China's Shanghai Institute of Satellite Engineering (SAST) has proposed a magnetic launch system designed to transport resources from the Moon back to Earth. This concept, reminiscent of ideas explored in science fiction, aims to utilize magnetic levitation technology to create a cost-effective method for launching payloads, particularly helium-3, which is abundant in lunar regolith. The proposed system would consist of a 50-meter rotating arm powered by solar panels and a nuclear reactor, capable of launching payloads at the Moon's escape velocity of 2.4 km/s. The SAST team estimates that the system could conduct two launches daily at a fraction of the cost of current methods, potentially addressing Earth's energy needs through helium-3, which could power fusion reactors. The project aligns with China's long-term vision for the International Lunar Research Station (ILRS), expected to be completed by 2035. However, the construction of the launch system is contingent upon the development of China's Long March 9 and Long March 10 rockets. The estimated cost for the launch system is around $18.25 billion, with potential revenues from helium-3 mining projected at 100 billion yuan annually. Despite the promise of this technology, significant technical and logistical challenges remain, including the extraction of helium-3 and the stability of the launch system in the harsh lunar environment.
- China proposes a magnetic launch system for transporting lunar resources to Earth.
- The system aims to utilize helium-3 from the Moon to address energy needs on Earth.
- Estimated cost for the launch system is $18.25 billion, with potential high revenues from helium-3 mining.
- The project is part of China's long-term plans for the International Lunar Research Station, expected by 2035.
- Significant technical challenges must be addressed before implementation, including helium-3 extraction and system stability.
