[Pg 57] [Pg 57] Illustrated by Ed Emsh The two spaceship crews were friendly enemies, sitting across the table from each other for their last meal before blastoff. Outside the ports, the sky was nothing but light-streaked blackness, punctured periodically by Earth glare, for Space Station 2 whirled swiftly on its axis, creating an artificial gravity. "Jonner, I figured you the last man ever to desert the rockets for a hot-rod tow-job," chided Russo Baat, captain of the Mars Corporation's gleaming new freighter, Marsward XVIII.

"Times change, Russo," he answered quietly. "Even the Mars Corporation can't stop that." "Is it true that you're pulling five thousand tons of cargo, Captain?" asked one of the crewmen of the Marsward XVIII. "Something like that," agreed Jonner, and his smile broadened.
