Most of us scroll past news about climate, war and space launches feeling both overwhelmed and weirdly numb; Orbital asks what happens if we are forced to look at Earth—our burning, drowning, astonishing Earth—from just far enough away that we can no longer lie to ourselves.
Samantha Harvey’s Orbital compresses 24 hours and 16 laps of the International Space Station into a single, lyrical meditation on six astronauts whose work, grief and jokes unfold against a planet that is exquisitely beautiful and increasingly damaged.
Harvey grounds her fiction in real orbital mechanics—the ISS really circles Earth about every 90 minutes, giving crews 16 sunrises and sunsets per day—mirrors documented astronaut experiences of distorted time and circadian rhythms in microgravity, and threads in a rapidly intensifying typhoon whose behaviour reflects current science on how climate change is boosting the strength of the fiercest tropical storms.
If you like literary fiction that reads like a long prose poem, are curious about the International Space Station, or want climate fiction that’s more elegy than thriller, this Booker-winning novel will probably floor you. If you need a driving plot, clear chapter breaks, or hard sci-fi tech detail, you may admire Orbital more than you actually enjoy it.
Table of Contents
1. Introduction
Samantha Harvey’s Orbital is a 2023 novel set aboard the International Space Station and published by Jonathan Cape in the UK and Grove Atlantic in the US.
At a slender 136–144 pages depending on the edition, it blends literary fiction, philosophical speculation and quiet science fiction, following six astronauts and cosmonauts—Nell (UK), Shaun (US), Chie (Japan), Pietro (Italy), Roman and Anton (Russia)—over the course of a single “day” in orbit.
Structurally, the book is organised into “Orbit minus 1” and then 16 numbered orbits, each roughly corresponding to one 90-minute loop of the station around Earth, echoing the real ISS schedule where “the whipcrack of morning” arrives every ninety minutes.
Since its release it has become a critical and commercial phenomenon, winning the 2024 Booker Prize and the Hawthornden Prize and becoming the first novel set in space to win the Booker; immediately after the prize it topped the UK bestseller lists, selling over 54,000 copies and 20,040 copies in one week alone.
2. Background
Harvey is known for formally adventurous, meditative fiction—The Wilderness, All Is Song, Dear Thief and The Western Wind—often preoccupied with time, faith and the porousness of memory.
In Orbital she takes those preoccupations off-planet, placing them in the cramped, buzzing, multinational environment of the ISS, where astronauts live at around 400 km altitude, travelling roughly 28,000 km/h and circling Earth about 16 times each day.
This isn’t space opera but something closer to Virginia Woolf’s The Waves in microgravity—a comparison several reviewers have explicitly made—where interior monologue and shared consciousness matter more than mission milestones or plot twists.
At the same time, the book is deeply of our moment: its background noise is climate crisis, geopolitical tension and the spectacle of a high-budget lunar fly-by that briefly pushes these working astronauts out of the news cycle and into the strange limbo of “yesterday’s news.”
3. Summary of Orbital
Harvey opens with “Orbit minus 1,” where the six crewmembers hang “in their sleeping bags” while raw space prowls outside “like a panther, feral and primal,” and their dreams—of fractals, blue spheres, familiar faces—start to converge in a kind of shared subconscious.
They are physically close yet existentially alone, suspended “a hand-span away beyond a skin of metal” from a universe that feels both infinite and horribly indifferent; it’s already clear that this will be a novel about perspective and mortality, not docking manoeuvres.
Chie has just had news that her mother has died back on Earth, and no one quite knows how to console a person whose bereavement is happening at 17,500 miles per hour, under the constant shimmer of the aurora.
Orbit 1 and Orbit 2 carry us through their morning routines, and Harvey lets us feel how absurd “morning” becomes when the station sees 16 dawns per terrestrial day and the words “day” and “night” start to lose meaning.
We see Anton and Roman on the Russian exercise equipment, Nell and Pietro on the US treadmill, Chie grinding through her high-resistance bike session, everyone straining against the inevitable muscle loss of microgravity in those mandated two hours of daily exercise that NASA prescribes.
They are seabirds “on a warm day drifting, just drifting” for most of the other 22 hours, bodies becoming strangely undefined even as their minds stay hyper-vigilant.
Almost immediately, news of a four-person lunar mission intrudes—ground control cheerfully reminds them that, for the first time, they are no longer the farthest-flung humans, a crew on its way to the moon has just shot past their altitude, a five-billion-dollar blaze of relevance that makes the station briefly feel obsolete.
Pietro jokes that it’s better to be yesterday’s news than tomorrow’s, because if you’re an astronaut you only become news when you die; the joke lands, but you feel the sting of professional insecurity and mortality underneath.
From here, the book settles into its rhythm: each orbit gives us another sweep of the planet and another angle on the crew’s lives—snatches of backstory, flashes of memory, small irritations and sudden tenderness.
We learn how Roman, Nell and Shaun arrived three months ago in “a module the size of a two-man tent,” endured the long pause of pressure equalisation, then tumbled through the hatch into the weightless embrace of Anton, Pietro and Chie, greeted with bread and salt in a makeshift version of Russian hospitality.
The first sight of Earth—a swirling, jewel-coloured “tourmaline… cantaloupe… lilac orange almond mauve”—hit them like vertigo, accompanied by nausea, headaches and the disorienting sense that their own families, glimpsed on a screen, belonged to “another life.”
We gradually get the details of their work: Shaun’s fragile trays of Arabidopsis (thale cress) that help study how plant roots behave without gravity or normal light cues; Chie’s brain scans and protein crystal growth; Pietro’s obsessive monitoring of microbes that map the station’s evolving ecosystem; Roman and Anton’s maintenance of oxygen generators and cultured heart cells; Nell’s shared duties with Shaun and Chie on mice experiments and flammability tests.
Harvey delights in acronyms—MOP, MPC, WRT, CEO, OESI—yet never lets them overwhelm the fact that these are vulnerable bodies doing delicate work in a lethal environment, one stray bolt away from catastrophe.
A major external thread is the typhoon brewing beneath them in the Western Pacific, first a “skirmish” of winds and then, over just 24 hours, a Category 5 monster whose rapid intensification mirrors terrifying real-world data about storms like this.
From orbit, the crew will track it several times—ascending passes showing a vast white spiral, descending passes revealing darkened coastlines, eventually huge swaths of power loss and lightning flickering in the storm’s eye like a brain misfiring.
Chie’s mother’s funeral is scheduled to happen while the station loops above the other side of Earth; her family has offered to wait until she’s home, but she refuses, needing the ritual to go ahead even if she can be present only in the knowledge that “everything that’s left of my mother is there.”
There’s a heartbreaking dinner scene where the crew share out Nell’s last chocolate-coated honeycomb, talk about the sweets of their childhood—dagashiya candy in Japan, ten-pence mix-ups in England, Galatine and korovka milk sweets in Italy and Russia—and the word “home” settles among them like a third, unacknowledged presence.
Even here Harvey keeps her tone light with banter—Shaun teasing that Russia is “unduly afflicted with a love of condensed milk,” Roman insisting the rest of the world doesn’t put enough condensed milk in things—but it’s a comedy that’s clinging to the edge of grief.
Running underneath all this is Anton’s quiet fear of a lump on his neck that he keeps touching and half-hiding with his collar; in fragments we realise he’s imagining what would happen if it proved malignant up here, and later—when the typhoon montage is at its most intense—Harvey lets him feel a tiny stab of dizziness that he pointedly ignores.
Pietro, by contrast, is often the one to articulate the philosophical spine of the book; midway through he muses that “if you could get far enough away from the earth you’d be able finally to understand it,” a line reviewers have rightly flagged as a kind of thesis statement.
The orbits pass: they photograph river deltas, wildfire smoke plumes, the dark scar of a recent war zone; they fix the toilet-that-always-breaks; Nell notes how healthy she has felt in space, how long it’s been since she had even a cold, even as Anton’s lump throbs quietly in the background.
Soundlessly, solar flares lash out, sending proton storms towards Earth, and Harvey has a marvelous passage likening the sun to a dragon whose “fury” paradoxically cocoons them by pushing away some of the most dangerous cosmic radiation—again, consistent with heliophysics research on how solar activity can modulate high-energy cosmic rays.
As the book moves into the later orbits—13, 14, 15—it becomes, if anything, more interior: Anton thinking about his grown children and the poverty of his Soviet childhood; Shaun remembering an evangelical youth in small-town America; Nell worrying about her brother’s email reporting a bout of flu and realising how utterly separate her body now feels from the world’s illnesses.
Chie, waiting for the funeral, drifts in and out of memories of her parents’ garden and of the dagashiya shops that “tend to have been turned into museums” now, small losses hinting at the larger losses the typhoon is about to tally up.
Meanwhile, the typhoon slams into the Mariana Islands and then barrels toward the Philippines; we’re told of five-metre storm surges that “engulf” islands like Tinian and Saipan, windows blown out, walls buckling, the sea itself acting like “cluster bombs,” and you can’t help hearing the echo of contemporary reports linking such intensification to warmer oceans.
There is no single cinematic climax—no collision, no decompression, no heroic repair—but rather a thickening braid of awareness: of planetary vulnerability, of each other’s private sorrows, of their own odd role as both scientists and witnesses.
The final orbits soften their focus, and in Orbit 16 the novel closes with the crew still aloft, still “in low Earth orbit, watching as the planet turns beneath them,” their spacecraft continuing its endless path through the dark; nothing is resolved, yet everything feels newly seen.
The ending is therefore deliberately anti-climactic in plot terms but climactic in perception: everyone and everything is exactly where it was at the start—six humans in a metal shell, 8 billion humans on a warming planet below—but our gaze has been re-educated.
4. Orbital Analysis
4.1 Orbital Characters
Harvey’s six-person ensemble is carefully balanced: two Russians (Roman, Anton), one Brit (Nell), one American (Shaun), one Italian (Pietro), one Japanese (Chie), reflecting the genuine international mix of ISS crews since continuous occupancy began in 2000.
Roman, a veteran cosmonaut, often reads like the station’s quiet moral centre—he brings bread and “salt cubes” through the hatch, teaches the rookies how to move in microgravity, worries about a missing screw in the Russian module while storms rage unseen below.
Anton feels like the most fragile: his insomnia, his jet-lagged mind and that neck lump are never dramatised into a medical subplot, but they hover as a reminder that spaceflight happens inside fallible, ageing bodies, not sleek machines.
Nell, England’s representative, is often the perspective through which we feel both wonder and estrangement—her body feels young and painless in space, she remarks on how rarely she’s been ill up here, yet she frets about the flu-ridden brother she can do nothing for, thousands of kilometres beneath.
Shaun, the American, is the joker and sometime irritant, floating “above them like an angel” at breakfast, making irreverent comments about American Christians getting everywhere, yet he’s also the one who instinctively hands Chie a napkin when she mentions her parents’ garden and her mother’s funeral.
Pietro is the romantic and philosopher, linking Duke Ellington on his treadmill to memories of “wild mint meadows,” musing about understanding Earth from far away, and dreaming of the “pointless” rug he wants back home because it represents surplus, comfort, a life that is not all function.
Chie, finally, carries the heaviest emotional load with her off-stage funeral, yet Harvey writes her understatedly: she talks about dagashiya candy, notes the disappearance of those shops into museums, and quietly says “I can’t stop thinking of home,” which hits harder than any big speech.
None of them gets a full realist backstory; instead, their histories arrive in shards—dreams, half-remembered arguments, sensory flashbacks—mirroring how memory actually works, especially under fatigue, microgravity and disrupted sleep cycles.
That fragmentation can make them feel elusive, which some readers and reviewers have criticised as a lack of character depth, yet it also gives the novel its eerie sense of a shared, drifting consciousness.
4.2 Orbital Themes and Symbolism
The most obvious theme is perspective: the idea that distance—250 miles straight up, 16 orbits in a day—can both sharpen and distort our view of human affairs.
The station itself becomes a symbol of global interdependence: Russians sharing soup and korovka, Americans bringing honeycomb, Japanese and British crew talking about convenience stores and ten-pence sweets, all of them reliant on each other’s experiments, maintenance and emotional steadiness.
Climate change is never named as a thesis but saturates the book—through the super-typhoon, wildfires, melting ice, glowing night-time grids of overbuilt cities—and aligns Orbital with contemporary “cli-fi” that uses near-future or present-day scenarios rather than dystopian extremes.
The typhoon, in particular, works as a symbol of how small local decisions add up to global consequences: the astronauts look down at it as if they’re weathermen, but the storm is powered by the kind of warmer waters and rising sea levels that current IPCC assessments and NOAA research warn will make Category 4 and 5 storms both more intense and more damaging.
There is also a strong undercurrent of theological questioning; James Wood’s New Yorker piece is right to say the book circles the question of God, yet often does so in the negative, with the crew half-joking that maybe Earth itself is the afterlife—“the earth, from here, is like heaven”—or that raw space is the real sublime, a “panther, feral and primal.”
Symbolically, the 16 orbits trace a kind of liturgy: repeated passings over the same continents at different angles and times of day, like revisiting the same questions about love, duty, grief and responsibility from slightly altered vantage points until something clicks.
Even the small running jokes—about condensed milk, rugs, American Christians—act as ritualised ways of managing fear, a human habit as old as seafaring and as new as commercial spaceflight.
5. Evaluation
Harvey’s biggest strength, to my mind, is the prose: almost any paragraph can be lifted and read as a self-contained fragment of lyric essay, whether she’s describing Africa as an “overflowing-fruit-bowl continent of chaotic perfection” or lightning as a “silver-blue silent flower.”
She’s also remarkably good at stitching together the mundane and the cosmic—loose screws, clogged air filters, chocolate honeycomb, MRI scans and heart-cell cultures—into a pattern that feels both believable as ISS life and resonant as metaphor.
On a structural level, the tight 24-hour frame and the orbit-by-orbit chapters keep what could have been a formless meditation taut enough that we never entirely lose track of time, even as the characters themselves struggle to tell “how long a minute” really is up here.
Critics who love the book, like Alexandra Harris in The Guardian and Sara Collins on the Booker panel, praise exactly this marriage of rhythm and reflection, arguing that the real beauty of Orbital lies “deep in its rhythms and structures” and in its ability to make Earth “something deeply resonant.”
On the other hand, there are genuine weaknesses or at least sticking points for many readers: the lack of a central plot engine, the relative sameness of the narrative voice across characters, and prose that can tilt, depending on your tolerance, from beautiful to “dangerously over-hyped” or even “pretentious, boring and banal.”
Some reviewers have admitted losing engagement in the second half, saying that while the opening dazzles with “breathtaking imagery and profound ideas,” later orbits feel like variations on a theme rather than escalations.
Personally, I think that plateau is intentional: life on a long-duration mission doesn’t build to neat scenes, it recurs and loops, and Harvey is trying to make us feel that recursiveness in our own reading bodies—though it does mean this is a novel that rewards patient, immersive reading more than quick consumption.
Compared with similar works—say, Emily St. John Mandel’s Sea of Tranquility (for philosophical time-bending) or Claire Keegan’s very short, very concentrated novellas—Orbital sits closer to Woolf and to the modernist long paragraph than to conventional sci-fi, despite its setting.
In terms of adaptation, there is currently no announced TV or film version of Orbital; based on available information, no production company has publicly acquired or developed the screen rights yet, so any comparison with a specific series or box office is purely speculative and would risk fabrication.
Interestingly, Jeff Foust at The Space Review contrasts Harvey’s quiet, interior ISS with the thriller-style film I.S.S. (2024), which uses the same setting for a geopolitical crisis, underscoring how radically different stories can be told in the same orbital corridor.
If Orbital ever does make it to screen, it will probably succeed not as an action spectacle but as something like Solaris in low Earth orbit: slow, contemplative, full of Earth-view montages and voice-over, more likely to win festival prizes than Marvel-style revenue.
6. Personal Insight
What lingers after Orbital, for me, is how educational its perspective is without ever sounding like a lesson.
We live at a moment when students can scroll from ISS livestreams to wildfire footage to storm trackers in the same minute, yet still feel oddly disconnected from what they’re seeing; Harvey’s astronauts show what happens when you cannot look away, when your literal job is to photograph “Locations Of Extra-Special Interest” like hurricanes, fires and flooding river mouths, over and over again.
From a teaching standpoint, Orbital pairs beautifully with real-world data sets: NASA’s ISS Earth-observing missions; NOAA’s projections that very intense Category 4–5 storms will likely become more frequent and more damaging this century; recent studies suggesting human-driven warming has already increased Atlantic hurricane wind speeds by around 18 mph in just six years.
Using passages from the novel alongside climate dashboards or satellite images can help students see that climate change is not an abstract graph but a lived, time-bound process—one orbit you’re looking at Mauritania at sunset, the next at the Philippines under a super-typhoon, the next at polar ice thinning at the margins.
Equally, the book opens doors into discussions of time perception and mental health in extreme environments: we can connect its descriptions of warped minutes and sleep-starved minds to current research on how microgravity and non-24-hour light cycles disrupt circadian rhythms and stress responses, and then relate that back to more everyday issues like shift work, jet lag or excessive screen time.
7. Orbital Quotes
“Rotating about the earth in their spacecraft they are so together, and so alone, that even their thoughts… at times convene.”
“Raw space is a panther, feral and primal.”
“Up here in microgravity you’re a seabird on a warm day drifting, just drifting.”
“The earth, from here, is like heaven. It flows with colour.”
“Do you know what I’ll look forward to getting back to…? Things I don’t need, that’s what. Pointlessness. Some pointless ornament on a shelf. A rug.”
8. Conclusion
In the end, Orbital is less a story “about” space than a story that uses space to refract everything we already know and fear about Earth: climate volatility, political estrangement, familial love, the quiet heroism of people doing unglamorous work out of sight.
It won major prizes not because of its premise—“six astronauts on the ISS for a day” could easily have been gimmicky—but because of the intensity and tenderness with which Harvey attends to both the planet and the people looping around it, turning orbital mechanics into moral and emotional geometry.
I would recommend Orbital wholeheartedly to readers of literary fiction, climate fiction, space-curious non-scientists, and anyone who enjoyed introspective, structurally experimental novels like The Waves or To the Lighthouse and is willing to follow that tradition out beyond the atmosphere.
If, however, you prefer tight plots, crisp character arcs and detailed hardware porn, you may find yourself bouncing off this book, even as you recognise the craft behind its sentences.
For those who do sync with it, though, Orbital can be quietly life-reorienting: for a few hundred pages you inhabit a vantage point from which every coastline, every storm and every sleeping city is both heartbreakingly small and overwhelmingly precious—and once you’ve seen the world that way, it’s hard to go back.
