LOG ENTRY: SOL 6
I’m pretty much fu@ked.
That’s my considered opinion.
Six days in to what should be a greatest two months of my life, and it’s turned in to a nightmare.
I don’t even know who’l read this. I guess someone wil find it eventualy. Maybe a hundred years from now.
For the record… I didn’t die on Sol 6. Certainly the rest of the crew thought I did, and I can’t blame them. Maybe there’l be a day of
national mourning for me, and my Wikipedia page wil say “Mark Watney is the only human being to have died on Mars.”
And it’l be right, probably. Cause I’l surely die here. Just not on Sol 6 when everyone thinks I did.
Let’s see… where do I begin?
The Ares program. Mankind reaching out to Mars to send people to another planet for the very first time and expand the horizons of
humanity blah, blah, blah. The Ares 1 crew did their thing and came back heroes. They got the parades and fame and love of the world.
Ares 2 did the same thing, in a different location on Mars. They got a firm handshake and a hot cup of coffee when they got home.
Ares 3. Wel. That was my mission. Wel, not mine per se. Commander Lewis was in charge. I was just one of her crew. Actualy, I
was the very lowest ranked member of the crew. I would only be “in command” of the mission if I were the only remaining person.
What do you know? I’m in command.
I wonder if this log wil be recovered before the rest of the crew die of old age? I presume they got back to Earth al right. Wel, guys, if you’re reading this: It wasn’t your fault. You did what you had to do. In your position I would have done the same thing. I don’t blame you, and I’m glad you survived.
I guess I should explain how Mars missions work, for any layman who may be reading this. We got to earth orbit the normal way,
through an ordinary ship to Hermes. Al the Ares missions use Hermes to get to and from Mars. It’s realy big and cost a lot so NASA only
Once we got to Hermes, four additional unmanned missions brought us fuel and supplies while we prepared for our trip. Once
everything was a go, we set out for Mars. But not very fast. Gone are the days of heavy chemical fuel burns and trans-Mars injection
Hermes is powered by ion engines. They throw Argon out the back of the ship realy fast to get a tiny amount of acceleration. The thing
is, it doesn’t take much reactant mass, so a little Argon (and a nuclear reactor to power things) let us accelerate constantly the whole way there. You’d be amazed at how fast you can get going with a tiny acceleration over a long time.
I could regale you with tales of how we had great fun on the trip, but I won’t. We did have fun, but I don’t feel like reliving it right now.
Suffice it to say we got to Mars 124 days later without strangling each other.
From there, we took the MDV (Mars Descent Vehicle) to the surface. The MDV is basicaly a big can with some light thrusters and
parachutes attached. Its sole purpose is to get six humans from Mars orbit to the surface without kiling any of them.
And now we come to the real trick of Mars exploration: Having al our sh@t there in advance.
A total of 14 unmanned missions deposited everything we would need for surface operations. They tried their best to land al the supply
vessels in the same general area, and did a reasonably good job. Supplies aren’t nearly so fragile as humans and can hit the ground realy hard. But they tended to bounce around a lot.
Naturaly, they didn’t send us to Mars until they’d confirmed al the supplies had made it to the surface and their containers weren’t
breached. Start to finish, including supply missions, a Mars mission takes about 3 years. In fact, there were Ares 3 supplies en route to Mars while the Ares 2 crew were on their way home.
The most important piece of the advance supplies, of course, was the MAV. The “Mars Ascent Vehicle.” That was how we would get
back to Hermes after surface operations were complete. The MAV was soft-landed (as opposed to the baloon bounce-fest the other
supplies had). Of course, it was in constant communication with Houston, and if there were any problems with it, we would pass by Mars
and go back to Earth without ever landing.
The MAV is pretty cool. Turns out, through a neat set of chemical reactions with the Martian atmosphere, for every kilogram of
hydrogen you bring to Mars, you can make 13 kilograms of fuel. It’s a slow process, though. It takes 24 months to fil the tank. That’s why they sent it long before we got here.
You can imagine how disappointed I was when I discovered the MAV was gone.
It was a ridiculous sequence of events that led to me almost dying. Then an even more ridiculous sequence that led to me surviving.
The mission is designed to handle sandstorm gusts up to 150 km/hr. So Houston got understandably nervous when we got whacked
with 175 km/hr winds. We al got in our suits and huddled in the middle of the Hab, just in case it lost pressure. But the Hab wasn’t the problem.
The MAV is a spaceship. It has a lot of delicate parts. It can put up with storms to a certain extent but it can’t just get sandblasted
forever. After an hour and a half of sustained wind, NASA gave the order to abort. Nobody wanted to stop a month-long mission after
only six days but if the MAV took any more punishment we’d al get stranded down here.
We had to go out in the storm to get from the Hab to the MAV. That was going to be risky, but what choice did we have?
Everyone made it but me.
Our main communications dish, which relayed signals from the Hab to Hermes, acted like a parachute, getting torn from its foundation
and carried with the torrent. Along the way, it crashed through the reception antenna array. Then one of those long thin antennae slammed in to me end first. It tore through my suit like a bulet through butter and I felt the worst pain of my life as it ripped open my side. I vaguely remember suddenly having the wind knocked out of me (puled out of me, realy) and my ears popping painfuly as the pressure of my suit
The last thing I remember was seeing Johanssen hopelessly reaching out toward me.
I awoke to the oxygen alarm in my suit. A steady, obnoxious beeping that eventualy roused me from a deep and profound desire to
just fu@king die.
The storm had abated; I was face down, almost totaly buried in sand. As I groggily came to, I wondered why I wasn’t more dead.
The antenna had enough force to punch through the suit and my side, but then it got stopped by my pelvis. So there was only one hole
in the suit (and a hole in me, of course).
I had been knocked back quite a ways and roled down a steep hil. Somehow I landed face down, which forced the antenna to a
strongly oblique angle that put a lot of torque on the hole in the suit. It made a weak seal.
Then, the copious blood from my wound trickled down toward the hole. As the blood reached the site of the breach, the water in it
quickly evaporated from the airflow and low pressure, leaving only a gunky residue behind. More blood came in behind it and was also
reduced to gunk. Eventualy, the blood sealed the gaps around the hole and reduced the leak to something the suit could counteract.
The suit did its job admirably. Seeing the drop in pressure, it constantly flooded itself with air from my nitrogen tank to equalize. Once the leak became manageable, it only had to trickle new air in slowly the relieve the air lost.
After a while, the CO2 (carbon dioxide) absorbers in the suit were expended. That’s realy the limiting factor to life support. Not the
amount of oxygen you bring with you, but the amount of CO2 you can remove. In the Hab, we had the Oxygenator, a large piece of
equipment that could break CO2 apart and give the oxygen back. But the spacesuits had to be portable, so they used a simple chemical
absorption process with expendable filters. I’d been asleep long enough that my filters were useless.
The suit saw this problem and moved in to an emergency mode the engineers cal “bloodletting”. Having no way to separate out the
CO2, the suit deliberately vented air to the Martian atmosphere, then back-filed with nitrogen. Between the breach and the bloodletting, it quickly ran out of nitrogen. Al it had left was my oxygen tank.
So it did the only thing it could to keep me alive. It started back-filing with pure oxygen. I now risked dying from oxygen toxicity, as the excessively high amount of oxygen threatened to burn up my nervous system, lungs, and eyes. An ironic death for someone with a leaky space suit: too much oxygen.
Every step of the way would have had beeping alarms, alerts, and warnings. But it was the high-oxygen warning that woke me.
The sheer volume of training for a space mission is astounding. I spent a week back on Earth practicing emergency space suit drils. I
knew what to do.
Carefuly reaching to the side of my helmet, I got the breach kit. It’s nothing more than a funnel with a valve at the smal end, and an
unbelievably sticky resin on the wide end. The idea is you have the valve open and stick the wide end over a hole. The air can escape
through the valve, so it doesn’t interfere with the resin making a good seal. Then you close the valve and you’ve sealed the breach.
The tricky part was getting the antenna out of the way. I puled it out as fast as I could, wincing as the sudden pressure drop dizzied me and made the wound in my side scream in agony.
I got the breach kit over the hole and sealed it. It held. The suit back-filed the missing air with yet more oxygen. Checking my arm
readouts, I saw the suit was now at 85% oxygen. For reference, Earth’s atmosphere is about 21%. I’d be ok, so long as I didn’t spend too much time like that.
I stumbled up the hil back toward the Hab. As I crested the rise, I saw something that made me very happy and something that made
me very sad: The Hab was in-tact (yay!) and the MAV was gone (boo!).
Right that moment I knew I was screwed. But I didn’t want to just die out on the surface. I limped back to the Hab and fumbled my
way in to an airlock. As soon as it equalized, I threw off my helmet.
Entering the Hab, I doffed the suit and got my first good look at the injury. It would need stitches. Fortunately, al of us had been
trained in basic medical procedures, and the Hab had excelent medical supplies. A quick shot of local anesthetic, irrigate the wound, 9
stitches and I was done. I’d be taking antibiotics for a couple of weeks, but other than that I’d be fine.
I knew it was hopeless, but I tried firing up the communication array. No signal, of course. The primary satelite dish had broken off,
remember? And it took the reception antennae with it. The Hab had secondary and tertiary communication systems, but they were both just
for talking to the MAV, which would use its much more powerful systems to relay to Hermes. Thing is, that only works if the MAV is stil
I had no way to talk to Hermes. In time, I could locate the dish out on the surface, but it would take weeks for me to rig up any repairs, and that would be too late. In an abort, Hermes would leave orbit within 24 hours. The orbital dynamics made the trip safer and shorter the earlier you left, so why wait for no reason just to make the trip take longer?
Checking out my suit, I saw the antenna had plowed through my bio-monitor computer. When on an EVA, al the crew’s suits are
networked so we can see each others status. The rest of the crew would have seen the pressure in my suit drop to nearly 0, folowed
immediately by my bio-signs going flat. Add to that I was sent tumbling down a hil with a spear through me in the middle of a sandstorm…
yeah. They thought I was dead. How could they not?
They may have even had a brief discussion about recovering my body, but regulations were clear. In the event a crewman died on
Mars, he stayed on Mars. Leaving his body behind reduced weight for the MAV on the trip back. That meant more disposable fuel and a
larger margin of error for the return thrust. No point in giving that up for sentimentality.
So that’s the situation. I’m stranded on Mars. I have no way to communicate with Hermes or Earth. Everyone thinks I’m dead. I’m in a
Hab designed to last 31 days.
If the Oxygenator breaks down, I’l suffocate. If the Water Reclaimer breaks down, I’l die of thirst. If the Hab breaches, I’l just kind
of explode. If none of those things happen, I’l eventualy run out of food and starve to death.
So yeah. I’m fu@ked.
