The European Space Agency (ESA) proposes to construct a standard lunar time to increase the synchronization and convenience of space missions..
With dozens of lunar missions planned around the world over the next decade, the European Space Agency (ESA) is proposing establish a new time zone on the Moon To facilitate the process of exchanging information, Smithsonian reported on February 28.

Currently, the Lunar mission Use the time zone of the supporting country. But this method is not precise and makes spacecraft from different countries inconsistent. The ESA announced an effort to standardize time on the Moon on February 27, but the idea was first proposed at a meeting in the Netherlands late last year.
Establishing standard lunar time not only facilitates communication, but also helps astronauts orient themselves. Space agencies are considering installing it global navigation satellite system (GNSS) on the Moon about year 2030. The system will work similarly to GPS on Earth, using satellites carrying atomic clocks to calculate location.
However, experts have not yet determined how to calculate lunar time. On the Moon, clocks move faster than on Earth because gravity has the ability to bend time. Specifically, the Moon’s clock will increase by approximately 56 microseconds every 24 hours. This level also varies depending on where the clock is placed on the Moon, according to the ESA.
Experts could synchronize lunar time with Coordinated Universal Time (UTC) or build a completely new system, separate from Earth’s time system. As on Earth, they can divide the Moon into several time zones. This would make sense if humans established permanent communities on the Moon, according to Jörg Hahn, ESA’s Moonlight Lunar Navigation and Communications project engineer. Experts also discuss which organization or unit should establish and maintain the time of the new moon.
“It will be a big challenge. But once we establish a timekeeping system for the Moon, we can continue to do the same for other planets.”said Bernhard Hufenbach, member of the Moonlight management team.
