A note on relativistic rocketry
arXiv:0910.1965 · doi:10.1016/j.actaastro.2010.06.050
Abstract
In the context of special relativity, we discuss the specific impulse of a rocket whose exhaust jet consists of massive and/or massless particles. This work generalizes previous results and corrects some errors of a recently published paper by U. Walter. (The errors stem from the omission of a Lorentz factor.)
