The Planet Strappers

A Million Miles Beyond the Moon... ... Nelson and Ramos sped on toward Mars in their tiny plastic-bubble spacecraft. They were on the alert—it didn't pay to take anything for granted in the Big Vacuum.... The way between the worlds was mostly empty space—except for the outlaws of the void who drifted, patiently and vengefully waiting for a victim, then struck!

Air puffed out ... and Nelson and Ramos were fighting for their lives... ... A Million Miles Beyond the Moon!
