Harlan activated the airlock and waited for the light to cycle from red to green. His ears popped, his jaw ached, his skin felt brittle and dry. His suit was bleeding atmosphere into the vacuum, and the gauge on his wrist said he was already down to less than twelve PSI. Jets of CO2 blasted away the regolith dust, letting the negative pressure sweep it out of the chamber. He knew the sequence: the airlock wouldn’t begin pressurizing until the scrubbers said he was clean. He held his arms out away from his body and tried to mentally smooth the creases in his suit. Dust was the enemy. Once it got into the station, there was no getting it out. It moved like a living creature: choking the air filters and shorting out electrical boards. Water recycling operations were already down to eighty percent efficiency and the station’s reservoir had a murky tint to it. Harlan held his hands under the jets and watched the caked lunar dust evaporate into nothing. At ten PSI, the suit’s life-support alarm started chirping in his helmet. There was an emergency override—Joker called it the “mommy button”—that would immediately seal and pressurize the airlock, but nobody had ever used it.
Harlan focused on the com chatter coming in from the dig site.
“…at depth… extracting core sample…”
“…spinning up to two thousand RPM…”
The voices sounded indistinct and far away, as though he was trying to listen to the boarding announcements in a crowded airport lounge. It was snowing outside. He wasn’t sure if his flight had been cancelled.
“Harlan, give me a status check on your life-support systems.” Pitcairn’s voice cut through the wireless static in his helmet. She was in the Hub, monitoring the team’s EVA activities. “Mother says your heart’s doing the whacky and you know how she worries.”
Harlan glanced at his wrist-gauge: it was in the red. Pips of white light danced in front of his eyes.
“Systems nominal: everything checks out green,” Harlan answered. “Tell Mother to stop making such a fuss.” He knew the rate of decompression would slow as his suit lost pressure, but he thought about opening the safety cover on the panic button anyway. It was Henry’s Law: at seven PSI, embolisms would begin forming in veins. Tiny bubbles of nitrogen and oxygen. If the pressure dropped much below that, his blood would boil.
He closed his eyes and slipped back to that night in Minneapolis. He drank a vodka tonic at the Sky Bar. He called Sara to let her know that his flight was delayed. She sounded apathetic about the whole thing. When he called her back to tell her that it had been canceled, she sounded relieved. He bought a bottle of Smirnoff at the duty-free shop and mixed it with orange soda from the Marriott’s vending machine until he couldn’t see straight and felt like throwing up. The hotel was right across the parking lot from the Mall of America; Northwest Airlines was footing the bill.
Metal clicked against metal, a rush of air brought back the sense of ambient sound, and the airlock’s control panel flashed green. Harlan leaned against the latch and fell into Hub 1’s main operations bay.
“All systems nominal?” Pitcairn asked as she cracked Harlan out of his suit. There was an electric edge to her voice that cut through the haze.
“I might’ve picked up a micro-tear in the lining somewhere,” Harlan said. “No big deal.”
“Yeah, and how’s it gonna look in my mission log when I have to report you dead in an airlock for being stubborn?”
“I’d try to make it sound more heroic,” Harlan answered evenly. He slid out of his HUT, hooked it onto the rack, and puked on the deck plating.
Pitcairn sighed and said, “I’m not cleaning that up.”

Harlan carried the latest core samples down to the science pod. Warwick was out on the polar maria with Team 2, but Mother was keeping an eye on them. Three weeks on station and he was still getting used to the moon’s weak gravity. Each bounce down the ladder sent a jolt through his legs. His muscles were cramping up from lack of use. The flight surgeon, a Canadian named Stone, said it was the after-affects of Caisson’s syndrome and prescribed a course of extended rest and oxygen therapy before he’d clear Harlan for EVA duty. Harlan just thought he needed more time on the elliptical. There was nothing wrong with him that a good workout couldn’t cure.
Kim sneezed into a handkerchief, glanced at the core sample, and blew his nose. “What have you got?”
“Slugs from 252 mark 43.”
Kim checked the coordinates on his map and blew his nose again. “Depth?” he asked.
Harlan checked Joker’s handwritten note on the case and answered, “Two hundred and fifty-seven meters.”
“That’s an odd one,” Kim said disinterestedly. His nose was red and his eyes were bloodshot. Harlan thought he looked like a man trying to kill a cold with a hangover. “Dump it in the meat locker with the others. I’ll get to it at some point.”
There were twenty-seven core samples in the cooler tagged and ready for the geologist’s inspection. Each core had to be broken down into millimeter-thin wafers, fed through the mass spectrometer, and catalogued into the computer. They were looking for water; more specifically, they were looking for ice. Bistatic radar showed there were veins of ice hidden under the dense regolith that covered the south pole’s lunar maria. The idea was simple enough: they would mine the ice and use it to get to Mars. Its component hydrogen would fuel a vessel’s ion engine, its oxygen would sustain the crew, and the sun would provide the energy they needed to make it there and back again. The geeks at NASA said there was an abundance of ice on the moon—all the drill team had to do was dig it up—but finding it was tricky.
Clementine’s radar imaging identified packets by density but the changes in density were relative to the surrounding matter; Prospector’s neutron spectrometer mapped out hydrogen concentrations, but there was no guarantee that any of that hydrogen was bonded to oxygen. All the drill team really had to go on was a vague sense of where the ice should be and a mission critical sense of urgency to get it out of the ground.
It proved to be slow going.
“Mother, bring up Team 2 on the monitors,” Harlan said once he was back in the Hub.
“One moment,” Mother replied. She woke her monitors and brought the rover’s streaming video online.
“Fifteen degrees off relative north, range two thousand meters.”
Harlan clicked through the control screens and checked the crew’s vitals. Pitcairn’s heart rate was slightly elevated—no doubt that was due to the excitement: it was her first EVA on the lunar surface—and Joker’s blood pressure was running a little high, but otherwise the five-member crew checked out in the green.
“…holding steady at two thousand rpm…”
“…depth two-thirty-three… two-thirty-four…”
“…grind it out…”
“…slowing to one foot per minute…”
Harlan leaned back in the controller’s chair and put his feet up on the console. Team 1 would be on station in forty minutes; Team 2 was doing fine. All he needed was a cup of coffee and a copy of the Post.
“Mother, any chance you can pull up the box score from last night’s game?”
“The Astros lost five to—”
“Harlan,” Kim’s voice cracked through the Hub’s speakers, “I need you to come down here. I think I’ve found something.”
Harlan bounced out of his chair and back down to the science pod. “What have you got?”
Kim nodded towards a microscope and said, “You tell me.”
Harlan looked through the scope and adjusted the eye-piece. At first, all he could make out were dark blobs of dust suspended in a liquid. And then something wriggled from one dark blob to another.
“What the hell?”
“If this is your idea of a joke, let me tell you, I’m not laughing.”
Harlan adjusted the focus and another wriggle darted across the slide. It looked like a microscopic tadpole: a spherical head with a long streamer of a tail.
“Where did this come from?” Harlan asked.
“That slug you brought back from 252? Solid ice. I mean, it’s loaded with debris and it looks like the usual compact regolith,” Kim sneezed into his hand and wiped his hand on his coveralls. “But the mass spectrometer, the gas chromatograph, they all say the same thing: two parts hydrogen, one part oxygen.”
“Okay, jackpot,” Harlan said. “What’s with our little friend here?”
“See, here’s the thing: my knowledge of microbiology ends at the word microbe. But I’m pretty sure that’s what you’re looking at.”
Harlan looked through the scope again. He told himself he was seeing things. He was tired. His mind was playing tricks on him.
“Mother, flash an emergency action message to all team personnel: ‘Abort EVA, return to base.’”
“Message away,” Mother responded.
Kim fished a box of tissues out of the storage locker and blew his nose furiously. Harlan looked away; the last thing he needed was a cold. Kim died seven hours later.
* * * * *
Stone zipped the body bag shut and evacuated the air. The black plastic closed in around Kim until it stretched against the contours of his face. Joker handed Harlan a cup of coffee and asked, “Since when do we have body bags?”
“Those NASA geeks think of everything,” Harlan answered quietly.
Stone sealed the medical pod and snapped off his gloves. He looked tired and lines of worry etched the corners of his eyes. Harlan knew it wasn’t the dead body. He’d read Stone’s file: the man had served two combat tours in Iraq; he was no stranger to death.
“What can you tell me?” Harlan asked.
“We won’t get an official cause of death until they perform an autopsy back on Earth,” Stone answered.
“Give me the unofficial version.”
“His lungs were full of mucus.”
“Wait, you’re telling me the guy drowned? In space?”
“He asphyxiated,” Stone replied.
“He had a cold,” Harlan said. Something in his voice snapped and he heard his anger echoing off the hull.
“Like I said before: we don’t have the proper equipment to run the necessary tests. But his lungs are full of mucus; his sinuses are impacted; his eyes, ears, nose, and throat all show signs of a systemic infection. He had a cold; it killed him.”
“Great,” Harlan sighed. “That’s just great.”
“Has anyone ever died out here before?” Joker asked. “I mean, besides Challenger and Columbia. Has anyone ever actually died in space?”
Stone ignored him. The duty roster said he was supposed to be in his rack until 0400 and he headed down the connecting corridor to crew pod. Harlan envied him and turned his attention back to the mission.
“Mother, ping the beacon at 252 mark 43.”
“Beacon 252 mark 43 is active,” Mother replied. Her voice sounded soothing. Nonplussed. As though the thought of death didn’t phase her. Kim’s passing meant nothing more than an adjustment in their oxygen consumption. If the dust knocked out one of the scrubbers, the eleven-man team could now survive one-twelfth longer.
“We need to get back out there,” Harlan said. He knew the procedure by rote and his mind started assembling the necessary checklist. “We’ve got one solid core. Imaging suggests an ice-field three kilometers wide. We’ll start at 252 and work in a spiral pattern radiating outward. Soundings at every ten meters.”
“What do we do with him?” Pitcairn asked. She nodded towards the medical pod; her voice sounded froggy.
“We’ve dug enough holes on this rock,” Joker said, “I vote we drop him in one and kick some dirt over his head. One small step and he goes from being the man who discovered alien life to the first human buried on the moon. They’ll probably name a school after him: Young Li Kim Junior High or some shit like that.”
Harlan dropped down the ladder to the prep bay and slid into his HUT. Joker checked the seals on his gloves and boots. Harlan’s breath closed in around him. The speakers in his helmet amplified the sound of his own breathing.
“Give me a com check,” Harlan said.
Kowalski, Warwick, and Pitcairn sounded off; Joker flashed a thumbs-up.
“We don’t have anyone to run the mass spectrometer,” Warwick said as the airlock cycled from green to red. The air pressure dropped and the light over the outer hatch strobed yellow. “Even if we hit an iceberg, there’s no way we’ll be able to give Houston a positive confirmation.”
“The thing about ice,” Harlan said, “it melts.”
* * * * *
The lunar maria stretched away in an endless plain of soot-gray ash, broken only by the rims of eons-old impact craters, rounded down and worn smooth by the gravitational friction that held the moon in synchronous rotation around the Earth. From the south pole, the Earth looked inverted: upside down and alien. The horn of Africa and the Straits of Magellan. There were clouds over Australia. It was winter there. Harlan wondered if it was snowing. The rover’s drive motor spun the drill shaft deeper into the maria. The tachometer was pushing yellow. Something down there was biting at the bit.
“Better ease back or you’ll burn out,” Pitcairn said.
“Roger that.” The rover’s on-board computer could give him a diagnostic reading, the automated programming could tell him what to do, but he preferred to do the work himself. He could feel the drill’s vibrations through the rover’s chassis. The vacuum of space muted out the sound, but there was a whine there that didn’t belong. He throttled back and the whine faded to a dull hum.
He listened to it, listening for the familiar strains he’d felt on thirty-seven other digs. But the tenors were off-key. The altos weren’t carrying the base notes the way they should. And it sounded like the sopranos were just mouthing along silently.
“Give me a depth reading.”
“Seventy-two meters,” Pitcairn answered. Her voice sounded stuffy and Harlan could hear the congestion building in her sinuses and throat. She’d picked up Young’s cold; there was no doubt about it.
“I’m bringing her up,” Harlan said.
“Did we hit something?”
“I don’t know,” Harlan answered. “Pull the core. Let’s set a beacon and get back to the Hub.”
“Copy that,” Pitcairn said. She sounded relieved. Harlan wondered if the geeks at NASA had thought to pack them any chicken noodle soup. The nearest twenty-four hour pharmacy was 384,403 km away and the Earth was nothing more than a blue mirage that barely crested the horizon. In a few minutes, it would set. And they would be alone under the starry sky.

Stone and Hagerman both died during the night; their bodies were resting in the medical pod beside Kim’s. Pitcairn, Kowalski, and Warwick were all showing signs of infection. Harlan had quarantined them in the crew pod. He swallowed a pair of antibiotics and told himself the twinge he felt in the back of his throat was from breathing too much of the lunar dust. The atmospheric scrubbers were scheduled to be replaced in three days; the Hub’s air had a haziness to it, like a bar scene in an old black and white movie. He watched Bogart hand roll a cigarette and strike a match as though lung cancer was something other people had to worry about.
Marshall held a test tube up to the light. The centrifuge had stratified the liquid into two layers: forty milliliters of clear water sat on top of ten milliliters of gray sludge.
Joker whistled and said, “Look at that.”
“Two-hundred and forty-seven million dollars later, and we’ve got enough water to fuel a shot glass.”
“We’ll need to find a more efficient method of purification before we can begin operations on a large scale,” Marshall said, “but at least now we know it’s possible.”
Harlan nodded. They’d mapped the edges of the ice-field, and based on their imaging and core samples, they had a rough idea of its total volume. Somewhere in the back of his head he knew conversion rates: how many metric tons of ice they needed, how many liters of water, moles of hydrogen, and days of breathable oxygen. It was a numbers game.
“NASA wants us to continue excavating,” Harlan said.
“That’s a joke, right? There are barely enough of us left to keep up with housekeeping operations.”
“There’s another shuttle scheduled for lift-off in three weeks.”
Joker said something else about mission control and where they could stick their mission objectives, but Harlan wasn’t listening. He was lost in his thoughts, watching The Maltese Falcon at the drive-in with Sara. Spade was tough-jawing a pair of detectives. They’d woken him in the middle of the night. His partner had been shot dead; Spade was their prime suspect. Harlan inhaled the soft, soapy scent of Sara’s hair. Let his hand caress her cheek. She was twenty, still a sorority girl at the University of Iowa; he was twenty-three and fresh out of the Air Force Academy. They had their whole lives ahead of them and in the back seat of her father’s Chevy, it seemed like their entire lives had been compressed into a single night. That long caress under the stars. They’d made love for the first time. Harlan didn’t want the night to ever end.
“There’s a possibility we need to consider,” Marshall said. “Suppose the microbe Kim found in the ice isn’t a microbe, suppose it’s a virus.”
“Yeah,” Harlan said.
“Yeah? That’s it? That’s all you’ve got? ‘Yeah.’”
“I spent six weeks in quarantine before I came up here,” Harlan said. “Every piece of equipment, every packet of food, everything that comes aboard station gets run through the sterilizer. Mission control thinks we brought it aboard during an EVA.”
Joker grimaced as though he’d been stomach punched. He ran his fingers through his sandy blonde hair and glanced out the porthole. The lunar maria stretched away like a smooth black sea. They were becalmed.
“What are we supposed to do?”
“Follow procedure. Quarantine those infected. Dose ourselves with antibiotics and soldier on as best we can.”
“How… how is it this has never happened before? I mean, Armstrong, Aldrin—all those Apollo guys—it’s not like we’re the first team to Moon.”
“It’s the maria,” Harlan explained quietly. “The conditions that make it ideal for ice formation… the lack of direct sunlight, limited radiation exposure… the working theory at mission control is that a virus could survive out there.”
“And our survivability? Do they have a working theory on that?”
Harlan didn’t answer. He didn’t bother. They all knew the reason NASA sent men to the moon: they were cheaper than robots and more easily replaced. It wasn’t something that needed to be said. Not out loud.
* * * * *
Harlan twisted the barrel of the atmospheric scrubber and slid it out of its housing. Soot and grime had collected on the bottom half of the cylinder. He wiped it clean with a wet rag. In principle he understood how the scrubbers worked: a lithium ion cell overcharged the molecular bonds between the carbon and oxygen, the carbon atoms remained trapped inside the ceramic lattice while the smaller pairs of oxygen leaked out as breathable O2. The ion cell still had seventeen days of life in it; Harlan decided to replace it anyway.
“Suppose we vent the whole station—blow our atmosphere and everything straight into the vacuum,” Joker suggested mildly. He was working on the other side of the Hub, pulling the charcoal filters from the main ventilation duct.
“Our little friend’s proven that it can survive hard vacuum,” Harlan answered. “Besides, we don’t have enough reserve air to re-pressurize, and even if we did, there’s no way of knowing whether our reserves have been contaminated.”
“It’s worth a shot, though, right?”
Warwick and Kowalski were dead. Marshall had lapsed into some sort of coma. Pitcairn was hanging on, but she was so weak she could barely suck fluids through a straw. Joker had tried to fix her up with an IV, but after failing to hit a vein five times in a row, they’d given up on the idea.
“And what happens to us when you blow the atmosphere?” Harlan asked. He stripped the bubble wrap off a fresh ion cell and locked it into the scrubber. The meter adjusted and showed a full stripe of green. It had enough juice to keep them pink for thirty days.
“That’s the beauty of it: we hide out in the EVA suits,” Joker said. “They’ve got their own atmospherics. We could last eight, ten hours. I figure that’s plenty of time to re-pressurize the Hub. We could hold out here until re-supply brings us some fresh tanks.”
Harlan loaded the scrubber back into its housing and screwed down the cover plate. There were four scrubbers in the Hubs. Two in each of the pods. He decided to change out the power packs on all of them. It wasn’t necessary, but it gave him something to do.
“So what do you say?” Joker asked.
“There isn’t gonna be any re-supply.”
Joker lifted the screen out of the air filter; it was choked with lunar dust. He scraped it off with a putty knife, letting chunks of impacted regolith collect in a plastic waste bag. They’d shoot it out of the airlock later.
For a while, he didn’t say anything. He just focused on his work. Once he’d scraped off the caked on layers of dust, he suctioned off the screen with a vacuum hose.
“What happens to us then?” Joker finally asked.
“The ice-field’s marked,” Harlan said. “Houston says mission accomplished.”
“Let’s pop some champagne.”
They filled the hours with the menial housekeeping chores necessary to keep the station operational, but the day passed slowly. Finally, Joker settled into the rover’s pilot seat and thumbed through a worn-out copy of Playboy; Harlan tuned the station’s antennas to ESPN’s Game of the Week. The Yankees were in Detroit, playing the second of three against the Tigers. He wasn’t a fan of either team in particular, but the nonstop patter from the announcers made it easy to forget the eight-and-a-half minute lag that separated him from the signal’s transmission.
The Tigers were down three going into the bottom of the seventh, with the core of their batting order due up, when the signal cut out and the screen filled with static.
“Mother,” Harlan said.
“Do you mind? I was watching that.”
“We are unable to establish a signal lock,” Mother replied evenly. The station’s artificial intelligence sounded not the least bit bothered by the loss.
“Ping Leonardo,” Harlan said.
“We’ve lost transmission from Earth.”
“Leonardo is not responding to ping,” Mother answered. “However, there is no cause for alarm. We have experienced previous signal interruptions. Mission control should have the problem corrected momentarily.”
Harlan waited for the game to come back on but it never did. Leonardo was their lifeline to Earth. NASA used it as a relay to maintain a constant uplink with the station at the south pole. Without it, they only had a four-hour uplink window—while the Earth was above their relative horizon—when they could send and receive signals.
“They’ve cut us off?”
“Looks that way,” Harlan replied.
“So much for the geeks at the CDC coming up with a cure.”
“I am sorry to interrupt,” Mother said, “but crewmember Marshall no longer displays any cardiac activity.”
Harlan tried to rub the exhaustion from his face but it wouldn’t go away. He wanted to close his eyes and sleep until it was over. But he was in command; there was still work to do.
“The scuttlebutt is they’re putting together another expedition,” Harlan said. “They’ll drop a new Hub somewhere well north of the maria and used a nuclear-powered excavator to harvest the ice. It’ll melt the ice to steam and collect it in a condenser. The new thinking says the reactor’s radiation should be able to kill off any viruses or microbes trapped in the ice.”
“Wish they’d thought of that six years ago,” Joker sighed.
“Yeah,” Harlan said.
He didn’t bother with a body bag; he wasn’t sure they had any left. He just carried Marshall’s corpse to the airlock and let the system cycle from green to red. A rush of air swept the body out onto the maria.
“You know the first men Spain sent to the New World? They weren’t explorers; they were conquistadors—literally, Spanish for ‘conquerors’—and they kicked the shit of the Aztecs because that’s what they were good at.
“Magellan, Scott, Raleigh: they were pirates.”
“I’m with you on Raleigh and Scott, but Magellan…”
“The Lapu-Lapu killed him in the Philippines and it wasn’t because he was preaching the Gospel. Exploring a new world’s supposed to be dangerous—men die, I get that—but not like this. Not because we caught a cold and nobody thought to pack any NyQuil.”
Harlan put a pot of coffee on and waited for it to brew. Pitcairn had rallied somewhat. She’d asked when the bunnies were going out for pickles. He had no idea what she was trying to say, but he took it as a good sign.
“I tried calling my ex-wife,” Harlan said. “I got her voicemail.”
“You were married?”
“It didn’t stick.”
Harlan poured himself a cup of coffee. He still wasn’t used to the taste of instant and he couldn’t understand why the geeks at NASA hadn’t thought to install a proper Mr. Coffee. The microgravity might’ve posed a challenge, but they’d come up with pens that could write upside-down. The old joke came back to him: the Russians called them pencils.
“We can hold out, what? A month without re-supply?”
“Thirty days,” Harlan answered.
“Thirty days. And then what?”
“They name high schools after us.”
