Is living on Mars actually possible?

Messiah, there are two possibilities.
1. Colonisation. It will eventually be possible to have a colony on Mars, but it will still depend on Earth. It is unlikely to be self sufficient. Eventually those living there would acclimatise to the low gravity, and probably be unable to return to Earth, except maybe for short vacations.
2. Terraforming. This will never happen. The atmosphere would leak away faster than it could be supplied.

Will, we ever be able to able functionally live on Mars? It's a simple question with so many complex answers to match.

That was the question. Does anyone disagree with - limited colonisation possible - terraforming, forget it?

No.

It's not gonna be possible for another 20+ years. We don't have that much energy and the technology currently, even earthings' energy demand is increasing every year.

If you fancy elon musk kinda ideas then please don't, elon musk is more of a comedian than an actual thinker, since he's not gonna board the manned spaceship to mars, he doesn't worry sending anyone to mars to be called tony stark of the real world.

It doesn't work like that, it's been impossible for us to settle people on Antarctica, for similar reasons most of Greenland is uninhabited and so are various places on earth that resemble harsh conditions of other planets.

Mars is way too harsh than any place on earth, even way harsher than the Sahara desert.

I would say that terraforming will be no small challenge.

A study was done to simulate Martian soil/sunlight conditions to see what might work. Tomatoes seemed to work pretty well.

Recently it was discovered that cosmic rays have sterilized the surface more than scientists thought. Digging deeper is likely the new requirement to find any organic evidence. Perhaps a meter or so deep, there will be some nutrients to augment what we would need to take to Mars. It's still an open question, IMO.

Sorry, Helio, I just have this image of a couple of men with buckets and spades digging over the surface of Mars to a depth of a metre or so . . . . . . of course, they would need spacesuits. ;)

Just the men? I've a pic wherein men can be seen driving teslas on Mars.

asks OP in #1.

What does he mean by functionally? Is that functioning, as on Earth? A lot depends on the meaning of this question. Does OP mean without spacesuits?

An atmospere on Mars could be preserved by putting up a large magnet between it and the Sun to divert the oncoming solar wind and prevent it from stripping the atmosphere. Unfortunately even if all the water ice and dry ice on Mars were evaporated it would raise the atmosperic pressure to only 7% of Earth's from the current 1%. To that we would have to add twice that amount of oxygen.

The highest altitude a human can survive long term is 18,000 feet. There, the partial pressure of oxygen is but 10% of sea level atmospheric pressure. If an atmosphere on Mars had 21% of Earth's atmosperic pressure and was half oxygen, its O2 partial pressure would be about 10% of sea level pressure on Earth, right at the limit for humans.

Bill, are you suggesting that terraforming might be a practicable possibility, now or in the next thousand years (if ever)? That includes the practicability of every step in the process being viable. Example

No, I am not suggesting terraforming would be practical. Yes, the magnet idea would work, but there is no practical way to get that much oxygen. Perhaps one could go to the Oort cloud, get a bunch of comets, crash them into Mars, electrolyze out the oxygen, send the hydrogen into space. Again, not very practical.
