Spice mine
Spice is fuel, a research material and the most valuable resource. The colder your planet, the more your spice mine produces.

No spice, no flights: every flight burns fuel, including every save flight. On top of that come research, many buildings and units, and the Thermosolar plant, which burns spice continuously. At the merchant spice is the most expensive resource.
Production depends on the planet's temperature: the colder the planet, the more spice. The temperature comes from the planet's position on the map – the farther it is from the sun, the colder it gets. You can find it in the planet info. Set your planet's temperature in the level table to see the matching values. More under Planets.
The Spice mine has the highest energy demand per level of all mines, so plan for more energy than with the other mines. Warm planets, on the other hand, suit Solar cells better, since they deliver more energy there. That makes for a sensible division of labour between your colonies.
At level 6 the Spice mine unlocks the Thermosolar plant and the Particle shield. Like the other mines, it benefits from Mining technology and from production bonuses.
Background
Spice is harvested directly in its elemental form and the production of this ressource is dependent on the development of the mining facility and the planets orbit around the sun. Only in colder regions of the solar system, this otherwise rather volatile commodity can be effectively stabilised in a solid form. Essential to the imperial trading it is needed as fuel for military operations and civilian transports. Based on its complexity in combination with other materials, this material bears unforeseen possibilities, so that huge quantities of this material go into research. This material also has a dense packed high energy structure, therefore it is used in weapons and power plants.
