The story of a military recruit entering into a space program seems commonplace in science fiction these days. There have been any number of attempts, from Marko Kloos’ Terms of Enlistment to Ender’s Game, but the original “Space Cadet” novel was by Robert Heinlein in 1948.
This book was one of Heinlein’s “Juveniles“. These were books meant to appeal to a teenage boy audience and inspire scientific ideas. Interestingly, he also wrote three stories for girls with a female protagonist, but that’s for another day.
The main character is Matt Dodson, but he often takes a secondary role. In the beginning, we learn about the Patrol and their efforts in our solar system. We learn about aliens and colonists and the state of governments in the future. It’s explained early on that the Patrol exists to make sure war never breaks out again.
However, things are a little more confusing than that.
Space Cadet is one of those books that grabs you half-way through and forces you to keep reading. I was hooked at that point and refused to put it down. The part on Venus is a little odd, and almost jarring. It was interesting to see the characters interact in a situation like that, but the main character stopped feeling like the main character at that point. Also, the ending felt a little underwhelming.
Ultimately, I would recommend this for anyone who’s interested in some of Heinlein’s earlier work; it was the second of his “Juveniles”, which culminated in Starship Troopers as his thirteenth attempted entry.
