vanish.... Unless, Grunfeld told himself ... unless the fleet shed its velocity by ramming the gaseous bulk of Uranus. This idea of atmospheric braking on a grand scale had sounded possible at first suggestion, half a year ago—a little like a man falling off a mountain or from a plane and saving his life by dropping into a great thickness of feathery new-fallen snow. Supposing her solar jet worked out here and she had the reaction mass, Prospero could have shed her present velocity in five hours, decelerating at a comfortable one G. But allowing her 12,000 miles of straight-line travel through Uranus' frigid soupy atmosphere—and that might be dipping very close to the methane seas blanketing the planet's hypothetical mineral core—Prospero would have two minutes in which to shed her velocity. Two minutes—at 150 Gs. Men had stood 40 and 50 Gs for a fractional second. But for two minutes.... Grunfeld told himself that the only surer way to die would be to run into a section of the Enemy fleet. According to one calculation the ship's skin would melt by heat of friction in 90 seconds, despite the low temperature of the abrading atmosphere. The star Grunfeld had been waiting for touched the hazy rim of Uranus. He drifted back to the eyepiece and began to follow it in as the pale planet's hydrogen muted its diamond brilliance. III In the aft cabin, lank hairy-wristed Croker pinned another blanket around black Jackson as the latter shivered in his trance. Then Croker turned on a small light at the head of the hammock. "Captain won't like that," plump pale Ness observed tranquilly from where he floated in womb position across the cabin. "Enemy can feel a candle of our light, captain says, ten million miles away." He rocked his elbows for warmth and his body wobbled in reaction like a polly-wog's. "And Jackson hears the Enemy think ... and Heimdall hears the grass grow," Croker commented with a harsh manic laugh. "Isn't an Enemy for a billion miles, Ness." He launched aft from the hammock. "We haven't spotted their green since Saturn orbit. There's nowhere for them." "There's the far side of Uranus," Ness pointed out. "That's less than ten million miles now. Eight. A bare day. They could be
