The Soviet Almaz space station system is an adaptable set of orbit-assemblable parts that forms the basis of the Soviet Space Force of 1979. For the last several years, hundreds have been constructed and launched from Star City, most as spy satellites and platforms from which to drop their crewed nuclear bombs.
The promise of private spaceflight brings with it the conditions of the socioeconomic systems from which it stems. By the mid-22nd century, there are so many private space operations that the asteroid belt and many of the minor bodies of the solar system are crawling with mining operations. Their primary function is not to send their goods back planetside — such an endeavor requires more ∆V than it’s worth in most cases — but to supply other interplanetary operations.
