THE DEPARTMENTย heads stared at the satellite image on the projection screen. โJesus,โ Mitch said. โWhat the hell happened?โ
โThe roverโs on its side,โ Mindy said, pointing to the screen. โThe trailerโs upside down. Those rectangles scattered around are solar cells.โ
Venkat put a hand on his chin. โDo we have any information on the state of the rover pressure vessel?โ
โNothing obvious,โ Mindy said.
โAny signs of Watney doing something after the accident? An EVA maybe?โ โNo EVA,โ Mindy said. โThe weatherโs clear. If heโd come out, thereโd be
visible footsteps.โ
โIs this the entire crash site?โ Bruce Ng asked.
โI think so,โ Mindy said. โUp toward the top of the photo, which is north, there are ordinary wheel tracks. Right here,โ she pointed to a large disturbance in the soil, โis where I think things went wrong. Judging by where that ditch is, Iโd say the rover rolled and slid from there. You can see the trench it left behind. The trailer flipped forward onto its roof.โ
โIโm not saying everythingโs okay,โ Bruce said, โbut I donโt think itโs as bad as it looks.โ
โGo on,โ Venkat said.
โThe roverโs designed to handle a roll,โ Bruce explained. โAnd if thereโd been pressure loss, thereโd be a starburst pattern in the sand. I donโt see anything like that.โ
โWatney may still be hurt inside,โ Mitch said. โHe could have banged his head or broken an arm or something.โ
โSure,โ Bruce said. โIโm just saying the rover is probably okay.โ โWhen was this taken?โ
Mindy checked her watch. โWe got it seventeen minutes ago. Weโll get another pic in nine minutes when MGS4โs orbit brings it into view.โ
โFirst thing heโll do is an EVA to assess damage,โ Venkat said. โMindy, keep us posted on any changes.โ

Hmm.
Yeah.
Things didnโt go well on the descent into Schiaparelli Basin. To give you some indication of how unwell they went, Iโm reaching up to the computer to type this. Because itโs still mounted near the control panel, and the rover is on its side.
I got bounced around a lot, but Iโm a well-honed machine in times of crisis. As soon as the rover toppled, I curled into a ball and cowered. Thatโs the kind of action hero I am.
It worked, too. โCause Iโm not hurt.
The pressure vessel is intact, so thatโs a plus. The valves that lead to the trailer hoses are shut. Probably means the hoses disconnected. And that means the trailer junction snapped. Wonderful.
Looking around the interior here, I donโt think anything is broken. The water tanks stayed sealed. There arenโt any visible leaks in the air tanks. The bedroom came unfolded, and itโs all over the place, but itโs just canvas, so it canโt have gotten too hurt.
The driving controls are okay, and the nav computer is telling me the rover is at an โunacceptably dangerous tilt.โ Thanks, Nav!
So I rolled. Thatโs not the end of the world. Iโm alive and the roverโs fine. Iโm more worried about the solar cells I probably rolled over. Also, since the trailer detached, thereโs a good chance itโs fucked up, too. The balloon roof it has isnโt exactly durable. If it popped, the shit inside will have been flung out in all directions and Iโll have to go find it. Thatโs my critical life support.
Speaking of life support, the rover switched over to the local tanks when the valves shut. Good boy, Rover! Hereโs a Scooby Snack.
Iโve got twenty liters of oxygen (enough to keep me breathing for forty days), but without the regulator (which is in the trailer) Iโm back to chemical CO2
absorption. I have 312 hours of filters left. Plus I have another 171 hours of EVA suit CO2ย filters as well. All told, that gives me 483 hours, which is close to twenty sols. So I have time to get things working again.
Iโm really damn close to the MAV now. About 220 kilometers. Iโm not going to let something like this stop me from getting there. And I donโt need everything to work at top form anymore. I just need the rover to work for 220 more kilometers and the life support to work for fifty-one more sols. Thatโs it.
Time to suit up and look for the trailer.

I had an EVA and things arenโt too bad. Mind you, theyโre not good.
I trashed three solar cells. Theyโre under the rover and cracked all to hell. They might still be able to piss out a few watts, but Iโm not holding out much hope. Luckily, I did come into this with one extra solar cell. I needed twenty-eight for my daily operations and I brought twenty-nine (fourteen on the roverโs roof, seven on the trailerโs roof, and eight on the makeshift shelves I installed on the sides of both vehicles).
I tried pushing the rover over, but I wasnโt strong enough. Iโll need to rig something to get a leverage advantage. Other than being on its side, I donโt see any real problems.
Well, thatโs not true. The tow hook is ruined beyond repair. Half of it ripped clean off. Fortunately, the trailer also has a tow hook, so I have a spare.
The trailerโs in a precarious situation. Itโs upside down and sitting on the inflated roof. Iโm not sure which god smiled down on me and kept that balloon from popping, but Iโm grateful. My first priority will be righting it. The longer it puts weight on that balloon, the larger the chances itโll pop.
While I was out, I collected the twenty-six solar cells that arenโt under the rover and set them up to recharge my batteries. May as well, right?
So right now, I have a few problems to tackle: First, I need to right the trailer. Or at least get the weight off the balloon. Next, I need to right the rover. Finally, I need to replace the roverโs tow hook with the one on the trailer.
Also, I should spell out a message for NASA. Theyโre probably worried.

I had a busy day today, and I got a lot done.
I started out pretty sore. I had to sleep on the wall of the rover. The bedroom wonโt work when the airlock is facing up. I did get to use the bedroom, somewhat. I folded it up and used it as a bed.
Anyway, suffice it to say, the wall of the rover wasnโt made for sleeping on.
But after a morning potato and Vicodin, I was feeling much better.
At first I figured my top priority was the trailer. Then I changed my mind. After taking a good look at it, I decided Iโd never be able to right it by myself. Iโd need the rover.
So today was focused on getting the rover righted.
I brought all my tools along on this trip, figuring Iโd need them for the MAV modifications. And along with them I brought cabling. Once I get set up at the MAV, my solar cells and batteries will be in a fixed position. I donโt want to move the rover around every time I use a drill on the far side of the MAV. So I brought all the electrical cabling I could fit.
Good thing, too. Because it doubles as rope.
I dug up my longest cable. Itโs the same one I used to power the drill that destroyedย Pathfinder. I call it my โlucky cable.โ
I plugged one end into the battery and the other into the infamous sample drill, then walked off with the drill to find solid ground. Once I found it, I kept going until Iโd gone as far as the electrical line would reach. I drove a one-meter bit half a meter into a rock, unplugged the power line, and tied it around the base of the bit.
Then I went back to the rover and tied off the cord to the roof-rack bar on the high side. Now I had a long, taut line running perpendicular to the rover.
I walked to the middle of the cord and pulled it laterally. The leverage advantage on the rover was huge. I only hoped it wouldnโt break the drill bit before it tipped the rover.
I backed away, pulling the line more and more. Something had to give, and it
wasnโt going to be me. I had Archimedes on my side. The rover finally tipped.
It fell onto its wheels, kicking up a large cloud of soft dust. It was a silent affair. I was far enough away that the thin atmosphere had no hope of carrying the sound to me.
I untied the power line, liberated the drill bit, and returned to the rover. I gave it a full systemโs check. Thatโs a boring-as-hell task, but I had to do it.
Every system and subsystem was working correctly. JPL did a damn good job making these rovers. If I get back to Earth, Iโm buying Bruce Ng a beer. Though I guess I should buy all the JPL guys a beer.
Beers for everyone if I get back to Earth.
Anyway, with the rover back on its wheels it was time to work on the trailer.
Problem is, I ran out of daylight. Remember, Iโm in a crater.
I had gotten most of the way down the Ramp when I rolled the rover. And the Ramp is up against the western edge of the crater. So the sun sets really early from my point of view. Iโm in the shadow of the western wall. And that royally sucks.
Mars is not Earth. It doesnโt have a thick atmosphere to bend light and carry particles that reflect light around corners. Itโs damn near a vacuum here. Once the sun isnโt visible, Iโm in the dark. Phobos gives me some moonlight, but not enough to work with. Deimos is a little piece of crap thatโs no good to anyone.
I hate to leave the trailer sitting on its balloon for another night, but thereโs not much else I can do. I figure itโs survived a whole day like that. Itโs probably stable for now.
And hey, with the rover righted, I get to use the bedroom again! Itโs the simple things in life that matter.

When I woke up this morning, the trailer hadnโt popped yet. So that was a good start.
The trailer was a bigger challenge than the rover. I only had to tip the rover. Iโd need to completely flip the trailer. That requires a lot more force than yesterdayโs little leverage trick.
The first step was to drive the rover to near the trailer. Then came the digging.
Oh God, the digging.
The trailer was upside down, with its nose pointed downhill. I decided the best way to right it was to take advantage of the slope and roll the trailer over its
nose. Basically to make it do a somersault to land on its wheels.
I can make this happen by tying off the cable to the rear of the trailer and towing with the rover. But if I tried that without digging a hole first, the trailer would just slide along the ground. I needed it to tip up. I needed a hole for the nose to fall into.
So I dug a hole. A hole one meter across, three meters wide, and one meter deep. It took me four miserable hours of hard labor, but I got it done.
I hopped in the rover and drove it downhill, dragging the trailer with me. As Iโd hoped, the trailer nosed into the hole and tipped up. From there, it fell onto its wheels with a huge plume of dust.
Then I sat for a moment, dumbstruck that my plan had actually worked.
And now Iโm out of daylight again. I canโt wait to get out of this damn shadow. All I need is one day of driving toward the MAV and Iโll be away from the wall. But for now itโs another early night.
Iโll spend tonight without the trailer to manage my life support. It may be righted, but I have no idea if the shit inside still works. The rover still has ample supplies for me.
Iโll spend the rest of the evening enjoying a potato. And by โenjoyingโ I mean โhating so much I want to kill people.โ
LOG ENTRY: SOL 501
I started the day with some nothinโ tea. Nothinโ tea is easy to make. First, get some hot water, then add nothinโ. I experimented with potato skin tea a few weeks ago. The less said about that the better.
I ventured into the trailer today. Not an easy task. Itโs pretty cramped in there; I had to leave my EVA suit in the airlock.
The first thing I noticed was that it was really hot inside. It took me a few minutes to work out why.
The atmospheric regulator was still in perfect working order, but it had nothing to do. Without being connected to the rover, it no longer had my CO2ย production to deal with. The atmosphere in the trailer was perfectโwhy change
anything?
With no regulation necessary, the air was not being pumped out to the AREC for freeze-separation. And thus it wasnโt coming back in as a liquid in need of heating.
But remember, the RTG gives off heat all the time. You canโt stop it. So the heat just built up. Eventually, things reached a balance point where the heat
bled through the hull as fast as the RTG could add it. If youโre curious, that balance point was a sweltering 41ยฐC.
I did a full diagnostic on the regulator and the oxygenator, and Iโm happy to report both are working perfectly.
The RTGโs water tank was empty, which is no surprise. It has an open top, not intended to be turned upside down. The floor of the trailer has a lot of puddled water that took me quite a while to sop up with my jumpsuit. I topped the tank off with some more water from a sealed container that Iโd stored in the trailer earlier. Remember, I need that water to have something for the returning air to bubble through. Thatโs my heating system.
But all things considered, it was good news. The critical components are working fine, and both vehicles are back on their wheels.
The hoses that connected the rover and trailer were designed well, and released without breaking. I simply snapped them back into place and the vehicles were sharing life support again.
The one remaining thing to fix was the tow hook. It was absolutely ruined. It took the full force of the crash. But as I suspected, the trailerโs tow hook was unscathed. So I transferred it to the rover and reconnected the two vehicles for travel.
All told, that little fender bender cost me four sols. But now Iโm back in action!
Sort of.
What if I run into another powder pit? I got lucky this time. Next time I might not get off so easy. I need a way to know if the ground in front of me is safe. At least for the duration of my time on the Ramp. Once Iโm in the Schiaparelli Basin proper, I can count on the normal sandy terrain Iโm used to.
If I could have anything, it would be a radio to ask NASA the safe path down the Ramp. Well, if I could haveย anything,ย it would be for the green-skinned yet beautiful Queen of Mars to rescue me so she can learn more about this Earth thing called โlovemaking.โ
Itโs been a long time since Iโve seen a woman. Just sayinโ.
Anyway, to ensure I donโt crash again, Iโllโ Seriouslyโฆno women in like, years. I donโt ask for much. Believe me, even back on Earth a botanist/mechanical engineer doesnโt exactly have ladies lined up at the door. But still, cโmon.
Anyway. Iโll drive slower. Likeโฆa crawl. That should give me enough time to react if one wheel starts to sink. Also, the lower speed will give me more torque, making it less likely Iโll lose traction.
Up till now Iโve been driving 25 kph, so Iโm going to cut that to 5 kph. Iโm still toward the top of the Ramp, but the whole thing is only 45 kilometers. I can take my time and get safely to the bottom in about eight hours.
Iโll do it tomorrow. Iโm already out of daylight again today. Thatโs another bonus: Once I clear the ramp, I can start beelining toward the MAV, which will take me away from the crater wall. Iโll be back to enjoying the entire dayโs sunlight instead of just half of it.
If I get back to Earth, Iโll be famous, right? A fearless astronaut who beat all the odds, right? I bet women like that.
More motivation to stay alive.

She surveyed the smiling faces in the meeting room.

Every Thanksgiving, my family used to drive from Chicago to Sandusky, an eight-hour drive. Itโs where Momโs sister lived. Dad always drove, and he was the slowest, most cautious driver who ever took the wheel.
Seriously. He drove like he was taking a driverโs test. Never exceeded the speed limit, always had his hands at ten and two, adjusted mirrors before each outing, you name it.
It was infuriating. Weโd be on the freeway, cars blowing by left and right. Some of them would blare their horns because, honestly, driving the speed limit makes you a road hazard. I wanted to get out and push.
I felt that way all damn day today. Five kph is literally a walking pace. And I drove that speed for eight hours.
But the slow speed ensured that I wouldnโt fall into any more powder pits along the way. And of course I didnโt encounter any. I could have driven full speed and had no problems. But better safe than sorry.
The good news is Iโm off the Ramp. I camped out as soon as the terrain flattened out. Iโve already overdone my driving time for the day. I could go further, I still have 15 percent battery power or so, but I want to get as much daylight on my solar cells as I can.
Iโm in the Schiaparelli Basin at last! Far from the crater wall, too. I get a full day of sunlight every day from now on.
I decided it was time for a very special occasion. I ate the meal pack labeled โSurvived Something That Should Have Killed Me.โ Oh my god, I forgot how good real food tastes.

I didnโt get as much recharge as I usually would yesterday. Because of my extended driving time, I only got up to 70 percent before night fell. So todayโs driving was abbreviated.
I got 63 kilometers before I had to camp out again. But I donโt even mind. Because Iโm only 148 kilometers from the MAV. That means Iโll get there the sol after tomorrow.

LOG ENTRY: SOL 504
Holy shit, this is awesome! Holy shit! Holy shit!
Okay calm. Calm.
I made 90 kilometers today. By my estimate, Iโm 50 kilometers from the MAV. I should get there sometime tomorrow. Iโm excited about that, but hereโs what Iโm really stoked about: I caught a blip from the MAV!
NASA has the MAV broadcasting the Ares 3 Hab homing signal. Why wouldnโt they? It makes perfect sense. The MAV is a sleek, perfectly functional machine, ready to do what itโs told. And they have it pretending to be the Ares 3 Hab, so my rover will see the signal and tell me where it is.
That is anย exceptionallyย good idea! I wonโt have to wander around looking for the thing. Iโm going straight to it.
I only caught a blip. Iโll get more as I get closer. Itโs strange to think that a sand dune will stop me from hearing what the MAV has to say when it can talk to Earth no problem. The MAV has three redundant methods of communicating with Earth, but theyโre all extremely directed and are designed for line-of-sight communication. And there arenโt any sand dunes between it and Earth when they talk.
Somehow they messed with things to make a radial signal, however weak it may be. And I heard it!
My message for the day was โGOT BEACON SIGNAL.โ If Iโd had enough rocks, I would have added, โAWESOME IDEA!!!โ But itโs a really sandy area.
โขโขโข
THE MAVย waited in southwestern Schiaparelli. It stood an impressive twenty-seven meters tall, its conical body gleaming in the midday sun.
The rover crested a nearby dune with the trailer in tow. It slowed for a few
moments, then continued toward the ship at top speed. It came to a stop twenty meters away.
There it remained for ten minutes while the astronaut inside suited up.
He stumbled excitedly out of the airlock, falling to the ground then scrambling to his feet. Beholding the MAV, he gestured to it with both arms, as if in disbelief.
He leaped into the air several times, arms held high with fists clenched. Then he knelt on one knee and fist-pumped repeatedly.
Running to the spacecraft, he hugged Landing Strut B. After a few moments, he broke off the embrace to perform another round of leaping celebrations.
Now fatigued, the astronaut stood with arms akimbo, looking up at the sleek lines of the engineering marvel before him.
Climbing the ladder on the landing stage, he reached the ascent stage and entered the airlock. He sealed the door behind him.
