The related works category for the Hugo’s is non-fiction related to science fiction. Ken Burnside’s article gives us the inside info on thermodynamics and how this limits space travel and course changes. He explains electrodynamic rockets, thermodynamic rockets and solar sails as propulsion systems and orbital mechanics as a constraint. He then reviews how to apply this information to write accurate hard science fiction. The space opera fans are not going to be pleased, but this is good, solid info for the serious writer. Four stars.
