Okay, Iโve had a good nightโs sleep, and things donโt seem as hopeless as they did yesterday.
Today I took stock of supplies and did a quick EVA to check up on the external equipment. Hereโs my situation:
The surface mission was supposed to be thirty-one days. For redundancy, the supply probes had enough food to last the whole crew fifty-six days. That way if one or two probes had problems, weโd still have enough food to complete the mission.
We were six days in when all hell broke loose, so that leaves enough food to feed six people for fifty days. Iโm just one guy, so itโll last me three hundred days. And thatโs if I donโt ration it. So Iโve got a fair bit of time.
Iโm pretty flush on EVA suits, too. Each crew member had two space suits: a flight spacesuit to wear during descent and ascent, and the much bulkier and more robust EVA suit to wear when doing surface operations. My flight spacesuit has a hole in it, and of course the crew was wearing the other five when they returned toย Hermes. But all six EVA suits are still here and in perfect condition.
The Hab stood up to the storm without any problems. Outside, things arenโt so rosy. I canโt find the satellite dish. It probably got blown kilometers away.
The MAV is gone, of course. My crewmates took it up toย Hermes. Though the bottom half (the landing stage) is still here. No reason to take that back up when weight is the enemy. It includes the landing gear, the fuel plant, and anything else NASA figured it wouldnโt need for the trip back up to orbit.
The MDV is on its side and thereโs a breach in the hull. Looks like the storm ripped the cowling off the reserve chute (which we didnโt have to use on landing). Once the chute was exposed, it dragged the MDV all over the place, smashing it against every rock in the area. Not that the MDV would be much use to me. Its thrusters canโt even lift its own weight. But it might have been valuable for parts. Might still be.
Both rovers are half-buried in sand, but theyโre in good shape otherwise. Their pressure seals are intact. Makes sense. Operating procedure when a storm
hits is to stop motion and wait for the storm to pass. Theyโre made to stand up to punishment. Iโll be able to dig them out with a day or so of work.
Iโve lost communication with the weather stations, placed a kilometer away from the Hab in four directions. They might be in perfect working order for all I know. The Habโs communications are so weak right now it probably canโt even reach a kilometer.
The solar cell array was covered in sand, rendering it useless (hint: solar cells need sunlight to make electricity). But once I swept the cells off, they returned to full efficiency. Whatever I end up doing, Iโll have plenty of power for it. Two hundred square meters of solar cells, with hydrogen fuel cells to store plenty of reserve. All I need to do is sweep them off every few days.
Things indoors are great, thanks to the Habโs sturdy design.
I ran a full diagnostic on the oxygenator. Twice. Itโs perfect. If anything goes wrong with it, thereโs a short-term spare I can use. But itโs solely for emergency use while repairing the main one. The spare doesnโt actually pull CO2ย apart and
recapture the oxygen. It just absorbs the CO2ย the same way the space suits do. Itโs intended to last five days before it saturates the filters, which means thirty days for me (just one person breathing, instead of six). So thereโs some
insurance there.
The water reclaimer is working fine, too. The bad news is thereโs no backup. If it stops working, Iโll be drinking reserve water while I rig up a primitive distillery to boil piss. Also, Iโll lose half a liter of water per day to breathing until the humidity in the Hab reaches its maximum and water starts condensing on every surface. Then Iโll be licking the walls. Yay. Anyway, for now, no problems with the water reclaimer.
So yeah. Food, water, shelter all taken care of. Iโm going to start rationing food right now. Meals are pretty minimal already, but I think I can eat a three-fourths portion per meal and still be all right. That should turn my three hundred days of food into four hundred. Foraging around the medical area, I found the main bottle of vitamins. Thereโs enough multivitamins there to last years. So I wonโt have any nutritional problems (though Iโll still starve to death when Iโm out of food, no matter how many vitamins I take).
The medical area has morphine for emergencies. And thereโs enough there for a lethal dose. Iโm not going to slowly starve to death, Iโll tell you that. If I get to that point, Iโll take an easier way out.
Everyone on the mission had two specialties. Iโm a botanist and mechanical engineer; basically, the missionโs fix-it man who played with plants. The mechanical engineering might save my life if something breaks.
Iโve been thinking about how to survive this. Itโs not completely hopeless. Thereโll be humans back on Mars in about four years when Ares 4 arrives (assuming they didnโt cancel the program in the wake of my โdeathโ).
Ares 4 will be landing at the Schiaparelli crater, which is about 3200 kilometers away from my location here in Acidalia Planitia. No way for me to get there on my own. But if I could communicate, I might be able to get a rescue. Not sure how theyโd manage that with the resources on hand, but NASA has a lot of smart people.
So thatโs my mission now. Find a way to communicate with Earth. If I canโt manage that, find a way to communicate withย Hermesย when it returns in four years with the Ares 4 crew.
Of course, I donโt have any plan for surviving four years on one year of food. But one thing at a time here. For now, Iโm well fed and have a purpose: Fix the damn radio.

Well, Iโve done three EVAs and havenโt found any hint of the communications dish.
I dug out one of the rovers and had a good drive around, but after days of wandering, I think itโs time to give up. The storm probably blew the dish far away and then erased any drag-marks or scuffs that might have led to a trail. Probably buried it, too.
I spent most of today out at whatโs left of the communications array. Itโs really a sorry sight. I may as well yell toward Earth for all the good that damned thing will do me.
I could throw together a rudimentary dish out of metal I find around the base, but this isnโt some walkie-talkie Iโm working with here. Communicating from Mars to Earth is a pretty big deal, and requires extremely specialized equipment. I wonโt be able to whip something up with tinfoil and gum.
I need to ration my EVAs as well as food. The CO2ย filters are not cleanable. Once theyโre saturated, theyโre done. The mission accounted for a four-hour EVA per crew member per day. Fortunately, CO2ย filters are light and small, so
NASA had the luxury of sending more than we needed. All told, I have about 1500 hoursโ worth of CO2ย filters. After that, any EVAs I do will have to be managed with bloodletting the air.
Fifteen hundred hours may sound like a lot, but Iโm faced with spending at least four years here if Iโm going to have any hope of rescue, with a minimum of several hours per week dedicated to sweeping off the solar array. Anyway.
No needless EVAs.
In other news, Iโm starting to come up with an idea for food. My botany background may come in useful after all.
Why bring a botanist to Mars? After all, itโs famous for not having anything growing there. Well, the idea was to figure out how well things grow in Martian gravity, and see what, if anything, we can do with Martian soil. The short answer is: quite a lotโฆalmost. Martian soil has the basic building blocks needed for plant growth, but thereโs a lot of stuff going on in Earth soil that Mars soil doesnโt have, even when itโs placed in an Earth atmosphere and given plenty of water. Bacterial activity, certain nutrients provided by animal life, etc. None of that is happening on Mars. One of my tasks for the mission was to see how plants grow here, in various combinations of Earth and Mars soil and atmosphere.
Thatโs why I have a small amount of Earth soil and a bunch of plant seeds with me.
I canโt get too excited, however. Itโs about the amount of soil youโd put in a window box, and the only seeds I have are a few species of grass and ferns. Theyโre the most rugged and easily grown plants on Earth, so NASA picked them as the test subjects.
So I have two problems: not enough dirt, and nothing edible to plant in it.
But Iโm a botanist, damn it. I should be able to find a way to make this happen. If I donโt, Iโll be a really hungry botanist in about a year.

I wonder how the Cubs are doing.

I got my undergrad degree at the University of Chicago. Half the people who studied botany were hippies who thought they could return to some natural world system. Somehow feeding seven billion people through pure gathering. They spent most of their time working out better ways to grow pot. I didnโt like them. Iโve always been in it for the science, not for any New World Order bullshit.
When they made compost heaps and tried to conserve every little ounce of living matter, I laughed at them. โLook at the silly hippies! Look at their pathetic attempts to simulate a complex global ecosystem in their backyard.โ
Of course, now Iโm doing exactly that. Iโm saving every scrap of biomatter I
can find. Every time I finish a meal, the leftovers go to the compost bucket. As for other biological materialโฆ
The Hab has sophisticated toilets. Shit is usually vaccum-dried, then accumulated in sealed bags to be discarded on the surface.
Not anymore!
In fact, I even did an EVA to recover the previous bags of shit from before the crew left. Being completely desiccated, this particular shit didnโt have bacteria in it anymore, but it still had complex proteins and would serve as useful manure. Adding it to water and active bacteria would quickly get it inundated, replacing any population killed by the Toilet of Doom.
I found a big container and put a bit of water in it, then added the dried shit. Since then, Iโve added my own shit to it as well. The worse it smells, the better things are going. Thatโs the bacteria at work!
Once I get some Martian soil in here, I can mix in the shit and spread it out. Then I can sprinkle the Earth soil on top. You might not think that would be an important step, but it is. There are dozens of species of bacteria living in Earth soil, and theyโre critical to plant growth. Theyโll spread out and breed likeโฆ well, like a bacterial infection.
People have been using human waste as fertilizer for centuries. Itโs even got a pleasant name: โnight soil.โ Normally, itโs not an ideal way to grow crops, because it spreads disease: Human waste has pathogens in it that, you guessed it, infect humans. But itโs not a problem for me. The only pathogens in this waste are the ones I already have.
Within a week, the Martian soil will be ready for plants to germinate in. But I wonโt plant yet. Iโll bring in more lifeless soil from outside and spread some of the live soil over it. Itโll โinfectโ the new soil and Iโll have double what I started with. After another week, Iโll double it again. And so on. Of course, all the while, Iโll be adding all new manure to the effort.
My asshole is doing as much to keep me alive as my brain.
This isnโt a new concept I just came up with. People have speculated on how to make crop soil out of Martian dirt for decades. Iโll just be putting it to the test for the first time.
I searched through the food supplies and found all sorts of things that I can plant. Peas, for instance. Plenty of beans, too. I also found several potatoes. Ifย anyย of them can still germinate after their ordeal, thatโll be great. With a nearly infinite supply of vitamins, all I need are calories of any kind to survive.
The total floor space of the Hab is about 92 square meters. I plan to dedicate all of it to this endeavor. I donโt mind walking on dirt. Itโll be a lot of work, but
Iโm going to need to cover the entire floor to a depth of 10 centimeters. That means Iโll have to transport 9.2 cubic meters of Martian soil into the Hab. I can get maybe one-tenth of a cubic meter in through the airlock at a time, and itโll be backbreaking work to collect it. But in the end, if everything goes to plan, Iโll have 92 square meters of crop-able soil.
Hell yeah Iโm a botanist! Fear my botany powers!
LOG ENTRY: SOL 15
Ugh! This is backbreaking work!
I spent twelve hours today on EVAs to bring dirt into the Hab. I only managed to cover a small corner of the base, maybe five square meters. At this rate itโll take me weeks to get all the soil in. But hey, time is one thing Iโve got.
The first few EVAs were pretty inefficient; me filling small containers and bringing them in through the airlock. Then I got wise and just put one big container in the airlock itself and filled that with small containers till it was full. That sped things up a lot because the airlock takes about ten minutes to get through.
I ache all over. And the shovels I have are made for taking samples, not heavy digging. My back is killing me. I foraged in the medical supplies and found some Vicodin. I took it about ten minutes ago. Should be kicking in soon.
Anyway, itโs nice to see progress. Time to start getting the bacteria to work on these minerals. After lunch. No three-fourths ration today. Iโve earned a full meal.

One complication I hadnโt thought of: water.
Turns out being on the surface of Mars for a few million years eliminates all the water in the soil. My masterโs degree in botany makes me pretty sure plants need wet dirt to grow in. Not to mention the bacteria that has to live in the dirt first.
Fortunately, I have water. But not as much as I want. To be viable, soil needs 40 liters of water per cubic meter. My overall plan calls for 9.2 cubic meters of soil. So Iโll eventually need 368 liters of water to feed it.
The Hab has an excellent water reclaimer. Best technology available on Earth. So NASA figured, โWhy send a lot of water up there? Just send enough for an emergency.โ Humans need three liters of water per day to be comfortable. They gave us 50 liters each, making 300 liters total in the Hab.
Iโm willing to dedicate all but an emergency 50 liters to the cause. That means I can feed 62.5 square meters at a depth of 10 centimeters. About two-thirds of the Habโs floor. Itโll have to do. Thatโs the long-term plan. For today, my goal was five square meters.
I wadded up blankets and uniforms from my departed crewmates to serve as one edge of a planter box with the curved walls of the Hab being the rest of the perimeter. It was as close to five square meters as I could manage. I filled it with sand to a depth of 10 centimeters. Then I sacrificed 20 liters of precious water to the dirt gods.
Then things got disgusting. I dumped my big container oโ shit onto the soil and nearly puked from the smell. I mixed this soil and shit together with a shovel, and spread it out evenly again. Then I sprinkled the Earth soil on top. Get to work, bacteria. Iโm counting on you. That smellโs going to stick around for a while, too. Itโs not like I can open a window. Still, you get used to it.
In other news, today is Thanksgiving. My family will be gathering in Chicago for the usual feast at my parentsโ house. My guess is it wonโt be much fun, what with me having died ten days ago. Hell, they probably just got done with my funeral.
I wonder if theyโll ever find out what really happened. Iโve been so busy staying alive I never thought of what this must be like for my parents. Right now, theyโre suffering the worst pain anyone can endure. Iโd give anything just to let them know Iโm still alive.
Iโll just have to survive to make up for it.
LOG ENTRY: SOL 22
Wow. Things really came along.
I got all the sand in and ready to go. Two-thirds of the base is now dirt. And today I executed my first dirt-doubling. Itโs been a week, and the former Martian soil is rich and lovely. Two more doublings and Iโll have covered the whole field.
All that work was great for my morale. It gave me something to do. But after things settled down a bit, and I had dinner while listening to Johanssenโs Beatles music collection, I got depressed again.
Doing the math, this wonโt keep me from starving.
My best bet for making calories is potatoes. They grow prolifically and have a reasonable caloric content (770 calories per kilogram). Iโm pretty sure the ones I have will germinate. Problem is I canโt grow enough of them. In 62 square meters, I could grow maybe 150 kilograms of potatoes in 400 days (the
time I have before running out of food). Thatโs a grand total of 115,500 calories, a sustainable average of 288 calories per day. With my height and weight, if Iโm willing to starve a little, I need 1500 calories per day.
Not even close.
So I canโt just live off the land forever. But I can extend my life. The potatoes will last me 76 days.
Potatoes grow continually, so in those 76 days, I can grow another 22,000 calories of potatoes, which will tide me over for another 15 days. After that, itโs kind of pointless to continue the trend. All told it buys me about 90 days.
So now Iโll start starving to death on Sol 490 instead of Sol 400. Itโs progress, but any hope of survival rests on me surviving until Sol 1412, when Ares 4 will land.
Thereโs about a thousand days of food I donโt have. And I donโt have a plan for how to get it.
Shit.
