1. study the origin and evolution of the moon: there have always been volcanoes on the surface of the earth and "rock convection" below the surface, so the earth has been changing all the time, so it is impossible to understand what the earth looked like at first. If we have a detailed understanding of the moon through the observation of the "Moon Goddess", we can solve the mystery of the time and process of the formation of the moon. By studying the origin of the moon, scientists can find clues about how the earth and the early solar system formed.

2. Get information about the surface environment of the moon: the earth has an atmosphere, but there is no atmosphere on the moon. In this way, sunlight can hit the surface of the moon. "Moon Goddess" will orbit the moon for about a year to study the influence of the sun on the moon. The observation results are very important for future moon landing activities such as establishing a base on the surface of the moon.

3. Radio wave research in lunar orbit: The Goddess of the Moon carries some instruments, and the observation target is not limited to the moon. It is most suitable for observing electromagnetic waves in space, because there are no artificial electromagnetic waves emitted by TV and mobile phones. In addition, the "Moon Goddess" will also study the influence of the sun on the earth by observing the aurora from the moon at the same time. By observing space and the earth from the moon, scientists can obtain observation data that is difficult to obtain from the earth.
