The “crazy” plan to exploit Moon dust to create a shield to protect the Earth

Recently, three astrophysicists proposed a plan to create shields out of lunar dust and shoot these shields into space.

It may sound unbelievable, but according to research, these shields are capable of blocking 1.8% of the sun’s rays, equivalent to 6 sunny days a year. The lunar dust shield will help reduce Earth’s temperature, combating global warming.

However, to do that, we need to mine about 11 million tons of lunar dust. The study was published in the prestigious journal Public Library of Science (PLOS). The researchers suggest that dust mined from the Moon would have to stay within millions of kilometers of space from Earth’s orbit before there is any hope of creating real shields against the sun’s rays. But how exactly do we get lunar dust into space?

According to the plan, we will mine dust on the Moon and use large guns placed on the surface of the Moon to shoot this dust towards Earth. However, the risk is that we can’t control much, can’t be sure where in the universe they fly.

Uncontrolled floating dust will require us to shoot more dust into space, which is almost synonymous with the requirement that we keep doing this as long as we want to use such a dust shield. As risky as it may seem, this is not the only plan to create obstacles between the Earth and the Sun to help the Earth fight climate change.

One of the other plans is to create cosmic bubbles and place them between the Earth and the Sun. However, all these plans are very expensive because sending objects to space is not easy. And there will certainly be more initiatives and plans to respond to climate change invented in the future.
