Many alloy materials cannot be fused together, and there is no such problem in space warfare in a weightless state. The United States has made a variety of alloys in space that cannot be achieved on Earth, and the new alloys made in space have the strength, fatigue resistance, electrical conductivity and thermal conductivity.
The performances are much stronger than those processed on the ground. Therefore, at this level, the importance of space warfare is self-evident. New proteins and materials can also be synthesized in the space station.
Help develop new drugs, and people can also grow plants in the space station. Because studying the growth laws of plants in space can not only provide a basis for human plant growth studies on the ground.
It can also provide an intense scientific basis for future human migration to outer space. In addition to the study of material plants, humans can also study the mental and physical indicators of astronauts in a state of weightlessness for a long time, so as to help humans provide scientific basis for more interstellar exploration and immigration.
