Quantum Apostrophe: maniacbastard : What do you expect to find in there to make it worthwile to "mine" an asteroid? With what equipment? How?


What I would find, materials and minerals that formed in low gravity, in conditions that cannot be achieved on a planetary surface that may be novel. Platinum group metals as well. I would expect to find illimite and hydrates that I can use to extract liquid oxygen raw titanium and iron. Since the asteroid in question is carbonaceous, I would be able to extract carbon that with the iron that I already have, I have the ability to make stainless steel. Since I have titanium, if I bring along some vandium and other alloying ingredients, I can make Titanium. Also since I am in zero g I'd bet I I can use a single nucleation site and grow monster single crystal versions of every metal I mentioned.

How would I do it? It is called ISRU equipment and you pay me money and I magically use formulas and magic boxes called 'computers' to 'design engineer' things that do whatever process you want. I've worked on planetary drilling systems and ISRU before. it would be a technology development effort, but it requires no breakthroughs in materials or power or anything else. And the low gravity would be a nice bonus.
Given the fact that the 7 meter asteroid in question weighs 500 tons roughly, that is a lot of material to turn into something. And a great testbed for a wide variety of ISRU methods.

Because with rising ocean levels, what we really need is something to make the tides higher.
