Can clouds of Moon dust help fight climate change on Earth?

At minimal, we would wish Moon bases, lunar mining infrastructure, large-scale storage, and a approach to launch the dust into space.

No human has even set foot on the Moon in additional than 50 years. Whereas China is seeking to set up a Moon base by 2028, adopted by the U.S. in 2034, a well-functioning mining and dust launching system is probably going many many years away.

One other benefit of solar geoengineering is supposed to be fine tuning.

Injecting aerosols into the ambiance can in concept be fine-tuned to cut back damaging uncomfortable side effects. Altering the place aerosol injections happen, as an illustration, can drastically change potential side effects and its risk profile.

An enormous space cloud gives no such precision.

A regulation and coverage vacuum

To make issues worse, the world presently has little in the best way of coherent coverage or governance for space and the Moon. Many basic questions on human exercise in space, akin to the way to handle the growing layer of bullet-speed space junk orbiting Earth, are unanswered.

Additionally unanswered is one other basic query: is Moon mining even authorized? Who “owns” space, and the assets in it?

At current, now we have a patchwork of contradictory insurance policies.

The 1967 Outer House Treaty prohibits “appropriation” of space assets (implying a ban on mining), and Article 11.3 of the 1979 Moon Treaty states that the Moon’s assets can not develop into property of a rustic, group or individual.

Nonetheless, the U.S., Russia, and China haven’t signed the Moon Treaty. In truth, the U.S. has Obama-era legislation, a Trump-era executive order, and a non-binding international agreement — the Artemis Accords — that every one emphasize industrial useful resource extraction.

With such contradictory coverage in place, lunar mining is a fundamental legal gray area. Taking pictures Moon dust off into space is one other authorized dilemma a number of steps down the road.

As above, so beneath

Such a authorized patchwork exists due to broader political firewalls.

Equally to how the Twentieth-century space race mirrored Chilly Conflict geopolitics, up to date space governance is formed by at the moment’s political rifts. Russia and China have not joined the Artemis Accords, deciding (paradoxically collectively) to go it alone. However disagreements over a non-binding settlement are simply the tip of the iceberg.

Political disagreements over Moon dust deployment might show much more harmful. Completely different nations might desire completely different extents of cooling, or whether or not Moon dust cooling must be used in any respect.
