Commander · Day 143 · Transit
Sleep is down, mood is down, sleep schedule is down. Sleep is 5.1 h, below your usual 7.3 h (5.4 baseline widths). Falling about 0.2 h a day over the last 5 days. Affected: head, heart & vessels.
| Region | Worst measure | Weight | Points lost |
|---|---|---|---|
| Head | Sleep | 24% | −62 |
| Heart & vessels | Heart-rate variability | 14% | −1 |
Score = 100 − points lost. 50% follows the single worst region; the rest is a weighted mix. Transit: Radiation (whole body) and isolation (head) are weighted highest.
Heart health
62bpm resting
Heart-rate variability is 54 ms, below your usual 64 ms (1.8 baseline widths). Falling about 2.0 ms a day over the last 5 days.
Sleep 7 h for 2 nights + 1 h shared crew time.
Projected green by Day 146
If nothing changes: not green within 7 days.
With sleep 7 h for 2 nights + 1 h shared crew time: green on Day 146
Haddad's drifting measures are stepped forward day by day. Each hour of sleep above a short night, each hour of shared crew time, extra exercise and extra fluids pull specific measures back by fixed amounts (at most 1 baseline width per day). A grid search tries every combination and keeps the one with the least effort that is green by the day after the plan ends.900 plans were checked. The plan then assumes your usual routine.

Fatigue-error risk
Red alertWhysleep down 2.2 h on 2 or more of the last 3 nights, and reaction time up 22 ms on the reaction test.
Do nowAvoid safety-critical tasks alone today. Use the path back to green and repeat the reaction test tomorrow.
Sleep schedule is drifting
Red alertWhysleep schedule down 12 /100 on 3 or more of the last 4 days: bed and wake times are moving.
Do nowHold a fixed wake time for 3 days and get bright light in the first hour awake.
Standing order from Dr. Nadia Rahme (flight surgeon)
Standing orderWhySleep < 6 h for 2 days in a row.
Do nowTwo short nights in a row. Protect tonight: no duty after 21:00, dim the lights one hour before bed, 7 hours in your bunk. If a third short night follows, tell the commander and message me.
