NASA is studying an asteroid called Psyche 16. This giant "space rock" could be filled quintillions of dollars in gold.
To put it another way there is $1,000,000,000,000,000,000's in that shiny bullion everyone likes to invest in and horde. Plus all those electronics, computers parts, use as a medical use in some surgeries, and whatever....
Psyche 16. NASA
NASA will be sending a probe to the asteroid in 2022. This probe will journey hundreds of millions of miles from Earth and finish its trip to Psyche 16 in 2026.
How and who and when and if this asteroid is actually mined for its potential gold is something we will find out in the next few years or so. If NASA's attachment allows for the public's investment via tax dollars allows the public to earn something from these space mining expeditions, then there is more potential for the public to support more research and development.
