99% Alien

Roman Mars:
This is 99% Invisible. I’m Roman Mars.

“Launch Control, this is Space Venture. Radio is on.”
“Roger.”

Roman Mars:
Spacecraft design is a study in humanity. At least that’s what Mary Roach says.

Mary Roach:
My name is Mary Roach. I’m the author of “Packing For Mars: The Curious Science of Life in the Void.”

Roman Mars:
In the beginning, the designers of the space habitation modules-

Mary Roach:
The box where the crew lives.

Roman Mars:
(Yep. That’s the one.)
They stuck with what they knew.

Mary Roach:
Very few people had spent any time up there in zero gravity. People just intuitively designed it like a room on earth. There would be control panels and then there were little chairs, there were seats that you would sit on. It makes no sense. In zero gravity, you can’t sit. You would have to strap yourself to the seat.

Roman Mars:
The reason is simple.

Mary Roach:
We are humans. When we have a room, we have a floor and a ceiling, we have chairs and tables and that’s what we do. And that’s how it was designed.

Roman Mars:
But getting stuff into space is expensive. So there’s always a grand effort to minimize weight and to create the most efficient space possible. And all those human comforts came under scrutiny.

Mary Roach:
So then they went to the other extreme: get rid of it all because, in space, the walls become your table. If you have a table and you put something down on the table, the table doesn’t act like a table. It doesn’t hold it there. It just floats off. A drawer isn’t very good. You open the drawer and everything flies out. So what you have is pieces of elastic on the wall, like, you know, you pull the elastic back and you stick your clipboard in there. And everything has bits of velcro so the walls become the tables. You have a very bare box that you’re living in.

Roman Mars:
So that became the game plan. No furniture, no ceiling, no floor. A perfect utilitarian box, where the astronaut floats freely and uses every surface to the fullest.

Mary Roach:
The great thing about zero gravity: we could use the ceiling, we can put the bathroom on the wall.

Roman Mars:
But this is where the human factor comes in. The capsule became overdesigned for the zero-G condition. And it became too alien. The humanity was lost.

Mary Roach:
The one thing that the crews decided that they were not ok with was getting rid of a kitchen table, like a dining table. A place to gather around at the end of the day. You know, sit down or pretend to sit down, and talk about what you did over the day, eat. I mean we’re humans! Human beings want to sit around the table and gossip and talk about stuff and eat and drink. And the table came back. It’s a small table and there are little pieces of elastic and velcro and they all hover around the table.

Roman Mars:
So despite that horrifying scene in alien, a table on a spacecraft makes for a happy astronaut.

Roman Mars:
So in the living quarters, there’s now an effort to use earth orientation.

Mary Roach:
The bottom part is the floor, the ceiling above, walls are walls. The way that they cue them in is that the lighting will be up above. So there’s always ways so that you know what the accepted orientation is.

Roman Mars:
Keeping one orientation helps in the constant war against motion sickness. And having everyone in the same orientation also helps the crew talk with one another.

Mary Roach:
I interviewed this astronaut, Lee Morin, about how troubling it is to try and have a conversation with someone who is upside down when you were right-side-up. “We’re sort of lip-reading all the time without realizing it,” he said. When you go beyond a 45-degree angle, the other person starts to have trouble reading your lips. So it’s considered impolite to carry on a conversation with someone when you are upside down or when you are differently oriented.

Roman Mars:
I love these examples in the fundamentals of otherworldly space design because if you were to recreate that exercise right here in a gravity-based habitat and start from scratch, what would you re-design completely? Would everything simply evolve back to the way it is now? Would US currency still be inexplicably uniform in color and size? Could we get rid of cars if we started over? Could we finally make the steampunkers happy and have a sky full of dirigibles? My guess is that even the poorly-designed and inefficient objects would make a comeback. Because it might just be your dining room table, your crappy, wobbly, “I swear honey that I will fix it soon, I promise”… It might be that dining room table that makes you a happy astronaut.

  1. Hi! I’ve been working my way backwards through the archives to try and find the first time the song at 2:26 in this episode is used, hoping to find out what it is. For me, it’s ‘the sound of 99% Invisible’ and I’d love to score my life to it. Does anyone know what it is?

  2. Chairs. I think chairs need to be drastically redesigned. We use them so much (too much!) but they aren’t usually very comfortable nor do they fit well with our bodies, which I find kind of strange.
