A stupendous flash of light blazed up from the tracks where the loading platform had been. A bloodred afterimage split his vision in two halves; as it was pulsing back to a less vivid vertical blob, rocks began crashing down around them, kicking up puffs of dust that moved like splashed water. They both cried out, although Wahram had no idea what either said; then Swan was crying, “Get down, guard your head!” and tugging at his arm. Wahram kneeled next to her and put an arm around her shoulders; she seemed to be trying to put her arms over his helmet while ducking hers against his chest. Looking over her, he saw that the tracks where the platform had been had disappeared in a big ball of dust, and the very top of the dust cloud was now high enough to be up in the sunlight. The brilliant yellow of the sunlit part of the cloud illuminated the land around it like a beacon of fire. The land at the foot of the cloud was glowing with a light of its own; it appeared to be a pool of smoking lava.

“A meteor,” he said stupidly.

Swan was talking on the common band. A few more rocks fell on the land around them, invisible until announced by an explosion of dust. It looked like the land was exploding, as if mines were going off. Occasionally a falling rock was hot and looked like a shooting star. Some ember blinks were still up there flying among the stars. They would get hit or they wouldn’t: an awful feeling. Guarding their helmets did not seem like it was going to do much good.

Dust flew up over them, fell back to land in lazy sheets and veils. Gray topped by yellow; but when the top of the dust cloud fell back below the horizontal beams of approaching sunlight, they were plunged into the darkness of Mercurial night, with only the distant lit crater wall to illuminate them with its reflection. Red bars still pulsed vertically in the middle of Wahram’s sight. It seemed much dimmer than it had before.

“There’s a group of sunwalkers just south of here, up under the crater wall,” Swan said grimly. She asked a question on the common band. “One of them’s been hit, and they need help. Come on.”

He followed her away from the tracks, feeling blind and confused. “Was it a meteor strike?”

“Looks like it. Although the tracks have a detect-and-deflect system, so I don’t know what happened. Come on, we’ve got to hurry! I want to get back to the city. It’s… ohhh…” She groaned as the realization appeared to strike her that the city was doomed. “No!” she cried as she dragged him southward. “No, no, no, no, no, no, no.” Over and over as they stumbled along. Then: “How could it be.”

He couldn’t tell if it was a rhetorical question. “Don’t know,” he said. She tugged at him and he kept his eyes on the ground to keep from kicking a rock and falling. Rocks littered the land. He tried to remember what he had seen; had it been a flash? From above? Hadn’t it risen? No-a downward motion. He closed his eyes, but the red bar and light red clouds still bounced around on the black backdrop of the insides of his eyelids. He opened his eyes, glanced at Swan. Later perhaps they could review her qube’s visual record, assuming it kept one. She was muttering now in the irritated tone of voice she seemed to use only when addressing it.

She led him around a hillock, and when they had cleared it, they spotted a group of three people in spacesuits, all three walking, which was good to see, but with one holding one arm with the other hand, and walking awkwardly as a result. The other two flanked this one, helping or trying to.

“Hey!” Swan said on the common band, and they looked up and saw them approaching. One waved. Swan and Wahram joined them a few minutes later.

“How are you?” Swan said.

“Happy to be alive,” said the one holding an arm. “I got hit on the arm!”

“I can see. Let’s get back to the city.”

“What happened?”

“A meteor hit the tracks, it looked like.”

“How could that be?”

“I don’t know. Come on!”

Without further discussion the five of them began walking at speed toward the tracks, striding along in a Martian lope that made the best of the local g. Wahram was all right at it because of his time on Titan, which was about half as heavy as this, but similar enough. Together they bounded down the mild slope, angling eastward to intercept the city as soon as possible. There was a strange keening in Wahram’s ear, an animal moan of distress; at first he thought it was the hurt sunwalker, but then realized it was Swan. Of course it was her city, her home.

They came over a rise that gave them a view of the top half of the city’s dome, bulging over the horizon like the blue bubble of a pocket universe. The city appeared to be moving still. “The tracks ahead of it are damaged,” he said.

“Yes, of course!”

“Is there a way for it to get past a section of broken track?”

“No! How would that work?”

“I don’t know, I’m just… wondering. It seems like most support systems try to avoid criticalities.”

“Of course. But the tracks are protected, there’s an anti-meteor system!”
