Spacemen, Go Home

When the moonship "Tycho III" comes into the landing pit at the New Mexico Spaceport, Andy Marlow has his first look in more than a year at the planet Earth. Instead of proud launching gantries and gleaming ships, he sees empty firing pits and the broken hulks of a few old spacetubs. Earth's brief two hundred years in space is now past history; man has been exiled for a violation of inter-galactic law. A short time after landing, Andy and his best friend despondently accept a mysterious job offer that takes them to a secret spaceport deep in the jungles of Central America. Here a ruthless ex-space captain, Reed Ballinger, plans to blast his way back into the galaxy. Andy, torn between loyalty to his friend and a growing awareness that Ballinger's way means war, finally flees the spaceport. He joins Project Nobel, a brilliant and dangerous scheme to thwart Ballinger and to convince the Star Brain, the machine that rules the galaxy, that Earth deserves to regain its place in space.
