NASA Confirms Evidence That Liquid Water Flows on Mars

I wonder if people realise Mars will be the second home for humanity in the future, no matter if it is within this century or the next milenium, the fact is that Mars is the only body on the solar system that we can actually live in like we do on the Earth withous any enclosed habitat or spacesuit if we terraform it properly.

That is not just an opinion, any major space agency or specialized individual can confirm it, Mars is within the Sol's habitable zone, it is cold right now just because the thin atmosphere, else it could have oceans flowing, also the daytime is 24h37m which is incredible close to the Earth, and there is the axial tilt of 25° also near the same as the Earth, it only lacks an atmosphere thats all.

Nothing is perfect, we have 3 main cons:
- Low-gravity (0.38g), still seems enough for the human body work properly (need more studies around it)
- High eccentricity (9.3% compared to 1.7% on Earth), which means larger temperature differences from summer to winter on Equator and south hemisphere.
- No magnetic field, it doesn't prevent life or expose anyone to lethal radiation doses, but certain impact diseases from radiation at some level, still nothing too alarming.

It should be noted that the low-g DO NOT prevent terraformation on Mars (or even on the Moon) as some say, not even Earth is protected from that, Earth atmosphese escape to space very slowly, lasting billion of years. The difference is that on the Moon or Mars it escape faster, but in the Mars case it certain can stay stable up to million of years before any atmosphere replenish is needed (probably hundred of million of years), that is not a concern at all.

Also as everyone know, as the Sun gets older it becomes bigger and hoter, which means while the Earth habitability decreases, Mars habitability is increasing and in the end it may be the last habitable planet on our system. Earth is supposed to become unhabitable within 1 billion year, probably in less than 500 million years.

And yes i love these space exploration stuff, i wish the world care more and invest more into it, like on a international base on the Moon, the best place to get experience for far less risks.
