Time zone for the moon 10.03.2023

On July 21, 1969, Neil Armstrong took the first life-changing step on the moon. This happened just when the standard universal time on our planet reached 2:56 am. But what time was it for the Nile? There is no answer to this question yet, but given the plans for settling the moon, this may change. At a recent meeting in the Netherlands, representatives of space organizations from around the world agreed that we need to introduce a proper lunar time zone - an internationally recognized common lunar standard time that all future missions can easily use for communication and navigation. A recent meeting in the Netherlands was organized and hosted by ESA researchers, but the discussion was collaborative.

The goal is to create a mutually agreed upon framework called LunaNet that will provide a common interface for all future monthly missions, optimizing their networking, navigation, detection, information and communication. Timing will be key for future operations.

In the next few years, several robotic landers from various space organizations and private companies will be sent to the moon. In addition, ESA, NASA, the Japan Aerospace Exploration Agency (JAXA) and the Canadian Space Agency (CSA) are working together to build a lunar orbital station called Gateway from which future missions can launch.

"These missions will not only be on or around the moon at the same time, but will often interact with each other - potentially transmitting messages to each other, conducting joint observations or conducting rendezvous operations," the European Space Agency said in a press release.

Historically, every mission that went to the Moon used atomic clocks on Earth to track their progress, synchronizing their time in space with time on Earth. To do this, it was necessary to "get in touch" and ask people on Earth what time it is, and also take into account the time required to make this call. Ordinary old clocks aboard a spacecraft simply won't do the job. The forces of gravity and velocity on the Moon are different, which means that they affect time differently than the forces acting on our planet.

In practice, this means that if a lunar astronaut takes a clock from Earth with him, they will go faster than usual by tens of microseconds per day. How much faster depends on whether the astronaut is in orbit or standing on the Moon itself. Under these conditions, it will be difficult to establish a stable time reference specifically for the Moon, but it can be more accurate and faster than synchronization with Earth time. This is what scientists are now discussing. Should we observe Earth time or switch to the lunar time zone?

The latter scenario would require a working lunar time system and a common coordinate system on the Moon's surface, similar to the one we use on Earth to track orbiting satellites. This may take more energy and effort, but the result may be a much more accurate system that can then be applied to other planets.
