Proposal calls for wilderness protection as startup space miners look to the stars
The Guardian said:Great swathes of the solar system should be preserved as official “space wilderness” to protect planets, moons and other heavenly bodies from rampant mining and other forms of industrial exploitation, scientists say.
The proposal calls for more than 85% of the solar system to be placed off-limits to human development, leaving little more than an eighth for space firms to mine for precious metals, minerals and other valuable materials.
While the limit would protect pristine worlds from the worst excesses of human activity, its primary goal is to ensure that humanity avoids a catastrophic future in which all of the resources within its reach are permanently used up.
“If we don’t think about this now, we will go ahead as we always have, and in a few hundred years we will face an extreme crisis, much worse than we have on Earth now,” said Martin Elvis, a senior astrophysicist at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts. “Once you’ve exploited the solar system, there’s nowhere left to go.”
Fledgling space mining companies have set their sights on trillions of pounds worth of iron and precious metals locked up in asteroids, along with valuable minerals and trillions of tonnes of water on the moon. In Britain, the Asteroid Mining Corporation hopes to send a satellite into orbit in the coming years to prospect for nearby asteroids.
Precious metals such as platinum and gold could be ferried back to Earth, but much of the mined material would be used in space to build habitats on the moon and make rocket fuel. The European Space Agency has plans for a moon village that foresees buildings and equipment installed on the lunar surface. Meanwhile water ice, such as that beneath the lunar poles, can be split into hydrogen and oxygen and used to make fuel for probes that launch from space instead of Earth.

But which areas to protect from mining is a nuanced decision, the scientists write in a forthcoming issue of Acta Astronautica. The Valles Marineris on Mars, the largest canyon in the solar system, might deserve protection as much as the Grand Canyon is protected on Earth. But there are other sites too, said Elvis. “Do we want cities on the near side of the moon that light up at night? Would that be inspiring or horrifying? And what about the rings of Saturn? They are beautiful, almost pure water ice. Is it OK to mine those so that in 100 years they are gone?”
