In a significant move highlighting the increasing human activity on the lunar surface and in space, the White House revealed that it has tasked NASA with developing a synchronized time standard known as Coordinated Lunar Time (CLT), which will be instrumental for missions on the Moon and across other celestial bodies. This decision comes amidst heightened interests in space exploration both by governmental and private entities.
The OSTP within the White House has mandated NASA to design this celestial time standard by the end of the fiscal year 2026 with the intention of setting a benchmark for international space endeavors. Steve Welby from OSTP emphasized the importance of establishing consistent timekeeping in space for improved safety, navigation precision, and communication.
The unique idea behind CLT is to synchronize lunar timekeeping with Coordinated Universal Time (UTC), which is currently the cornerstone for time regulation here on Earth. The unification is touted as a measure to strengthen operations in the dynamic and essential cislunar space, the sector lying between the Earth and the Moon.
The plan details four primary characteristics that the new standard will embody: it should be traceable back to UTC, offer sufficient accuracy for navigational and scientific missions, remain robust against any loss of contact with Earth, and be scalable to function beyond just the cislunar space.
The specific technical manner of implementing lunar timekeeping was not extensively outlined, but OSTP hinted at possibly integrating methodologies analogous to those utilized on Earth— suggesting an ensemble of atomic clocks on the Moon may be the path forward.
The impetus for this initiative is further supported by the United States’ scheduled re-entry to the Moon with a crewed mission in 2026, marking the first human landing since Apollo 17 touched down in 1972.

FAQ Section
- What is Coordinated Lunar Time (CLT)?
CLT refers to the time standard that NASA is set to develop for use on the Moon, which will align with Coordinated Universal Time (UTC) used on Earth. - Why is a lunar time standard necessary?
As outer space missions increase in frequency and complexity, having a consistent time system is crucial for coordinating operations, enhancing navigation precision, ensuring safety, and facilitating communications. - Who directed NASA to create the lunar time standard?
The White House Office of Science and Technology Policy (OSTP) has directed NASA to establish the lunar time standard. - What are the features of the new time standard?
The new lunar time standard should be traceable to UTC, accurate for precise navigation and scientific requirements, durable in case of Earth communication loss, and capable of adapting to environments beyond cislunar space. - When is the United States planning to return to the Moon?
The United States has planned a crewed lunar landing for 2026, which would be the first since the Apollo 17 mission in 1972.
Conclusion
The endeavor to establish a standardized lunar time system reflects the growing realization of space as the next frontier for human exploration and presence. NASA’s development of Coordinated Lunar Time, under the guidance of the White House OSTP, signifies a pivotal step towards the establishment of a universally recognized timekeeping system that reaches beyond our planet. Such advancements not only pave the way for effective mission synchronization but also set the stage for future space-related activities and the expansion of human capabilities beyond Earth. Integrating atomic timekeeping inspired by Earth’s standards onto the lunar surface can potentially usher in a new era of interplanetary synchronization and universal time coordination in the cosmos.
