Almost a year ago, the space science community watched as an asteroid entered Earth's orbit and circled above our heads for almost two months before departing. Scientists usually track such asteroids because of the risk they pose for life on Earth. But although they can pose a threat to our planet, asteroids are also potentially worth many billions of dollars because of the precious metals they contain. This is why space entrepreneurs and scientists are gearing up for the next asteroid visit, with the aim of capturing future space rocks and mining them.
Most asteroids orbit the sun within rings between Mars and Jupiter known as the asteroid belts. And importantly, some of those asteroids are full of metals that could be used to make laptops and smartphones; metals such as platinum, cobalt, iron, and even gold. NASA once calculated that the metals in these asteroids could be worth $100 million for every person on Earth, and mining even just 10 of the most profitable asteroids could yield up to $1.5 trillion.
