What do scientists mean by saying not to "build a house" on the back of the moon?

With the successful landing of Chang 'e IV on the back of the moon, China came from behind in this space race to explore the moon, and probably surpassed the United States.

Considering that the back of the moon is older, which is more important for studying the history of the moon and the solar system, and that the moon itself can shield all kinds of radio signals from the earth and provide a rare pure land for low-frequency radio astronomical observation, Italian scientists have recently launched an initiative to protect the unique environment on the back of the moon from various non-scientific uses (such as real estate, tourism and military).

As early as 20 10, Claudio Maccone, an expert from the International Academy of Astronautics (IAA), submitted a protection plan for the back of the moon to the United Nations Committee on the Peaceful Uses of Outer Space.

Mike Kang En pointed out that at present, all the space powers are focusing on the moon, and the new space race is in full swing. Only the United Nations has enough authority to protect the unique "no radiation noise" environment on the back of the moon, but the situation is becoming more and more urgent, and "settlers" from the earth are likely to arrive first before the United Nations passes the relevant protection proposal.

In this study, published in the Journal of Astronautics in June, 20 19, Maccone proposed to set up a circular protected area (PAC) with a diameter of 1, 130 miles (1 820 kilometers) on the back of the moon.

In addition, a "Moon Village" can be set up in the area near the South Pole of the Moon with the longitude 180 south of PAC, which is convenient for obtaining water ice nearby. This proposal was also approved by the Director General of the European Space Agency, JanW? Rner's support.

Maccone believes that the Daedalus crater on the back of the moon is an ideal place to deploy radio telescopes or phased array detectors in the future, and it is the least polluted area of the moon by radio, which can be used for many studies such as astronomy, astrobiology and SETI.

So why don't scientists build houses on the back of the moon? Now you know what this means!
