Plot summaryEdit

A coming-of-age story that follows Andrew Jackson Libby (here nicknamed Pinky, for his red hair, but later nicknamed Slipstick), a boy from Earth with extraordinary mathematical ability[2] but meager education. Finding few opportunities on Earth, he joins the Cosmic Construction Corps, a future military-led version of the US Depression-era Civilian Conservation Corps employing out-of-work youth to colonize the Solar System. With a group of other inexperienced young men he is assigned to a ship traveling to the asteroid belt where their task is to move an asteroid into a more convenient orbit between Mars and Earth. Pinky comes to the Captain's attention during the process of blasting holes in the asteroid for rocket engines when Pinky realizes that a mistake has been made in calculating the size of the charge, preventing a catastrophic blast. He is assigned to the ship's astrogation computer. During the trip back to Earth, the computer malfunctions and Libby takes over, performing all the complex calculations in his head. The asteroid is settled successfully into its final orbit.

"Slipstick" Libby became one of Heinlein's recurring characters, and would later appear in several works associated with Lazarus Long, among them Methuselah's Children and The Cat Who Walks Through Walls.

The short story includes one of the first examples of the phrase "space marine".
