A wind picked at him, and swirled through his heart; he turned around slowly, like a little planet, like a top about to fall, trying to take it in, to face it. So big, so bright, so windy and vast, so crushingly heavy — the sheer mass of the white world! — and yet with a kind of darkness behind it, as of space’s vacuum, there visible behind the sky. He took off his sunglasses to see what it really looked like, and the glare was so immediate and violent that he had to close his eyes, to cover his face in the crook of his arm; still great white bars pulsed in his vision, and even the afterimage hurt in its blinding intensity. “Wow!” he shouted, and laughed, determined to try it again as soon as the afterimages lessened, but before his pupils had again expanded. So he did, but the second attempt was as bad as the first. How dare you try to look on me as I really am! the world shouted silently. “My God.” With feeling. “Ka wow.”

He put his sunglasses back on his closed eyes, looked out through the bounding afterimages; gradually the primeval landscape of ice and rock restabilized out of the pulsing bars of black and white and neon green. The white and the green; and this was the white. The blank world of the inanimate universe. This place had precisely the same import as the primal Martian landscape. Just as big as it was on Mars, yes, and even bigger, because of the distant horizons, and the crushing gravity; and steeper; and whiter; and windier, ka, it pierced so chill through his parka, even windier, even colder — ah God, like a wind lancing through his heart: the sudden knowledge that Earth was so vast that in its variety it had regions that even out-Marsed Mars itself — that among all the ways that it was greater, it was greater even at being Martian.

He was brought still by this thought. He only stood and stared, tried to face it. The wind died for the moment. The world too was still. No movement, no sound.

When he noticed the silence he began paying attention to it, listening for something, hearing nothing, so that the silence itself somehow became more and more palpable. It was unlike anything he had ever heard before. He thought about it; on Mars he had always been in tents or in suits — always in machinery, except for during the rare walks on the surface he had made in recent years. But then there had always been the wind, or machines nearby. Or he simply hadn’t noticed. Now there was only the great silence, the silence of the universe itself. No dream could imagine it.

And then he began to hear sounds again. The blood in his ears. His breath in his nose. The quiet whir of his thinking — it seemed to have a sound. His own support system this time, his body, with its organic pumps and ventilators and generators. The mechanisms were all still there, provided inside him, making their noises. But now he was free of anything more, in a great silence where he could actually hear himself quite well, just himself on this world alone, a free body standing on its mother earth, free in the rock and ice where it had all begun. Mother Earth — he thought of Hiroko — and this time without the tearing grief that he had felt in Trinidad. When he returned to Mars, he could live like this. He could walk out in the silence a free being, live outdoors in the wind, in something like this pure vast lifeless whiteness, with something like this dark blue dome overhead, the blue a visible exhalation of life itself — oxygen, life’s own color. Up there doming the whiteness. A sign, somehow. The white and the green, except here the green was blue.

With shadows. Among the faint lingering afterimages lay long shadows, running from the west. He was a long way from Jungfraujoch, and considerably lower as well. He turned and began hiking up the Jungfraufirn. In the distance, up the trail, his two companions nodded and turned uphill themselves, hiking fast.

Soon enough they were in the shadow of the ridge to the west, the sun now out of sight for good on this day, and the wind swirling over his back, helping on. Cold indeed. But it was his kind of temperature, after all, and his kind of air, just a nice touch of extra thickness to it; and so despite the weight inside him he began to trudge on up the crunchy hardpack in a little jog, leaning into it, feeling his thigh muscles respond to the challenge, fall into their old lung-gom-pa rhythm, with his lungs pumping hard and his heart as well, to handle the extra weight. But he was strong, strong, and this was one of Earth’s little high regions of Marsness; and so he crunched up the firn feeling stronger by the minute, also appalled, exhilarated — awed — it was a most astonishing planet, that could have so much of the white and so much of the green as well, its orbit so exquisitely situated that at sea level the green burst out and at three thousand meters the white blanketed it utterly — the natural zone of life just that three thousand meters wide, more or less. And Earth rolled right in the middle of that filmy bubble biosphere, in the right few thousand meters out of an orbit 150 million kilometers wide. It was too lucky to be believed.

His skin began to tingle with the effort, he was warm all over, even his toes. Beginning to sweat. The cold air was deliciously invigorating, he felt he was in a pace that he could sustain for hours; but alas, he would not need to; ahead and a bit above lay the snow staircase, with its rope-and-stanchion railing. His guides were making good time ahead of him, hurrying up the final slope. Soon he too would be there, in the little train station/space station. These Swiss, what they thought to build! To be able to visit the stupendous Concordiaplatz, on a day trip from the nation’s capital! No wonder they were so sympathetic to Mars — they were Earth’s closest thing to Martians, truly — builders, terraformers, inhabitants of the thin cold air.

So he was feeling very benevolent toward them when he stepped onto the terrace and then burst into the station, where he began immediately steaming; and when he walked over to his group of escorts and the other passengers who were waiting next to the little train, he was beaming so completely, he was so high, that the impatient frowns of the group (he saw that they had been kept waiting) cracked, and they looked at each other and laughed, shaking their heads as if to say to each other, What can you do? You could only grin and let it happen — they had all been young in the high Alps for the first time, one sunny summer day, and had felt that same enthusiasm — they remembered what it was like. And so they shook his hand, they embraced him — they led him onto the little train and got going, for no matter the event, it was not good to keep a train waiting — and once under way they remarked on his hot hands and face, and asked him where he had gone, and told him how many kilometers that was, and how many vertical meters. They passed him a little hip flask of schnapps. And then as the train went by the little side tunnel that ran out onto the north face of the Eiger, they told him the story of the failed rescue attempt of the doomed Nazi climbers, excited, moved that he was so impressed. And after that they settled into the lit compartments of the train, squealing down through its rough granite tunnel.

Nirgal stood at the end of one car, looking out at the dynamited rock as it flashed past, and then as they burst back into sunlight, up at the looming wall of the Eiger overhead. A passenger walked by him on the way to the next car, then stopped and stared: “Amazing to see you here, T must say.” He had a British accent of some kind. “I just ran into your mother last week.”

Confused, Nirgal said, “My mother?”

“Yes, Hiroko Ai. Isn’t that right? She was in England, working with people at the mouth of the Thames. I saw her on my way here. Quite a coincidence running into you too, I must say. Makes me think I’ll start seeing little red men any second now.”
