China built an artificial moon to test its low-gravity environments

Chinese scientists have built an "artificial moon" research center that enables them to simulate low-gravity environments such as the moon using magnetic force. Scheduled for official commissioning in 2022, the facility will use powerful magnetic fields inside a 60-centimeter-diameter vacuum chamber to neutralize gravity. To develop the technology, scientists were inspired by an experiment that used a magnet to suspend a frog. Was. artificial moon, however, has other uses. According to Li Ruilin, a geotechnical engineer at China University of Mining and Technology, the chamber, which is filled with rocks, dust and rock cover to simulate the moon's surface, is the first of its kind in the world and can withstand such low gravity conditions. When you want to save.

Scientists plan to use the facility to test technology in long-term low-gravity environments before sending it to the moon, where gravity is one-sixth the Earth. This artificial moon allows them to eliminate any costly technical complexity and identify specific structures that remain on the surface of the moon. In this way, the possibility of the stability of a human habitat on the moon can be examined at a much lower cost.

However, if an external magnetic field is applied to those atoms, everything changes: the electrons change their motion and their magnetic field to oppose the field Applied, produce. If the outer magnet is strong enough, the magnetic repulsion between it and the atomic field will be strong enough to overcome gravity and suspend the object in the air, whether it is an advanced piece of lunar technology or an amphibian. Additional experiments in this lunar simulator chamber will be used to assist China's lunar exploration program called Chang'e. The program includes Changhai 4, which landed on the moon in 2019, and Changhai 5, which collected rock samples from the moon in 2020. China has also announced that it will set up a research station in Antarctica by 2029.
