To sustain long-term life in space with no bone deterioration advanced gravity was needed to perfectly replicate Earth's one. Very soon Antigrav coils were invented that for a relatively cheap price produced the adequate gravity environment for humans.
Crystals are mined in the Crysalys asteroid field. The ore found there has superior conductivity and beam focus propertires that make ideal for beam-based weapon production.
Gold is still a much coveted precious metal. Industrial uses include fabrication of corrosion-free eletrical connectors that are vital in harsh, humid and corrosive atmospheres.
Solidified water can be found in specific parts of Gemini. Its many uses include melting down for hydration and production of fuel. It is in high demand in places where it is not naturally available.
The largest consumer of tellurium is the metal industry. Its brittle, mildly toxic, silver-white metaloid characteristics are used in the production of alloys, solar panels and superconductors.
The primary use of titanium in Gemini is the production of TitaNova plates as it is one of the most durable elements with highest strength-to-density ratio.
