Long-Duration Spaceflight Isolation & Morale Simulator

A rotating space habitat holds a crew whose individual stress levels evolve in real time under a model built from documented space-psychology findings: adaptation load that grows with isolation and sensory monotony, team-cohesion activities and Earth contact that counteract it, and a genuine morale recovery in the mission's final stretch. Adjust crew size, mission duration, cohesion programming and Earth communication delay — the light pulse crossing to the small Earth model shows exactly how long a message takes to arrive — and watch the crew's colour-coded stress levels, and the group's average morale, trace out the "third-quarter phenomenon" documented in ISS increments and Antarctic winter-over research.
