Mars used to have enough water to have an ocean but because it doesn’t have an atmosphere space stole it through evaporation and winds. Mars still has a lot of water locked up in ice deep underground. So technically you could figure out a way to harness that and keep it in a closed loop system and you’ve got yourself an extraterrestrial data center.
The issue is more likely the end of Mars’s magnetic field which it likely lost when the much smaller planet cooled enough that its metal core stopped moving as a fluid, and ceased generating a global magnetic field.
With that gone there’s little left to protect the atmosphere from solar wind and it got stripped away. The atmosphere Mars has today is very thin and comprise of heavier gasses like CO2 which may spend part of the year precipitated into solid form on the surface.
low atmospheric pressure makes more of the water ocean turn to vapor, which the solar wind strips off the planet. eventually, most of the surface water is gone except for that which is frozen solid at the poles or subsurface
Sure. But it would cost more money than has ever been created across the entirety of human civilization on earth. Meanwhile we have a perfectly good planet in earth that we are already living on.

Don’t they need water?
