methane can also be produced from non-biogenic sources."

As far as we know all life on earth requires water, This opens the door to the possibility that extraterrestrial life, even on a water-rich planet, could rely on entirely different biochemistries.

[@daveozip4326]

💯agree - just one addition to your list of requirements for early life: it is likely that a proton gradient is required for very early life. This is basically because the mechanisms we find in more developed life require core processes that involve proton gradients created by the living systems. Such an advanced process would not have been available to early life but external proton gradients exist which are likely starting points for early life. (Black smokers are not the most likely but white smokers have more friendly environments - cooler temps plus an alkaline based proton gradient)

[@NovaCoronaSolarisBlast]

my own thoughts, as someone who has only a casual interest in space: I'm an alien-optomist, I hope we're close to discovering life on other celestial bodies. However, Methane only immerging at night could be an easily explained non-biological phenominone; since it appears at night, could we deduce that this may be due to the cyclical temperature fluctuations? at night the martian "air" is cooler, and thus more dense as it sinks to the surface, meaning methane that rises high into the atmosphere and disperses during the day could become more dense and easily detectable. it could be that there used to be an organic source, but the current methane is a finite supply left over after billions of years, with the bulk of it trapped in the ice slowly sublimating to replenish what's lost by solar winds. regardless of the source of the methane, the search for answers will only prove to further our understanding of The Red Planet, life or not.

Everyone can form their own opinion: Tanais, Debris, Cydonia, Galaxy Chaos, Deuteronlius Mensae, Mirthis Fossae etc. etc. Today Mars is of course a kind of geological museum and life as we know it is impossible, at least on the surface, but as correctly mentioned in the video, it used to be completely different.

Their findings were inconclusive. They have not found life. They also haven't ruled out the existence of life. More research was needed. More research was done. More research is being done. So far we are pretty confident that Mars has had liquid water on the surface not too long ago, from what we found. Chances that there was life are good, but it's never aliens until it's aliens. We want more than a hint, more than a pretty good chance. We want proof. And that is not easy when you don't know what you are looking for.
