United Arab Emirates Wants To Build A City On Mars

We can't live on Mars, the low gravity will eventually have the human bodies breaking down. We can't live anywhere we can't produce gravity. The only way we live on Mars is to create ground habitats that spin, like you would have to in space.
edit: gravity on Mars is 38% of earth, humans will die from long term exposure to that low gravity.

Would humans die or just adapt ?
It looks likely that any long term resident would be unable to return to Earth, but 38% gravity is a significant percentage of Earth normal - it shouldn't be as difficult as microgravity in orbit.
People would start dying on Mars within a decade or so. Even with exer-cycles muscles and bones deteriorate, red blood cell counts fall, and humans can't adapt in one lifetime. The only way it's even humanly possible is to have an orbiting space station around Mars with usual spinning circular micro-gravity habitat and you would shuttle people to Mars in shifts. They still spend the majority of their time on the station though. But you can't just move there, you'll die without proper gravity.
It would be a costly thing, but I can see spinning ground stations at some point--if necessary.
I had a dream the other night. Someone actually came up with anti-gravity (never happen, I know) and someone put a refinery atop the NASA crawler and had it floated to Titan.

OMG.......... Imagine how that would look. That's one huge machine but with a refinery on top. It would be amazing.
To get anti gravity we have to work out the problem of gravity.. Where's Murphy when you need her?
No they won't. Even reduced gravity is still gravity, and there's an equilibrium point to which the bones and muscles cease to atrophy to be consistent with the day-to-day stresses of that gravity level. The people living in that gravity will get WEAKER than they were when they arrived, but they won't continue to weaken until they die. That wouldn't even happen in microgravity, where the constant atrophy of bones becomes immaterial just by virtue of their bones not actually needing to bear any real loads.
Put that another way: 38% of gravity is perfectly survivable pretty much forever, provided you STAY in 38% of gravity. Sudden exposure to full Earth gravity would be extremely stressful on the body, about as stressful as a person raised in Earth gravity would be during an ordinary space launch. It would hardly be lethal, but it would certainly be debilitating.
So how does it work with Trek? Planets with different gravity...
Technobabble......
It doesn't. Every planet in Star Trek has the EXACT same atmosphere and gravity as Earth, except for some tiny inconsequential difference (kinda like how all the aliens are basically just humans with shit glued to their foreheads and/or ears).
The needs of the drama outweigh the needs of realism.
There is no scientific evidence about the health costs, risks, or benefits of long-term lower-than-normal gravity. There are some fine-sounding hypotheses, but none have been tested. This is reasonable, given the difficulty in getting any test animal in a lower-than-normal but not-microgravity environment for any appreciable time. But anyone pretending that it is not something we need at least provisional answers to before committing people to long-term stays on Mars is not serious about committing people to long-term stays on Mars.
Or they're a little TOO serious about it, to the point that they would consider "Here's what killed MOST of the colonists and here's what killed the rest of them" a really valuable data set.
I've been saying for years now: if we're going to really commit ourselves to expanding humanity into the solar system, we're going to have to get used to the idea that ALOT of people are going to die out there. Most of these, if we're lucky, will be volunteers who go to their fate willingly and die for the cause. If we're not lucky, they'll be conscripts who didn't get a choice or otherwise rational people who were lied to about the risks.
Don't use puny humans that require food, oxygen, water, warmth, radiation protection, health care, sleep and waste recycling to do a machine's job. If there are any resources out there worth extracting or any structures that need building, use robots. If humans need more room than is available on Earth, have the robots build space colonies that rotate to simulate gravity. It's pointless to drag the meat bags out of one gravity well only to drop them down another, onto what are effectively toxic, inhospitable environments.
Colonization is its own reward. People move to a new place with the intention of exploiting the resources in that place for financial gain. The whole point of colonization is to go where the resources ARE, so that you are a seller/exporter rather than consumer/importer of those resources. This allows a person to create, rather than merely acquire, wealth.
The expansion into space will be undertaken by people looking to strike it rich in the new un-tried opportunities of the solar system. Many of the people who seek those opportunities won't live to exploit them, and many more will come back empty handed. A few will succeed, and eventually thrive; others will follow in their footsteps looking for their own fortune, or looking to cash in on that success by coming to work for the new successful industries.
And everyone, everywhere, will be utterly convinced that it will never happen right up until the day it finally does.
And the new frontier will be like the wild west...... yay.....
Now who will take the part of Bravestar or Zachary Foxx?

Chances are that the resources will only be of value to the Martian residents. Transport costs to/from Earth will ensure that.
Well, no... it'll be more like the colonization of the New World, except there will be about twenty different East India Companies all competing for claims to asteroids, comets, and little slices of individual moons. There are probably going to be some pretty nasty corporate wars and issues with piracy, theft, kidnapping and protection rackets, all made more complicated by the fact that commerce will expand into the solar system ALOT faster than law.
Elon Musk and Jeff Bezos, or probably one of their grandkids.Now who will take the part of Bravestar or Zachary Foxx?
