Greenhouse gases

Our machine that removes carbon dioxide from the air failed last night and the carbon dioxide is now over three quarters of a percent.  On Earth the concentration of carbon dioxide is about 0.04 percent so the level here is over 18 times greater than on Earth.  Talk about greenhouse gases!  The human part of our crew breathes in oxygen and gives off carbon dioxide, just the opposite of what us plants do.  This level of carbon dioxide is toxic for the humans; it is enough to give stuffy noses and splitting headaches but for us plants, this is like being in a sweet greenhouse.  Broccoli, Sunflower, little Zuc, and I are doing all we can to breath in the carbon dioxide and exhale oxygen.  Even the algae are doing their part.  The algae filled rooter bags are full of oxygen bubbles that escape into the cabin.  I would say these stowaways have now become an essential part of the crew.  Meanwhile, Gardener is working on fixing the machine.  When disconnected from the normal cycles on Earth, plants and animals make for a complementary crew, especially when venturing into space.

Algae are doing his part to turn carbon dioxide into oxygen. All these oxygen bubbles in our rooter bag escape into the cabin. A corresponding amount of carbon dioxide has been removed.

We are working on fixing the carbon dioxide machine. A pipe connection located in this small volume has to be disconnected before we can fix the machine. Gardener says this is worse than working on his pickup truck.

Here is the pipe connection, a cantankerous fitting that in concept is easy to work with but in practice is difficult. To disconnect this requires two hands but the restricted space does not allow us to do this.

Our solution; two of us each work our right arm into the small space and with two hands we disconnect the fitting. Broccoli said this looks like sprouts planted too close together.

Behind the equipment we need headlights; this is like working in a cave.

The final fix; we disconnected the temperature sensor cable and ran a few jumper wires to fool the computer that runs the carbon dioxide machine. Now the human part of our crew can breath.
