China may be on the verge of a breakthrough in its lunar exploration plans, with researchers assessing the viability of using laser wireless power transmission (LWPT) to supply spacecraft on the moon.
The concept involves transmitting power wirelessly from orbiting satellites to surface receivers using laser beams, converting light into electricity. This technology could provide a solution to one of the biggest challenges facing China’s lunar exploration ambitions: powering spacecraft during the long, dark nights on the moon.
The researchers recommend developing key technologies and conducting on-orbit testing. The lunar surface is exposed to extreme temperatures and lacks sunlight for 14-day periods, making it difficult for traditional solar power to provide energy.
LWPT could also support operations in permanently shadowed craters, where water-ice is believed to exist, providing a potential source of propellant or oxygen for astronauts.
While the technology still faces challenges such as efficiency and transmission ranges, China’s lunar exploration plans could benefit from its development. The International Lunar Research Station (ILRS), scheduled for construction in the 2030s, will require reliable energy supply solutions.
Developing LWPT systems could provide a level of leadership in the field of sustainable lunar exploration and help overcome key challenges to this ambitious project.
