up.”
“I know that, thanks,” Yuri said heavily. “Since one of them is ours.”
They talked of bits of business, and how they were all coping.
It was as if Mars’s last summer had been cut drastically short.
The sun had vanished two months before what should have been midsummer, and the planet’s terminal winter had begun.
In a way it didn’t make much difference here at the pole, where it had been dark half the time anyhow. Myra’s main loss was the regular download from Earth of movies and news, and letters from home. She didn’t miss Earth itself as much as she missed the mail.
But if there was a winter routine to fall back on here at Wells, they weren’t so used to darkness down at Lowell, near the equator, and it was a shock when the air started snowing out there. They had none of the equipment they needed to survive. So Yuri and Myra had loaded up one of the pole station’s two specialized snowplow rovers with sublimation mats and other essentials. They left one rover at Lowell for the crew’s use there, and then drove the other rover all the way back to Wells. That journey, a quarter of the planet’s circumference each way through falling dry-ice snow, had been numbing, depressing, exhausting. Myra and Yuri hadn’t left the environs of the base since.
“We’ll speak again,” Paula said. “Take care.” Her image disappeared.
Myra looked at Yuri. “So that’s that.”
“Back to work,” he said.
“Coffee first?”
“Give me an hour, and we’ll break the back of some of the day’s chores.”
“Okay.”
The routine work had got a lot harder since the final evacuation.
Without the scheduled resupply and replacement drops it wasn’t just the nuke that was failing but much of the other equipment as well. And now there were only two of them, in a base designed for ten, and Myra, though she was a quick learner, wasn’t experienced here.
However Myra had thrown herself into the work. This morning she tended clogging hydroponic beds, and cleaned out a gunged-up bioreactor, and tried to figure out why the water extraction system was failing almost daily. She also had work to do with the AI, managing the flood of science data that continued to pour in from the SEPs and tumbleweed balls and dust motes, even though the sensor systems were steadily falling silent through various defects, or were simply getting stuck in the thickening snow.
Mostly the AI was able to work independently, even setting its own science goals and devising programs to achieve them. But today was PPP day, planetary protection, when she had to make her regular formal check to ensure the environment was properly sampled in a band kilometers wide around the station, thus monitoring the slow seepage of their human presence into the skin of Mars. There was even a bit of paper she had to sign, for ultimate presentation to an agency on Earth. The paper was never going to get to Earth, of course, but she signed it anyway.
After an hour or so she had the AI hunt for Yuri. He was supposed to be out in the drill rig tent, mothballing equipment that had been shut down for the final time, thus fulfilling a promise he had made to Hanse Critchfield. In fact he was in Can Six, the EVA station.
She made some coffee, and carried it carefully through the locks to Six. She kept a lid on the cups; she still hadn’t quite got used to one-third-G coffee sloshes.
She found Yuri kneeling on the floor of Six. He had gotten hold of a Cockell pulk, a simple dragging sled; adapted for Martian conditions it was fitted with fold-down wheels for running over basalt-hard water ice. He was piling up this little vehicle with a collapsed tent, food packets, bits of gear that looked to have been scavenged from life support.
She handed him his coffee. “So what now?”
He sat back and sipped his drink. “I’ve got an unfulfilled ambi-tion. I’ve got many, actually, but this one’s killing me.”
“Tell me.”
“An unsupported solo assault on the Martian north pole. I always planned to try it myself. I’d start at the edge of the permanent cap, see, just me and an EVA suit and a sled. And I’d walk, dragging the sled all the way to the pole. No drops, no pickup, nothing but me and the ice.”
“Is that even possible?”
“Oh, yes. It’s a thousand kilometers tops, depending on the route you take. The suit would slow me down — and no suit we’ve got is designed for that kind of endurance and mobility; I’d have to make some enhancements. But remember, with one-third G I can haul three times as much as I could in Antarctica, say four hundred kilograms. And in some ways Mars is an easier environment than the Earth’s poles. No blizzards, no white-outs.”
“You’d have to carry all your oxygen.”
“Maybe. Or I could use one of these.” He picked up some of his life-support gadgets, a small ice-collector box, an electrolysis kit for cracking water into oxygen and hydrogen. “It’s a trade-off, actually.
The kits are lighter than oxygen bottles would be, but using them daily would slow me down. I know it’s a stunt, Myra. But it’s one
“You’ve got some mission designing to do, then.”
“Yes. I could figure it all out during the winter. Then when the summer comes, I could pick some period when Earth is above the horizon to try it. I could get the gear together and try it out on the ice around the base. The darkness wouldn’t make any difference to that.” He seemed pleased to have found this new project. But he looked up at her, uncertain. “Do you think I’m crazy?”
“No crazier than any of us. I mean, I don’t think I believe in May 12. Do you? None of us
“Yes. But—”
“Let’s not talk about it,” she said firmly. She knelt down with him on the cold floor. “Show me how you’re going to pack this stuff up. How would you eat? Unpack the tent twice a day?”
“No. I thought I’d unpack it in the evening, and eat overnight and in the morning. Then I could have some kind of hot drink through the suit nozzle during the day…”
Talking, speculating, fiddling with the bits of kit, they planned the expedition, while the frozen air of Mars gathered in snowdrifts around the stilts of the station modules.
61: Grasper
It was Grasper who first noticed the change in the Eye.
She woke up slowly, as always clinging to her ragged dreams of trees. Suspended between animal and human, she had only a dim grasp of future and past. Her memory was like a gallery hung with vivid images — her mother’s face, the warmth of the nest where she had been born. And the cages. Many, many cages.
She yawned hugely, and stretched her long arms, and looked around. The tall woman who shared this cave still slept. There was light on her peaceful face.
Light?
Grasper looked up. The Eye was shining. It was like a miniature sun, caught in the stone chamber.
Grasper raised a hand toward the Eye. It gave off no heat, only light. She stood and gazed at the Eye, eyes wide, one arm raised.
Now there was something new again. The glow of the Eye was no longer uniform: a series of brighter horizontal bands straddled an underlying grayness, a pattern that might have reminded a human of lines of latitude on a globe of the Earth. These lines swept up past the Eye’s “equator,” dwindling until they vanished at the north
