Anything you want to put down, in your own words. It stays on the vehicle and is released entry by entry, never automatically.
Dictation turns speech into text on this device. No audio is kept: a stored voice is a biometric, and this record does not hold one.

Adding the session writes its minutes straight into today's exercise log, so the countermeasure record is what you actually did, not what was scheduled.

▸ What counts
Counts days with every daily item logged and some exercise done. It is never broken by a short night.

HOW THIS SPEAKS TO YOU
Set before launch, changeable any time.
LANGUAGE
DEPTH
A pre-launch session sets the language, the reading level and the personal baselines, and checks that the crewmember can actually use the screen under load. Everything set there can be changed in flight.

EARTH-INDEPENDENCE
WHO DECIDES
The agents recommend. The flight surgeon decides. No agent issues a drug dose or a fluid volume on its own, and every red band pages a human.
Sleep and mood notes stay out of the automatic downlink. They move only when you release them.
GENERATE A REPORT
Builds a written summary for the timeframe below, from the same evaluation the other tabs use. Nothing here is recalculated.
LIVE TELEMETRY · WHAT THE HARDWARE IS SENDING
Raw values as received. Bands come from the same evaluation the crew screen uses.
EVOLUTION · TWO HALVES COMPARED
Each window is split in half and the halves compared. Where a half holds fewer than two readings, no mean is shown, because a mean of one reading is not a mean.
HEALTH OVER TIME
EVERY INDICATOR · LAST 30 DAYS
Everything this vehicle tracks for you, each with its direction. The colour of a line is the band of its latest reading.

HARDWARE AND DATA COMPLETENESS
WHO YOU ARE
Sex is recorded on the crew record because a few reference ranges depend on it. It is a
clinical field and nothing else: it does not decide how you are addressed or which modules
you get.
This changes the drawing, and moves any marker off a limb that is not there. It changes no threshold and no check, it is used for no assessment of you, and it is not shared with anyone.
Lower-limb prostheses are offered because that is the case an agency has certified: in February 2025 the European Space Agency announced a leg amputee medically certified for long-duration station missions
(ESA, Fly! study). Other limb differences are not drawn yet.
Your record
Your record is kept on this device only. Download gives you all of it as one file. Erase removes all of it and cannot be undone.
The body map is drawn from these. It is a schematic carrying your
proportions so a finding sits where it belongs on you, not a likeness and not a measurement of your shape.

HOW THE AGENT BEHAVES
How it speaks to you
Tone changes the wording, never the finding. There is deliberately no setting that makes an urgent thing sound calm.
Set separately, because a mixed crew does not share one language. The assistant can speak Russian while the bubble reads English.
The assistant is a shape, never a face. A synthetic human face giving medical guidance implies a clinician who does not exist, so this one does not pretend to be one. The colour here is the interface accent; the red, amber and blue that carry meaning never change.
SCREEN
No red-tinted night mode is offered. Under red light the red and amber status colours stop being distinguishable, and this screen uses colour to say how urgent something is. The shapes and words still work, but the colour layer would be lost, so the dim option reduces brightness instead of shifting hue.
WHERE THIS VEHICLE IS
This decides which indicators are installed and, with the signal delay and the distance
from help, how urgently anything found has to be acted on.
CREWMEMBER · WHAT YOU CARRY WITH YOU
Set before launch and editable in flight. None of it is diagnosed here, and none of it moves a threshold.

CHALLENGES YOU SET

You choose the subject and the number. The app counts it and says where you are; it never raises the number for you.
MAKE SOMETHING OUT OF YOUR OWN RECORD
Everything here is built from what you actually logged. Nothing is
invented and nothing is generated: the figures in a film are your figures, and the questions in a game come from your own days. Say or type what
it should be about, and the words are matched against your entries and tags.

WHAT IT MAY USE
Entries and feelings are off by default. They are private to the
vehicle, and putting them into something you might share is a release — so it has to be a decision, not a default.
BUILD FROM ONE OF YOUR JOURNEY ENTRIES
Hear an entry read back, then build from that one entry alone. The app reads your
written words aloud; it does not hold a recording of your voice, and never has.
MY GADGETS · HOW EACH ONE ACTUALLY WORKS
Pick an instrument. The diagram comes apart so you can see what each
piece does, and the text below says how to take a reading with it, how to read what comes back, and what makes a reading wrong. Nothing here is
needed to use the system \u2014 it is here because a crewmember who understands the measurement argues with it better than one who does not.
HOW TO READ THIS TOOL
What this is. Research prototype running on synthetic crew data. Not cleared or approved by the FDA, and not for diagnosis or treatment. It is meant to be used under flight-surgeon oversight: it tells you what to raise, not what you have.
Four things are worth knowing before anything else.
It judges against three frames, not one. Every reading is compared with this crewmember before flight, with their own rolling norm in the current context, and with a published standard. The same heart rate can be normal in one frame and an alert in another, which is why the frame is always named.
It says when it does not know. Where no verified threshold exists, none is applied. Body mass and suit CO₂ are reported as trends with no band at all, rather than given an invented limit.
Two colour systems, deliberately. Red, amber and green say how far a reading sits from its band. NOW, WITHIN HOURS, TODAY and NOTE IT say how soon you must move. Nothing in the urgency scale is green, because green means in range and an action point never is.
Colour is never alone. Every level also carries a word and a distinct shape, so the screen still works for a colour-blind crewmember, in monochrome print, and under coloured cabin lighting.
NASA STANDARD MEASURES · WHAT THIS BUILD DRAWS ON
Five areas this build draws on.
NASA collects a defined set of measures across every mission so crew data can be compared between flights. Most of it needs a laboratory, a scanner or a centrifuge. Only the areas SYNAPSE takes at least one measurement in are listed.
WHY THERE ARE NO AGE OR SEX BANDS
No threshold in this build changes with a crewmember’s age or sex. That is a choice, not an
omission. Almost everything here is judged against that person’s own preflight baseline and
their own adapted range in flight, and a personal baseline already carries whatever their age,
sex, build and fitness contribute — more faithfully than a population band fitted to people
who are not them. Published limits are applied only where the limit is itself stated for
everyone, as the career dose limit in NASA-STD-3001 [V1 4030] is.
The cost of this choice is stated plainly: where a reference range in the literature genuinely
does differ by age or sex, this build does not model that difference, and the band it shows is
the general adult one. Where no verified threshold exists at all, no band is applied and the
reading is reported as a trend against that crewmember alone.
EVERY THRESHOLD, AND WHERE IT COMES FROM
NASAa value stated in a NASA standard or brief
Clinicala published terrestrial reference range
Peer-revieweda published study
Operationala triage split chosen by Team 3S, not from any standard
Noneno verified threshold exists, so none is applied
Two different questions, two different colour channels.
Red, amber and green say how far a reading sits from its band.
NOWWITHIN HOURSTODAYNOTE IT
say how soon you have to move. Nothing in the urgency scale is green, because green on this screen means in range, and an action point never is. Each level also differs in fill and carries its own word, so the meaning survives colour-blindness and red cabin lighting.
