Sleep, activity & wellbeing
Follow a fictional astronaut across three demo days. ARCHeR studies activity, sleep and wellbeing using actigraphy and surveys.
Synthetic records inspired by ARCHeR. These are not Artemis crew measurements. ZENIT’s ring does not measure sleep.
Start with context
- Sleep
- 7.5 h Synthetic sleep diary
- Activity
- 30 min Synthetic activity sensor
- Attention
- As usual Synthetic self-report

What we observe
The diary, activity record and self-report describe different parts of the same day.
What it could mean
Together they give a clearer picture than a pulse reading alone. One day is not an established personal baseline.
What we still need to know
We do not know sleep quality, workload or the astronaut’s longer-term pattern.
Only this synthetic step and your practice choices are sent. Your mission records are not included.
