Unlimited raw materials with all the metals and minerals we would ever need with no environmental damage? We know HOW to do it, but it isn’t happening, because getting the needed equipment and fuel to orbit is way too expensive.
Are we alone? There’s no more fundamental question in all of science than to ask, “is there other life out there?” We should go explore all the planets and moons that might harbor life. We could build habitats in space for humans to live and explore the solar system safe from radiation and the debilitating effects of weightlessness, but getting the needed material into orbit is too expensive.
Reusable rockets have made a dramatic improvement in the economics of space, but the price of getting to low earth orbit is still $1,000.00 per pound. EML can deliver at $3.00 per pound.
That’s why Electromagnetic Launch.
