Scientists think they’ve found a way to terraform Mars — and all it takes is a thin blanket of insulation over future space gardens.
A layer of aerogel just two to three centimeters thick may be enough to protect plants from the harshest aspects of life on Mars and create viable greenhouses in the process, according to research published Monday in the journal Nature Astronomy. While there are a host of other problems to solve before anyone can settle Mars, this terraforming plan is far more feasible than other ideas that scientists have proposed.
Two of the biggest challenges facing Martian settlers are the Red Planet’s deadly temperatures and unfiltered solar radiation, which is able to pass through Mars’ weak atmosphere and reach the surface, New Scientist reports. At night, it can reach −100 degrees Celsius, which is far too cold for any Earthly crops to survive.
