If humans are still evolving and can adapt,

Maybe their next generations will be real Martians.


Is there any chance that any species on Earth can be sent to mars and its oxygen is maintained normal-then decreases a little-then little more and at last to level of mars.
Will it adapt or its next generations will adapt to that reduction if its done very slowly.

There's a double whammy involved here.

Mars is colder so more oxygen will be needed just to keep warm as a true martian.

In my opinion that film is one of the best films ever.; it offers scientific insights into the question here.

Evolution doesn’t really happen that fast.

A relevant issue is actually shown in The Expanse, as well as The Martian. Anyone spending time there will see reduced bone density and probably loss of muscle unless they are very diligent about simulating a 1g environment often enough to mitigate the effects of lower gravity, as they do on the ISS. A Martian would likely find it quite difficult/painful to go to earth and be subjected to its gravity.

Also, we don't really have any good idea regarding human developmental changes at lower gravity as well as long-term impact on health. What we know about is mostly from few individuals with few going longer than a year. There are also changes in the immune system (which likely is only partially related to gravity) and potentially other rewiring going on. But at this point much is just speculative. It is possible that the main issue is having issues going back to higher g, but there is also the risk that the our bodies are going to experience issues that are not easy to adapt to.

🤔 Mr. CharonY ,

Biomedical mitigation will doubtless be well ahead of where it is at present ; the list of medical conditions which have yielded to modern medicine in the last century is endless . So too will be the list of those conditions mitigated by near-future cures and treatments , these likely including those engendered by partial gravity .

We’ve been putting people in low-gravity environments for ~60 years. It’s not like this is a newly-uncovered issue.

Yes,i am aware of that.

The atmosphere of Mars is primarily composed of carbon dioxide, with significant amounts of nitrogen and argon, and trace amounts of other gases like oxygen and water vapor.

Modifying an organism's characteristics through gene manipulation and altering its DNA to introduce new traits or enhance existing ones can make them suitable for that rough atmosphere?

Tardigrades can be the creature suitable to live on mars.

Which is not evolution, and not straightforward to do, even if were ethical to do on humans.

“We” (in the thread title) does not refer to tardigrades

Small organisms could have trouble if they have features to overcome gravity (e.g. they leverage adhesion to surfaces allowing them to climb) that become problematic in lower gravity. There are a lot of variables to consider, and in threads like this, people often focus on only a small subset of them.

I know that,
But my point is that they have characteristics needed.

Yes,you are right.
But we dont know what happens in future.

Therefore, we should to use androids, thousands of androids. With AI, and robots operated by humans, on the place. Self-replicating (would be prefered) androids, which can make all works we do on Earth: mining, producing, construction. Android do not need the shield from radiation and they do not breath.

I can't see this working - it takes an advanced industrial economy to make advanced machinery. Robots and machines more advanced than anything in current use will be even harder to make.

What materials are needed? How many mines, refineries, factories and roads, railways, power stations, power grids to produce them? Can they build those before they break down or wear out? We don't even know if (just one example) any usable copper deposit exists on Mars. Copper refining can be amongst the least complex (in an oxygen rich atmosphere and availability of fossil fuels or bio-fuels) but it is still no simple matter. A lot of different minerals and mines and refining and manufacturing processes would be needed for a complex robot. Robots that eat dirt and shit out refined metals might make interesting stories (Benford's Galactic Center SF stories come to mind) but it takes extraordinary imagination.

One thing for wealthy AI robots on Earth with a healthy bank account to order tools, workshop machinery, materials and parts online from competitive suppliers - seems unlikely enough - but making all those themselves in a desert far, far from any specialist suppliers? Specialist suppliers only exist because economies are very large and markets, even for specialist items, are large enough to support them.

On the other hand...

The higher the technology level , the easier and cheaper to make devices are .

Consider the Model-T automobile ; making these today would be ridiculously simple , yet they could easily be made to last forever.

Mars is currently a bridge to far for much in-situ utilization , but the next era of techno-industrial advancement will likely make that practical .

As to negative medical effects imbued upon settlers by the Martian environment ; advanced biomedical facilities will be able to produce the necessary drugs and other treatments , while weight-suits combined with exoskeletons will enable the "Martians" to stress and load their musculoskeletal components while accomplishing the physical tasks necessary to keep the colonies functioning .

Honestly, that just sounds like wishful thinking. Something that is quite popular among the techbro crowd. Real issues will somehow be magically fixed by technological advances while at the same time very current and actual challenges (ranging from undervaccination of folks to rise in antibiotic resistances) are ignored. It is not to say that those feats are impossible but there are no guarantees, either.

An illusion; the complexity and capabilities of the underlying industrial economy has to grow to make that possible. Large scale economic demand makes investment in advanced mass production possible - that makes low unit prices possible. A lot of R&D and long running investment is needed to develop new technologies and a lot of that is indirect, ie having a variety of advances across multiple industries for a variety of reasons, which can be turned to new purposes.

Overall large size and continuing growth of such economies makes that more likely.

None of it happens in isolation; model T Fords didn't arise until metallurgy was making more consistent steels and alloys, as bar, sheet, tube etc of higher and consistent quality and selling it in large quantities and cheaper. Workshop machinery of better quality and capabilities and less cost were being manufactured and marketed widely. The marine and railway sectors probably drove a lot of that.

The supporting, enabling economy and infrastructure has to be there. That is not present on Mars.

Accurately predicting the future of technology is notoriously difficult. All you can truly predict is that, barring some catastrophe, we will have improved our capabilities. Advances in capabilities often reveal new obstacles that need to be overcome

Gentlemenses ,

True , it is difficult to predict exactly when we will gain specific capabilities . However , once we can make our Model-Ts (so to speak) , we can easily ship them out to distant lands without having to manufacture them there . 🤓

I was thinking that,
Mars might have some different types of microorganisms and bacteria.
It have different environment too, so we will get unique diseases too?

Possibly, but we’ve not detected any thus far.

IMO we are not really close to even sending a human to Mars, let alone sending a bunch of them to settle there. When we can't even survive in a closed environment like Biosphere here on Earth, what hope is there for doing so in a far away place with conditions so much more hostile?

🤓 Fellow Spacers ,

Pathogenic diseases take enormous lengths of time to develop from scratch . No pathway for their development has yet existed on Mars, so... scratch !

The biggest risk by far is the same one that already exists on our space-stations , that of mutated pathogens fielding profoundly greater transmissibility and lethality than they normally possess .

New Scientist

Bacteria on the space station are evolving for life in space

Genetic analysis shows that microbes growing inside the International Space Station have adaptations for radiation and low gravity, and may pose a threat to astronauts

Well, we have plenty of pathogenic bacteria in our bodies, too.

So... , wherever we go , we'll bring our own "sick" with us , and maybe back to Earth ! 🤓
