 How was Quest able to survive and grow up on Jupiter?
50 THE JUPITER WEAPON By CHARLES L. FONTENAY Trella feared she was in for trouble even before Motwick's head dropped forward on his arms in a drunken stupor. It was a squalid saloon in the rougher section of Jupiter's View, the terrestrial dome-colony on Ganymede. A woman could not possibly make her way through these streets alone to the better section of town, especially one clad in a silvery evening dress. Perhaps she could call one of Motwick's friends; she had no one on Ganymede she could call a real friend herself. Trella swung with her whole body, and slapped him so hard he nearly fell from his chair. The dark man moved in on Trella again as Kregg overtook his quarry and swung a huge fist like a sledgehammer. The dark man, who had grabbed Trella's arm, released her and ran for the door. The gravity of Ganymede was hardly more than that of Earth's moon, but the way the man picked up the limp Motwick with one hand and tossed him over a shoulder was startling: as though he lifted a feather pillow. He followed Trella out the door of the Golden Satellite and fell in step beside her. The transparent dome of Jupiter's View was faintly visible in the reflected night lights of the colonial city, but the lights were overwhelmed by the giant, vari-colored disc of Jupiter itself, riding high in the sky. “No one has ever landed on Jupiter. But his ship was drawn into Jupiter and lost.”
