To colonize space, China is building an experimental satellite that simulates the conditions of gravity

Inspired by experiments that used magnets to fly a frog into space, China built a research facility that simulates a low-gravity environment on the moon.

Chinese researchers are working on the development of a facility in able to simulate the gravity of the lunar surface, according to the South China Morning Post, which was seen by Al Arabiya.net.

The satellite will be one camera vacuum which uses a strong magnetic field to recreate a low gravity environment.

Construction is expected within a few months, said lead scientist working on the project, Lee Ruelin. It will allow you to control gravity long enough to search.

Ruelin, of China University of Mining and Technology, predicts the facility will take lunar simulation to a new level.

He explained that the big difference between it and the previous simulations, which depended on gravity masking, was that they were temporary operations that only took a few seconds, while the effect could last in the new experiment structure as long as desired.

The structure consists of one camera vacuum containing a small moon with a diameter of 60 square centimeters, while it contains rocks and light dust such as those on the moon – the force of gravity on it is about one sixth of the force of gravity on Earth – in part because it is supported by a magnetic field.

Lee said the idea came from the experiments of Russian-born physicist Andrei Gem flying a frog with a magnet, for which he was awarded a comic prize called Nobel LG, in 2000. However, Jim’s research at the University of Manchester in England, in the field of graphene, led him to obtain the Nobel Prize in Physics in 2010.

Jim was pleased that his purely didactic experiments on magnetic levitation had led to applications in space exploration.

This Chinese move comes in light of its efforts to take the lead in the new international space race with the United States. This includes the lunar exploration program, as well as its recent missions to land a rover on the other side of the moon in 2019 and in 2020 to bring rock samples back to Earth for the first time. in 44 years old.

China aims to land astronauts on the moon by 2030 and establish a joint research base on the moon with Russia.

For its part, Chinese space authorities said last month that construction of the research station could begin as soon as 2027 – and years ahead of schedule – amid concerns over US-led moves to establish rules for the future lunar activities. NASA also plans to send astronauts to the moon by 2024 as part of the Artemis program.

Li said the Suzhou facility should play an important role in the future China’s missions to the moon, including building infrastructure on the moon.

The lab will allow scientists to test equipment – and possibly prevent costly miscalculations – in simulating the extreme lunar environment, where rocks and dust can behave. in very different way than on Earth. This is due to the absence of an atmosphere on the Moon, the temperature can change rapidly and drastically and, in in the case of low gravity, the soil particles are more tightly bound together.

This comes after China failed to return all of the expected rock samples, due to drilling problems and unexpected resistance from the ground. It is a repetition of the previous missions carried out by the Soviet Union and the United States.

Experiments with a smaller simulation prototype indicated that the resistance to craters on the Moon could be much higher than predicted by theoretical models.

Simulating the harsh lunar environment on Earth was no easy task – the magnetic force required is so strong that it can tear components such as superconducting wires. Add to this several metal components that are needed in the camera empty and not working properly near a strong magnet.

Li claimed that the team has come up with a number of technical innovations to overcome these challenges, including simulating moon dust that can float more easily in a magnetic field and the replacement of steel with aluminum in some key components.

He said the Chinese facility will be open to researchers from around the world.
