MIT 'microthrusters' are the size of a penny, could reposition tiny satellites

Bus-sized satellites require massive engines for even the slightest movements, but as far smaller structures become a possibility, a tiny driving mechanism can offer usable thrust. To serve this next-gen tech, MIT saw a need to develop "microthrusters," which are each the size of a penny and can be mounted to tiny cubed satellites. With thruster components measuring a few microns each, the magnetic levitation system is able to accommodate 500 microscopic tips that emit ion beams in a very small package, serving to push two-pound structures through space.
