    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’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.

          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.

      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.

        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

          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.

      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.

      At least it sounds like a diferent sci-fi plot
