The Martian

Chapter 2

LOG ENTRY: SOL 7

Ok, I've had a good night's sleep, and things don't 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. Here's my situation:

The surface mission was supposed to be 31 days. For redundancy, the supply probes had enough food to last the whole crew 56 days. That way if one or two probes had problems, we'd 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 50 days. I'm just one guy, so it'll last me 300 days. And that's if I don't ration it. So I've got a fair bit of time.

The Hab stood up to the storm without any problems. Outside, things aren't so rosy. I can't find the satellite dish; it probably got blown kilometers away.

The MAV is gone, of course. My crewmates took it up to Hermes. Though the bottom half (the landing stage) is still there. 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 wouldn't need for the trip back up to orbit.

The MDV is on its side and there's a breach in the hull. Looks like the storm ripped the cowling off the reserve chute (which we didn't 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 can't even lift its own weight. But it might have been valuable for parts. Might still be.

Both rovers are half-buried in sand, but they're in good shape otherwise. Their pressure seals are in-tact. Makes sense. Operating procedure if a storm hits is to stop motion and wait for the storm to pass. They're made to stand up to punishment. I'll be able to dig them out with a day or so of work.

I've lost communication with the weather stations, placed a kilometer away from the Hab in 4 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 it in sand, rendering it useless (hint: solar cells need sunlight to make electricity). But once I swept them off, they returned to full efficiency. Whatever I end up doing, I'll have plenty of power for it. 200 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 is 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 spacesuits do. It's intended to last 5 days before it saturates the filters, which means 30 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.
