Re: More space news!
More difficult because it's different. There's no highly reactive oxygen, but then you can't just ship over slightly modified versions of the fossil fuel-driven equipment we use here, either. You would have to invent a low-g, hard vacuum, remotely operated ore processing and machining operation from scratch. Over the long term it'd still be the way to go, but it will take a while before it'd be cheaper than just launching from Earth where all the manufacturing is, despite the higher g.
