What is the typical duration, in hours, of the scheduled work portion of an ISS astronaut's duty day in UTC?
Answer
About 10.5 hours.
A typical workday structure for an astronaut serving aboard the International Space Station is anchored to the UTC clock. The standard duty day is structured to run from approximately 6:00 UTC until 19:30 UTC. This timeframe results in about 10.5 hours allocated specifically for scheduled work activities. These tasks encompass a comprehensive range of responsibilities, including conducting necessary science experiments, performing station maintenance, mandatory exercise routines, and communicating directly with the ground teams supporting the mission. This structured period concludes before the designated personal time leading up to lights out, which is generally around 21:30 UTC.
