Astronauts describe persistent 'observer' sensation after 6 month missions | Hacker News

Astronauts report a lasting observer-like detachment after about six months in space.

Commenters compare the feeling to dissociation, depersonalization, VR side effects, and long submarine deployments.

The discussion highlights how isolation and rigid routines may alter perception and identity in space.

The issue matters for astronaut mental health and future long-duration missions, including trips to Mars.
