Life on Mars

by Jonathan Strahan (Ed)

  But we were going far south of Hellas. I asked Sam about that. “If you’re cold all the time, why are we going all the way to the edge of the south polar cap? I mean, wouldn’t it be nicer to maybe work the Valles Marineris or someplace near the equator, where you could stay a little warmer?”

  “Cap, what’s the temperature in here, in the gig cabin?”

  “Twenty-two C,” I said, “do you feel cold?”

  “Yeah, I do, and that’s my point,” she said. I reached to adjust the temperature, and she stopped me. “What I mean is, that’s room temperature, babe, and it’s the same temperature it is in my suit, and in the fingers and toes of my suit, and everywhere. The cold isn’t outside, and it doesn’t matter whether it’s the temperature of a warm day on Earth or there’s CO2 snow falling, the cold’s in here, in me, ever since we came to Mars.”

  The drive was around 10,000 km as the road ran, but mostly it was pleasant, just making sure the gig stayed on the trail as we rolled past the huge volcanoes, the stunning view of Marineris from that hundred-mile-long bridge, and then all that ridge and peak country down south.

  Mostly Sam slept while I drove. Often I rested a hand on her neck or forehead as she dozed in the co-driver’s chair. Sometimes she shivered; I wondered if it was a long-running flu. I made her put on a mask and get extra oxygen, and that helped, but every few weeks I had to up her oxygen mix again.

  All the way down I practiced pronouncing Promethei Lingula, especially after we rounded Hellas, because Sam looked a little sicker every week, and I was so afraid she’d need help and I wouldn’t be able to make a distress call.

  Sam figured Promethei Lingula was too far for most people—they’d rather pick through Hellas’s or Argyre’s crater walls, looking for chunks of something worthwhile thrown up from deep underground in those impacts, and of course the real gamblers always wanted to work Hellas because one big Hellas Diamond was five years’ income.

  Sam already knew what it would take me fifteen marsyears to learn: she believed in making a good bet that nobody else was making. Her idea was that a shallow valley like the Promethei Lingula in the Antarctic highlands might have more stuff swept down by the glaciers, and maybe even some of the kinds of exposed veins that really old mountains had on Earth.

  As for what went wrong, well, nothing except our luck; nowadays I own three big veins down there. No, botterogator, I don’t feel like telling you a damned thing about what I own, you’re authorized to just look all that up. I don’t see that owning stuff is inspiring. I want to talk about Sam.

  We didn’t find any veins, or much of anything else, that first southern summer. And meanwhile Sam’s health deteriorated.

  By the time we were into Promethei Lingula, I was fixing most meals and doing almost all the maintenance. After the first weeks I did all the exosuit work, because her suit couldn’t seem to keep her warm, even on hundred percent oxygen. She wore gloves and extra socks even inside. She didn’t move much, but her mind was as good as ever, and with her writing the search patterns and me going out and grabbing the rocks, we could still’ve been okay.

  Except we needed to be as lucky as we’d been up in Boreas, and we just weren’t.

  Look here, botterogator, you can’t make me say luck had nothing to do with it. Luck always has a shitload to do with it. Keep this quibbling up and just see if I inspire any new Martians.

  Sometimes there’d be a whole day when there wasn’t a rock that was worth tossing in the hopper, or I’d cover a hundred km of nothing but common basalts and granites. Sam thought her poor concentration made her write bad search patterns, but it wasn’t that; it was plain bad luck.

  Autumn came, and with it some dust storms and a sun that spiraled closer to the horizon every day, so that everything was dimmer. It was time to head north; we could sell the load, such as it was, at the depot at Hellas, but by the time we got to the Bouches de Marineris, it wouldn’t cover more than a few weeks of prospecting. We might have to mortgage again; Hsieh Chi, unfortunately, was in the Vikingsburg pen for embezzling. “Maybe we could hustle someone, like we did him.”

  “Maybe I could, babe,” Sam said. “You know the business a lot better, but you’re still nobody’s sales guy, Cap. We’ve got food enough for another four months out here, and we still have credit because we’re working and we haven’t had to report our hold weight. Lots of gigs stay out for extra time—some even overwinter—and nobody can tell whether that’s because they’re way behind like us, or they’ve found a major vein and they’re exploiting it. So we can head back north, use up two months of supplies to get there, buy about a month of supplies with the cargo, go on short term credit only, and try to get lucky in one month. Or we can stay here right till we have just enough food to run for the Hellas depot, put in four months, and have four times the chance. If it don’t work Goodspeed’Il be just as lost either way.”

  “It’s going to get dark and cold,” I pointed out. “Very dark and cold. And you’re tired and cold all the time now.”

  “Dark and cold outside the cabin,” she said. Her face had the stubborn set that meant this was going to be useless. “And maybe the dark’ll make me eat more. All the perpetual daylight, maybe that’s what’s screwing my system up. We’ll try the Bouches du Marineris next time, maybe those nice regular equatorial days’ll get my internal clock working again. But for right now, let’s stay here. Sure, it’ll get darker, and the storms can get bad—”

  “Bad as in we could get buried, pierced by a rock on the wind, maybe even flipped if the wind gets in under the hull,” I pointed out. “Bad as in us and the sensors can only see what the spotlights can light. There’s a reason why prospecting is a summer job.”

  She was quiet about that for so long I thought a miracle had happened and I’d won an argument.

  Then she said, “Cap, I like it here in Goodspeed. It’s home. It’s ours. I know I’m sick, and all I can do these days is sleep, but I don’t want to go to some hospital and have you only visit on your days off from a labor crew. Goodspeed is ours and I want to live here and try to keep it.”

  So I said yes.

  For a while things got better. The first fall storms were water snow, not CO2. I watched the weather reports and we were always buttoned up tight for every storm, screens out and treads sealed against the fine dust. In those brief weeks between midnight sun and endless night, when the sun rises and sets daily in the Promethei Lingula, the thin coat of snow and frost actually made the darker rocks stand out on the surface, and there were more good ones to find too.

  Sam was cold all the time; sometimes she’d cry with just wanting to be warm. She’d eat, when I stood over her and made her, but she had no appetite. I also knew how she thought: food was the bottleneck. A fusion box supplied centuries of power to move, to compress and process the Martian air into breathability, to extract and purify water. But we couldn’t grow food, and unlike spare parts or medical care we might need now and then, we needed food every day, so food would be the thing we ran out of first. (Except maybe luck, and we were already out of that). Since she didn’t want the food anyway, she thought if she didn’t eat we could stay out and give our luck more of a chance to turn.

  The sun set for good; so far south, Phobos was below the horizon; cloud cover settled in to block the stars. It was darker than anywhere I’d ever been. We stayed.

  There was more ore in the hold but not enough more. Still no vein. We had a little luck at the mouth of one dry wash with a couple tons of ore in small chunks, but it played out in less than three weeks.

  Next place that looked at all worth trying was 140 km south, almost at the edge of the permanent cap, crazy and scary to try, but what the hell, everything about this was crazy and scary.

  The sky had cleared for the first time in weeks when we arrived. With just a little CO2 frost, it was easy to find rocks—the hot lights zapped the dry ice right off them. I found one nice big chunk of wolfenite, the size of an old trunk, right off the bat, and th
en two smaller ones; somewhere up the glacial slopes from here, there was a vein, perhaps not under permanent ice. I started the analytic program mapping slopes and finds, and went out in the suit to see if I could find and mark more rocks.

  Markeb, which I’d learned to pick out of the bunched triangles of the constellation Vela, was just about dead overhead; it’s the south pole star on Mars. It had been a while since I’d seen the stars, and I’d learned more about what I was looking at. I picked out the Coal Sack, the Southern Cross, and the Magellanic Clouds easily, though honestly, on a clear night at the Martian south pole, that’s like being able to find an elephant in a bathtub.

  I went inside; the analysis program was saying that probably the wolfenite had come from way up under the glacier, so no luck there, but also that there might be a fair amount of it lying out here in the alluvial fan, so at least we’d pick up something here. I stood up from the terminal; I’d fix dinner, then wake Sam, feed her, and tell her the semi-good news.

  When I came in with the tray, Sam was curled up, shivering and crying. I made her eat all her soup and bread, and plugged her in to breathe straight body-temperature oxygen. When she was feeling better, or at least saying she was, I took her up into the bubble to look at the stars with the lights off. She seemed to enjoy that, especially that I could point to things and show them to her, because it meant I’d been studying and learning.

  Yeah, botterogator, reinforce that learning leads to success. Sam’d like that.

  “Cap,” she said, “this is the worst it’s been, babe. I don’t think there’s anything on Mars that can fix me. I just keep getting colder and weaker. I’m so sorry—”

  “I’m starting for Hellas as soon as we get you wrapped up and have pure oxygen going into you in the bed. I’ll drive as long as I can safely, then—”

  “It won’t make any difference. You’ll never get me there, not alive,” she said. “Babe, the onboard diagnostic kit isn’t perfect but it’s good enough to show I’ve got the heart of a ninety-year-old cardiac patient. And all the indicators have gotten worse in just the last hundred hours or so. Whatever I’ve got, it’s killing me.” She reached out and stroked my tear-soaked face. “Poor Cap. Make me two promises.”

  “I’ll love you forever.”

  “I know. I don’t need you to promise that. First promise, no matter where you end up, or doing what, you learn. Study whatever you can study, acquire whatever you can acquire, feed your mind, babe. That’s the most important.”

  I nodded. I was crying pretty hard.

  “The other one is kind of weird . . . well, it’s silly.”

  “If it’s for you, I’ll do it. I promise.”

  She gasped, trying to pull in more oxygen than her lungs could hold. Her eyes were flowing too. “I’m scared to be buried out in the cold and the dark, and I can’t stand the idea of freezing solid. So . . . don’t bury me. Cremate me. I want to be warm.”

  “But you can’t cremate a person on Mars,” I protested. “There’s not enough air to support a fire, and—”

  “You promised,” she said, and died.

  I spent the next hour doing everything the first aid program said to do. When she was cold and stiff, I knew it had really happened.

  I didn’t care about Goodspeed anymore. I’d sell it at Hellas depot, buy passage to some city where I could work, start over. I didn’t want to be in our home for weeks with Sam’s body, but I didn’t have the money to call in a mission to retrieve her, and anyway they’d just do the most economical thing—bury her right here, practically at the South Pole, in the icy night.

  I curled up in my bunk and just cried for hours, then let myself fall asleep. That just made it worse; now that she was past rigor mortis she was soft to the touch, more like herself, and I couldn’t stand to store her in the cold, either, not after what I had promised. I washed her, brushed her hair, put her in a body bag, and set her in one of the dry storage compartments with the door closed; maybe I’d think of something before she started to smell.

  Driving north, I don’t think I really wanted to live, myself. I stayed up too long, ate and drank too little, just wanting the journey to be over with. I remember I drove right through at least one bad storm at peak speed, more than enough to shatter a tread on a stone or to go into a sudden crevasse or destroy myself in all kinds of ways. For days in a row, in that endless black darkness, I woke up in the driver’s chair after having fallen asleep while the deadman stopped the gig.

  I didn’t care. I wanted out of the dark.

  About the fifth day, Goodspeed’s forward left steering tread went off a drop-off of three meters or so. The gig flipped over forward to the left, crashing onto its back. Force of habit had me strapped into the seat, and wearing my suit, the two things that the manuals the insurance company said were what you had to be doing any time the gig was moving if you didn’t want to void your policy. Sam had made a big deal about that too.

  So after rolling, Goodspeed came to a stop on its back, and all the lights went out. When I finished screaming with rage and disappointment and everything else, there was still enough air (though I could feel it leaking) for me to be conscious.

  I put on my helmet and turned on the headlamp.

  I had a full capacitor charge on the suit, but Goodspeed’s fusion box had shut down. That meant seventeen hours of being alive unless I could replace it with another fusion box, but both the compartment where the two spare fusion boxes were stored, and the repair access to replace them, were on the top rear surface of the gig. I climbed outside, wincing at letting the last of the cabin air out, and poked around. The gig was resting on exactly the hatches I would have needed to open.

  Seventeen—well, sixteen, now—hours. And one big promise to keep.

  The air extractors on the gig had been running, as they always did, right up till the accident; the tanks were full of liquid oxygen. I could transfer it to my suit through the emergency valving, live for some days that way. There were enough suit rations to make it a real race between starvation and suffocation. The suit radio wasn’t going to reach anywhere that could do me any good; for long distance it depended on a relay through the gig, and the relay’s antenna was under the overturned gig.

  Sam was dead. Goodspeed was dead. And for every practical purpose, so was I.

  Neither Goodspeed nor I really needed that oxygen anymore, but Sam does, I realized. I could at least shift the tanks around, and I had the mining charges we used for breaking up big rocks.

  I carried Sam’s body into the oxygen storage, set her between two of the tanks, and hugged the body bag one more time. I don’t know if I was afraid she’d look awful, or afraid she would look alive and asleep, but I was afraid to unzip the bag.

  I set the timer on a mining charge, put that on top of her, and piled the rest of the charges on top. My little pile of bombs filled most of the space between the two oxygen tanks. Then I wrestled four more tanks to lie on the heap crosswise and stacked flammable stuff from the kitchen like flour, sugar, cornmeal, and jugs of cooking oil on top of those, to make sure the fire burned long and hot enough.

  My watch said I still had five minutes till the timer went off.

  I still don’t know why I left the gig. I’d been planning to die there, cremated with Sam, but maybe I just wanted to see if I did the job right or something—as if I could try again, perhaps, if it didn’t work? Whatever the reason, I bounded away to what seemed like a reasonable distance.

  I looked up; the stars were out. I wept so hard I feared I would miss seeing them in the blur. They were so beautiful, and it had been so long.

  Twenty kilograms of high explosive was enough energy to shatter all the LOX tanks and heat all the oxygen white hot. Organic stuff doesn’t just burn in white-hot oxygen; it explodes and vaporizes, and besides fifty kilograms of Sam, I’d loaded in a good six hundred kilograms of other organics.

  I figured all that out a long time later. In the first quarter second after the mining charge we
nt off, things were happening pretty fast. A big piece of the observation bubble—smooth enough not to cut my suit and kill me, but hard enough to send me a couple meters into the air and backward by a good thirty meters—slapped me over and sent me rolling down the back side of the ridge on which I sat, smashed up badly and unconscious, but alive.

  I think I dreamed about Sam, as I gradually came back to consciousness.

  Now, look here, botterogator, of course I’d like to be able, for the sake of the new generation of Martians, to tell you I dreamed about her giving me earnest how-to-succeed advice, and that I made a vow there in dreamland to succeed and be worthy of her and all that. But in fact it was mostly just dreams of holding her and being held, and about laughing together. Sorry if that’s not on the list.

  The day came when I woke up and realized I’d seen the medic before. Not long after that I stayed awake long enough to say “hello.” Eventually I learned that a survey satellite had picked up the exploding gig, and shot pictures because that bright light was unusual. An AI identified a shape in the dust as a human body lying outside, and dispatched an autorescue—a rocket with a people-grabbing arm. The autorescue flew out of Olympic City’s launch pad on a ballistic trajectory, landed not far from me, crept over to my not-yet-out-of-air, not-yet-frozen body, grabbed me with a mechanical arm, and stuffed me into its hold. It took off again, flew to the hospital, and handed me over to the doctor.

  Total cost of one autorescue mission, and two weeks in a human-contact hospital—which the insurance company refused to cover because I’d deliberately blown up the gig—was maybe twenty successful prospecting runs’ worth. So as soon as I could move, they indentured me and, since I was in no shape to do grunt-and-strain stuff for a while, they found a little prospector’s supply company that wanted a human manager for an office at the Hellas depot. I learned the job—it wasn’t hard—and grew with the company, eventually as Mars’s first indentured CEO.
