The Martian

So far we’ve worked out it’s not the electronics, refrigeration system, instrumentation, or temperature. I’m sure it’ll turn out to be a little hole somewhere, then NASA will have 4 hours of meetings before telling me to cover it with duct tape.

Lewis and Beck opened Presupply 309. Working as best they could in their bulky EVA suits, they removed the various portions of Hab canvas and lay them on the ground. Three entire presupply probes were dedicated to the Hab.

Following a procedure they had practiced hundreds of times, they efficiently assembled the pieces. Special seal-strips between the patches ensured air-tight mating.

After erecting the main structure of the Hab, they assembled the three airlocks. Sheet AL102 had a hole perfectly sized for Airlock 1. Beck stretched the sheet tight to the seal-strips on the airlock’s exterior.

Once all airlocks were in place, Lewis flooded the Hab with air and AL102 felt pressure for the first time. They waited an hour. No pressure was lost; the setup had been perfect.

LOG ENTRY: SOL 118

My conversation with NASA about the Water Reclaimer was boring and riddled with technical details. So I’ll paraphrase it for you:

Me: “This is obviously a clog. How about I take the it apart and check the internal tubing?”

NASA: (After 5 hours of deliberation) “No. You’ll fuck it up and die.”

So I took it apart.

Yeah, I know. NASA has a lot of ultra-smart people and I should really do what they say. And I’m being too adversarial, considering they spend all day working on how to save my life.

I just get sick of being told how to wipe my ass. Independence was one of the things they looked for when choosing Ares astronauts. It’s a 13-month mission, most of it spent many light-minutes away from Earth. They wanted people who would act on their own initiative, but at the same time, obey their Commander.

If Commander Lewis were here, I’d do whatever she said, no problem. But a committee of faceless bureaucrats back on Earth? Sorry, I’m just having a tough time with it.

I was really careful. I labeled every piece as I dismantled it, and laid everything out on a table. I have the schematics in the computer, so nothing was a surprise.

And just as I’d suspected, there was a clogged tube. The Water Reclaimer was designed to purify urine and strain humidity out of the air (you exhale almost as much water as you piss). I’ve mixed my water with soil, making it mineral water. The minerals built up in the Water Reclaimer.

I cleaned out the tubing and put it all back together. It completely solved the problem. I’ll have to do it again some day, but not for 100 sols or so. No big deal.

I told NASA what I did. Our (paraphrased) conversation was:

Me: “I took it apart, found the problem, and fixed it.”

NASA: “Dick.”

AL102 shuddered in the brutal storm. Withstanding forces and pressure far greater than its design, it rippled violently against the airlock seal-strip. Other sections of canvas undulated along their seal-strips together, acting as a single sheet, but AL102 had no such luxury. The airlock barely moved, leaving AL102 to take the full force of the tempest.

The layers of plastic, constantly bending, heated the resin from pure friction. The new, more yielding environment allowed the carbon fibers to separate.

AL102 stretched.

Not much. Only 4 millimeters. But the carbon fibers, usually 500 microns apart, now had a gap eight times that width in their midst.
