China Launches World's First Lunar Time Software
13 Jan
Summary
- China's researchers developed the first lunar timekeeping software, LTE440.
- The software synchronizes lunar clocks with Earth time, accounting for gravity.
- It ensures accurate navigation and communication for future lunar missions.

Researchers from China's Purple Mountain Observatory have developed LTE440, the first software designed to synchronize clocks with the Moon. This innovative tool addresses the time discrepancies caused by the Moon's weaker gravity, which results in clocks gaining 58 microseconds daily compared to Earth.
The software accounts for the Moon's motion and gravitational effects, automating complex calculations to ensure precise timekeeping for future lunar missions. This advancement is crucial as NASA prepares for Artemis missions, with Artemis 3 scheduled for 2028, and China aims to land astronauts by 2030.
The development of a standardized lunar time is a global endeavor, with the White House tasking NASA and Congress advancing the Celestial Time Standardization Act. China's publicly available software offers a significant contribution to establishing a universal lunar clock for international and commercial space partners.
