Off-Earth mining:
minerals and organics from asteroids;
ices and organics from comets;
industrial materials from Jovian and Saturnian moons, Mercury and Mars;
nothing from Venus.
Notes
Chemical fractionation necessary for large concentrations of most industrial materials requires moon- or planet-sized bodies.
Mercurian mining is entirely robotic.
Venus would be too costly even for robots.
Both Lunarians and Terrans can reproduce on Mars which was a Lunarian province until the Federation took them over. (Physics and politics always interact.)

Kaor, Paul!
I like very much the idea of mining minerals, ices, chemicals, metals, etc., from off Earth sources! And we should have started decades ago.
Ordinary humans (Terrans) can reproduce on Mars because the gravity is high enough not to disrupt the ordinary woman's pregnancy cycle.
And I regard with deep suspicion and distrust the Federation taking over Luna and Mars. With amply good reason!
