Wateny slept peacefully in his bunk. He shifted slightly as some pleasant dream put a smile on his face. He'd done three EVAs the previous day, all filled with labor-intensive Hab maintenance. So he slept deeper and better than he had in a long time.

Martinez was first out of his bunk. An air force man, he could match Lewis's navy schedule with ease. "Morning, Commander," he said crisply.

"Good morning, crew!" Lewis called out. "It's a brand-new day! Sol 6! Up and at 'em!"

Watney turned away, hugging a pillow to his head. "Noisy people, go away," he mumbled.

Watney added his voice to a chorus of groans.

"Come on," Lewis prodded, "no bitching. You got forty minutes more sleep than you would've on Earth."

Johanssen sat up, but made no further move toward the harsh world outside her blankets. A career software engineer, mornings were never her forte.

Vogel slowly lumbered from his bunk, checking his watch. He wordlessly pulled on his jumpsuit, smoothing out what wrinkles he could. He sighed inwardly at the grimy feeling of another day without a shower.

"Beck!" Martinez called out, shaking the mission's doctor. "Rise and shine, bud!"

"Yeah, okay," Beck said blearily.

"Not really," Martinez said.

"Bad woman take pillow," Watney groaned, unwilling to open his eyes.

"You can tell the difference?" Watney said, passing Martinez a pack.

Having rousted the troops, Lewis sat at the comm station to check overnight messages from Houston.

Watney shuffled to the ration cupboard and grabbed a breakfast at random.

"Back on Earth, I've tipped two-hundred-pound men out of their bunks. Want to see what I can do in 0.4 g?"

"No, not really," Watney said, sitting up.

"Hand me an 'eggs,' will ya," Martinez said.

"Beck, what'll you have?" Watney continued.

"Don't care," Beck said. "Give me whatever."

Pulling the pillow from Watney's hands, Lewis said, "Let's move, Watney! Uncle Sam paid a hundred thousand dollars for every second we'll be here."

"Vogel, your usual sausages?"

Johanssen fell out of her bunk, then remained on the floor.

Watney tossed a pack to him.

"Ja, please," Vogel responded.

"Seems needlessly dangerous."

"Should you really go out with a storm on the way?" Beck asked.

Beck shrugged. "Just be careful."

"I am comfortable with that," Vogel replied, taking the proffered breakfast.

"Mnrrn," Johanssen grunted.

"Mission updates from Houston," Lewis said. "Satellites show a storm coming, but we can do surface ops before it gets here. Vogel, Martinez, you'll be with me outside. Johanssen, you're stuck tracking weather reports. Watney, your soil experiments are bumped up to today. Beck, run the samples from yesterday's EVA through the spectrometer."

"Hey Sunshine," Watney called to Johanssen. "Eating breakfast today?"

The crew ate in silence. Johanssen eventually trudged to the ration cupboard and got a coffee packet. She clumsily added hot water, then sipped until wakefulness crept in.

"Pretty sure that's a no," Watney guessed.

"Coming to Mars was needlessly dangerous," Lewis said. "What's your point?"

"Houston authorized it," Lewis said.

"You know you're a stereotype, right?"

"Will do," Lewis said. "Stay within a hundred meters of the Hab," she added.

The darkness to the east undulated and flickered in the rays of the rising sun.

"The storm," Vogel said in his accented English, "it is closer than Houston reported."

"We've got time," Lewis said. "Focus on the task at hand. This EVA's all about chemical analysis. Vogel, you're the chemist, so you're in charge of what we dig up."

"Ja," Vogel said. "Please dig thirty centimeters and get soil samples. At least one hundred grams each. Very important is thirty centimeters down."

Three figures looked eastward. Their bulky EVA suits rendered them nearly identical. Only the European Union flag on Vogel's shoulder distinguished him from Lewis and Martinez, who wore the Stars and Stripes.

"Mm," Vogel said.

They split up. Greatly improved since the days of Apollo, Ares EVA suits allowed much more freedom of motion. Digging, bending over, and bagging samples were trivial tasks.

"Yes, ma'am," said Martinez.

After a time, Lewis asked, "How many samples do you need?"

"That's fine," Lewis confirmed. "I've got four so far."

"Jesus, we're gonna end up in Oz," Watney said. "What's the abort wind speed?"

"Any predictions on the storm track?" Lewis asked.

"Johanssen here." The sysop's voice came over the radio. "Houston's upgraded the storm to 'severe.' It's going to be here in fifteen minutes."

"Technically one fifty kph," Martinez said. "Any more than that and the MAV's in danger of tipping."

"Sustained winds over one hundred kph now," she said. "Gusting to one twenty-five."

"Back to base," Lewis said.

"So that's how you want to play it?" Lewis said.

"Just call 'em as I see 'em, Commander."

The hab shook in the roaring wind as the astronauts huddled in the center. All six of them now wore their flight space suits, in case they had to scramble for an emergency takeoff in the MAV. Johanssen watched her laptop while the rest watched her.

"Seven each, perhaps?"

"Five here," Martinez said. "Of course, we can't expect the navy to keep up with the air force, now can we?"

"This is the edge of it," Johanssen said, staring at her screen. "It's gonna get worse before it gets better."

The Hab canvas rippled under the brutal assault as the internal supports bent and shivered with each gust. The cacophony grew louder by the minute.

Leaving the Hab in pairs, they grouped up outside Airlock 1. The driving wind and sand battered them, but they were able to stay on their feet.

"Hey," Watney panted. "Maybe we could shore up the MAV. Make tipping less likely."

"All right," Lewis said. "Prep for abort. We'll go to the MAV and hope for the best. If the wind gets too high, we'll launch."

Pressing through the gale, they stumbled toward the MAV, with Lewis and Beck in the lead and Watney and Johanssen bringing up the rear.

"We could use cables from the solar farm as guylines." He wheezed for a few moments, then continued. "The rovers could be anchors. The trick would be getting the line around the --"

"How?" Lewis huffed.

"Visibility is almost zero," Lewis said. "If you get lost, home in on my suit's telemetry. The wind's gonna be rougher away from the Hab, so be ready."

"He's offline," Johanssen reported. "I don't know where he is!"

"I can't see anything," Johanssen said as the crew crowded around her.

"Watney!" Johanssen exclaimed.

"Shit!" Lewis exclaimed. "Johanssen, where did you last see him?"

"Watney, report," Lewis said.

Flying wreckage slammed Watney, carrying him off into the wind.

Again, she was met with silence.

"What happened?" Lewis said.

"Line up and walk west," Lewis commanded. "Small steps. He's probably prone; we don't want to step over him."

"He was right in front of me and then he was gone," she said. "He flew off due west."

"Commander," Beck said, "before we lost telemetry, his decompression alarm went off!"

"Something hit him!" Johanssen reported.

"Okay," Lewis said. "Martinez, get to the MAV and prep for launch. Everyone else, home in on Johanssen."

"Dr. Beck," Vogel said as he stumbled through the storm, "how long can a person survive decompression?"

"Watney, report," Lewis repeated.

"Less than a minute," Beck said, emotion choking his voice.

No reply.

Staying in sight of one another, they trudged through the chaos.

Martinez fell into the MAV airlock and forced it closed against the wind. Once it pressurized, he quickly doffed his suit. Having climbed the ladder to the crew compartment, he slid into the pilot's couch and booted the system.

Grabbing the emergency launch checklist with one hand, he flicked switches rapidly with the other. One by one, the systems reported flight-ready status. As they came online, he noted one in particular.

"Commander," he radioed. "The MAV's got a seven-degree tilt. It'll tip at 12.3."

"Commander," Martinez said. "Message from Houston. We're officially scrubbed. The storm's definitely gonna be too rough."

"Johanssen," Beck said, looking at his arm computer, "Watney's bio-monitor sent something before going offline. My computer just says 'Bad Packet.'"

"I have it, too," Johanssen said. "It didn't finish transmitting. Some data's missing, and there's no checksum. Gimme a sec."

"Copy that," Lewis said.

"Copy," Lewis said.

"Temperature normal?" Lewis said, a hint of hope in her voice.

"Copy," Martinez said.

"It takes a while for the --" Beck stammered. "It takes a while to cool."

The channel fell silent for some time. They continued pressing forward, shuffling through the sandstorm, hoping for a miracle.

"They sent that four and a half minutes ago," Martinez continued, "while looking at satellite data from nine minutes ago."

"Beck," Johanssen said. "I have the raw packet. It's plaintext: BP 0, PR 0, TP 36.2. That's as far as it got."

"Copy," Beck said morosely. "Blood pressure zero, pulse rate zero, temperature normal."

"Understood," Lewis said. "Continue prepping for launch."

"Commander," Martinez said. "Tilting at 10.5 degrees now, with gusts pushing it to eleven."

"Copy," Lewis said. "Are you at pilot-release?"

"Affirmative," Martinez replied. "I can launch anytime."

"If it tips, can you launch before it falls completely over?"

"Uh," Martinez said, not expecting the question. "Yes, ma'am. I'd take manual control and go full throttle. Then I'd nose up and return to preprogrammed ascent."

"What about you, Commander?" Beck asked.

"I just ordered you to," Lewis replied. "You three, get to the ship."

"I'm searching a little more. Get moving. And Martinez, if you start to tip, launch."

"Copy that," Lewis said. "Everyone home in on Martinez's suit. That'll get you to the MAV airlock. Get in and prep for launch."

They reluctantly obeyed Lewis's order and made their way toward the MAV. The punishing wind fought them every step of the way.

Unable to see the ground, Lewis shuffled forward. Remembering something, she reached to her back and got a pair of rock-drill bits. She had added the one-meter bits to her equipment that morning, anticipating geological sampling later in the day. Holding one in each hand, she dragged them along the ground as she walked.

"You really think I'll leave you behind?" Martinez said.

After twenty meters, she turned around and walked the opposite direction. Walking a straight line proved to be impossible. Not only did she lack visual references, the endless wind pushed her off course. The sheer volume of attacking sand buried her feet with each step. Grunting, she pressed on.

"Neither do I, Doctor," said Vogel, climbing the ladder, "but the commander has given us orders. Insubordination will not help."

"No way," Martinez said. "It's made to see Hermes in orbit, not the metal in a single space suit."

"I don't feel good about this," Beck said.

"Negative," Johanssen replied. "IR can't get through sand any better than visible light."

"She is grasping," Vogel said, opening the inner door. "We must get to the couches. Please hurry."

Beck, Johanssen, and Vogel squeezed into the MAV airlock. Designed for two, it could be used by three in emergencies. As it equalized, Lewis's voice came over the radio.

"What's she thinking?" Beck asked after removing his helmet. "She's a geologist. She knows IR can't get through a sandstorm."

"What about the proximity radar?" Lewis said. "Could it detect Watney's suit?"

"Johanssen," she said, "would the rover IR camera do any good?"

"Give it a try," Lewis said.

"Commander," Martinez radioed, "we're tilting 11.6 degrees. One good gust and we're tipping."

"Thirteen degrees," Johanssen called out from her couch.

"Commander," said Beck, putting on a headset as he slid into his acceleration couch, "I know you don't want to hear this, but Watn --…Mark's dead."

Martinez gave him a stern look. Turning his attention back to the radar, he radioed, "Negative contact on proximity radar."

The MAV creaked as it tilted faster and faster.

"Copy," Lewis said. "Martinez, try the radar."

"Nothing?" Lewis asked.

"Strap in!" he yelled to the crew. "We're tipping!"

"My friend just died," Beck answered. "And I don't want my commander to die, too."

"It can barely see the Hab," he replied. "The sandstorm's fucking things up. Even if it wasn't, there's not enough metal in -- Shit!"

"Roger," Martinez radioed.

He brought the radar online and waited for it to complete a self-check. Glaring at Beck, he said, "What's the matter with you?"

Buckling his restraints, Vogel said, "We are far past balance. We will not rock back."

"We can't leave her!" Beck yelled. "Let it tip, we'll fix it!"

"You can't abandon her!" Beck said. "You can't."

"Thirty-two metric tons including fuel," Martinez said, his hands flying over the controls. "If it hits the ground, it'll do structural damage to the tanks, frame, and probably the second-stage engine. We'd never be able to fix it."

"I've got one trick. If that doesn't work, I'm following her orders."

Bringing the orbital maneuvering system online, he fired a sustained burn from the nose cone array. The small thrusters fought against the lumbering mass of the slowly tilting spacecraft.

"I don't know if it'll work. We're not tipping very fast," Martinez said. "I think it's slowing down…"

"You are firing the OMS?" Vogel asked.

"Thanks for the tip," Martinez said, maintaining the burn and watching the tilt readout. "C'mon…"

"The aerodynamic caps will have automatically ejected," Vogel said. "It will be a bumpy ascent with three holes in the side of the ship."

"Still thirteen degrees," Johanssen reported.

"What's going on up there?" Lewis radioed. "You went quiet. Respond."

"It is working," Vogel said.

"Ten percent if I don't fuck anything up," Martinez said, adjusting the thrust angle.

"Twelve point eight now," Johanssen supplied.

"Or the wind died down a little," Beck postulated. "Fuel at forty-five percent."

"OMS fuel at sixty percent," Beck said. "How much do you need to dock with Hermes?"

"Stand by," Martinez replied.

"Yeah, I see that," Martinez replied. "It'll be enough."

"Commander," Beck radioed, "you need to get to the ship now."

"OMS Fuel at twenty-two percent," Beck said.

"OMS cutoff," Martinez announced, terminating the burn.

"Still tipping back," Johanssen said. "11.6…11.5…holding at 11.5."

"Almost there…," Johanssen said. "Okay we're under 12.3."

"Twelve point six," Johanssen said. "We're tipping back."

"There is danger of damage to the vents," Vogel cautioned. "The OMS was not made for prolonged thrusts."

"Twelve point nine degrees," Johanssen said.

"I know," Martinez said. "I can dock without nose vents if I have to."

"For now," Martinez said. "I don't know if maneuvering fuel will last."

"I'm sorry, Commander," Martinez said. "You need to verbally --"

Lewis closed her eyes and nodded.

"Copy," she finally replied. "On my way."

The four crewmates awaited their commander's response.

The airlock cycled. After removing her suit, Lewis made her way to the flight cabin. She wordlessly strapped into her couch, her face a frozen mask. Only Martinez dared speak.

"Agreed," Martinez radioed. "He's gone, ma'am. Watney's gone."

They lay in silence, strapped to their couches and ready for launch. Beck looked at Watney's empty couch and saw Vogel doing the same. Martinez ran a self-check on the nose cone OMS thrusters. They were no longer safe for use. He noted the malfunction in his log.

"Still at pilot-release," he said quietly. "Ready for launch."

"Launch," she said.

"Yes, ma'am," he replied, activating the sequence.

The retaining clamps ejected from the launch gantry, falling to the ground. Seconds later, preignition pyros fired, igniting the main engines, and the MAV lurched upward.

The ship slowly gained speed. As it did, wind shear blew it laterally off course. Sensing the problem, the ascent software angled the ship into the wind to counteract it.

As fuel was consumed, the ship got lighter, and the acceleration more pronounced. Rising at this exponential rate, the craft quickly reached maximum acceleration, a limit defined not by the ship's power, but by the delicate human bodies inside.

As the ship soared, the open OMS ports took their toll. The crew rocked in their couches as the craft shook violently. Martinez and the ascent software kept it trim, though it was a constant battle. The turbulence tapered off and eventually fell to nothing as the atmosphere became thinner and thinner.

The second stage pushed the ship ever higher, and into low orbit. Lasting less time than the massive first stage, and thrusting much more smoothly, it seemed almost like an afterthought.

Suddenly, all force stopped. The first stage had been completed. The crew experienced weightlessness for several seconds, then were pressed back into their couches as the next stage began. Outside, the now-empty first stage fell away, eventually to crash on some unknown area of the planet below.

Having completed his science schedule for the day, he checked his watch. Perfect timing. The data dump would be completing soon. He floated past the reactor to the Semicone-A ladder.

Normally, an incident-free launch would be cause for celebration. This one earned only silence broken by Johanssen's gentle sobbing.

Abruptly, the engine stopped, and an oppressive calm replaced the previous cacophony.

"Main engine shutdown," Martinez said. "Ascent time: eight minutes, fourteen seconds. On course for Hermes intercept."

Beck tried not to think about the painful reason he was doing zero-g plant growth experiments. He noted the size and shape of the fern leaves, took photos, and made notes.

No mere luxury, the centripetal gravity of Hermes kept them fit. Without it, they would have spent their first week on Mars barely able to walk. Zero-g exercise regimens could keep the heart and bones healthy, but none had been devised that would give them full function from Sol 1.

Four months later…

Traveling feet-first along the ladder, he soon had to grip it in earnest as the centripetal force of the rotating ship took hold. By the time he reached Semicone-A he was at 0.4 g.

"Nothing special," Beck said. "Peer reviews of a paper I wrote a few years back."

"Hermes, this is Mitch Henderson," the message began.

"You're looking cheerful, Martinez," Beck said.

"Almost," Johanssen said. "Ninety-eight percent."

Johanssen opened the message, then sat back.

"Complete," Johanssen said. "All the personal e-mails are dispatched to your laptops. Also there's a telemetry update for Vogel and a system update for me. Huh…there's a voice message addressed to the whole crew."

Because the ship was already designed for it, they used the system on the return trip as well.

Johanssen sat at her station. Lewis sat in the adjacent seat while Vogel and Martinez hovered nearby. The data dump carried e-mails and videos from home. It was the high point of the day.

She looked over her shoulder to Lewis.

Lewis shrugged. "Play it."

"My son turned three yesterday." He beamed. "Should be some pics of the party. How about you?"

"Is it here yet?" Beck asked as he entered the bridge.

"Henderson?" Martinez said, puzzled. "Talking directly to us without CAPCOM?"

"Wha --" Beck stammered.

Lewis held her hand up to signal for silence.

Vogel stood with his mouth agape as a shocked expression swept across his face.

"I have some news," Mitch's voice continued. "There's no subtle way to put this: Mark Watney's still alive."

Martinez looked to Lewis. She leaned forward and pinched her chin.

Johanssen gasped.

"I know that's a surprise," Mitch continued. "And I know you'll have a lot of questions. We're going to answer those questions. But for now I'll just give you the basics.

"He's alive and healthy. We found out two months ago and decided not to tell you; we even censored personal messages. I was strongly against all that. We're telling you now because we finally have communication with him and a viable rescue plan. It boils down to Ares 4 picking him up with a modified MDV.

"We'll get you a full write-up of what happened, but it's definitely not your fault. Mark stresses that every time it comes up. It was just bad luck. Take some time to absorb this. Your science schedules are cleared for tomorrow. Send all the questions you want and we'll answer them. Henderson out."

"I left him behind," Lewis said quietly.

"Holy shit," Beck laughed. "Holy shit! Commander! He's alive!"

Vogel nodded excitedly. "He lives."

Johanssen stared at her screen in wide-eyed disbelief.

"But," Beck began, "we all left togeth --"

"He…He's alive?" Martinez said, then smiled.

"You followed orders," Lewis interrupted. "I left him behind. In a barren, unreachable, godforsaken wasteland."

The message's end brought stunned silence to the bridge.

Beck looked to Martinez pleadingly. Martinez opened his mouth, but could find no words to say.

Lewis trudged off the bridge.

The celebrations ceased immediately as the crew saw their commander's expression.
