My question is from thinking about space stations and how they'd ideally be spun to create artificial gravity, keeping the crew's muscle/bone health etc. Say this space station was fairly mobile, i.e. ion propulsion, maybe nuclear powered and was able to come inside a planet's atmosphere. If you're creating say 1g of artificial gravity in the space station (spoke shaped so anywhere on the spoke would experience 1g of gravitational force in the direction of the centre of the spoke), what would the gravity felt by the crew be once the station entered earths orbit for instance?.. would it be (1 + x)g where x is the gravitational force of earth at that position?
