I’ve 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 Hab’s communications are so weak right now it probably can’t 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, I’ll 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 Hab’s sturdy design.

I ran a full diagnostic on the oxygenator. Twice. It’s perfect. If anything goes wrong with it, there’s a short-term spare I can use. But it’s solely for emergency use while repairing the main one. The spare doesn’t actually pull CO2 apart and recapture the oxygen. It just absorbs the CO2 the same way the space suits do. It’s intended to last five days before it saturates the filters, which means thirty days for me (just one person breathing, instead of six). So there’s some insurance there.

The water reclaimer is working fine, too. The bad news is there’s no backup. If it stops working, I’ll be drinking reserve water while I rig up a primitive distillery to boil piss. Also, I’ll 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 I’ll be licking the walls. Yay. Anyway, for now, no problems with the water reclaimer.

So yeah. Food, water, shelter all taken care of. I’m 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. There’s enough multivitamins there to last years. So I won’t have any nutritional problems (though I’ll still starve to death when I’m out of food, no matter how many vitamins I take).

The medical area has morphine for emergencies. And there’s enough there for a lethal dose. I’m not going to slowly starve to death, I’ll tell you that. If I get to that point, I’ll take an easier way out.

Everyone on the mission had two specialties. I’m a botanist and mechanical engineer; basically, the mission’s fix-it man who played with plants. The mechanical engineering might save my life if something breaks.

I’ve been thinking about how to survive this. It’s not completely hopeless. There’ll be humans back on Mars in about four years when Ares 4 arrives (assuming they didn’t cancel the program in the wake of my “death”).

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 they’d manage that with the resources on hand, but NASA has a lot of smart people.

So that’s my mission now. Find a way to communicate with Earth. If I can’t manage that, find a way to communicate with Hermes when it returns in four years with the Ares 4 crew.

Of course, I don’t have any plan for surviving four years on one year of food. But one thing at a time here. For now, I’m well fed and have a purpose: Fix the damn radio.

Well, I’ve done three EVAs and haven’t 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 it’s 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 what’s left of the communications array. It’s 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 isn’t some walkie-talkie I’m working with here. Communicating from Mars to Earth is a pretty big deal, and requires extremely specialized equipment. I won’t be able to whip something up with tinfoil and gum.

I need to ration my EVAs as well as food. The CO2 filters are not cleanable. Once they’re saturated, they’re done. The mission accounted for a four-hour EVA per crew member per day. Fortunately, CO2 filters are light and small, so NASA had the luxury of sending more than we needed. All told, I have about 1500 hours’ worth of CO2 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 I’m faced with spending at least four years here if I’m 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, I’m 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, it’s 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 lot… almost. Martian soil has the basic building blocks needed for plant growth, but there’s a lot of stuff going on in Earth soil that Mars soil doesn’t have, even when it’s 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.

That’s why I have a small amount of Earth soil and a bunch of plant seeds with me.

I can’t get too excited, however. It’s about the amount of soil you’d put in a window box, and the only seeds I have are a few species of grass and ferns. They’re 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 I’m a botanist, damn it. I should be able to find a way to make this happen. If I don’t, I’ll 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 didn’t like them. I’ve 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. “Look at the silly hippies! Look at their pathetic attempts to simulate a complex global ecosystem in their backyard.”

Of course, now I’m doing exactly that. I’m 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 material…

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 didn’t 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.
