Just a side note, I'm not sure if this goes here, or in a science exchange...
Asteroids are expensive, and can easily be worth billions of dollars. They contain many types of precious metals, like gold, and platinum.
In the future, asteroid mining will be a huge business. With new advancements in technology, and cheaper launches, we can ship asteroid material to Earth, with a huge ROI.
But how will bringing back all these metals impact the economy?
