On the twentieth of July, a little before ten at night Houston time, a man stepped off a ladder onto the moon. That was in 1969, and the voice he was talking to when he did it was about forty minutes down the road from here, in a room full of men in short sleeves at what is now the Johnson Space Center. People in Baytown watched it on television like everyone else, though some felt closer to it than most, because Clear Lake was where the whole enterprise lived, and this was and is a town that knows what a night shift looks like when the thing on the board absolutely has to work.
Every anniversary the pictures come back. The boot print in gray dust. The flag with a rod through the top hem, because there is no wind up there to hold it out. The Earth over the horizon, small enough to cover with a thumb. The pictures are of the top of the rocket, or of what the top of the rocket delivered. This is an essay about the bottom.
The Saturn V that left Florida four days before the landing was three hundred and sixty-three feet tall, and most of that height was tank. The first stage, the fat section at the base, carried two of them. One held liquid oxygen. The other held about two hundred thousand gallons of kerosene. Five engines beneath them drank both at a rate that is hard to say out loud; the whole stage was empty in well under three minutes, and in those minutes it threw the rest of the rocket some forty miles up and let go. The stage fell into the Atlantic. Nobody frames a picture of the first stage. It did the ugliest, heaviest, hottest part of the job and then it was done.
Kerosene. Not an exotic thing. The fuel in the lamps of the nineteenth century, the fuel in a jet engine, the fuel in a camp stove. The rocket version is called RP-1, for Rocket Propellant, and it is kerosene refined harder than usual: the sulfur taken out, the ragged ends of the boiling range trimmed off, the molecules that tend to leave carbon crusts held down. That matters because the fuel is pumped through channels in the engine's own walls to keep the metal from melting before it burns, and a fuel that leaves deposits there will kill the engine and everything above it. But it is kerosene. When a Falcon 9 lifts off from the same stretch of Florida coast, its nine engines are burning the same thing, cooled the same way. The most advanced machines people build to leave the planet are lifted by a fuel your great-grandmother might have filled a lamp with.
I want to be careful here, because the temptation is to say that the kerosene in that rocket came from here, and I do not know that. What I can say is what a refinery is, and this town has one of the largest in the country on the channel at its edge, and it has been running for more than a century.
Crude oil comes out of the ground as a mess. It is thousands of different molecules, chains and rings of carbon with hydrogen hung on them, some short enough to be gas, some long enough to be tar. The first thing a refinery does with it is heat it and let it climb a tower. The tower is cooler at the top than at the bottom. The lightest molecules rise farthest before they turn back into liquid; the heaviest barely rise at all. Trays catch them on the way. At the top you draw off gases. A little lower, gasoline. Lower, kerosene: molecules of roughly ten to sixteen carbons, boiling between gasoline and diesel. Lower still, diesel, then the heavy oils, then the sludge at the bottom that becomes the asphalt on the roads. That is distillation, and every refinery on earth does it, and it is the step where kerosene becomes a thing that exists.
Kerosene was the reason there was an oil business at all. The first wells were drilled for lamp oil. Gasoline came off with it, too volatile for a lamp, and for years nobody wanted it. Then the automobile made the nuisance the product, and the jet engine brought kerosene back around, and then someone found that a kerosene flame fed pure oxygen and pointed at the ground could lift a building. The tower did not change through any of that. What changed was what the world found to do with each tray.
So the launch pad is the last step, not the first, and not the second or third either. Before the pad there was a tank car. Before the tank car there was a tower with trays in it and an operator watching temperatures on a board. Before the tower there was a ship that came up a channel. Before the ship there was a well, and before the well there was a sea, warm and shallow and alive, hundreds of millions of years ago, and before the sea there was the sun, which put the energy into the plankton that died and sank and were buried and pressed into the oil that came up the well that went into the ship that came up the channel that went into the tower that gave up the kerosene that went into the tank that lifted three men off the ground. That is the chain. Every link in it is physical. And a great deal of it runs through places that look exactly like the plant on the channel here.
We talk about space as "beyond." Beyond the atmosphere, beyond the Earth, beyond what we are. The word carries a picture of leaving the ground behind, of the ground as the thing escaped from. But the rocket did not escape the ground. It carried the ground with it. It carried an ancient sea, in the form of kerosene, and burned it to get out. The upper stages of the Saturn burned liquid hydrogen, not kerosene, and hydrogen is something industry mostly makes by pulling it out of natural gas, which is the same ancient sea in a lighter form. The plastic in the suits, the insulation on the wires, the film in the cameras that took the picture of the Earth: petrochemicals, every one. The moon landing was not a departure from the world of drums and pipes and towers. It was that world's farthest reach.
That is what this series means when it says that Baytown fuels the world and the world fuels humanity, and it is meant as physics before it is meant as anything about jobs. The people who work behind the fence on the channel are standing at an early link in a chain that ends, some of the time, on the moon. Most of the time it ends somewhere plainer, a highway, a hospital, a kitchen, but it is the same chain, and a person who spends a shift watching a distillation column is doing the same work, in the same kind of place, as the ones whose kerosene lifted Apollo. The night-shift operator on the tower does not think of herself that way, and she should not, because thinking that way at three in the morning is how you miss a reading. But it is true whether she thinks it or not.
There is an old idea, older than the space program, that the atoms in us were made in stars, that they came together into creatures that could look up, and that when we look up the universe is, in some plain sense, looking at itself. Stand on the pier at Bayland Park when the moon is up and the idea is not sentimental at all. The moon is there. The refinery lights are there, on the far side of the water. The moon has been walked on by people who got there on the product of a place like the one making those lights. The universe rearranged a little of itself into plankton, then into oil, then into a town on a ship channel, then into a distillation column and an operator to watch it, so that it could go stand on the moon and look back. That is the sequence of events.
There is a difference between a thing that could act and a thing that is acting, and the rocket is the clearest picture of it anyone has built. Kerosene in a tank car on a siding is the first kind. Kerosene going into five F-1 engines at once, seven and a half million pounds of push, the press stands three and a half miles away shaking so that the reporters held their windows in with their hands, is the second. The tank farms along the channel are full of the first kind, acres of it, and none of it goes anywhere until somebody is at work on it. Turning the one into the other, a shift at a time, is what the town does.
What the moon gave back was mostly a way of seeing. The astronauts were sent to collect rocks and they did, but the thing that changed people was the photographs of the Earth from out there: the one the crew before them brought home of it rising over the moon's edge, and the one a later crew took of the whole disc, all of it, with no lines drawn on it. Weather over the ocean. Night on one side. The whole home in one frame. It is easy to look at those photographs and feel far from a refinery. It is more honest to see the refinery in them: the fuel that got the camera there, the sea that was the fuel, the sun that fed the sea, and the town on the channel, too small to show at that distance, where a good part of the sea gets turned into the world.
There is a smaller thing to say, and it is the one I keep coming back to. The men in short sleeves in that room in Houston were doing shift work. They had boards in front of them with numbers on them, and their job was to know what every number should be and to notice when one was wrong. That is the job on the channel, too. A control room is a control room. The stakes and the audience were different, but the posture was the same: a person, awake, watching a process that cannot be allowed to fail, in a building nobody outside can see into. This town has had thousands of those people for a hundred years. When the moon anniversary comes around it is fair for them to feel, without saying so, that they belong in the picture.
Tonight the moon will come up over the bay, and it will be the same moon. It will lay a path across the water, broken up by the wakes of whatever is moving on the channel, and the path will point, the way it always does, at whoever is standing there looking. The boot prints are still up there, in dust that has no wind to move it. And under the water and the mud and the rock down here, the rest of the sea is still waiting to be lifted.
