Who owns an asteroid?

Celestial bodies like Bennu could help us tell Earth’s origin story. Or they could be strip-mined for resources

Discussions around space travel are saturated in colonialist language and narratives, from “space colonies” on Mars to multiple proposals for mining asteroids. These concepts are often treated as inevitable, with conversations about when and how, rather than if we should do any of this in the first place. In The Nib, artist extraordinaire Maki Naro and I look at how colonialist attitudes have colored our dialog on asteroids and Mars, with a focus on the ethical and — dare we say — the spiritual component of conservation on other worlds.

Don’t pull up stakes for the asteroid-mining gold rush

Is Space Becoming a Gold Mine?

A new law grants private companies ownership over the materials they extract from asteroids or the Moon. But don’t call it a gold rush just yet

For The Daily Beast:

Asteroids are remnants of the Solar System’s youth. When the planets were forming more than 4.5 billion years ago, gas and dust molecules clung together to form larger objects, which in turn collided and stuck together to make yet bigger things. At the end of the process, we were left with the big planets, moons, and a huge number of smaller bodies which contain the raw chemicals we see on Earth.

Some asteroids could contain significant amounts of rare metals such as platinum, rare-earth elements, and other materials. Even water is a valuable resource in space, since it is useful as fuel (broken into hydrogen and oxygen components) and necessary for astronauts, but very heavy and therefore expensive to carry into space.

Now, President Barack Obama signed a bill into law granting private companies ownership over materials they extract from asteroids or the Moon. The bill also extends the period of time private corporations can develop spacecraft without direct government oversight, to help speed the process of getting more rockets into space.

But don’t pull up stakes for the asteroid-mining gold rush just yet. [Read the rest at The Daily Beast…]
