Shuttle-Mir Background - Mir Onboard Operations

Mission Control Center (Moscow) generally uplinked a flight plan to the crew, each day. This plan covered a single day, five days in the future and it gave a high degree of crew autonomy in the actual scheduling of activities.

A "crew day" started at eight a.m., Moscow time, and extended to eleven p.m., allowing nine hours off for personal time and sleep. Usually, Mir crews were worked five days per week and took two days off. During the days off, crew members were required only to do light housekeeping and perform their physical exercises, which took about two hours each day.

In actuality, Mir crews often worked much longer than the eight-to-eleven, five-days-a-week regime, sometimes becoming very fatigued.
