How can the ISS be boosted without inducing a spin given its asymmetry? Can the attitude thrusters of a Progress alone counter its main engine? [duplicate]
The ISS has been pushed in the past by Zvezda's two small thrusters (nowadays inactive it seems) and more often by a Progress docked at the back of Zvezda. However the nozzle of the Progress can't ...

Garbage powered reboosting module for low Earth orbiting space stations
Instead of dumping massive garbage packs once in a while, using a robotic arm, could some sort of garbage canon eject the same mass in small pieces, at higher velocity, so that it contributes to ...
