Astronauts on the International Space Station use Coordinated Universal Time (UTC) to maintain a consistent schedule. This standard time helps synchronize activities between mission control centers across different time zones on Earth. They operate on a 24-hour schedule with allocated times for work, exercise, and rest to ensure smooth coordination and efficient mission progress.

FAQs & Answers

  1. Why do astronauts use Coordinated Universal Time? Astronauts use UTC to synchronize their schedules with mission control centers around the world, helping to coordinate activities effectively.
  2. How do astronauts keep track of time in space? Astronauts follow a 24-hour schedule based on UTC, allowing them to allocate specific times for work, exercise, and rest.
  3. What is the significance of time management on the ISS? Effective time management on the ISS is crucial for mission success, ensuring all activities are performed on schedule and efficiently.
  4. What challenges do astronauts face with time zones? Since astronauts operate in a microgravity environment with no natural day-night cycle, they rely on UTC to manage schedules and interactions with Earth.
