China Launches Open-Source Lunar Timekeeper Aiming for Century-Long Nanosecond Precision
China’s Purple Mountain Observatory released LTE440, an open-source software system to track and synchronize lunar time with Earth for long-duration missions, boasting nanosecond-level accuracy over a thousand years. The tool, available on GitHub with a Harvard ADS manual, could aid future precision landings and navigation on the Moon, while NASA pursues its own Coordinated Lunar Time amid broader U.S.-China tech tensions.
