Exploring the Outer Planets

In 1977, NASA launched the space probes Voyager 1 and Voyager 2 to explore Jupiter, Saturn, Uranus, and Neptune. This book tells of what was known about those planets and their moons before the Voyager missions, as well as what Voyager discovered about those planets and their moons. This book is written for the middle-grade reader, and can be enjoyed by readers age 12 and up.

A word from the Author

I became interested in astronomy in second grade, when my teacher put up a bulletin board about the solar system. I went to the library and checked out every astronomy book I could and read it. When I finished high school, I went on to get a bachelor's degree in physics. After that, I went to the graduate school of astronomy at Indiana University, where I was an associate instructor of astronomy for one year. Even though I did not get my master's degree, I have maintained an interest in astronomy and keep up with the field by reading articles about astronomy on a regular basis.

Joan Marie Verba


Joan Marie Verba has written a wonderful tale of the craft that have gone where no one has gone before. . . . Geared toward the intermediate student, the book is well written . . . and brimful of information.

Verba’s account is crammed with information about the moons, rings, atmospheres, temperatures, and orbits of these planets . . . the large quantity of information makes this a worthwhile resource. . . .

Verba gives a concise but fairly thorough description of the Voyager project from conception through the completion of the probes’ photographic mission. ...this is a good account of the flights of Voyager 1 and 2 and what we learned from them.
