As nations race to establish permanent lunar bases, a new challenge has emerged—timekeeping on the moon. The United States and international partners are working to address the fact that time passes slightly faster on the moon than on Earth. This seemingly small difference is significant enough to require a new system for measuring time. NASA and its partners are now developing a unique lunar timescale to ensure accuracy for future missions.

The Challenge of Time on the Moon
The lunar environment is not just different in terms of its landscape, but also in how time flows. On the moon, time moves approximately 56 microseconds faster per day than it does on Earth. While this might seem insignificant at first, over time it could cause serious discrepancies. NASA is collaborating with international agencies to create an entirely new timescale, designed specifically for the moon, rather than simply adopting a lunar time zone.
Precision Timing for Future Missions
NASA’s Artemis program, which aims to return humans to the moon by 2026, makes the need for precise lunar time essential. Astronauts will rely on accurate timekeeping for navigation, communication, and conducting scientific experiments. This precision is not just about keeping track of time, but also about ensuring smooth coordination between lunar missions and Earth-based operations. Scientists are now determining how to synchronize lunar time with Earth’s time to facilitate seamless communication and data transfer.
Relativity and Lunar Time
Albert Einstein’s theory of relativity is a key factor in the development of lunar time. According to Einstein, gravity affects the passage of time, meaning the farther one is from a massive object, the faster time moves. This principle applies to the moon, where gravity is weaker than on Earth. As a result, the creation of a reliable time system must consider these physical principles to ensure an accurate and consistent lunar timescale.
Global Collaboration on Lunar Time
NASA, alongside partners like the European Space Agency (ESA), is working to establish a standardized lunar time system that all space-faring nations can use. One idea is to install atomic clocks on the moon, similar to those used on Earth, to ensure precise timekeeping. These clocks could be placed in satellites or lunar habitats to provide a reliable framework for all future missions. The development of lunar time will not only be crucial for moon exploration, but may also serve as a model for timekeeping on Mars and beyond.
The creation of a lunar timescale is an essential step toward ensuring the success of future missions. As space exploration expands, solving these timekeeping challenges will become increasingly important for the advancement of human activity beyond Earth.
