How the discovered ice on mars could make teraforming/colonization more feasible

[Red_dragon]

With the new information about the high ice deposits underground Near the equator, A base could harvest the ice. This means a near-equator colonization is feasible. A full colonization is much more feasible. How could we use this water for teraforming?

It would take one heck of an engineering project to pump it up from those depths. It's not like oil, which is already liquid... the land would also slump. Probably best thing to do is strip the tops and input energy to melt it. If there were even a little CO2 frozen in with the mix, or in clathrate form, it would make quite a significant addition to the atmosphere.

There is a lot of frozen water on Mars.  for Terraforming I don't think the location is very important. More heat would help more and new volatiles, such as nitrogen from cold asteroids or Titan would help a lot more.

The 3m thick water ocean equivalent would, if electrolysed, release enough O2 to create about 0.1 bar of pressure, and a lot of hydrogen on the side. Hydrogen is a great greenhouse gas, if you can retain it somehow at Mars. There's alse the minor issue of setting the planet on fire with an H2/O2 atmosphere if you choose to hang on to both.

Don't need water for that. Mars has lots of hematite, which can be electrolytically reduced to iron, with oxygen as a byproduct. Iron is useful for structural purposes, of course. Better than just wasting all that hydrogen and water. https://www.tandfonline.com/doi/abs/10.1179/174328108X293444
