We're warming up Earth just fine. Now, scientists want to do the same on Mars
According to Gizmodo, one idea is using an insulating material called silica aerogel.
It's hypothesized that an aerogel blanket could more easily melt the water on the Martian ice caps.
Such a material might therefore be useful to raise the ground temperature in the region around the Martian poles.
Tiles of the material could be assembled into a greenhouse-like structure.
