CTOnews.com, March 2, according to CCTV News, with the accelerated pace of lunar exploration, people increasingly feel the need for a unified lunar time. The European Space Agency said recently that space agencies have begun to discuss how to set the time of the moon and are looking for a suitable plan.

According to USA Today, the European Space Agency issued a statement this week that at a meeting held at the European Center for Space Research and Technology in November last year, participants agreed that it was "important and urgent" to establish a "universal reference time" for the moon. Pietro Giordano, a navigation system engineer at the European Space Agency, said in a statement that countries are currently cooperating to this end.

There is no unified answer to the question "what time is it on the moon?" The existing lunar exploration activities are based on the time of the launching country. When the lunar spacecraft is in contact with the earth, it uses the deep space communication antenna to ensure that the chronometer it carries is synchronized with the time of the launching country.

The European Space Agency believes that this way of timing the moon is "not reliable". The agency expects dozens of lunar missions over the next 10 years, including the return of astronauts to the moon. These activities will take place in lunar orbit or surface and may involve exchanges, interaction and even cooperation between different countries or commercial institutions. If there is a recognized lunar standard time, it will bring a lot of convenience to all parties to explore the moon.

At present, the relevant international cooperation is only discussing whether it is necessary to set up an agency specifically responsible for setting the time of the moon. From a technical point of view, it is very difficult to establish a universal reference time for the moon.

According to CTOnews.com, clocks go differently on the earth and on the moon, which is 56 microseconds slower on the earth than on the moon every day. Moreover, clocks and clocks work differently in different positions (such as tracks or surfaces). It is also a big problem to set the requirements that can be used in the life and work of astronauts, such as being practical, easy to use and in line with human biological rhythms. Bernard Huffenbach, a member of the European Space Agency's relevant task force, said that setting a practical lunar time is extremely challenging, considering that a day and night is equivalent to 29.5 earth days in the equatorial region of the moon. But if we succeed in building a viable time system for the moon, it will be easier for humans to build time systems for other planets in the future, he said.

The International Space Station has faced similar problems in its design and construction. At present, the space station uses coordinated Universal time (UTC), which is based on the international atomic time seconds to accurately calculate the time difference of the countries participating in the space station mission, including the United States, Russia, Japan and European countries.
