I’m so intrigued by the prospect of mining asteroids! The amounts of metals and other resources, including rarer things like platinum family metals is incredible. There are some serious challenges that would need to be overcome, but the first country or company which pulls it off would open the doors to a future where we don’t need to rip up earth to obtain all the rare stuff we need for high tech industry. And with huge amounts of asteroids being in the belts in our solar system, a practically inexhaustible supply too.
It is exciting but what’s the market? It’s hard to see this being at all a reasonable cost having to bring it back to Earth, especially unrefined, and it’s hard to imagine it not being worse than current mining, given the flight back to Earth, especially if refining is still on Earth
On the other hand I’m more excited over mining regolith and water. Such simple things, but will be a huge difference in cost to maintain any off-world presence. Shelter, radiation control, rocket fuel, drinking and bathing, growing food : water and dirt are pretty basic, but just think of the sheer tonnage of supply missions launching from Earth it could replace
I think the real value is amount of rare metals that could be harvested, scientists have found an asteroid that is comprised mostly of metals. Scientists think it may be the exposed core of a proto planet:
So that kind of haul could potentially be worth it, but smelting, refinement and processing would probably be more cost effective in space. Who knows what the future will bring, mining the asteroid belt may only make sense once we have a much strong presence in space, I.E., colonies on Mars, the Moon, etc etc.
This is a lot of exciting words to say “instead of digging up the effectively limitless amount of rock under our feet we can go into space to do it in the least efficient and most expensive way”
It’s very cool, but I would rather we spend our time and resources on more pressing things, given we have the rocks right here.
I would agree if mining the rocks on earth didn’t cause ecological collapses and kill off animals and displace indigenous and exploit underprivileged ethnic classes in post colonial hellholes
I’ll take the issue down the road over the one already in my doorstep any time of the week.
Atmospheric pollution is at least something that seems fixable with extraterrestrial resources. Ruined biospheres due to mining on earth seems less avoidable/fixable unless we go back to pre-industrial living standards.
How would it be fixable? The more stuff entering and exiting the atmosphere, the more particles. The particles aren’t from manufacturing on earth from what I read.
Particles we can bind with chemical reactions (like ad-blu for diesel engines), would be expensive and we would need to be careful to select chemical reactions that actually solve the problem but fundamentally it’s a fixable problem.
Right, so by adding more chemicals, causing more unknown issues, we can fix an unknown issue. Which we would need to strip earth for even more to get to be able to use.
How. Ruined biosphere from mining affects many discrete places that can be cleaned up, in theory. Messing up the atmosphere affects all biospheres, is much more vast, and we have to breathe in the meantime
Look at current mining - true crimes against the environment in specific places but do not directly impact most humans. Could you say that about messing up the atmosphere?
the asteroid belt is like a protective barrier. if earth’s orbit was on a flat surface the belt would be on it too. this imaginary plane is where earth is most likely to collide with extraterrestrial objects. so if it was possible to reduce the asteroid belt to half its current mass, earth would technically be more vulnerable to collisions along our orbital path. it’s not the biggest threat but i felt the need to explain that.
Rocks ≠ ore. There are numerous materials (e.g. lithium) for the total known deposits on Earth won’t cover more than a few decades’ worth of projected demand, and even then, the mining process is an environmental disaster. Asteroid mining is a long-term project that will require huge advances in multiple fields, but it addresses a real need.
known deposits. There’s functionally endless amounts of all elements we need on earth. And there is zero need to go mine asteroids at a truely astronomical cost of efficiency.
I said mostly the same thing as you in (my own words) elsewhere inside this post. Most people don’t want to see this reality.
So, maybe this is a business opportunity : to attract investment and then face investors with hard facts. Of course we write the contract so that, after this, we just keep their stupid money.
Edit : Oops ! I just read your other comment :
you’ll also see (…) investment scams
And so I realize you were thinking along these lines already. (although my statement was much more cynical)
If it’s truly the “least efficient and most expensive way” of mining then you have no reason to be the slightest bit worried, it won’t get done in that case. Obviously.
What, you think one can just snap their fingers and be done with a project like that? Its something thats never been done before. No need to be so disingenuous.
I can imagine a sort of a conveyor belt made of miniature cargo vessel with one robotized mining station at one end, cutting away an asteroid piece by piece, and a cargo dock at the Earth side.
With enough cargo vessels deployed, let’s say one would arrive at each end everyother day, the moment the conveyor belt was full, the mining operation would be swift.
Assuming a global deal between nations could be struck to have a refinery or at least a cargo dock placed on the moon, to organize large cargos to come to Earth at programmed intervals, it could prove to be a very interesting endeavour.
Raw matterials price could drop, given the sheer available volume.

Metal asteroid Psyche has a ridiculously high ‘value.’ But what does that even mean?

I’m sure mining in space will have its own problems but at least it can’t kill our biosphere
There’s been studies that have found metal particles in the atmosphere, so anything entering and exiting are seemingly shedding particles.
So it’s likely to cause issues down the road unfortunately.

Makes total sense!

Isn’t one of the current hot topics among environmentalists carbon capture, which is “cleaning up” the atmosphere as a whole?

This is true, but you’ll also see a lot of investment scams by internet famous people, like funding a space company on the lies of Mars colonies
900 tons to orbit just this year isnt a scam.
Of those 900 tons, how many will be used to get humans to Mars?
What, you think one can just snap their fingers and be done with a project like that? Its something thats never been done before. No need to be so disingenuous.
SpaceX is a private company, it’s not taking investment from internet people.
Furthermore, its Mars goals are IMO the least revolutionary part of what the Starship program is working toward.
Investment scams from internet people. And I said scam like promising Mars colonization. I did not use the term revolutionary. Scam.

At least it sounds like a diferent sci-fi plot
You could do that on earth
Which part?
All of it.
