Congress Passes SPACE Act To Support Asteroid Mining

[Strazdas]

Ok lets look at more numbers. The highest concentration of iridium ever found in an meteorite is 4.47 ppm. So to mine 1 kg of iridium you would need to extract and process 4.47 million kgs or 400,000 tons of asteroid. I strongly doubt that you could do that from 65 kg of mining equipment. Furthermore the cost of Iridium is only $4200 per kg, its simply more expensive than current methods of iridium extraction. Currently iridium is extracted from the by products of millions tons of copper ore refining each year. So Iridium does not require separate mining to produce.

we got enough iridium here on earth. you are much better off mining other metals in space.

but ok, lets try Iridium.

First, in our solar system, iridium is 5 times more abundant in comparison to earths crust. so that 4.47 turns into a minimum of 20, realistically far more if we are going for asteroids that are rich with it and not diluted by being on earth for millions of years. in general, asteroid concentration is far larger because it didnt had the weathering effects of being inside a living planet.

so to mine 1 Kg of iridium you would actually only need (1/(20/1000000))= 50.000KGs, or 50 tons.

secondly, your prices are also incorrect. Iridium is 4200 per 100g, not kg, so thats 42000 per KG.

but yes, like i said, iridium is a bad example because we dont actually lack it on earth. We do lack, top pick example you used, good quality gold. gold is very useful in electronics due to its good conductivity and longevity. there is gold in pretty much every electronic item you have. though mostly low quality industrial one because good quality one is expensive.

Lets pick another example: Helium 3. a material we are lacking. It is valued at over 1000 dollars per gram and can be used to provide clean energy and a lot of other stuff.

Its abundance on earth is around 2 parts per million, while on the moon it is 50 parts per million. In space it is believed to be 300 parts per million - 150 times more than on earth.

This means that to extract 1 g(1000 dollars) of He3 you need only 3.3KG of the stuff. Lets assume we land an asteroid equivalent to previuos example: 50 tons. that would mean that we would have 15 KG of He3, worth 15 million dollars. And thats if we assume average concentration instead of high concentration asteroid mining.

You made a false assumption. Iridium concentration on Earth's crust is 0.001 ppm. So average concentration in space is only 0.005 ppm. The start point for my calculation was a meteorite with highest concentration ever found of Iridium. I was making the best case scenario in which a large asteroid was found with with 894 times the average ppm.

Now moving a long to your He3. To process for extraction of He3 requires 1000s of high rpm gas centrifuges each weighing well over 1 ton. Furthermore these centrifuges need to sited exactly level as any imbalance will cause the centrifuge to fly apart. Then there is the gigawatts of power required to run them for months. Again it's simpler and cheaper to bombard Lithium with neutrons to create He3 or extract He3 from the primary coolant of heavy water PWR reactors.

Except that any corporation is well within it's rights to own all the supplies necessary to support said venture. The US government can't technically take that away from them.

the corporation is under the jurisdiction of the country it is set up in (lets assume US for now). therefore, US govenrment has direct jurisdiction over said company and thus can do whatever the fuck they want with it.

Well, no, not technically according to the rules. The US Government cannot do anything so long as that company is not harming anyone and it paying it's taxes. I mean, we could argue about what is possible all day long, but I'm talking about what is strictly in the realm of the rules as they stand now. My point was also that a government isn't necessary for such an endeavor. Not that the US government couldn't wrongfully and amorally use it's monopoly on violence and use of force to do whatever it wants.

And yes, a company must follow the rules of the country in which it resides. But those companies are not powerless, as a matter of fact you can easily argue that a massively rich company has more power than anyone else in a country like the US.

No profit?

Au contrare! Space is the ultimate possibility, but because it is much greater in size than any continent on this planet and much further away, the amount of money you have to sink into it in order to get the return invetment WILL be dramatically larger. What you forget is that the return is that if we were, say, to indeed start mining a planetoid (an asteroid of significant size) for resources, we do get it all. It's a dead rock in space. No environmental concerns, no possibility of infringing on another lifeform's lifestyle, no nothing. Just the drills and regular deliveries of material to planet Earth until basically the giant space rock is finished. And that's just a giant space rock. There's whole worlds of diamond out there. And while coveting that would devalue the diamond as valuable jewelry, we cannot forget the industrial use of said diamonds.

Why travel millions of miles when you make diamonds in the lab on earth? Why mine 100,000 tons of asteroid to get Iridium when you can get Iridium from slag left over from millions of tons of copper and nickel refining. Why go to the moon to get He3 when you can create it from bombarding Lithium with neutrons. There is nothing that exists in space that can't be extracted here on Earth by cheaper means. Why investment 100s of billions when cheaper methods of extraction already exist.

I have no notion of how well that works or whether that will always meet the fullness of our needs. I do know that we make some pretty awesome advances around here, but eventually we will have to go out there. Some sort of deficiency will not be able to be worked around with clever innovation and we should be prepared for that.

Synthetic diamond is 20-30% cheaper than mined diamonds in the gemstone market. Its still cheaper to mine low grade industrial diamonds currently. If demand goes up it's still going to be cheaper to make diamonds than traveling millions of miles to get them. Nasa has just spent $671 million on getting a 65 kg satellite into orbit around Mars. That's roughly 3 times is weight in gold and thats without a return trip. To mine 1kg of Iridium from an asteroid with concentration the same as the highest ever found in meteorite, would require the mining and refining of 40,000 tons rock. Currently Iridum is refined from the cost fee left over from electro smelting of copper and nickel ores. Its done using simple cheap 19th century chemistry on the same site where the ore is refined.

There is a reason why Iron ore isn't air freighted and its the same why there isn't space mining. The transport cost make both uneconomic.

snip about minerals

I don't think the first thing that corporations are gonna go after are minerals, in regards of outer space resource extraction.

At our current stage of space development, water is far more valuable.

Aside the obvious fact that water is a necessary part of life support, it can also be turned into hydrogen fuel and oxygen: the two main ingredients for outer space rocket propulsion.

One of the things that make space launches so costly is the ridiculous fuel ratio that's needed to launch something into orbit. It's somewhere around 90%. That means for every 1 kilogram that you want to send up, you need 9 kilograms of fuel. You'll also need to build a container that's large enough to house all the fuel and that's alot of extra weight, which requires even more fuel.

Once in orbit, depending on what you're planing to do, you also need fuel to maneuver around. That's more fuel, which increases the payload even more, 1 extra KG of fuel is actually 10 KG before launch.

But what if there was a gas station in orbit? One that not only carried all the fuel that you were gonna need for your mission, but also all your water and oxygen needs? That's alot of excess weight that we can drop from the payload, making space launches much more profitable. What's more, it allows for the potential of building ships that never have to land again. Imagine a space shuttle equivalent that picks up cargo/crew pods from small payload launches and takes it to the desired destination. A series of manned mission to the Moon/Mars could theoretically all be services by the same ship.

All that's required to build such a station is a smallish comet or an asteroid with confirmed ice inside it, tarp that can envelope it and a microwave generator, along with solar cells for the energy needs.

Relevent information

No no, I do understand that you have the information at your fingertips, but what I am saying is that at some point there will be a reason to do so even if we have plenty of clever techniques up our sleeves now.

NICE ONE! Seriously, good show. I'm kicking myself for not thinking of that quote.

On topic: I sure hope we don't inadvertently piss off a more technically advanced alien species and get into an intergalactic war over... I don't know... Unobtanium or something.
