"People ask me how I do research for my science fiction. The answer is, I never do any research. I just enjoy reading the stuff, and some of it sticks in my mind and fits into the stories."

Here is a bit more description:
"The discovery of jovium initiated the commercial exploitation of the far planets. It initiated also a race in spatial armament between Mars and Earth, that so far has been a dead heat."
Single-fueled rockets, also called monopropellant rockets, actually exist. The most commonly used monopropellant is hydrazine (N2H4), a chemical which is a strong reducing agent. The most common catalyst is granular alumina coated with iridium.
Compare to the materials used in Bussard ramjets from Larry Niven's 1976 novella World out of Time and protonite from Jack Williamson's 1931 story Twelve Hours to Live.
