Later, Armstrong would say, “That first hour on the moon was hardly the time for long thoughts; we had specific jobs to do. Of course the sights were simply magnificent, beyond any visual experience that I had ever been exposed to,” and Aldrin would describe it as “a unique, almost mystical environment.” In fact, there is an edge of the unexplained to their reactions. Their characteristic matter-of-fact response is overcome occasionally by swoops of hyperbole. And to everyone’s slight surprise, they were almost two hours late for their EVA. Their estimate of time was off by close to fifty percent. For astronauts that was an error comparable to a carpenter mistaking an eight-foot stud for a twelve-foot piece. If a carpenter can look at a piece of wood and guess its length to the nearest quarter-inch, it is because he has been working with lengths all his life. Equally, people in some occupations have a close ability to estimate time.
With astronauts, whose every day in a simulator was a day laid out on the measure of a time-line, the estimate of time elapsed had to become acute. Armstrong and Aldrin had consistently fulfilled their tasks in less time than was allotted. Now, curiously, they fell behind, then further behind. There were unexpected problems of course—it took longer to bleed the pressure out of the Lunar Module than had been anticipated, and the cooling units in the backpacks were sluggish at first in operation, but whether from natural excitement and natural anxiety, or an unconscious preoccupation with lunar phenomena so subtle that it is just at the edge of their senses, any extract from the transcript at this point where they are helping to adjust the Portable Life Support System on each others’ backs shows real lack of enunciation. Nowhere else do the NASA stenographers have as much difficulty with where one voice ends and another begins.

PAO: That was a Buzz Aldrin comment.
The hint is faint enough, but the hint exists—something was conceivably interfering with their sense of order. Could it have been the lunar gravity? Clock-time was a measure which derived from pendulums and spiral springs, clock-time was anchored right into the tooth of earth gravity—so a time might yet be coming when psychologists, not geologists, would be conducting experiments on the moon. Did lunar gravity have power like a drug to shift the sense of time?
Armstrong was connected at last to his PLSS. He was drawing oxygen from the pack he carried on his back. But the hatch door would not open. The pressure would not go low enough in the Lem. Down near a level of one pound per square inch, the last bit of man-created atmosphere in Eagle seemed to cling to its constituency, reluctant to enter the vacuums of the moon. But they did not know if they could get the hatch door open with a vacuum on one side and even a small pressure on the other. It was taking longer than they thought. While it was not a large concern since there would be other means to open it—redundancies pervaded throughout—nonetheless, a concern must have intruded: how intolerably comic they would appear if they came all the way and then were blocked before a door they could not crack. That thought had to put one drop of perspiration on the back of the neck. Besides, it must have been embarrassing to begin so late. The world of television was watching, and the astronauts had exhibited as much sensitivity to an audience as any bride on her way down the aisle.
It was not until nine-forty at night, Houston time, that they got the hatch open at last. In the heat of running almost two hours late, ensconced in the armor of a man-sized spaceship, could they still have felt an instant of awe as they looked out that open hatch at a panorama of theater: the sky is black, but the ground is brightly lit, bright as footlights on the floor of a dark theater. A black and midnight sky, yet on the moon ground, “you could almost go out in your shirt-sleeves and get a suntan,” Aldrin would say. “I remember thinking, ‘Gee, if I didn’t know where I was, I could believe that somebody had created this environment somewhere out in the West and given us another simulation to work in.’ ” Everywhere on that pitted flat were shadows dark as the sky above, shadows dark as mine shafts.
What a struggle to push out from that congested cabin, now twice congested in their bulky-wham suits, no feeling of obstacle against their flesh, their sense of touch dead and numb, spaceman body manipulated out into the moon world like an upright piano turned by movers on the corner of the stairs.
“You’re lined up on the platform. Put your left foot to the right a little bit. Okay, that’s good. Roll left.”
Armstrong was finally on the porch. Could it be with any sense of an alien atmosphere receiving the fifteen-layer encapsulations of the pack and suit on his back? Slowly, he climbed down the ladder. Archetypal, he must have felt, a boy descending the rungs in the wall of an abandoned well, or was it Jack down the stalk? And there he was on the bottom, on the footpad of the leg of the Lem, a metal plate perhaps three feet across. Inches away was the soil of the moon. But first he jumped up again to the lowest rung of the ladder. A couple of hours later, at the end of the EVA, conceivably exhausted, the jump from the ground to the rung, three feet up, might be difficult in that stiff and heavy space suit, so he tested it now. “It takes,” said Armstrong, “a pretty good little jump.”
Now, with television working, and some fraction of the world peering at the murky image of this instant, poised between the end of one history and the beginning of another, he said quietly, “I’m at the foot of the ladder. The Lem footpads are only depressed in the surface about one or two inches, although the surface appears to be very very fine-grained as you get close to it. It’s almost like a powder.” One of Armstrong’s rare confessions of uneasiness is focused later on this moment. “I don’t recall any particular emotion or feeling other than a little caution, a desire to be sure it was safe to put my weight on that surface outside Eagle’s footpad.”
Did his foot tingle in the heavy lunar overshoe? “I’m going to step off the Lem now.”
Did something in him shudder at the touch of the new ground? Or did he draw a sweet strength from the balls of his feet? Nobody was necessarily ever going to know.
“That’s one small step for a man,” said Armstrong, “one giant leap for mankind.” He had joined the ranks of the forever quoted. Patrick Henry, Henry Stanley and Admiral Dewey moved over for him.

Now he was out there, one foot on the moon, then the other foot on the moon, the powder like velvet underfoot. With one hand still on the ladder, he comments, “The surface is fine and powdery. I can … I can pick it up loosely with my toe.” And as he releases his catch, the grains fall back slowly to the soil, a fan of feathers gliding to the floor. “It does adhere in fine layers like powdered charcoal to the sole and sides of my boots. I only go in a small fraction of an inch. Maybe an eighth of an inch. But I can see the footprints of my boots and the treads in the fine sand particles.”
Capcom: “Neil, this is Houston. We’re copying.”
Yes, the
y would copy. He was like a man who goes into a wrecked building to defuse a new kind of bomb. He talks into a microphone as he works, for if a mistake is made, and the bomb goes off, it will be easier for the next man if every detail of his activities has been mentioned as he performed them. Now, he released his grip on the ladder and pushed off for a few steps on the moon, odd loping steps, almost thrust into motion like a horse trotting up a steep slope. It could have been a moment equivalent to the first steps he took as an infant for there was nothing to hold onto and he did not dare to fall—the ground was too hot, the rocks might tear his suit. Yet if he stumbled, he could easily go over for he could not raise his arms above his head nor reach to his knees, his arms in the pressure bladder stood out before him like sausages; so, if he tottered, the weight of the pack could twist him around, or drop him. They had tried to shape up simulations of lunar gravity while weighted in scuba suits at the bottom of a pool, but water was not a vacuum through which to move; so they had also flown in planes carrying two hundred pounds of equipment on their backs. The pilot would take the plane through a parabolic trajectory. There would be a period of twenty-two seconds at the top of the curve when a simulation of one-sixth gravity would be present, and the two hundred pounds of equipment would weigh no more than on the moon, no more than thirty-plus pounds, and one could take loping steps down the aisle of the plane, staggering through unforeseen wobbles or turbulence. Then the parabolic trajectory was done, the plane was diving, and it would have to pull out of the dive. That created the reverse of one-sixth gravity—it multiplied gravity by two and a half times. The two hundred pounds of equipment now weighed five hundred pounds and the astronauts had to be supported by other men straining to help them bear the weight. So simulations gave them time for hardly more than a clue before heavy punishment was upon them. But now he was out in the open endless lunar gravity, his body and the reflexes of his life obliged to adopt a new rhythm and schedule of effort, a new disclosure of grace.
Still, he seemed pleased after the first few steps. “There seems to be no difficulty in moving around as we suspected. It’s even perhaps easier than the simulations …” He would run a few steps and stop, run a few steps and stop. Perhaps it was not unlike directing the Lem when it hovered over the ground. One moved faster than on earth and with less effort, but it was harder to stop—one had to pick the place to halt from several yards ahead. Yes, it was easier once moving, but awkward at the beginning and the end because of the obdurate plastic bendings of the suit. And once standing at rest, the sense of the vertical was sly. One could be leaning further forward than one knew. Or leaning backward. Like a needle on a dial one would have to oscillate from side to side of the vertical to find position. Conceivably the sensation was not unlike skiing with a child on one’s back.
It was time for Aldrin to descend the ladder from the Lem to the ground, and Armstrong’s turn to give directions: “The shoes are about to come over the sill. Okay, now drop your PLSS down. There you go. You’re clear.… About an inch clearance on top of your PLSS.”
Aldrin spoke for future astronauts: “Okay, you need a little bit of arching of the back to come down …”
When he reached the ground, Aldrin took a big and exuberant leap up the ladder again, as if to taste the pleasures of one-sixth gravity all at once. “Beautiful, beautiful,” he exclaimed.
ARMSTRONG: Isn’t that something. Magnificent sight out here.
ALDRIN: Magnificent desolation.
They were looking at a terrain which lived in a clarity of focus unlike anything they had ever seen on earth. There was no air, of course, and so no wind, nor clouds, nor dust, nor even the finest scattering of light from the smallest dispersal of microscopic particles on a clear day on earth, no, nothing visible or invisible moved in the vacuum before them. All light was pure. No haze was present, not even the invisible haze of the finest day—therefore objects did not go out of focus as they receded into the distance. If one’s eyes were good enough, an object at a hundred yards was as distinct as a rock at a few feet. And their eyes were good enough. Just as one could not determine one’s altitude above the moon, not from fifty miles up nor five, so now along the ground before them no distance was real, for all distances had the faculty to appear equally near if one peered at them through blinders and could not see the intervening details. Again the sense of being on a stage or on the lighted floor of a room so large one could not see where the dark ceiling began must have come upon them, for there were no hints of gathering evanescence in ridge beyond ridge; rather each outline was as severe as the one in front of it, and since the ground was filled with small craters of every size, from antholes to potholes to empty pools, and the horizon was near, four times nearer than on earth and sharp as the line drawn by a pencil, the moon ground seemed to slope and drop in all directions “like swimming in an ocean with six-foot or eight-foot swells and waves,” Armstrong said later. “In that condition, you never can see very far away from where you are.” But what they could see, they could see entirely—to the depth of their field of view at any instant their focus was complete. And as they swayed from side to side, so a sense of the vertical kept eluding them, the slopes of the craters about them seeming to tilt a few degrees to one side of the horizontal, then the other. On earth, one had only to incline one’s body an inch or two and a sense of the vertical was gone, but on the moon they could lean over, then further over, lean considerably further over without beginning to fall. So verticals slid and oscillated. Rolling from side to side, they could as well have been on water, indeed their sense of the vertical was probably equal to the subtle uncertainty of the body when a ship is rolling on a quiet sea. “I say,” said Aldrin, “the rocks are rather slippery.”
They were discovering the powder of the moon soil was curious indeed, comparable in firmness and traction to some matter between sand and snow. While the Lem looked light as a kite, for its pads hardly rested on the ground and it appeared ready to lift off and blow away, yet their own feet sometimes sank for two or three inches into the soft powder on the slope of very small craters, and their soles would slip as the powder gave way under their boots. In other places the ground was firm and harder than sand, yet all of these variations were to be found in an area not a hundred feet out from the legs of the Lem. As he explored his footing, Aldrin sent back comments to Mission Control, reporting in the rapt professional tones of a coach instructing his team on the conditions of the turf in a new plastic football field.
Meanwhile Armstrong was transporting the television camera away from the Lem to a position where it could cover most of their activities. Once properly installed, he revolved it through a full panorama of their view in order that audiences on earth might have a clue to what he saw. But in fact the transmission was too rudimentary to give any sense of what was about them, that desert sea of rocks, rubble, small boulders, and crater lips.
Aldrin was now working to set up the solar wind experiment, a sheet of aluminum foil hung on a stand. For the next hour and a half, the foil would be exposed to the solar wind, an invisible, unfelt, but high-velocity flow of noble gases from the sun like argon, krypton, neon and helium. For the astronauts, it was the simplest of procedures, no more difficult than setting up a piece of sheet music on a music stand. At the end of the EVA, however, the aluminum foil would be rolled up, inserted in the rock box, and delivered eventually to a laboratory in Switzerland uniquely equipped for the purpose. There any noble gases which had been trapped in the atomic lattice of the aluminum would be baked out in virtuoso procedures of quantitative analysis, and a closer knowledge of the components of the solar wind would be gained. Since the solar wind, it may be recalled, was diverted by the magnetosphere away from the earth it had not hitherto been available for casual study.
That was the simplest experiment to set up; the other two would be deployed about an hour later. One was a passive seismometer to measure erratic disturbances and any periodic vibrations, as well as moonquakes, and the impact o
f meteors in the weeks and months to follow; it was equipped to radio this information to earth, the energy for transmission derived from solar panels which extended out to either side, and thereby gave it the look of one of those spaceships of the future with thin extended paperlike wings which one sees in science fiction drawings. In any case it was so sensitive that the steps of the astronauts were recorded as they walked by. Finally there was a Laser Ranging Retro-Reflector, an LRRR (or LRQ, for L R-cubed), and that was a mirror whose face was a hundred quartz crystals, black as coal, cut to a precision never obtained before in glass—one-third of an arc/sec. Since each quartz crystal was a corner of a rectangle, any ray of light striking one of the three faces in each crystal would bounce off the other two in such a way that the light would return in exactly the same direction it had been received. A laser beam sent up from earth would therefore reflect back to the place from which it was sent. The time it required to travel this half-million miles from earth to moon round trip, a journey of less than three seconds, could be measured so accurately that physicists might then discern whether the moon was drifting away from the earth a few centimeters a year, or (by using two lasers) whether Europe and America might be drifting apart some comparable distance, or even if the Pacific Ocean were contracting. These measurements could then be entered into the caverns of Einstein’s General Theory of Relativity, and new proof or disproof of the great thesis could be obtained.
