Summary

The chapter opens with a striking image of political absurdity: the spacecraft's two toilets are officially restricted by nationality. The Russian toilet is reserved for Russian cosmonauts, while the American, European, and Japanese toilet is off-limits to Russians. The edicts stem from diplomatic disputes that have dragged on for over a year, with space agencies trading threats about access to exercise bikes and food stores. Yet the crew treats the rules as a joke. Shaun announces he's going for a “national pee,” and Roman declares he'll “do one for Russia.” Mission control watches on internal cameras as the crew flagrantly ignores the restrictions, concluding that astronauts are like cats—intrepid, cool, and impossible to herd.

The narration then shifts inward, reflecting on the crew's shared history. They have all spent years in transit—living out of bags, sleeping on friends' sofas between training courses, testing themselves in caves, submarines, and deserts. What unites them is an acceptance of belonging nowhere and everywhere, all in service of reaching this near-mythical craft. The spacecraft is described as a last nationless, borderless outpost straining against the limits of biological life. The crew's unity is absolute and practical: they drink each other's recycled urine and breathe each other's recycled air. They cannot be divided because they literally cannot survive apart.

In the lab, the crew performs a series of virtual-reality tasks designed to measure time perception. A warm, instructive voice asks them to count the seconds a blue square appears on screen. They guess wildly—eight seconds, thirty-six, twenty, three, twenty-nine—and record each estimate. Next, they must hold the square in view for specified durations, then test reaction times by tapping a button when the square appears. The voice praises them each time: “You did great.”

While they work, the spacecraft crosses the equator. The moon's orientation flips, its waxing light shifting from one limb to the other, like a crêpe flipped in a pan. The star field thins as they move into northern skies, away from the dense galactic core toward the Milky Way's outer spirals, where the galaxy fades into nothing. Night gives way to dawn over Venezuela—a blinding spike of light on the horizon that the crew knows well, followed by a gleaming scimitar of silver as the sun rises and the stars vanish.

Then the voice delivers its verdict: the crew was wrong every time. When the square appeared for fifteen seconds, they reported ten. Their counted minute stretched to a minute and a half or more. The narration catalogs their degradation: circadian clocks off pace, limbs mislaid without the feedback of weight, reaction times slowed from split seconds to lumbering two or three seconds. The Omega Speedmaster on their wrists—with its chronograph and tachymeter—has no grasp that this is their seventh orbit since waking. The sun rises and sets like a mechanical toy. Spring becomes autumn in half an hour. The crew's “superfast astronaut uber-being” has gone loose and swimmy, like seaweed or jetsam.

Time itself becomes elastic. Seconds dissolve and lose meaning, shrinking to a dot on a field of white, then bloating without edges. Europe passes below in an afternoon haze—the toe of England kicking at the North Atlantic, the English Channel, Brussels, Amsterdam, Hamburg, Berlin, Denmark leaping toward Norway and Sweden, the Baltic States, and suddenly Russia. The voice laments that the crew exists in all time zones and none at all, that more is asked of their brains than they can manage, that continents lapse and give way to one another, that the beloved earth never stays in their grasp. The ride of their lives will pass in an eyeblink, just as life does to the aging brain. Before they know it, they'll be back in the landing capsule, crashing through the atmosphere engulfed in fire, landing on a vast plain, and being pulled out with pipe-cleaner legs, spluttering monosyllables where once was language.

At the brink of a continent, the light fades. The sea is flat and copper with reflected sun; cloud shadows stretch long on the water. Asia comes and goes. Australia is a dark featureless shape against the last breath of platinum light. The horizon that cracked open with dawn is being erased. Darkness eats at its sharpness, as if the earth is dissolving. The planet turns purple and blurs, a watercolor washing away.

The chapter ends with darkness erasing the earth's horizon, the planet appearing to dissolve like a watercolor.

Character Development

Shaun and Roman are the only named characters in this chapter, and they appear briefly, in the service of humor. Their jokes about “national pees” and “doing one for Russia” reveal a crew that copes with political absurdity through irreverence. They are not defined by their nationalities but by their shared refusal to be divided.

The chapter's deeper character work is collective. The crew is presented as a single entity—
