The goal of self-replication in space systems is to exploit large amounts of matter with a low launch mass. For example, an autotrophic self-replicating machine could cover a moon or planet with solar cells, and beam the power to the Earth using microwaves. Once in place, the same machinery that built itself could also produce raw materials or manufactured objects, including transportation systems to ship the products. Another model of self-replicating machine would copy itself through the galaxy and universe, sending information back.

太空系统中自复制的目标是利用低发射质量的大量物质。例如，一个自养自复制机械可以用太阳能电池覆盖月球或行星，并通过微波将能量传送到地球。一旦就位，自己建造的同样的机器也可以生产原材料或制成品，包括运输产品的运输系统。另一个自复制机械模型会在银河系和宇宙中复制自己，把信息传回来。
In general, since these systems are autotrophic, they are the most difficult and complex known replicators. They are also thought to be the most hazardous, because they do not require any inputs from human beings in order to reproduce.

一般来说，由于这些系统是自养的，他们是已知最困难和复杂的复制因子。它们也被认为是最危险的复制因子，因为它们不需要人类的任何投入来繁殖。
