I guess this is the actual beginning of asteroid mining, it's so exciting.

No it's not the beginning of asteroid mining. What in the world gave you that impression? There have been several other sample return missions in the past, this isn't the first one.

    Instead of wondering you can look it up on the internet. https://en.m.wikipedia.org/wiki/Sample-return_mission https://en.m.wikipedia.org/wiki/Sample-return_mission

  Apologies, I thought past missions were sent to comets not asteroids but you are correct, the original Hayabusa mission tried to return a sample from an asteroid but incinerated on the reentry. https://en.wikipedia.org/wiki/Hayabusa https://en.wikipedia.org/wiki/Hayabusa

    Not incinerated, why would you say that. From your link: "..tiny grains of asteroidal material, which were returned to Earth"

It is definitely cool to mine asteroids. Judging by https://en.wikipedia.org/wiki/Asteroid_mining#Potential_targets https://en.wikipedia.org/wiki/Asteroid_mining#Potential_targ..., it is also a bit weird to setup such an sophisticated enterprise to mine for elements that are readily available on Earth. Heck, Earth is a whole planet made of iron and covered in water... Asteroid Est. Value (US$) Est.
