Transcripts

Аhhh,

casually watching a video on YouTube

on a computer more powerful than anything humanity could build a few decades ago.

Тhis progress and all the wonderful machines you take for granted

are built on a few rare and precious materials

with names like Terbium, Nneodymium or Tantalum.

Getting these rare materials from the ground into your devices is ugly

The mining industry is responsible for air and water pollution

and the destruction of entire landscapes.

Dangerous chemicals like cyanide, sulphuric acid or chlorine are used to extract the resources,

harming biodiversity, workers and locals.

And rare resources are also political tools, when countries restrict access to them to get their way.

But what if we could replace the mining industry on earth,

with a clean process that can't harm anyone?

Well, we can; all we need to do is look up.

(catchy introductory music by Kurzgesagt)

Asteroids are millions of trillions of tons of rocks, metals, and ice.

Leftovers from the cloud that became the planet 4.5 billion years ago.

They can be as small as a meter or proto-planets the size of entire countries.

Most of them are concentrated in the asteroid belt and the Kuiper belt

while hundreds of thousands more do their own thing between the planets.

As space travel is becoming more feasible

scientists and economists have been begun looking at the resources found in these asteroids.

Even relatively small metallic asteroids

may contain trillions worth of industrial and precious metals like platinum.

And bigger asteroids like 16 Psyche could contain enough iron nickel to

cover the world's metal needs for millions of years.

At current market prices the rare raw materials alone would be worth quadrillions of dollars.

Well, not really. But technically.

For example, there are more than 20 million tons of gold in the ocean's water

worth roughly 750 trillion U.S. dollars.

But filtering out the gold would be so expensive that you'd lose money selling it.

Right now asteroid mining has exactly this problem.

It's too expensive to replace mining on Earth.

Billions of dollars worth of valuable resources in space are worthless

if it costs trillions to get them.

What makes it so hard?

The principals behind mining an asteroid are simple.

The basic idea is to choose an asteroid

move it to a place where it's easy to process,

and then take it apart to turn into useful products.

Unfortunately all of this collides with fundamental problems humans have yet to solve

Going to space is expensive.

It costs thousands of dollars in rocket fuel for each kilogram, just to reach a low earth orbit.

Going further out into deep space costs thousands more.

We need cheaper space travel to make asteroid mining profitable.

One solution is to switch from classical rockets to electric spaceships.

We already use electrical rocket engines for many of the space probes on science missions.

In principal, we only need to build bigger ones.

While electrical engines are not powerful enough to fly to space

they require only a tiny amount of fuel to go very far once they're in space.

This means we don't need to spend a lot of money on fuel

only to transport fuel into space.

This doesn't solve the whole cost problem-

but it makes it easier to start our first mission.

Now that we have an electric asteroid-mining spaceship,

we need to find the right asteroid and get it there.

We've already successfully visited asteroids with space probes

and even collected samples.

Still, to make it easier and cheaper

our first targets will probably be near-Earth asteroids.

Asteroids that orbit, well, near Earth.

After a few months of travel

our spaceship finally arrives at an asteroid.

Weirdly formed, littered with small impact craters,

it hasn't changed much for billions of years.

The first thing that needs to be done is to secure the asteroid and stop it from spinning.

There are multiple ways to do this,

like vaporizing material with a laser

or stopping the rotation with thrusters.

Once we have a stable asteroid, we need to wait.

Orbital mechanics are complicated,

but if you push something in the right direction at exactly the right moment,

you can move very big things with very little force.

So, we wait for exactly the right moment.

Our ship fires its thrusters and nudges the asteroid into a trajectory that takes it near our Moon.

The Moon is useful because we can borrow

its gravitational pull to put the asteroid in a stable orbit around Earth,

which saves even more fuel.

Again, the trip takes months.

But all the time since our ship was launched has not been wasted.

The first space mining and processing equipment has been installed in orbit,

and is now carefully moving towards the asteroid.

The processor works very differently than on Earth.

Giant mirrors focus sunlight and heat up asteroid rock

to boil out the gases.

Grinders break up the dried rocks into gravel and dust,

and centrifuges separate dense from light elements.

Even if we only extract 0.01% of the asteroid's mass in precious metals,

this is still several times more than you'd get from the same amount of ore

on the ground.

But what now? How do we get our precious metals safely back to ground?

There are a few ways, like loading it into reusable rockets

that return to Earth from space.

Or if our processor contains 3-D printers,

we can print a faster and cheaper delivery system.

Heat shielded capsules filled with gas bubbles.

These can just be dropped into the oceans where ships tow them away.

This could be the starting point of humanity's first real steps

towards colonizing the solar system.

As our infrastructure and experience grows,

our missions get more and more sophisticated.

Parts and fuel produced on asteroids

don't have to be launched from Earth at all.

The first mining operation makes the second one easier, and so on.

While the space industry grows

and precious materials become cheaper,

eventually we could stop mining on Earth.

Even the idea of toxic mining down here

might become something weird and anachronistic,

like having an open fire in your living room.

Landscapes ravaged by pollution will heal,

while the technological wonders we're used to

get cheaper and less toxic to make.

None of this is science fiction.

We don't need fancy materials or new physics

to make asteroid mining happen.

We could start building this future today.

All we need is an initial ... push!
