The Halo Drive: Fuel-Free Relativistic Propulsion of Large Masses via Recycled Boomerang Photons

28 Feb 2019 Kipping David

Gravitational slingshots around a neutron star in a compact binary have been proposed as a means of accelerating large masses to potentially relativistic speeds. Such a slingshot is attractive since fuel is not expended for the acceleration, however it does entail a spacecraft diving into close proximity of the binary, which could be hazardous... (read more)
