From the grand master of science fiction comes this classic story about pioneers at the dawn of space exploration.

Ross Jenkins, Art Mueller, and Morris Abrams are not your average high schools students. While other kids are cruising around in their cars or playing ball, this trio, known as the Galileo Club, is experimenting with rocket fuels, preparing for their future education at technical colleges.

Art's uncle, the nuclear physicist Dr. Donald Cargraves, offers them the opportunity of a lifetime: to construct and crew a rocket that will take them to the moon. Cargraves believes their combined ingenuity and enthusiasm can actually make this dream come true—but there are those who don't share their dream and who will stop at nothing to keep their rocket grounded.
