ISS Time Zone

The International Space Station operates on Coordinated Universal Time (UTC), also known as Greenwich Mean Time (GMT). This ensures consistent scheduling for international crews and ground control centers around the world. Times shown in the chart above are in UTC. The ISS orbits Earth every 90 minutes, experiencing 16 sunrises and sunsets per day, making UTC essential for mission coordination.
