NIST Proposes Lunar Timekeeping System as Moon Time Moves 58.7 Microseconds Faster

Aug 15, 2024, 07:10 AM

Researchers and international organizations are working on developing a precise timekeeping system for the Moon. The National Institute of Standards and Technology (NIST) has proposed a new lunar timekeeping system to address the challenge of clocks on the Moon ticking faster than on Earth by 56 microseconds per day. This proposal includes the use of atomic clocks in lunar orbit, which could pave the way for a lunar GPS system. The International Astronomical Union has also joined calls for a lunar clock, emphasizing the need for a consistent timekeeping standard as the Moon becomes a focus for future exploration. This initiative is crucial for establishing a long-term Moon base and ensuring constant communication with Earth. The time on the Moon moves 58.7 microseconds faster each day due to lower gravity.
