The glow, he knew, was a fluorescent, electronic discharge in the radioactive gases jetting from the rockets of the racing ship...
The idea behind a reaction-motor is Newton's Third Law of Motion, which decrees that for every action, there is an equal and opposite reaction. For a spacecraft to move forward, you must throw matter out the other end.
Compare to the reactionless drive idea, which encompasses the various hyperdrives that allow a ship to move from one point to another in space, without traversing the space in between. See the inertialess drive from 'Doc' Smith's 1934 novel Triplanetary.
