NASA trasha. (And recycla.)

The ATV-2: The astronauts filled it with trash, and then burned it. But, to be fair, they probably ate that trash several times before they finally tossed it.

I am adding a’s to the end of words to make them sound a little like “NASA.” Try it. It’s funa.

Anywaya, I thought I’d run a little idea I had by y’all.

I got trash. Who doesn’t? You use stuff, you make trash, and it just piles up. Under your couch, in the freezer, on top of the cat … what are you supposed to do with it? Put it on the curb? I guess, but what’s exciting and easy about that? So, my idea—which I got from the world’s various space agencies—is to take my trasha up to the roofa of my apartment building (three stories!!) and just drop it. If I’m at all accurate in my understanding of acceleration and atmospheric friction, all those Sears catalogues, plastic cups, and mouse skeletons should burn up before they hit the ground.

I mean, it’s what NASA, the European Space Agency and all of their ilk do, and it seems to work for them. Take the ESA’s recently launched ATV-3 (Automated Transfer Vehicle-3). The large, unmanned space capsule will deliver about 7 tons of cargo to the International Space Station (a few hundred pounds of food, water and oxygen, and about 6.5 tons of candy), stay docked for 4 to 6 month while the astronauts use it like a missing roommate’s walk-in closet, and then, once it’s completely full of trash, it will detach, fall towards Earth, and incinerate in the atmosphere. Easy peasy. Easya peasya.

Despite it being what I think is an elegant solutiona to waste accumulationa, there are plenty of folks out there, who may or may not be smarter than hundreds of NASA systems engineers, that believe this proves that astronauts are the worst recyclers ever. To this, I have three things to say:

1) You’re no fun.
2) Think about the fuel it takes to get those tons of junk into space. You’re worried about the waste that happens after that?
3) Wrong! In a lot of respects, astronauts on the ISS are the best recyclers in the histories of re and cycling.

See, here’s the thing about #3: astronauts may dump their candy wrappers, dead pets, banana peels and old undies (JK, they wear those undies for months) into a fiery and unforgiving atmosphere, but there’s a lot of stuff that they re-use again and again that you’d never even think of. Air, for one. And water.

When you’re breathing, farting, sweating and peeing for months on end in an airtight box floating in space, and a fresh glass of water costs between $10,000 and $15,000 for delivery, you have to be clever.

And the engineers of the ISS are clever! Consider the Environmental Control and Life Support System. Astronauts, like most of us, breath out poisonous carbon dioxide, fart out poisonous methane and sweat out poisonous ammonia. ECLSS filters out all of that to produce fresh air again. The system also splits water molecules apart to create breathable oxygen, and reclaims moisture from urine and other waist to produce more water for drinking (or ultimately breathing). I don’t know about you, but I rarely save my farts, sweat, breath and urine, much less reuse them.

All things considered, I think the ISS has a pretty sweet setup figured out. A two hundred and fifty mile trash drop-n-burn (awesome), and a system that can recycle pretty much anything that comes out of your body (also awesome). The rest of us should be so luckya.
