  • The energy required to get out of Earth’s orbit is exactly the problem. You can run fifty missions to the asteroid belt from Earth. Or you can send one big mission to Mars, including all the advanced hardware that’s needed for them to run asteroid missions. They can then produce the rough equipment, including fuel (CO/O2 fuel can be produced on Mars quite easily, and once a source of water can be found, so can CH4/O2, and the color comes from all the iron) and then they can send fifty missions to the asteroid belt. What you’re saving is the effort it would require to get all that rough material out of Earth’s gravity.
