“One of the classic tropes of science fiction is terraforming Mars: warming up our cold neighbor so it could support human civilization. The idea might not be so far-fetched, research published today in Science Advances suggests.

Injecting tiny particles into Mars’s atmosphere could warm the planet by more than 10°C in a matter of months, researchers find—enough to sustain liquid water. Although the scheme would require about 2 million tons of particles per year, they could be manufactured from readily available ingredients found in martian dust.”
