"If you don't care about science enough to be interested in it on its own, you shouldn't try to write hard science fiction."
- Frederik Pohl

| Space-Drive | ||
| A means of providing propulsion for a spacecraft. |
As far as I know, the first use of this general term.
| There we shall have plenty of work to do, but on the way we are going to stop at Mars and pick up that very valuable ship of theirs and make a very careful examination for possible new weapons, their system of speed-drive, and their regular space-drive, if it is not the same. |

In case you were curious, and wanted more details:
Compare to Lyle drive from Stranger in a Strange Land (1961) by Robert Heinlein, the
ion drive from Equalizer (1947) by Jack Williamson, the asymptotic drive from Imperial Earth (1976) by Arthur C. Clarke and the gravity drive from Star Ship (1950) by Poul Anderson.
Their regular drive is a molecular drive with lead disintegration apparatus for the energy, cosmic ray absorbers for the heating, and a drive much like ours. Their speed drive is a time distortion apparatus, I'll wager. Time distinction offers an easy solution of speed. All speed is relative--relative to other bodies, but also to time-speed. But we'll see.
