Lightspeed: Year One

One of the snowflake patterns lay mostly undamaged, within Lvov’s reach. She crouched and peered at it. The flake was perhaps a foot across. Internal structure was visible within the clear ice as layers of tubes and compartments; it was highly symmetrical, and very complex. She said to Cobh, “This is an impressive crystallisation effect. If that’s what it is.” Gingerly she reached out with thumb and forefinger, and snapped a short tube off the rim of the flake. She laid the sample on her desk. After a few seconds the analysis presented. “It’s mostly water ice, with some contaminants,” she told Cobh. “But in a novel molecular form. Denser than normal ice, a kind of glass. Water would freeze like this under high pressures—several thousand atmospheres.”

“Perhaps it’s material from the interior, brought out by the chthonic mixing in that region.”

“Perhaps.” Lvov felt more confident now; she was intrigued. “Cobh, there’s a larger specimen a few feet further away.”

“Take it easy, Lvov.”

She stepped forward. “I’ll be fine. I—”

The surface shattered.

Lvov’s left foot dropped forward, into a shallow hole; something crackled under the sole of her boot. Threads of ice crystals, oddly woven together, spun up and tracked precise parabolae around her leg.

The fall seemed to take an age; the ice tipped up towards her like an opening door. She put her hands out. She couldn’t stop the fall, but she was able to cushion herself, and she kept her faceplate away from the ice. She finished up on her backside; she felt the chill of Pluto ice through the suit material over her buttocks and calves.

“ . . . Lvov? Are you okay?”

She was panting, she found. “I’m fine.”

“You were screaming.”

“Was I? I’m sorry. I fell.”

“You fell? How?”

“There was a hole, in the ice.” She massaged her left ankle; it didn’t seem to be hurt. “It was covered up.”

“Show me.”

She got to her feet, stepped gingerly back to the open hole, and held up her data desk. The hole was only a few inches deep. “It was covered by a sort of lid, I think.”

“Move the desk closer to the hole.” Light from the desk, controlled by Cobh, played over the shallow pit.

Lvov found a piece of the smashed lid. It was mostly ice, but there was a texture to its undersurface, embedded thread which bound the ice together.

“Lvov,” Cobh said. “Take a look at this.”

Lvov lifted the desk aside and peered into the hole. The walls were quite smooth. At the base there was a cluster of spheres, fist-sized. Lvov counted seven; all but one of the spheres had been smashed by her stumble. She picked up the one intact sphere, and turned it over in her hand. It was pearl-grey, almost translucent. There was something embedded inside, disc-shaped, complex.

Cobh sounded breathless. “Are you thinking what I’m thinking?”

“It’s an egg,” Lvov said. She looked around wildly, at the open pit, the egg, the snowflake patterns. Suddenly she saw the meaning of the scene; it was as if a light had shone up from within Pluto, illuminating her. The “snowflakes” represented life, she intuited; they had dug the burrows, laid these eggs, and now their bodies of water glass lay, dormant or dead, on the ancient ice . . .

“I’m coming down,” Cobh said sternly. “We’re going to have to discuss this. Don’t say anything to the inner System; wait until I get back. This could mean trouble for us, Lvov.”

Lvov placed the egg back in the shattered nest.

She met Cobh at the crash scar. Cobh was shovelling nitrogen and water ice into the life-support modules’ raw material hopper. She hooked up her own and Lvov’s suits to the modules, recharging the suits’ internal systems. Then she began to carve GUTdrive components out of the flitter’s hull. The flitter’s central Grand Unified Theory chamber was compact, no larger than a basketball, and the rest of the drive was similarly scaled. “I bet I could get this working,” Cobh said. “Although it couldn’t take us anywhere.”

Lvov sat on a fragment of the shattered hull. Tentatively, she told Cobh about the web.

Cobh stood with hands on hips, facing Lvov, and Lvov could hear her sucking drink from the nipples in her helmet. “Spiders from Pluto? Give me a break.”

“It’s only an analogy,” Lvov said defensively. “I’m an atmospheric specialist, not a biologist.” She tapped the surface of her desk. “It’s not spider-web. Obviously. But if that substance has anything like the characteristics of true spider silk, it’s not impossible.” She read from her desk. “Spider silk has a breaking strain twice that of steel, but thirty times the elasticity. It’s a type of liquid crystal. It’s used commercially—did you know that?” She fingered the fabric of her suit. “We could be wearing spider silk right now.”

“What about the hole with the lid?”

“There are trapdoor spiders in America. On Earth. I remember, when I was a kid . . . The spiders make burrows, lined with silk, with hinged lids.”

“Why make burrows on Pluto?”
