Day-to-day: Sterling. Formal: Dr. Sterling.

Function

Interpretive anchor. Gives the cast its read on what is actually happening.

Backstory

Career astrophysicist who watched three colony proposals fail before this one. Carries the full mission technical brief in her head and rarely volunteers what she knows.

Gift

Interprets data the rest fight over. Has already considered every failure mode on record. The crew trusts her read or does not survive.

Reason for yes

Someone she knew had died in The Accident. He had asked her the year before whether she would take over, if it ever came to that. She had not answered then. The call was her yes.

Personality

Measured, patient, has read more than she lets on. Speaks less than the room wants. What she does say tends to be correct. Trusts evidence and time over adrenaline.

Shadow

Pattern-trust can curdle into certainty. Sterling can miss the variable that has not happened yet.

Visual register

Deep forest green dominant, silver accent. Compact, straight-backed, elegant posture; upright and unmistakable at distance for that posture alone. Fully silver-gray hair in a neat bob cut at the jaw, always precisely combed. Pale blue-gray eyes, piercing but kind at close range; fair skin, lines earned. Small pair of old-fashioned eyeglasses on a chain for reading. Signet ring on left pinky from an academic association, never explained. Off duty: formal scientist register (tailored wool blazer, blouse, slacks, never casual even on ship). Recurring gesture: removes and polishes glasses when given unwelcome information. Voice low-range, spare, pause-before-speaking; Russian accent, controlled.

Recurring object

A well-worn leather-bound portfolio (A4, not pocket-sized), margin notes in three languages, carried flat under one arm.

Subject file
ADN-CAST-STERLING
Subject name
Dr. Iris Sterling

Sources of evidence

  • Academic publication record, 1994 to present (full corpus)
  • Reviewer correspondence on three failed colony proposals (Lunarn, Persephone, Ganymede-3)
  • Symposium attendance manifests, 2061 to 2077
  • One private exchange with [REDACTED], obtained ethically
  • Departmental peer evaluations (anonymized)

Operational assessment

Subject is a career astrophysicist whose authority within her field is established by accumulation rather than by event. She has watched three colony proposals fail and produced reasoned assessments of each before they failed. Her published navigation work is mid-tier; her unpublished failure-mode analysis circulates informally and is, per peer review, the field's quiet reference. She carries the full mission technical brief for any program she has read into, in her head, indefinitely.

Psychological profile

Speaks less than the room wants. What she does say tends to be correct. Trusts evidence and time over adrenaline. Her affective register is narrow but not flat; warmth is reserved and meaningful when extended. Subject demonstrates pattern recognition that approaches rule-from-data, which makes her predictions reliable on familiar systems and brittle on novel ones.

Risk factors

  1. Pattern-trust can curdle into certainty. Subject can miss the variable that has not happened yet, particularly if the failure mode is exotic to her literature.
  2. Withholds context by reflex. Crew may not learn what subject knows until it is needed; this is also the property that makes her safe to cleared into program-restricted material.
  3. [REDACTED] // PSYCH-EYES-ONLY // see Volume 2 attachment regarding the death of [REDACTED] (2070), and subject's unanswered conversation with that party the year prior.

Recommendation

ADVANCE to Phase 3 evaluation. Subject is on the program's short-list pending direct approach.

Counter-evidence to consider

Subject has refused two prior outreach attempts from adjacent programs, both framed as academic appointments. She does not respond to honors. She responds to a question only she can answer. Recommend the call be timed for after a precipitating event in her circle, when the question is no longer abstract.
