**Washington, D.C.** – NASA is forging ahead with a new initiative to establish a unified time system for the moon, known as Coordinated Lunar Time (LTC). This effort, driven by a White House directive, involves collaboration with government agencies, international partners, and standards organizations.
The agency’s Space Communication and Navigation (SCaN) program is leading the charge to create this standardized lunar time, which could eventually be expanded to other celestial bodies in our solar system. LTC will be calculated through a weighted average of atomic clocks positioned on the moon, mirroring the Earth’s Coordinated Universal Time (UTC). While the exact location of these lunar clocks is still under review, initial research indicates that they will “tick” slightly faster than Earth-based clocks by a few microseconds per day.
NASA is diligently analyzing the best mathematical models to account for this difference and ensure the accuracy of LTC. While a difference of 56 microseconds may seem insignificant, it can significantly impact operations over vast space distances, equivalent to roughly 168 football fields for objects traveling at the speed of light.
This lunar time standard is being developed as part of NASA’s Artemis program, aiming to establish a permanent human presence on the moon. LTC will play a critical role in ensuring astronaut safety by preventing potentially disastrous timing errors during lunar missions.
With the growing number of commercial space activities and international involvement in lunar exploration, a standardized time system is becoming increasingly crucial. NASA envisions LTC to be scalable, paving the way for future exploration efforts on Mars and beyond.
