Making Mars habitable might be possible thanks to aerogel

As far as anyone knows, Mars is currently totally devoid of life. We don't know if that was always the case, but we know that modern-day Mars is a rather hostile place to be thanks to frigid temperatures and deadly radiation. When humans eventually arrive on the Red Planet, we might be able to change that, and a new study offers a hint as to how that could happen. In a new paper published in Nature Astronomy, researchers explain how a thin layer of aerogel -- a highly porous, virtually weightles...
