THE SNOWBANK ORBIT BY FRITZ LEIBER Earth could not stop the Enemy's remorseless advance from outer space. Neither could the Enemy! [Transcriber's Note: This etext was produced from Worlds of If Science Fiction, September 1962.

The Bull is her coronet and the Scorpion her footstool. Dear blowzy old bitch-planet, swollen and pale and cold, mad with your Shakespearean moons, white-mottled as death from Venerean Plague, spinning on your side like a poisoned pregnant cockroach, rolling around the sun like a fat drunken floozie with green hair rolling on the black floor of an infinite bar-room, what a sweet last view of the Solar System you are for a cleancut young spaceman.... Grunfeld chopped off that train of thought short. He was young and the First Interstellar War had snatched him up and now it was going to pitch him and twenty other Joes out of the System on a fast curve breaking around Uranus—and so what! He shivered to get a little heat and then applied himself to the occulted star he was tracking through Prospero's bridge telescope. The star was a twentieth planetary diameter into Uranus, the crosslines showed—a glint almost lost in pale green. That meant its light was bulleting 1600 miles deep through the seventh planet's thick hydrogen atmosphere, unless he were seeing the star on a mirage trajectory—and at least its depth agreed with the time since rim contact. At 2000 miles he lost it. That should mean 2000 miles plus of hydrogen soup above the methane ocean, an America-wide layer of gaseous gunk for the captain to play the mad hero in with the fleet. Grunfeld didn't think the captain wanted to play the mad hero. The captain hadn't gone space-simple in any obvious way like Croker and Ness. And he wasn't, like Jackson, a telepathy-racked visionary entranced by the Enemy. Worry and responsibility had turned the captain's face into a skull which floated in Grunfeld's imagination when he wasn't actually seeing it, but the tired eyes deep-sunk in the dark sockets were still cool and perhaps sane. But because of the worry the captain always wanted to have the last bit of fact bearing on the least likely maneuver, and two pieces of evidence were better than one.
