How would mining an asteroid work?

Miners on asteroids would use techniques similar to those used on Earth. The most likely method would be to scrape desired material off the asteroid, and tunnel into veins of specific substances. Scraping, or strip mining, will pull out valuable ore that will float off the asteroid.

Is asteroid mining better for the environment?

The results indicate that asteroid water mining would have environmental benefits, as soon as the amount of water supplied via mining is larger than the mass of the spacecraft used for mining.

What is the most valuable asteroid?

Davida
The most valuable asteroid in the belt is Davida. It has a diameter of 326 kilometres and has a resource value of almost $27 quintillion.

Why do we need asteroid mining?

Since Earth’s resources are finite, the relative abundance of asteroidal ore gives asteroid mining the potential to provide nearly unlimited resources, which would essentially eliminate scarcity for those materials. The idea of exhausting resources is not new.

Would asteroid mining destroy the economy?

If the amount of mineral wealth on this asteroid were ever to be exploited, the price of precious metals would crash. Inflation would probably rocket up by thousands of millions of times. International currencies might become worthless, and the economy would grind to a halt.

How many billions is 700 quintillion?

700,000,000,000,000,000,000
As we said, the big ball of awesome is worth upwards of $700 quintillion, which, in numeric terms, is 700,000,000,000,000,000,000. To get some type of context for this number, it is enough to give our 8 billion population of Earthlings $93 billion each.

Why is asteroid mining bad?

Notable asteroid mining challenges include the high cost of spaceflight, unreliable identification of asteroids which are suitable for mining, and the challenges of extracting usable material in a space environment. As of 2021, less than 1 gram of asteroid material has been successfully returned to Earth from space.
