Climate: researchers suggest using lunar dust to protect us from the sun

Finally, another solution seems more promising to them: to disperse lunar dust directly from the surface of the Moon in the direction of the sun with rockets.

“We have identified orbits that allow dust grains to provide shade for days“, according to the researchers, who highlight the advantages of this method: an abundant resource on the Moon and a lower energy expenditure than a launch from Earth.

However, they recognize that for the moment it was a question of exploring the theoretical potential of this technique, rather than considering the feasibility.

“We are not climate change or aerospace engineering experts“, underlined Ben Bromley, professor of physics and astronomy at the University of Utah, the lead author of the study.
