The US Geological Survey Is Getting Serious About Space Resources and Mining

Great! Maybe they can put together a prospectus and attract some private investors. Good luck, guys!

I know it wouldn’t be a lot at first, but over time, the extra tonnage that didn’t develop on the planet will add up.

Hell no!! Those doped up parasites living off of working people can’t be beat. That is why only people that pay income taxes should VOTE!!

cost / benefit

But now it's also investigating what benefits may or may not exist in tapping extraterrestrial water, minerals and metals.

This is just a ruse. They really want to start regulating outer space. The bureaucrats hate freedom.

[Vince Ferrer]

This is kind of fitting. We don't think about it much now, but in between the Louisiana purchase and the 1890s there were decades where not much was really known about what was inside the continent. It was just too difficult for most people to get into the west, let alone get back to the settled east coast and let people know what was there.

In this period there were photographic expeditions by the USGS, mapping the interior, especially for railroad routes, and for natural resources. The first photographs taken of the Rocky Mountains were taken by the USGS.

We need good ‘Tractor Beam’ technology in order to bring all of that Space stuff here without risking the lives our Astronauts. .

My dad talked about mining gold from asteroids thirty years ago. He was a terrible father but he was also a genius. He said the problem with mining said gold was radiation. Of note he was also an engineer and worked at San Onofre nuclear plant.

The “Space stuff” is more valuable in space than it is here.

[Cvengr]

Yes, but how will you redistribute the mass so keep an even keel?

[marktwain]

I wrote a paper on the potential of mining the apollo and amor asteroids 35 years ago.

[enduserindy]

What’s your thought on radiation levels in gold from space? My dad said in the eighties recycled gold from electronics had the potential to be radioactive. He said gold on asteroids would be exposed to high levels and that gold could retain it for a very long time.

Found that. Gold would only stay radioactive for about a month.

[mindburglar]

That’s why Goldfinger’s plan was stupid.

[enduserindy]

Well I think this would be a good investment in light of that.

I know it wouldn’t be a lot at first, but over time, the extra tonnage that didn’t develop on the planet will add up.

I once saw a scientific calculation of the amount of dust that falls onto planet earth from outer space each day. The tonnage was staggering.

The amount of minerals we bring back from space will never come close to that.

There’s dust that doesn’t burn upon hitting our atmosphere? Is that diamond dust or something?

Dust motes from space don't fall to earth with near enough velocity to burn up in our atmosphere. They're almost weightless, individually.
