Summary

Chapter 13 opens with Nell engaged in a mundane but physically demanding task: hauling cargo bags of waste and used items into stowage. Everything that won't return to Earth—food waste, used clothing, toiletries, nail and hair cuttings—is being packed for the resupply craft arriving the following week. When that craft undocks in two months, the entire load will combust in the atmosphere, with any surviving debris beginning a long life in Earth orbit. The work is described as a three-dimensional puzzle, cramped and physical, with Nell pushing bags down with her feet and strapping them fast before they can float away.

The cramped conditions remind Nell of a caravanning holiday from when she was four or five, not long before her mother died. Her mother had packed bags into every available cupboard and trunk, industriously, as if they were moving in rather than on holiday. Nell recalls that her family moved around often, and her father later mentioned a time between homes, though he never mentioned a caravan.

Looking out the window, Nell observes northern Europe, the south coast of Ireland where her husband lives, and England, before the orbit carries them south through Europe. The colours shift as they travel—browns lighten, greens emerge in various shades, and the Nile Delta appears as a rich purplish-green spillage. Africa lies beneath them in what Nell thinks of as abstract batik.

This view prompts a memory of a conversation with her husband. He had compared Africa from space to a late Turner painting—near-formless landscapes of thick impasto shot with light. He told her he'd never be where she is because he needs firm ground, needs stability inside and out. He described two kinds of people: those who complicate their inner lives and therefore need outer simplicity (a house, a field, some sheep), and those who simplify their inner lives so that outer things can be ambitious and limitless (a spaceship, a universe). Nell had countered that nobody has limitlessness. When he asked if she'd go to Mars—knowing the journey would be at least three years and she might never return—she answered without hesitation. He admitted he'd want to want to, but feared he'd be the one who cracked up and threatened the mission.

Nell places the final cargo bag in the airlock alongside the spacesuits, which she describes as ghostly floating things. She wonders if she'll ever go back outside in one. This prompts a memory of night freediving through bioluminescence, where stars seemed to spark all around, and her body and the water became continuous with one another.

The chapter closes with Nell's reflection on her marriage. She and her husband exchange photographs almost daily—his views of the lough, the mountain, sheep, icicles, sunsets, and once a night sky with a drawn circle marking where their spacecraft was travelling. She sends him pictures of Earth, of Ireland (always partly under cloud), of her on a bike amid the clutter of the modules. The truth, she reflects, is that he always knows where to find her: her exact location is a publicly known, closely mapped fact, an orbit predictable to the millisecond. She could be in any of seventeen modules, but nowhere else. She is, she admits, trapped. His whereabouts are less known; he could be anywhere. Of their six-year relationship, they've been married for five; of those, she's been in training for four, and they've spent only a handful of months together. He moved into his inherited family home in Ireland last year, a country she barely knows, a land as mythical to her as the earth views are to him. When she asked who is more unknown, he replied that both are differently but equally unknown—her mind full of acronyms, his full of sheep ailments.

Character Development

Nell emerges as someone who has chosen a life of outer ambition and inner simplicity. Her willingness to go to Mars without hesitation reveals a temperament fundamentally different from her husband's. Her memories—of freediving, of her mother packing bags—show a person who processes her present experience through bodily and childhood memory. The chapter also reveals her vulnerability: she admits she is trapped in her known orbit, and that Ireland is as mythical to her as space is to her husband.

The husband (unnamed) is developed entirely through Nell's memory and reflection. He is a man who needs firm ground, who complicates his inner life and therefore needs outer simplicity. His self-awareness is striking: he knows he'd be the one to crack up on a Mars mission. His photographs—of sheep, icicles, the lough—ground him in a particular, local world.

Anton appears only briefly, gliding past Nell in a doorway, a small moment of physical proximity in the cramped ship.

Themes, Symbols, or Motifs

Freediving as metaphor for spaceflight: Nell repeatedly connects the two experiences—the slow suspended movement, the constricted spaces, the sense of being carried. The night freediving through bioluminescence becomes a symbol of bodily continuity and tranquil mind, qualities she seeks in space.

Claustrophobia and agoraphobia coexisting: The chapter explicitly notes that looking out from the cramped ship transforms claustrophobia into agoraphobia, or both at once. The labyrinthine interior and the vast exterior are two sides of the same experience.

Waste and debris in orbit: The cargo bags of waste destined to burn up in the atmosphere symbolise the material traces of human life in space—the mundane accumulation of living that must be disposed of.

Inner vs. outer simplicity: The husband's distinction between two kinds of people structures the chapter's meditation on ambition, risk, and temperament. Nell has simplified her inner life to enable outer limitlessness; her husband needs outer simplicity to manage inner complexity.

Mutual unknowability: The chapter's closing reflection—that both are equally unknown to each other—is the emotional core. Despite the photo exchange, despite the mapped orbit, they remain mysteries to one another.

Ireland as mythical landscape: For Nell, Ireland is a land of reeds and bog cotton and gorse, a country she barely knows, as mythical to her as the earth views are to her husband.

Why This Chapter Matters

This chapter deepens the novel's exploration of what it means to be in orbit—both literally and metaphorically. It grounds Nell's cosmic perspective in personal memory and relationship, showing how the vast view from space coexists with the most intimate human concerns. The chapter also complicates the idea of freedom: Nell is trapped in a predictable orbit while her husband, grounded on Earth, is the one whose whereabouts are unknown. The meditation on inner and outer simplicity offers a framework for understanding the different temperaments that choose (or decline) a life in space. And the closing reflection on mutual unknowability speaks to the novel's broader interest in how we can be profoundly connected to others while remaining fundamentally mysterious to them.

Study Questions and Answers

1. How does the freediving metaphor shape Nell's understanding of spaceflight?

Nell repeatedly compares spaceflight to freediving: the slow suspended movement, the constricted spaces of the ship resembling a wreck, the sense of being calmly carried. The night freediving through bioluminescence—where her body and the water became continuous—represents an ideal state of bodily and mental integration that she seeks to recreate in space. The metaphor also captures the paradox of the experience: the cramped interior and the vast exterior, claustrophobia and agoraphobia coexisting.

2. What does the husband's distinction between inner and outer simplicity reveal about the two characters' relationships to risk and ambition?

The husband describes two kinds of people: those who complicate their inner lives and need outer simplicity, and those who simplify their inner lives so outer things can be ambitious and limitless. He places himself in the first category—needing a house, a field, some sheep—while Nell belongs to the second, able to swap a house for a spaceship. This distinction explains why Nell would go to Mars without hesitation while her husband admits he'd be the one to crack up on the journey. It also suggests that their different temperaments are not a matter of courage but of fundamental psychological structure.

3. How does the chapter complicate the idea of freedom through the photo exchange?

The photo exchange seems to connect the couple across distance, but it also reveals an asymmetry. Nell's location is publicly mapped and predictable to the millisecond; she is trapped in her orbit. Her husband's whereabouts are unknown; he could be anywhere. Yet Nell reflects that both are equally unknown to each other—her mind full of acronyms, his full of sheep ailments. The chapter thus complicates the simple opposition between the astronaut's freedom and the grounded person's constraint: both are free and both are trapped in their own ways.
