Once space mining is unlocked, every 1 unit of rare metals used returns 100,000,000 units of rare metal, plus 100 space infrastructure
Once space infrastructure reaches 1,000,000, no rare metal investment from Earth is required any more, 100,000,000 units of rare metal are still delivered, and space infrastructure expands by N*1.05, where N is the amount of existing space infrastructure.
Eventually space infrastructure eclipses Earth infrastructure. Once Space infrastructure reaches 1,000,000,000, units of 1,000,000 space infrastructure are designated as Interstellar colony infrastructure and accelerated towards other stars.
On arrival, these 1,000,000 Interstellar space infrastructure unit colonies being mining and producing and growing themselves.
