The concept of a space station. That uses rotational movement to create artificial gravity is not new.

"Representational image: The rotating design structure would provide constant gravity-like environment to the astronauts." (InterestingEngineering, Russia plans rotating space station with artificial gravity to protect astronaut health)

The concept of a space station with artificial gravity, where rotation creates the necessary movement, is not new. Famous German engineer Wernher von Braun innovated the idea of the wheel-shaped space station in the 1950s and 1960s. The wheel-shaped station would orbit Earth at high or medium altitude. The rotational movement forms. Artificial gravity. And for that, the station benefits from the rotational movement. 

The rotational movement causes a centripetal force that keeps things on tables. Somebody. Sometimes says. This concept will not work because the rotational movement must be so fast that it can create artificial gravity that matches Earth's gravity. The fact is that. The rotational movement must create only such a strong gravity that it can turn from roof to roof and floor to floor. 

In zero gravity conditions, there is no roof or floor. The artificial gravity, even if it's weak, can anchor things on the table. Things like magnetic rings can pull those space station parts together. This means they can resist centripetal force better than without magnets. 

There are plans. To make large-sized space stations in a stationary trajectory. Those stations would support orbital operations. Like repairments of civil and military satellites. There is also a possibility. High-orbiting satellites can shoot capsules. That pushes other satellites from their trajectory. To the atmosphere. 

This helps to clean orbitals from space junk. And those systems can also act as ASAT platforms. In some models, the space stations can have a plasma system that shoots a plasma beam. Sometimes, iron dust is introduced for that purpose. The system can shoot iron dust using a magnetic cannon. And then that dust pushes the targeted satellite. To the atmosphere. 

To the space junk or a functional satellite and pushes it off the trajectory. The same system that can push space junk. Into the atmosphere. Can push functional satellites. To the atmosphere. 

Space stations can have 3D printing systems that can create parts for satellite structures. This means that large-sized space stations are multi-use platforms. They can support the large-sized atom rocket assembly in the Earth or Lunar orbiter. The lunar orbiter is the better solution. Because in the case of accidents. The nuclear material. Drops to the Moon.
