Classification and acquisition method of unmanned deep space raw materials
Raw materials are divided into: ordinary minerals (iron, cobalt, carbon) and special minerals (carbon dioxide, ammonia, vaseline, etc. ), gases (radon, nitrogen, sulfur), crops (cactus meat, gamma roots, etc. ) and animal materials (feces and rotten vines).
The acquisition of common minerals is the simplest, which is found on almost all planets, but the simpler method is to buy them directly, and almost all trading places can buy these minerals in large quantities. Iron/carbon can also be obtained by bombarding the planet surface with spacecraft at close range on a planet rich in minerals/plants.
Animal materials can be obtained on any planet with animals, rotten vines can be obtained by killing animals, and feces can be obtained by feeding animals with biological particles. After obtaining a certain amount, you can plant rotten rattan roots and rotten intestinal flowers and collect them like other agricultural products.
The acquisition of the other three raw materials needs to be harvested in a specific ecology. The details are provided in the table below.
