The Secret of Saturn's Rings is a science-fiction novel by Donald A. Wollheim and was first published in the United States by the John C. Winston Company in 1954. This is the first of three novels that Wollheim wrote for the Winston Company, the other two being The Secret of the Martian Moons (1955) and The Secret of the Ninth Planet (1959). This is also one of the thirty-five juvenile novels that comprise the Winston Science Fiction set, which novels were published in the 1950s for a readership of teen-aged boys. The typical protagonist in these books was a boy in his late teens who was proficient in the art of electronics, a hobby that was easily available to the readers. It was his proficiency in that art that enabled Bruce Rhodes to detect an act of sabotage on his father's rocket ship. Plot On the day of his graduation from high school Bruce Rhodes finds his classmates shunning him. He discovers that his father, Dr. Emanuel Rhodes, who has worked for the Terraluna Corporation for thirty years, most of that time as head of research, has been fired and the corporation is now smearing him. With a borrowed United Nations exploration ship, Dr. Rhodes intends to lead an expedition to Saturn, farther from Earth than anyone has ever gone. Dr. Rhodes explains that he has discovered that a nuclear-explosion-driven mining machine that he invented for Terraluna will actually blast the moon apart, sending debris raining down onto Earth and destroying civilization. Terraluna's executives had dismissed him (in both senses of the term) as a crackpot, so he went to the United Nations. Requiring additional proof of his hypothesis, the United Nations has loaned him a ship so that he can go to Saturn to determine whether the planet's rings are the remains of an exploded moon. With the other three members of the crew – able spaceman Arpad Benz (who will work with Bruce), astrogator Frank Garcia, and pilot Kurt Jennings – Bruce and his father board the ship and prepare for liftoff. The ship is launched up the side of a mountain, much of the initial boost being provided by a series of magnetic rings (similar to the ringroad that Robert Heinlein described in Starman Jones). Soon they're on their way to the moon to top off their fuel tanks, knowing that Terraluna intends to use every filthy,
