The White House on April 2 directed NASA to establish a unified standard of time for the moon and other celestial bodies, as the United States aims to set international norms in space amid a growing lunar race among nations and private companies.
The head of the White House Office of Science and Technology Policy (OSTP), according to a memo seen by Reuters, instructed the space agency to work with other parts of the U.S. Government to devise a plan by the end of 2026 for setting what it called a Coordinated Lunar Time (LTC).
The differing gravitational force, and potentially other factors, on the moon and on other celestial bodies change how time unfolds relative to how it is perceived on Earth. Among other things, the LTC would provide a time-keeping benchmark for lunar spacecraft and satellites that require extreme precision for their missions.
