Summary

Story summary

Researchers from the Purple Mountain Observatory in Nanjing developed software for lunar timekeeping to support navigation and landings as lunar missions increase.
Clocks on the Moon run faster than on Earth due to weaker gravity, creating discrepancies.
The model synchronizes lunar and Earth time and remains precise to tens of nanoseconds over 1,000 years.
Harvard astronomer Jonathan McDowell says accurate lunar timekeeping is increasingly needed for navigation systems.
