Forget satellites: launch water, rocket fuel, 3D printing material!

Relativity Space is building 3D printers large enough to construct orbital-class rockets in one piece. Others will follow. If they can make printers work in vacuum at 0g, that's how we build our next-next generation of space stations. SpinLaunch wants to launch around the clock, multiple times per day. Just keep flinging materials and consumables to the construction robots building our future habs.
