Red Mars (Mars Trilogy, #1) - Kim Stanley Robinson Page 0,110

and the pile of scrap. The truck had landed on its right side, and the left side was deformed but recognizable. Okakura climbed several steps up the wreckage, then pointed at a black area behind the left front tire. John followed him up, scraped at the metal with the claw on his right glove’s forefinger. The black came away like soot. Ammonium nitrate explosion. The body of the truck was bent in there as if hammered. “A good-sized charge,” John observed.

“Yes,” Okakura said, and cleared his throat. He was frightened, that was sure. Well, the first man on Mars had almost been killed while in his care; and himself too, of course, but who knew which would scare him more? “Enough to push truck off road.”

“Well, like I said, there’s been some sabotage reported.”

Okakura was frowning through his faceplate. “But who? And why?”

“I don’t know. Anyone in your team seem to be having any psychological difficulties?”

“No.” Okakura’s face was carefully blank. Every group larger than five had someone experiencing difficulties, and Okakura’s little industrial town had a population of 500.

“This is the sixth case I’ve seen,” John said. “Although none so close up.” He laughed. The image of the birdlike dot in the pink sky came back to him. “It would have been easy for someone to attach a bomb to a truck before it came down. Detonate it with a clock or an altimeter.”

“Reds, you mean.” Okakura was looking relieved. “We have heard of them. But it is …” He shrugged. “Crazy.”

“Yes.” John climbed gingerly off the wreck. They walked back across the floor of the shaft to the car they had come down in. Okakura was on another band, talking to people up top.

John stopped by the central pit to have a final look around. The sheer size of the shaft was hard to grasp; the muted light and vertical lines reminded him of a cathedral, but all the cathedrals ever built would have sat like dollhouses at the bottom of this great hole. The surreal scale made him blink, and he decided he had tilted his head back too long.

They drove up the road inscribed in the side wall to the first elevator, left the car and got in the cage. Up they went. Seven times they had to get out and walk across the wall road to the bottom of the next elevator. The ambient light grew to something more like ordinary daylight. Across the shaft he could see where the wall was scored by the double spiral of the two roads: thread-marks in an enormous screw hole. The shaft’s bottom had disappeared into the murk, he couldn’t even make out the truck.

In the last two elevators they ascended through regolith; first the megaregolith, which looked like cracked bedrock, and then the regolith proper, its rock and gravel and ice all hidden behind a concrete retainer, a smooth curved wall that looked like a dam, and was angled so far back that the final elevator was actually a cog rail train. They cranked up the side of this enormous funnel—Big Man’s bathtub drain, Okakura had said on the way down—and came finally to the surface, out into the sun.

Boone got out of the cog train and looked back down. The regolith retainer looked like the inner wall of a very smooth crater, with a two-laned road spiraling down it, but the crater had no floor. A mohole. He could see down the shaft a little way, but the wall was in shadow, and only the road spiraling down picked up any light, so that it appeared to be something like a freestanding staircase, descending through empty space to the planet’s core.

Three of the giant dump trucks ground slowly up the last stretch of the road, full of black boulders. These days it took them five hours to make the trip from the bottom of the shaft, Okakura said. Very little supervision, like most of the project, in both manufacture and operation. The inhabitants of the town only had to see to programming, deployment, maintenance, and troubleshooting. And, now, security.

The town, called Senzeni Na, was scattered over the floor of Thaumasia Fossae’s deepest canyon. Nearest to the hole was the industrial park; here most of the excavation equipment was manufactured, and the rock from the hole processed for its trace amounts of valuable metals. Boone and Okakura stepped into the rim station, changed out of their pressure suits into coppery jumpers, and entered one of the clear
