NASA outlines lunar timekeeping, navigation, and communications roadmap
A NASA white paper describes how lunar communications, navigation, timing, and surface observation capabilities could grow alongside the agency's Moon Base. It proposes Coordinated Lunar Time to keep lunar operations synchronized as mission activity increases. The phased effort begins with testing through 2028, moves to infrastructure deployment in 2029–2032, and later aims for a long-term human presence at multiple sites near the lunar south pole.
NASA's August white paper outlines how lunar infrastructure could expand with its Moon Base. It proposes Coordinated Lunar Time, computed by averaging readings from multiple lunar atomic clocks, with each clock weighted, much as UTC is set on Earth. Relativity changes time on the lunar surface and in orbit, so LTC would correct for that and could later scale to other solar system locations.
Development proceeds in stages: testing through 2028, infrastructure deployment from 2029 to 2032, then long-term human presence. Centralized Lunar Surface Sites near the south pole would grow from one to more than five, all between 84°S and 90°S.
A shared lunar time and navigation framework could affect astronauts, mission controllers, spacecraft operators, and commercial or international partners working near the Moon. By synchronizing clocks and positioning, it may reduce coordination risks as traffic grows. It could also shape technical standards for future lunar services, making interoperability easier, though adoption and governance questions may arise. Broader society might see benefits through safer missions and accelerated scientific return, but near-term effects would likely remain concentrated among space agencies and industry.
