The source of power for the station is the sun - light is converted into electricity through the solar panels. Station provides atmospheric pressure, oxygen level and water. The highest priority system on station is the atmospheric system.

The ISS has been inhabited since November 2000. Three members of crew lives at station for half of a year. Than they are replaced. The crew is keeping up the station. All station crews are named "Expedition N", where N is number increased after each expedition. There was 15 crews since 1998. Day and night cycling is controled automatically.
