The hour was 2130, mid-evenwatch. Her gang worked around the clock, sleeping in relays, to finish before the sun got so high that heat and radiation kept them inside full-time. Someday, she thought, technology would remove that handicap. (Yes, and it would do something about the damned, clinging, all-begriming dust.) Weariness nagged at her bones. However, at twenty-two years of age, under one-sixth Terrestrial gravity, she could ignore it. She could lose herself in what she did and what she sensed.
Her project was still a jumble of excavations, frameworks, life-support and power systems half installed, men and machines intricately busy. High-piled supplies dwarfed the shelters. Some distance off, the original camp clustered in domes and beehives, not much larger, most living space was underground. There the centrifuge stood idle. The miners were at rest, except for two or three who kept watch over the equipment that did the heavy labor, digging, breaking, and loading. That was two kilometers eastward, almost at the horizon. Sun, shadow, and upflung dust-haze obscured it; occasionally a piece of metal flashed.
The slim pylons of the funicular lifted clear to sight. In double file, widely separated, they marched from the pit, passed within a hundred meters of her, and vanished beyond the southwestern rim of vision. Their cable strands made thin streaks across the sable overhead. A gondola had just been filled with ore and winched aloft to hang by its suspension. The cable was set in motion again. The gondola started its journey through heaven like a spider dangling from a strand. It was off to deliver its burden to the builders of Tychopolis, who would refine and use the metals. They in their turn sent back what the crews here needed. This was the most economical means of bulk transport, given the shortage of vehicles and rugged-ness of the crater floor.
Rugged indeed: hillocks, shelves, boulders, pock-marks, cracks, clefts, a confused and darkling plain. Behind the mine, the uppermost ramparts of a ringwall segment hove into view. The sun having barely cleared them, they remained featurelessly black, their shadow a tar pool. Everywhere else, lesser shadows fingered stone. Stars were drowned in the glare. Soiled white spacesuits, bright-colored badges and tags, scuttled tiny amidst huelessness.
Earth, though, Earth ruled the northern sky. Waned slightly past half phase, the curves of it limned a blue and white marbling, an ocherous blur that was land, a luminance that lingered for a moment after you looked away from it as a dream may linger when first you awaken. Earth was glory enough.
Below it dwelt quietude. Without air, sound dies aborning. Sometimes Dagny’s receiver conveyed a voice, but mainly work proceeded mute, skill set against time. Otherwise she heard air rustle in her recycler and nostrils, blood in her ears.
“Take over,” she told Joe Packer, her second, and went toward the field van. Cabin and laboratory, equipped to travel hundreds of kilometers without recharge and sustain life for weeks, on its eight enormous tires it overtopped the main dome near which it had parked. As she approached, a ladder swung down to the ground, an outer valve opened. The new buildings would allow direct access, airlock to airlock, but as yet visitors must walk across to the entrance.
Dagny quickened her pace. Long since adapted, she moved in her spacesuit almost as easily as in a coverall, low-g lope, exultantly light. A similarly garbed figure appeared above the ladder. “Hi, there!” she called. “Welcome!”
The ground shook beneath her.
The violence went up through her boots and body like a thundercrash.
Almost, she fell. The stumble threw her glance at the sun. Her faceplate darkened to save her eyes and she saw its disc pale in a sudden blindness. She recovered her footing, sight flowed back, she stared northward.
A cloud rose high above yonder horizon. It climbed and climbed, roiled and sooty, thinning at the edges to gray, a smear across Earth. Sparks tumbled from it in long parabolas, as if stars fell.
Meteorite strike! Those were ejecta, flung rocks, shrapnel. Soldiers under fire cast themselves prone— “No. When it came from the sky you were a smaller target on your feet. And you must not run.
