 NASA to Establish Unified Standard Time for Moon

In a groundbreaking move, the White House has tasked NASA with establishing a unified standard of time for the moon and other celestial bodies. This directive comes as the United States seeks to assert leadership in space and set international norms amidst a burgeoning lunar race involving nations and private entities.

The head of the White House Office of Science and Technology Policy (OSTP) has instructed NASA, according to a memo seen by Reuters, to collaborate with other branches of the U.S. government to develop a plan for what is termed as Coordinated Lunar Time (LTC) by the end of 2026. LTC aims to address the discrepancies in timekeeping caused by varying gravitational forces and other factors on the moon and other celestial bodies, which affect how time is experienced relative to Earth.

Kevin Coggins, NASA's space communications and navigation chief, emphasized the necessity of LTC, explaining that clocks on Earth would tick at a different rate on the moon due to these factors. The establishment of LTC would provide a crucial time-keeping benchmark for lunar spacecraft and satellites, ensuring precision in their missions.

Under the ambitious Artemis program, NASA is gearing up for astronaut missions to the moon and the establishment of a scientific lunar base, laying the groundwork for future expeditions to Mars. However, without a unified lunar time standard, ensuring secure data transfers between spacecraft and synchronized communications between Earth, lunar satellites, bases, and astronauts would pose significant challenges, warned an OSTP official.

The adoption of LTC is envisioned to streamline operations, enhance security, and facilitate coordination as commercial activities expand to the moon. It is deemed essential for managing the logistics of lunar commerce and ensuring the reliability of transactions.

Moreover, as countries like China, Japan, and India express their lunar ambitions, the OSTP memo highlights the importance of U.S. leadership in defining a suitable time standard, emphasizing that it will benefit all spacefaring nations. Implementation of Coordinated Lunar Time will necessitate international agreements, involving existing standards bodies and signatories of the Artemis Accords.

With the potential deployment of atomic clocks on the lunar surface, the stage is set for a new era of synchronized timekeeping in space, marking a significant milestone in humanity's exploration beyond Earth's bounds.
