Chinese scientists propose magnetic launcher on moon to send resources to earth – Reports

BEIJING, August 18 (Sputnik) – Chinese scientists proposed building a magnetic launcher on the Moon, which could become an cost-effective way to deliver resources mined on the lunar surface to Earth, and, in addition, part of the Russian-Chinese lunar station project, the South China Morning Post newspaper reported on Sunday.

According to the publication, scientists from the Shanghai Institute of Satellite Engineering suggest that the magnetic levitation installation will work on the same principle as the hammer throw in athletics, but the rotation at increasing speed will be carried out before a cargo capsule is sent to Earth.

Scientists are convinced that, due to the unique environmental conditions on the Moon, such as high vacuum and low gravity, payloads can be sent twice a day, and the cost of such transportation will be about 10% of the cost of existing methods.

“The system’s technical readiness is relatively high. Since it consumes only electricity and does not require any propellant, it will be relatively small in scale and straightforward to implement,” the scientists said in their paper.

They also noted that the main task will be the extraction of helium-3 to help solve the problem of the energy crisis on Earth. The project, in their opinion, will also contribute to the development of space mining technologies, heavy launch vehicles and artificial intelligence.

The proposed launch system will use a 50-meter-long rotating arm and a high-temperature superconducting engine to launch capsules with mined resources. Ten minutes after launch, the rotation speed of the arm will reach the second cosmic velocity of the Moon of 2.4 kilometers per second and about one-sixth of the second cosmic velocity of Earth — and put it on the correct trajectory for returning to Earth.

The system is designed to last at least 20 years, but it will weigh about 80 tonnes, so before it can be delivered to the Moon, it will be necessary to wait for the start of operation of the Chinese super-heavy launch vehicle, the publication said.

The team working on the project suggested that it could be part of a proposed joint Russian-Chinese project to build a research station at the south pole of the Moon by 2035.

The intergovernmental Russian-Chinese agreement on the joint creation of the International Scientific Lunar Station (ISLS) was signed on November 25, 2022. Russian President Vladimir Putin signed a law ratifying the agreement on June 12, 2024, and it entered into force on July 18. The document was published on July 25. It indicates that the station will be created in three phases and will receive modules both on the surface of the Earth’s natural satellite and in its orbit. During the third phase, it is planned not only to study and develop the Moon, but also to assist other countries in landing on the Moon. The implementation dates for each of the phases are not yet mentioned.
