 Where was the space craft heading in the end?
The glowing semi-disk of Jupiter was more than half a million miles distant. Maybe they live soft back on Earth since the mines and the Jovian satellite colonies grew; but they were out here in the beginning, most of them. It had been built for Ganymede, but not for Jeffers. His contract guaranteed a pilot's rating, but someone had neglected to specify the type of craft to be piloted. He soon found that there was nothing for him to do but hang around the garage in case a spaceship should land. Sometimes there's no reason but them for sending a ship back with a crew instead of in an economy orbit. Under a portable, double-chambered plastic dome blown up outside the ship's airlock, a crewman helped him load two trunks and a collection of bags into the tractor. They found they could send back loaded ships by 'automatic' flight—that is, a long, slow, economical orbit and automatic signalling equipment. Then they're boarded approaching Earth's orbit and landed by pilots who don't have to waste their time making the entire trip." He followed the signals of a spacesuited member of the port staff and maneuvered out of the dome. Then he headed the tractor across the frozen surface of Ganymede toward the permanent domes of the city. When the rock and ice are set to sliding, they come at you practically horizontally. "I'm retiring in six months if I'm still alive," he said bravely, edging the tractor into the airlock at their destination.
