The lunar dust spread in space may constitute an effective protection for the Earth from sunlight that contributes to combating climate change, according to what a team of researchers saw in a study published recently by the “Plus Climate” magazine.
These US-based scientists wrote that the “large amounts of dust” between the Earth and the sun could “limit the amount of sunlight received” by the planet. The idea is to create something like a barrier that allows part of the radiation to be blocked to mitigate climate change, and the researchers simulated a number of scenarios, including the scattering of dust particles from a space platform located at one of the Lagrangian points, where the gravitational forces balance between the Earth and the sun.
It is likely that this dust will thus form a protective barrier, but it can be easily dispersed, which requires re-scattering of dust every few days. Scientists also proposed another solution that they saw as promising, which is the scattering of lunar dust directly from the surface of the moon in the direction of the sun by rockets. And they explained that they had identified “orbits that allow dust grains to provide shade for days.” They explained that the advantages of this method are that this resource is abundant on the Moon, and that it requires less energy consumption than a launch from Earth.
