Loneliness and connection

Loneliness and connection are linked conditions in the novel, not simple opposites: characters reach toward one another, but contact cannot undo separation, restore the dead, or guarantee that anyone is listening. Through Sully’s relationships with Devi and her crewmates, her work on Aether’s communications system, and her radio exchange with an isolated survivor on Earth, connection appears as a fragile practice—sometimes a presence, sometimes a task, sometimes only the knowledge that another person is there.

Forms of Isolation

Isolation takes different forms for Sully and Devi. In a darkened compartment, Devi tells Sully about a recurring dream of her family’s kitchen in Kolkata. In it, her parents and brothers gather for a meal, until the scene gives way to the knowledge that they are gone and that she is alone. The dream offers a temporary return to family life but makes waking separation newly painful. Its repetition shows how memory can preserve intimacy while also renewing the awareness of loss.

Sully cannot promise that everything will be all right or find an easy way to bridge the distance Devi has fallen into. Instead, the two lie beside one another, and Sully lets her foot rest against Devi’s. Their quiet proximity does not resolve Devi’s grief; it gives them a form of contact that asks nothing of either woman by way of explanation. Later, as they sleep, their limbs overlap. The scene makes connection physical and mutual without suggesting that closeness can erase what has happened to them.

Sully also carries a separate isolation in the image of Lucy’s photograph, pinned alone on a wall with empty space around it. She touches her daughter’s face, but the photograph cannot answer or close the distance between them. The image concentrates a wider separation: Sully is far from the family life she left behind, and remembering Lucy brings both attachment and absence into the present.

Grief, Work, and the Crew

After Devi dies during a spacewalk, Sully’s isolation becomes inseparable from the circumstances of that loss. She repeatedly imagines different outcomes, including reaching the airlock in time or recognizing the failing carbon-dioxide scrubber sooner, but these imagined alternatives bring no relief. The event returns in nightmares, and she understands that she remains aboard Aether while Devi is gone. Her response is not a quick movement from grief to recovery: she tries to endure the day, turns away visiting crewmates with the promise of tomorrow, and then gets up to resume the work the mission requires.

Work offers concentration without making the loss disappear. Sully and Thebes focus on bringing the replacement communications system online, avoiding discussion of the spacewalk while they attend to the task. Yet Sully recognizes that Devi’s death is not hers alone to bear. The others watched the event through helmet cameras, and its replay occupies the crew as well. At a meal, the remaining crewmembers gather around the last saved dish of shepherd’s pie; Ivanov takes Tal’s and Harper’s hands, and the others follow. The shared meal and gesture of holding hands do not explain the loss. They make the crew’s collective mourning visible, including to Sully, who had been treating herself as if she were grieving alone.

The repair work also has a practical purpose: Sully and Thebes calibrate the system so that the crew can hear anyone trying to contact them. After Thebes leaves, Sully stays to listen. She does not mistake the possibility of a signal for an existing connection; there is still no one on the other end. But knowing that she has done what she can changes her relation to the silence. The repaired system is an invitation sent outward, and the effort gives her a measure of purpose even before anyone answers.

Calling and Separation

Sully’s commitment to the mission complicates loneliness rather than canceling it. During the repair spacewalk, she remembers the announcement of the search for Aether’s crew, the later offer of a place on the mission, and the strain her decision placed on her family. She had not been the one to tell Lucy that she would be away for more than two years; Jack delivered the news instead. Looking back from the spacecraft, Sully considers whether she would choose the same course again and concludes that, even knowing how events would unfold, she would not have done anything differently. The passage holds sacrifice and conviction together: she recognizes the loneliness of her position while accepting that she followed her calling.

That acceptance does not make the personal cost abstract. Sully remembers returning to a home that no longer feels like hers and seeing Lucy settled into a family arrangement from which Sully feels excluded. The distance is not merely measured in travel or time away; it is also the painful recognition that others have continued caring for Lucy in her absence. The contrast between Sully’s chosen mission and the life that went on without her makes connection something she values but cannot simply reclaim by wanting it.

Radio Contact and Unresolved Connection

When Aether approaches the International Space Station, Sully resumes contact with the Arctic survivor she had previously reached by radio. He speaks about the dark days and frozen landscape, including polar bear tracks he has found. Sully recognizes in his attention to the tracks a loneliness like her own: even minimal evidence of another presence can matter when direct companionship is absent. Their exchange is not an encounter in person, and Sully cannot confirm what he looks like. He remains, to her, a voice at a distance.

The conversation ends before Sully is ready for it to end. She remains in the communications pod after the signal breaks, listening instead to the ship and to the faint sounds of her crewmates. She imagines going to find him, but concludes that the Soyuz pod must land in a region where the crew has a better chance of survival. A landing on Ellesmere Island would be too dangerous, and the attempt might fail to find him at all. The decision preserves the distinction between wanting contact and being able to reach someone safely: she cannot turn recognition into rescue.

The survivor’s fate remains unknown to Sully, who believes he will die alone. That uncertainty gives the episode its particular force. Radio contact briefly narrows the distance between two isolated people, but it cannot promise an enduring link or change the conditions that separate them. Across Devi’s remembered family, the crew’s shared mourning, Sully’s distant attachment to Lucy, and the voice from the Arctic, connection is repeatedly made real through attention and effort. Its limits remain just as real.
