Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as surface of the ground, but radar measurements show that underneath the dust there are glaciers composed of frozen water. New studies have now calculated the size of the glaciers and thus the amount of water in the glaciers.

How to maintain a thick atmosphere with low gravity and no magnetic field. That’s the problem. Certainly sub-surface is an alternative to making the surface livable. And I think that’s certainly the way to go on the moon.
But maybe when we’re really ready to colonize Mars (as opposed to the silliness of going there now) we’ll have some tech we can use to mitigate the surface problems.
Build giant silicone domes on the Moon and ship them to Mars to be set down on craters.
Good idea. I like it.
Glass is an excellent building material if fabricated in a near vacuum.
Why is that?
Silicon used to fabricate in a vacuum can be formed without impurities, making it harder and stronger than steel on earth. It is also transparent ... transparent aluminum anyone?
