Olesya Ilyukhina

Name

• Canonical: Olesya Ilyukhina
• Aliases: "Ilyukhina" in formal references; "Olesya" between crew

Role in the story

Russian aerospace engineer assigned to the Hail Mary as one of the three astronauts on the one-way mission. Aboard the ship she is the boisterous, irreverent counterweight to Yáo's discipline and Grace's anxious rigor — she swears, drinks, jokes, and breaks crew tension by force of personality. She does not survive the medical-coma transit; Grace finds her body in the medical bay in Chapter 1, and she returns in flashbacks (most pointedly the Ch. 21 suicide-pact briefing).

Personality / energy

Loud. Warm. Profane. Fearless about her own death because she has already accepted it. She drinks vodka she shouldn't drink, sings songs she shouldn't sing, and treats the impending suicide of her own crew with a dark humor that makes the situation tolerable for the others. Her energy is life, generously and loudly distributed, set against a job that requires her death.

Physical description

• Russian woman, late thirties to early forties at recruitment
• Strong, sturdy build — broad-shouldered, athletic but not slim
• Pale skin, weathered slightly by years of hard work
• Dark blonde to light brown hair, kept short or pulled back for practicality
• Round face, ready smile, prominent laugh lines — a face that has spent a lot of time amused
• Eyes: render as light blue or gray-blue

In her corpse appearances (Ch. 1, 6, etc.) her body is dried, leathery, almost mummified in zero-g — strapped into the medical bay cradle. Her hair is still recognizable; her face is not — the skin has shrunk in. It is a hard, sad image.

Outfit / clothing notes

• Living, training era: dark blue mission-prep coveralls, often unzipped halfway and tied at the waist; black t-shirt or tank underneath; mag-boots
• Living, briefing-room era (Ch. 21 suicide-pact flashback): civilian clothes worn easily — a dark sweater, plain pants — she looked, by choice, like a civilian when off-duty
• Corpse: the same flight coverall as Grace, now drawn loose around a smaller frame; strapped into the medical cradle; a single ID patch on the shoulder

Visual motifs (recurring objects, color associations, symbols)

• A flask, a bottle, or a smuggled drink — visual shorthand for "the one who refused to be solemn about her death"
• A laugh line caught mid-laugh in flashback
• A mag-boot stance — feet planted wide on the deck
• The medical-cradle straps holding a still, dried figure (corpse appearances)

Magic / power signature

None. Human aerospace engineer.

Chapter appearances

• Ch. 1, 6: corpse, medical bay
• Ch. 21: alive, suicide-pact briefing flashback
• Other flashbacks scattered through the first half (training, suit-up, launch)

Confidence

Medium — physical description is sparse in summaries; personality is consistently described as loud, profane, joyful. We lock a Russian-coded sturdy-built late-30s woman with practical hair and warm eyes, with the explicit note that the book itself is light on specific facial detail.
