NASA To Create Time Standard For the Moon

artmancc writes: The White House has directed NASA and other federal agencies to get to work on a plan to implement precision timekeeping and dissemination on the moon and elsewhere in space. Reuters cited a memo from the head of the White House Office of Science and Technology Policy (OSTP) that "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 name of the proposed time standard is similar to the terrestrial time standard known as Coordinated Universal Time (UTC). "OSTP chief Arati Prabhakar's memo said that for a person on the moon, an Earth-based clock would appear to lose on average 58.7 microseconds per Earth-day and come with other periodic variations that would further drift moon time from Earth time," Reuters reported. An unidentified OSTP official said the lunar time standard is needed for secure and synchronized communication between astronauts, satellites orbiting the moon, and Earth.
