[08:12] WATNEY: Test.
[08:25] JPL: Received! You gave us quite a scare there. Thanks for the โA-okayโ message. Our analysis of satellite imagery shows a complete detachment of Airlock 1. Is that correct? Whatโs your status?
[08:39] WATNEY: If by โdetachmentโ you mean โshot me out like a cannonโ then yeah. Minor cut on my forehead. Had some issues with my EVA suit (Iโll explain later). I patched up the Hab and repressurized it (main air tanks were intact). I just got power back online. The farm is dead. Iโve recovered as many potatoes as I could and stored them outside. I count 1841. That will last me 184 days. Including the remaining mission rations, Iโll start starving on Sol 584.
[08:52] JPL: Yeah, we figured. Weโre working on solutions to the food issue. Whatโs the status of the Hab systems?
[09:05] WATNEY: Primary air and water tanks were unharmed. The rover, solar array, and Pathfinder were out of the blast range. Iโll run diagnostics on the Habโs systems while I wait for your next reply. By the way, who am I talking to?
[09:18] JPL: Venkat Kapoor in Houston. Pasadena relays my messages. Iโm going to handle all direct communication with you from now on. Check the oxygenator and water reclaimer first. Theyโre the most important.
[09:31] WATNEY: Duh. Oxygenator functioning perfectly.
Water reclaimer is completely offline. Best guess is water froze up inside and burst some tubing. Iโm sure I can fix it. The Habโs main computer is also functioning without any problems. Any idea what caused the Hab to blow up?
[09:44] JPL: Best guess is fatigue on the canvas near Airlock 1. The pressurization cycle stressed it until it failed. From now on, alternate Airlock 2 and 3 for all
EVAs. Also, weโll be getting you a checklist and procedures for a full canvas exam.
[09:57] WATNEY: Yay, I get to stare at a wall for several hours! Let me know if you come up with a way for me to not starve.
[10:11] JPL: Will do.

โITโS SOLย 122,โ Bruce said. โWe have until Sol 584 to get a probe to Mars. Thatโs four hundred and sixty-two sols, which is four hundred and seventy-five days.โ
The assembled department heads of JPL furrowed their brows and rubbed
their eyes.
He stood from his chair. โThe positions of Earth and Mars arenโt ideal. The trip will take four hundred and fourteen days. Mounting the probe to the booster and dealing with inspections will take thirteen days. That leaves us with just forty-eight days to make this probe.โ
Sounds of whispered exasperation filled the room. โJesus,โ someone said.
โItโs a whole new ball game,โ Bruce continued. โOur focus is food. Anything else is a luxury. We donโt have time to make a powered-descent lander. Itโll have to be a tumbler. So we canโt put anything delicate inside. Say good-bye to all the other crap weโd planned to send.โ
โWhereโs the booster coming from?โ asked Norm Toshi, who was in charge of the reentry process.
โThe EagleEye 3 Saturn probe,โ Bruce said. โIt was scheduled to launch next month. NASA put it on hold so we can have the booster.โ
โI bet the EagleEye team was pissed about that,โ Norm said.
โIโm sure they were,โ Bruce said. โBut itโs the only booster we have thatโs big enough. Which brings me to my next point: We only get one shot at this. If we fail, Mark Watney dies.โ
He looked around the room and let that sink in.
โWe do have some things going for us,โ he finally said. โWe have some of the parts built for the Ares 4 presupply missions. We can steal from them, and thatโll save us some time. Also, weโre sending food, which is pretty robust. Even if thereโs a reentry problem and the probe impacts at high velocity, food is still food.
โAnd we donโt need a precision landing. Watney can travel hundreds of
kilometers if necessary. We just need to land close enough for him to reach it. This ends up being a standard tumble-land presupply. All we have to do is make it quickly. So letโs get to it.โ
โขโขโข
[08:02] JPL: Weโve spun up a project to get you food. Itโs been in progress for a week or so. We can get it to you before you starve, but itโll be tight. Itโll just be food and a radio. We canโt send an oxygenator, water reclaimer, or any of that other stuff without powered descent.
[08:16] WATNEY: No complaints here! You get me the food, Iโll be a happy camper. Iโve got all Hab systems up and running again. The water reclaimer is working fine now that I replaced the burst hoses. As for water supply, I have 620 liters remaining. I started with 900 liters (300 to start with, 600 more from reducing hydrazine). So I lost almost 300 liters to sublimation. Still, with the water reclaimer operational again, itโs plenty.
[08:31] JPL: Good, keep us posted on any mechanical or electronic problems. By the way, the name of the probe weโre sending is Iris. Named after the Greek goddess who traveled the heavens with the speed of wind. Sheโs also the goddess of rainbows.
[08:47] WATNEY: Gay probe coming to save me. Got it.
โขโขโข
RICH PURNELLย sipped coffee in the silent building. He ran a final test on the software heโd written. It passed. With a relieved sigh, he sank back in his chair. Checking the clock on his computer, he shook his head. 3:42 a.m.
As an astrodynamicist, Rich rarely had to work late. His job was to find the
exact orbits and course corrections needed for any given mission. Usually, it was one of the first parts of a project, all the other steps being based on the orbit.
But this time, things were reversed. Iris needed an orbital path, and nobody knew when it would launch.
Planets move as time goes by. A course calculated for a specific launch date will work only for that date. Even a single dayโs difference would result in missing Mars entirely.
So Rich had to calculateย manyย courses. He had a range of twenty-five days during which Iris might launch. He calculated one course for each.
He began an e-mail to his boss.
Mike,ย he typed,ย Attached are the courses for Iris, in 1-day increments. We should start peer review and vetting so they can be officially accepted. And you were right, I was here almost all night.
It wasnโt that bad. Nowhere near the pain of calculating orbits for Hermes. I know you get bored when I go into the math, so Iโll summarize: The small, constant thrust of Hermesโs ion drives is much harder to deal with than the large point-thrusts of presupply probes.
All 25 of the courses take 414 days, and vary only slightly in thrust duration and angle. The fuel requirement is nearly identical for the orbits and is well within the capacity of EagleEyeโs booster.
Itโs too bad. Earth and Mars are really badly positioned. Heck, itโs almost easier toโ
He stopped typing.
Furrowing his brow, he stared into the distance. โHmm,โ he said.
He grabbed his coffee cup and went to the break room for a refill.
โขโขโข
TEDDY SCANNEDย the crowded conference room. It was rare to see such an assembly of NASAโs most important people all in one place. He squared a small stack of notes heโd prepared and placed them neatly in front of him.
โI know youโre all busy,โ Teddy said. โThank you for making time for this
meeting. I need status on Project Iris from all departments. Venkat, letโs start with you.โ
โThe mission teamโs ready,โ Venkat said, looking at spreadsheets on his laptop. โThere was a minor turf war between the Ares 3 and Ares 4 presupply control teams. The Ares 3 guys said they should run it, because while Watneyโs on Mars, Ares 3 is still in progress. The Ares 4 team points out itโs their coopted probe in the first place. I ended up going with Ares 3.โ
โDid that upset Ares 4?โ Teddy asked.
โYes, but theyโll get over it. They have thirteen other presupply missions coming up. They wonโt have time to be pissy.โ
โMitch,โ Teddy said to the flight controller, โwhat about the launch?โ
Mitch pulled the earpiece from his ear. โWeโve got a control room ready,โ he said. โIโll oversee the launch, then hand cruise and landing over to Venkatโs guys.โ
โMedia?โ Teddy said, turning to Annie.
โIโm giving daily updates to the press,โ she said, leaning back in her chair. โEveryone knows Watneyโs fucked if this doesnโt work. The public hasnโt been this engaged in ship construction since Apollo 11. CNNโsย The Watney Reportย has been the number one show in its time slot for the past two weeks.โ
โThe attention is good,โ Teddy said. โItโll help get us emergency funding from Congress.โ He looked up to a man standing near the entrance. โMaurice, thanks for flying out on short notice.โ
Maurice nodded.
Teddy gestured to him and addressed the room. โFor those who donโt know him, this is Maurice Stein from Cape Canaveral. He was the scheduled pad leader for EagleEye 3, so he inherited the role for Iris. Sorry for the bait and switch, Maurice.โ
โNo problem,โ said Maurice. โGlad I can help out.โ
Teddy flipped the top page of his notes facedown beside the stack. โHowโs the booster?โ
โItโs all right for now,โ said Maurice. โBut itโs not ideal. EagleEye 3 was set to launch. Boosters arenโt designed to stand upright and bear the stress of gravity for long periods. Weโre adding external supports that weโll remove before launch. Itโs easier than disassembly. Also the fuel is corrosive to the internal tanks, so we had to drain it. In the meantime, weโre performing inspections on all systems every three days.โ
โGood, thank you,โ Teddy said. He turned his attention to Bruce Ng, who stared back at him with heavy bloodshot eyes.
โBruce, thank you for flying out, too. Howโs the weather in California these days?โ
โI wouldnโt know,โ Bruce said. โI rarely see the outdoors.โ Subdued laughter filled the room for a few seconds.
Teddy flipped another page. โTime for the big question, Bruce. Howโs Iris coming along?โ
โWeโre behind,โ Bruce said with a tired shake of his head. โWeโre going as
fast as we can, but itโs just not fast enough.โ
โI can find money for overtime,โ Teddy offered. โWeโre already working around the clock.โ
โHow far behind are we talking about?โ Teddy asked.
Bruce rubbed his eyes and sighed. โWeโve been at it twenty-nine days; so we only have nineteen left. After that, the Pad needs thirteen days to mount it on the booster. Weโre at least two weeks behind.โ
โIs that as far behind as youโre going to get?โ Teddy asked, writing a note on his papers. โOr will you slip more?โ
Bruce shrugged. โIf we donโt have any more problems, itโll be two weeks late.
But we always have problems.โ โGive me a number,โ Teddy said.
โFifteen days,โ Bruce responded. โIf we had another fifteen days, Iโm sure we could get it done in time.โ
โAll right,โ Teddy said, taking another note. โLetโs create fifteen days.โ Turning his attention to the Ares 3 flight surgeon, Teddy asked, โDr. Keller,
can we reduce Watneyโs food intake to make the rations last longer?โ
โSorry, but no,โ Keller said. โHeโs already at a minimal calorie count. In fact, considering the amount of physical labor he does, heโs eating far less than he should. And itโs only going to get worse. Soon his entire diet will be potatoes and vitamin supplements. Heโs been saving protein-rich rations for later use, but heโll still be malnourished.โ
โOnce he runs out of food, how long until he starves to death?โ Teddy asked. โPresuming an ample water supply, he might last three weeks. Shorter than a typical hunger strike, but remember heโll be malnourished and thin to begin
with.โ
Venkat raised a hand and caught their attention. โRemember, Iris is a tumbler; he might have to drive a few days to get it. And Iโm guessing itโs hard to control a rover when youโre literally starving to death.โ
โHeโs right,โ Dr. Keller confirmed. โWithin four days of running out of food, heโll barely be able to stand up, let alone control a rover. Plus, his mental faculties will rapidly decline. Heโd have a hard time even staying awake.โ
โSo the landing dateโs firm,โ Teddy said. โMaurice, can you get Iris on the booster in less than thirteen days?โ
Maurice leaned against the wall and pinched his chin. โWellโฆit only takes three days to actually mount it. The following ten are for testing and inspections.โ
โHow much can you reduce those?โ
โWith enough overtime, I could get the mounting down to two days. That includes transport from Pasadena to Cape Canaveral. But the inspections canโt be shortened. Theyโre time-based. We do checks and rechecks with set intervals between them to see if something deforms or warps. If you shorten the intervals, you invalidate the inspections.โ
โHow often do those inspections reveal a problem?โ Teddy asked. A silence fell over the room.
โUh,โ Maurice stammered. โAre you suggesting we donโt do the inspections?โ
โNo,โ said Teddy. โRight now Iโm asking how often they reveal a problem.โ โAbout one in twenty launches.โ
Teddy wrote that down. โAnd how often is the problem they find something that would have caused a mission failure?โ
โIโm, uh, not sure. Maybe half the time?โ
He wrote that down as well. โSo if we skip inspections and testing, we have a one in forty chance of mission failure?โ Teddy asked.
โThatโs two point five percent,โ Venkat said, stepping in. โNormally, thatโs grounds for a countdown halt. We canโt take a chance like that.โ
โโNormallyโ was a long time ago,โ Teddy said. โNinety-seven point five percent is better than zero. Can anyone think of a safer way to get more time?โ
He scanned the room. Blank faces stared back.
โAll right, then,โ he said, circling something on his notes. โSpeeding up the mounting process and skipping inspections buys us eleven days. If Bruce can pull a rabbit out of a hat and get done sooner, Maurice can do some inspections.โ
โWhat about the other four days?โ Venkat asked.
โIโm sure Watney can stretch the food to last four extra days, malnutrition notwithstanding,โ Teddy said, looking to Dr. Keller.
โIโโ Keller started. โI canโt recommendโโ
โHang on,โ Teddy interrupted. He stood and straightened his blazer. โEveryone, I understand your positions. We have procedures. Skipping those procedures means risk. Risk means trouble for your department. But now isnโt the time to cover our asses. We have to take risks or Mark Watney dies.โ
Turning to Keller, he said, โMake the food last another four days.โ Keller nodded.

โRICH,โย said Mike.
Rich Purnell concentrated on his computer screen. His cubicle was a landfill of printouts, charts, and reference books. Empty coffee cups rested on every surface; take-out packaging littered the ground.
โRich,โ Mike said, more forcefully. Rich looked up. โYeah?โ
โWhat the hell are you doing?โ
โJust a little side project. Something I wanted to check up on.โ
โWellโฆthatโs fine, I guess,โ Mike said, โbut you need to do your assigned work first. I asked for those satellite adjustments two weeks ago and you still havenโt done them.โ
โI need some supercomputer time,โ Rich said.
โYou need supercomputer time to calculate routine satellite adjustments?โ โNo, itโs for this other thing Iโm working on,โ Rich said.
โRich, seriously. You have to do your job.โ
Rich thought for a moment. โWould now be a good time for a vacation?โ he asked.
Mike sighed. โYou know what, Rich? I think now would be anย idealย time for you to take a vacation.โ
โGreat!โ Rich smiled. โIโll start right now.โ โSure,โ Mike said. โGo on home. Get some rest.โ
โOh, Iโm not going home,โ said Rich, returning to his calculations.
Mike rubbed his eyes. โOkay, whatever. About those satellite orbitsโฆ?โ โIโm on vacation,โ Rich said without looking up.
Mike shrugged and walked away.

[08:01] WATNEY: Howโs my care package coming along? [08:16] JPL: A little behind schedule, but weโll get it
done. In the meantime, we want you to get back to work. Weโre satisfied the Hab is in good condition. Maintenance only takes you twelve hours per week. Weโre going to pack
the rest of your time with research and experiments. [08:31] WATNEY: Great! Iโm sick of sitting on my ass.
Iโm going to be here for years. You may as well make use of me.
[08:47] JPL: Thatโs what weโre thinking. Weโll get you a schedule as soon as the science team puts it together.
Itโll be mostly EVAs, geological sampling, soil tests, and weekly self-administered medical tests. Honestly, this is the best โbonus Mars timeโ weโve had since the Opportunity lander.
[09:02] WATNEY: Opportunity never went back to Earth. [09:17] JPL: Sorry. Bad analogy.

THE JPLย Spacecraft Assembly Facility, known as the โclean room,โ was the little-known birthplace of the most famous spacecraft in Mars exploration history. Mariner, Viking, Spirit, Opportunity, and Curiosity, just to name a few, had all been born in this one room.
Today, the room was abuzz with activity as technicians sealed Iris into the
specially designed shipping container.
The off-duty techs watched the procedure from the observation deck. They had rarely seen their homes in the last two months; a makeshift bunk room had been set up in the cafeteria. Fully a third of them would normally be asleep at this hour, but they did not want to miss this moment.
The shift leader tightened the final bolt. As he retracted the wrench, the engineers broke into applause. Many of them were in tears.
After sixty-three days of grueling work, Iris was complete.
โขโขโข
ANNIE TOOKย the podium and adjusted the microphone. โThe launch preparations are complete,โ she said. โIris is ready to go. The scheduled launch is 9:14 a.m.
โOnce launched, it will stay in orbit for at least three hours. During that time,
Mission Control will gather exact telemetry in preparation for the trans-Mars injection burn. When thatโs complete, the mission will be handed off to the Ares 3 presupply team, who will monitor its progress over the following
months. It will take four hundred and fourteen days to reach Mars.โ
โAbout the payload,โ a reporter asked, โI hear thereโs more than just food?โ โThatโs true.โ Annie smiled. โWe allocated one hundred grams for luxury
items. There are some handwritten letters from Markโs family, a note from the
President, and a USB drive filled with music from all ages.โ โAny disco?โ someone asked.
โNo disco,โ Annie said, as chuckles cascaded through the room.
CNNโs Cathy Warner spoke up. โIf this launch fails, is there any recourse for Watney?โ
โThere are risks to any launch,โ Annie said, sidestepping the question, โbut we donโt anticipate problems. The weather at the Cape is clear with warm temperatures. Conditions couldnโt be better.โ
โIs there any spending limit to this rescue operation?โ another reporter asked. โSome people are beginning to ask how much is too much.โ
โItโs not about the bottom line,โ Annie said, prepared for the question. โItโs about a human life in immediate danger. But if you want to look at it financially, consider the value of Mark Watneyโs extended mission. His prolonged mission and fight for survival are giving us more knowledge about Mars than the rest of the Ares program combined.โ
โขโขโข
โDO YOUย believe in God, Venkat?โ Mitch asked. โSure, lots of โem,โ Venkat said. โIโm Hindu.โ โAsk โem all for help with this launch.โ
โWill do.โ
Mitch stepped forward to his station in Mission Control. The room bustled with activity as the dozens of controllers each made final preparations for launch.
He put his headset on and glanced at the time readout on the giant center screen at the front of the room. He turned on his headset and said, โThis is the flight director. Begin launch status check.โ
โRoger that, Houstonโ was the reply from the launch control director in Florida. โCLCDR checking all stations are manned and systems ready,โ he broadcast. โGive me a go/no-go for launch. Talker?โ
โGoโ was the response.
โTimer.โ
โGo,โ said another voice. โQAM1.โ

Resting his chin on his hands, Mitch stared at the center screen. It showed the pad video feed. The booster, amid cloudy water vapor from the cooling process, still hadย EagleEye3ย stenciled on the side.

Venkat leaned against the back wall. He was an administrator. His job was done. He could only watch and hope. His gaze was fixated on the far wallโs displays. In his mind, he saw the numbers, the shift juggling, the outright lies and borderline crimes heโd committed to put this mission together. It would all be worthwhile, if it worked.

Bruce Ng sat in the JPL cafeteria along with hundreds of engineers who had

Millions of kilometers away, the crew ofย Hermesย listened as they crowded around Johanssenโs station. The two-minute transmission time didnโt matter. They had no way to help; there was no need to interact. Johanssen stared intently at her screen, although it displayed only the audio signal strength. Beck wrung his hands. Vogel stood motionless, his eyes fixed on the floor. Martinez prayed silently at first, then saw no reason to hide it. Commander Lewis stood apart, her arms folded across her chest.

โHouston, this is Launch Control, we are go for launch.โ

โRoger that, Houston,โ Launch Control said. โLaunch on schedule.โ
Once the clock reached โ00:00:15, the television networks got what they were waiting for. The timer controller began the verbal countdown. โFifteen,โ she said, โfourteenโฆthirteenโฆtwelveโฆelevenโฆโ
Thousands had gathered at Cape Canaveral, the largest crowd ever to watch an unmanned launch. They listened to the timer controllerโs voice as it echoed across the grandstands.
โโฆtenโฆnineโฆeightโฆsevenโฆโ
Rich Purnell, entrenched in his orbital calculations, had lost track of time. He didnโt notice when his coworkers migrated to the large meeting room where a TV had been set up. In the back of his mind, he thought the office was unusually quiet, but he gave it no further thought.
โโฆsixโฆfiveโฆfourโฆโ โIgnition sequence start.โ โโฆthreeโฆtwoโฆoneโฆโ
Clamps released, the booster rose amid a plume of smoke and fire, slowly at
first, then racing ever faster. The assembled crowd cheered it on its way. โโฆand liftoff of the Iris supply probe,โ the timer controller said.
As the booster soared, Mitch had no time to watch the spectacle on the main screen. โTrim?โ he called out.
โTrimโs good, Flightโ was the immediate response. โCourse?โ he asked.
โOn course.โ
โAltitude one thousand meters,โ someone said.
โWeโve reached safe-abort,โ another person called out, indicating that the ship could crash harmlessly into the Atlantic Ocean if necessary.
โAltitude fifteen hundred meters.โ โPitch and roll maneuver commencing.โ โGetting a little shimmy, Flight.โ
Mitch looked over to the ascent flight director. โSay again?โ โA slight shimmy. Onboard guidance is handling it.โ
โKeep an eye on it,โ Mitch said. โAltitude twenty-five hundred meters.โ
โPitch and roll complete, twenty-two seconds till staging.โ
โขโขโข
WHEN DESIGNINGย Iris, JPL accounted for catastrophic landing failure. Rather than normal meal kits, most of the food was cubed protein bar material, which would still be edible even if Iris failed to deploy its tumble balloons and impacted at incredible speed.
Because Iris was an unmanned mission, there was no cap on acceleration.
The contents of the probe endured forces no human could survive. But while NASA had tested the effects of extreme g-forces on protein cubes, they had not done so with a simultaneous lateral vibration. Had they been given more time, they would have.
The harmless shimmy, caused by a minor fuel mixture imbalance, rattled the payload. Iris, mounted firmly within the aeroshell atop the booster, held firm. The protein cubes inside Iris did not.
At the microscopic level, the protein cubes were solid food particles suspended in thick vegetable oil. The food particles compressed to less than half their original size, but the oil was barely affected at all. This changed the
volume ratio of solid to liquid dramatically, which in turn made the aggregate act as a liquid. Known as โliquefaction,โ this process transformed the protein cubes from a steady solid into a flowing sludge.
Stored in a compartment that originally had no leftover space, the now-compressed sludge had room to slosh.
The shimmy also caused an imbalanced load, forcing the sludge toward the edge of its compartment. This shift in weight only aggravated the larger problem, and the shimmy grew stronger.
โขโขโข
โSHIMMYโS GETTINGย violent,โ reported the ascent flight director. โHow violent?โ Mitch said.
โMore than we like,โ he said. โBut the accelerometers caught it and calculated the new center of mass. The guidance computer is adjusting the enginesโ thrusts to counteract. Weโre still good.โ
โKeep me posted,โ Mitch said. โThirteen seconds till staging.โ
The unexpected weight shift had not spelled disaster. All systems were designed for worst-case scenarios; each did its job admirably. The ship continued toward orbit with only a minor course adjustment, implemented automatically by sophisticated software.
The first stage depleted its fuel, and the booster coasted for a fraction of a second as it jettisoned stage clamps via explosive bolts. The now-empty stage fell away from the craft as the second-stage engines prepared to ignite.
The brutal forces had disappeared. The protein sludge floated free in the container. Given two seconds, it would have re-expanded and solidified. But it was given only a quarter second.
As the second stage fired, the craft experienced a sudden jolt of immense force. No longer contending with the deadweight of the first stage, the acceleration was profound. The three hundred kilograms of sludge slammed into the back of its container. The point of impact was at the edge of Iris, nowhere near where the mass was expected to be.
Though Iris was held in place by five large bolts, the force was directed entirely to a single one. The bolt was designed to withstand immense forces; if necessary to carry the entire weight of the payload. But it wasย notย designed to sustain a sudden impact from a loose three-hundred-kilogram mass.
The bolt sheared. The burden was then shifted to the remaining four bolts. The forceful impact having passed, their work was considerably easier than that of their fallen comrade.
Had the pad crew been given time to do normal inspections, they would have noticed the minor defect in one of the bolts. A defect that slightly weakened it, though it would not cause failure on a normal mission. Still, they would have swapped it out with a perfect replacement.
The off-center load presented unequal force to the four remaining bolts, the defective one bearing the brunt of it. Soon, it failed as well. From there, the other three failed in rapid succession.
Iris slipped from its supports in the aeroshell, slamming into the hull.
โขโขโข
โWOAH!โ EXCLAIMEDย the ascent flight director. โFlight, weโre getting a large precession!โ
โWhat?โ Mitch said as alerts beeped and lights flashed across all the
consoles.
โForce on Iris is at seven gโs,โ someone said. โIntermittent signal loss,โ called another voice. โAscent, whatโs happening here?โ Mitch demanded.
โAll hell broke loose. Itโs spinning on the long axis with a seventeen-degree precession.โ
โHow bad?โ
โAt least five rpโs, and falling off course.โ โCan you get it to orbit?โ
โI canโt talk to it at all; signal failures left and right.โ โComm!โ Mitch shot to the communications director.
โWorkinโ on it, Flight,โ was the response. โThereโs a problem with the onboard system.โ
โGetting some major gโs inside, Flight.โ
โGround telemetry shows it two hundred meters low of target path.โ โWeโve lost readings on the probe, Flight.โ
โEntirely lost the probe?โ he asked.
โAffirm, Flight. Intermittent signal from the ship, but no probe.โ
โShit,โ Mitch said. โIt shook loose in the aeroshell.โ โItโs dreideling, Flight.โ
โCan it limp to orbit?โ Mitch said. โEven super-low EO? We might be able to
โโ
โLoss of signal, Flight.โ โLOS here, too.โ
โSame here.โ
Other than the alarms, the room fell silent. After a moment, Mitch said, โReestablish?โ โNo luck,โ said Comm.
โGround?โ Mitch asked.
โGCโ was the reply. โVehicle had already left visual range.โ โSatCon?โ Mitch asked.
โNo satellite acquisition of signal.โ
Mitch looked forward to the main screen. It was black now, with large white letters reading โLOS.โ
โFlight,โ a voice said over the radio, โUS destroyerย Stocktonย reports debris falling from the sky. Source matches last known location of Iris.โ
Mitch put his head in his hands. โRoger,โ he said.
Then he uttered the words every flight director hopes never to say: โGC, Flight. Lock the doors.โ
It was the signal to start post-failure procedures.
From the VIP observation room, Teddy watched the despondent Mission Control Center. He took a deep breath, then let it out. He looked forlornly at the blue folder that contained his cheerful speech praising a perfect launch. He placed it in his briefcase and extracted the red folder, with theย otherย speech in it.
โขโขโข
VENKAT STAREDย out his office windows to the space center beyond. A space center that housed mankindโs most advanced knowledge of rocketry yet had still failed to execute todayโs launch.
His mobile rang. His wife again. No doubt worried about him. He let it go to
voice mail. He just couldnโt face her. Or anyone.
A chime came from his computer. Glancing over, he saw an e-mail from JPL. A relayed message fromย Pathfinder:
[16:03] WATNEY: Howโd the launch go?
