Space Explainer: The ISS & Life in Orbit

Crew members typically rotate every 5-6 months, arriving and departing on Soyuz or Crew Dragon spacecraft. Their days are tightly scheduled around scientific experiments in microgravity, station maintenance, and roughly 2.5 hours of mandatory daily exercise to counteract the bone and muscle loss that comes from living without gravity.
