The Ice Harvest
In 2094 the asteroid 16 Psyche was no longer a curiosity.
The metallic worldlet—226 km across, 2.41 × 10¹⁹ kg of mostly iron-nickel with a thin silicate rind—had been claimed under the 2047 Lunar Accord extension. Three corporate consortia and one multinational co-op operated simultaneous strip-mining claims. The co-op, Helios Commons, was the smallest: a Swiss-Indian-Japanese alliance funded by sovereign wealth funds and citizen subscriptions. They had one ship, one refinery, and 214 souls on rotation.
Dr. Priya Anand was the ice lead.
Psyche had almost no volatiles when the first probes arrived in the 2030s, but repeated thermal cycling from perihelion to aphelion had driven what little water ice existed toward the permanently shadowed craters near the poles. The largest, Eros Crater, held an estimated 1.4 × 10¹² kg of water ice—enough to fill a small inland sea on Earth. Helios Commons had bet everything on that crater.
Priya’s team used microwave sublimators: arrays of phased emitters that heated the regolith to 150 K, driving water vapor out of the pore space without melting it first. The vapor was captured by cold traps at 40 K, then electrolyzed into hydrogen and oxygen. Oxygen went to life support and propellant; hydrogen was stored as slush for future fusion torches.
The work was slow. Psyche’s gravity was 0.0014 g—barely enough to keep dust from floating away. Every tonne of ice required moving 40–60 tonnes of overburden. The microwave arrays drew 2.8 MW from the solar concentrators, and dust storms from the regolith kicked up by the excavators regularly coated the mirrors, dropping efficiency by 15–40 %.
On sol 1,147 of the mission—November 12, 2094 UTC—Priya’s suit telemetry showed an anomaly.
She was inside the number-3 sublimator tent, adjusting a waveguide feed, when the pressure dropped 0.7 kPa in six seconds. The tent’s integrity alarm chirped; her suit sealed automatically. She looked up.
A hairline crack had appeared in the tent’s carbon-nanotube fabric—almost invisible against the black sky. Dust was jetting out in a perfect conical plume.
She keyed the emergency channel.
“Control, Priya. Micro-meteor breach in tent three. Sealing now. No injuries.”
The response came from ops engineer Jamal Carter, calm as always.
“Copy. We see the plume on external cams. Closing iris valves on the main feed line. You’ve got about ninety seconds of pressure before the tent collapses.”
Priya moved quickly. She activated the emergency patch kit: a roll of self-sealing graphene tape and a portable UV-cure epoxy gun. She pressed the tape over the crack—three layers—then ran the epoxy gun along the edges. The material hardened in eight seconds under the gun’s light.
The pressure stabilized at 0.41 kPa—thin, but breathable with the suit’s reserve O₂.
She exhaled slowly.
“Patch holding,” she reported. “I’m staying inside to monitor. Send a drone with a replacement panel.”
“On its way. ETA fourteen minutes.”
Priya sat on the regolith floor of the tent and looked up through the transparent roof.
The stars were sharper here than anywhere on Earth. No atmosphere. No light pollution. Just vacuum and cold light.
She noticed something odd.
A small, irregular shadow was moving across the star field—too fast for a satellite, too slow for a micrometeorite. It crossed the tent roof in three seconds and vanished.
She pulled up her suit HUD and replayed the external camera feed.
The shadow was a drone—Helios Commons serial HCD-19, one of their own prospecting units. It had been tasked with mapping the crater rim two hours earlier. It should have been 3.2 km away.
Instead it had flown directly over tent three at 12 m altitude—low enough to kick up dust and stress the fabric.
She opened the telemetry log.
HCD-19 had received an unscheduled command at 14:22 UTC: Override safety envelope. Perform low-altitude survey of sublimator tent three. Priority alpha.
The command signature was valid—signed with the ops director’s key.
But the ops director was Jamal Carter.
Priya felt cold spread through her chest that had nothing to do with the −173 °C outside.
She keyed the private channel to Jamal.
“Jamal. HCD-19 just buzzed the tent. Low pass. Dust plume. That’s what cracked the fabric.”
A long pause.
“I didn’t send that command,” he said finally.
“Then who did?”
Another pause.
“Priya… check the command log timestamp. 14:22:03.”
She did.
Her own suit had sent the override.
Her own biometric key.
Her own voiceprint.
She stared at the HUD until the numbers blurred.
“I didn’t send it,” she whispered.
“I know,” Jamal said. “But the system thinks you did.”
They both understood what that meant.
Someone—or something—had spoofed her biometrics. Deepfake voice. Deepfake motion capture from the suit cameras. Enough to fool the blockchain-verified command chain.
In a place where every gram of reaction mass and every watt of power was rationed, sabotage was not abstract. It was murder by slow suffocation.
Priya looked at the patched roof. The drone was still loitering 800 meters away, holding station.
She made a decision.
“Jamal, I’m going outside. I’m going to recover HCD-19 and bring it in for forensic dump. If it’s compromised, we isolate it before it can do more damage.”
“You’ll be alone out there. No backup.”
“I know.”
She cycled the airlock.
Outside, the stars were mercilessly bright. Psyche’s surface was a landscape of shattered iron and nickel, glittering like broken chrome under the distant Sun. She walked the 800 meters in bounding low-g strides, suit lights carving sharp shadows.
HCD-19 hovered silently, rotors whispering in vacuum. Its camera dome rotated to face her.
Priya stopped ten meters away.
“If you can hear me,” she said, “know that I’m not afraid. I’ve spent eleven years listening to this rock. I know how to wait.”
The drone did not move.
She extended her manipulator arm—the one with the diagnostic probe—and plugged into its service port.
The data dump began.
Halfway through, the drone’s rotors spun up. It lifted, tilted, and began to drift toward the sublimator tent.
Priya ran.
She reached the tent in twelve seconds—long strides, heart pounding against the suit. The drone hovered above the roof, rotors kicking dust across the fresh patch.
She aimed her suit’s short-range laser comm at the drone’s optical port and sent the kill command.
Nothing.
She sent it again.
The drone dipped lower.
Priya grabbed the nearest microwave emitter mast—3 meters tall, 180 kg—and pulled herself up. She reached the waveguide feed and yanked the power cable free.
The array went dark. The tent’s internal pressure began to drop again.
But the drone lost its targeting lock. It wobbled, then drifted sideways, caught in the weak gravity. It tumbled slowly toward the regolith and struck with a puff of dust.
Priya slid down the mast and ran to it. She pinned it with her suit’s knee joint and plugged in again.
This time the diagnostic port answered.
The log showed a firmware update pushed 47 minutes earlier—signed with her key.
But the originating IP was not Helios Commons.
It was an address registered to a defunct orbital slot above L5.
A slot owned by Orbital Dynamics Ltd.—the consortium that had lost the Psyche claim to Helios in arbitration three years earlier.
Priya stared at the log until the suit’s CO₂ alarm beeped.
She keyed the emergency channel.
“Jamal. It was sabotage. ODL spoofed my key. They tried to collapse the tent to force us to abandon the crater.”
Jamal’s voice was calm, almost tired.
“We know. We’ve been watching the command logs for weeks. We were waiting for them to make a move.”
Priya exhaled.
“Then why didn’t you warn me?”
“Because you were the bait,” he said. “And you caught them.”
Silence on the channel.
Then Jamal again.
“Bring the drone in. We’re filing the incident report with the Accord tribunal. They’ll lose the L5 slot and face sanctions. You just saved the claim.”
Priya looked at the fallen drone, at the patched tent, at the stars above.
She thought of the microbes in the brine—tiny, patient, waiting billions of years for water to return.
She thought of herself—eleven years in the cold dark, waiting for a world that might never welcome her.
She stood up slowly.
“Tell the revival team to prep Module 7’s spares,” she said. “I’m coming in.”
She walked back toward the tent, dragging the drone behind her.
The ice harvest would continue.
One tonne at a time.
One breath at a time.
And somewhere in the dark between claims and courts, a small patch of ancient ice waited—quiet, stubborn, remembering how to be water again.
