Tom Corbett is the main character in a series of Tom Corbett — Space Cadet stories that were depicted in television, radio, books, comic books, comic strips, coloring books, punch-out books and View-Master reels in the 1950s. The stories followed the adventures of Tom Corbett, Astro, and Roger Manning, cadets at the Space Academy as they train to become members of the elite Solar Guard. The action takes place at the Academy in classrooms and bunkroom, aboard their training ship the rocket cruiser Polaris, and on alien worlds, both within our solar system and in orbit around nearby stars.

The Tom Corbett universe partook of pseudo-science, not equal to the standards of accuracy set by John W. Campbell in the pages of Astounding. And yet, by the standards of the day, it was much more accurate than most media science fiction. Mars was a desert, Venus a jungle, and the asteroids a haunt of space pirates, but at least planets circled suns and there was no air in space. Contrast this with The Twilight Zone, years later, where people could live on asteroids wearing ordinary clothes, or Lost in Space, years after that, where a spaceship could be passing "Jupiter and Andromeda" at the same time. Before Star Trek, Tom Corbett — Space Cadet was the most scientifically accurate series on television, in part due to official science advisor Willy Ley, and later due to Frankie Thomas. Thomas read up on science and everyone on the set turned to him for advice on matters scientific.
