A solution to the climate crisis: mining the moon, researchers say
Proponents of a moonshot idea to deal with global heating have been handed a new, very literal, interpretation by researchers who have proposed firing plumes of moon dust from a gun into space in order to deflect the sun's rays away from Earth.The seemingly outlandish concept, outlined in a new research paper, would involve creating a solar shield in space by mining the moon of millions of tons of its dust and then ballistically eject[ing] it to a point in space about 1m miles from Earth, where the floating grains would partially block incoming sunlight.
