In collaboration with Switzerland's Astrostrom company, the European Space Agency (ESA) is envisioning a groundbreaking project called the Greater Earth Lunar Power Station (GE⊕-LPS).
ESA tells us in a blog post that this study aims to construct solar power satellites primarily using lunar resources, including moon-manufactured solar cells, to provide renewable energy for surface activities and potential future crewed bases.
Utilizing Lunar Resources
Taking inspiration from the elegance of a butterfly, the GE⊕-LPS features innovative V-shaped solar panels with integrated antennas arranged in a helix configuration that stretches over a square kilometer.
These advanced solar panels are based on iron pyrite monograin-layer solar cells produced right on the moon. This ingenious approach not only reduces the cost of manufacturing but also utilizes the abundance of lunar resources, making the entire system self-sufficient.
Power Generation and Location
The lunar power station, located at an Earth-moon Lagrange point around 61,350 km from the lunar surface, is designed to provide continuous power of 23 megawatts for lunar surface operations.
The station will also serve as a pivotal gateway between Earth and Moon operations, facilitating potential tourist activities and providing artificial gravity for adaptive health purposes.
This unique combination of clean energy generation and space exploration could lay the foundation for future space settlements in cislunar space.
What's the Catch?
While the concept of Space-Based Solar Power may seem futuristic, the study emphasizes that it does not require any groundbreaking technological breakthroughs.
Most of the core technologies needed for lunar surface mining, beneficiation, and fabrication are already in use or under development on Earth.
By extrapolating and adapting these technologies to the lunar environment, the production of solar power satellites on the moon becomes economically viable and environmentally friendly.

This lunar power generation system offers numerous other benefits besides addressing Earth's clean energy needs. Launching satellites from the moon significantly reduces the energy required to place them into geostationary Earth orbit compared to satellites launched from Earth itself.
This reduction in velocity change opens doors for developing a cislunar transportation system, mining facilities, processing centers, and manufacturing facilities, effectively creating a two-planet economy.
The success of this project could mark the birth of a spacefaring civilization, propelling humanity further into the cosmos.
What's Next?
The GE⊕-LPS project represents a major step forward in the quest for sustainable energy solutions both on Earth and beyond.
ESA's SOLARIS R&D initiative plays a crucial role in confirming the feasibility of Space-Based Solar Power for terrestrial clean energy needs.
If proven successful, this visionary project could pave the way for large-scale, cost-competitive, and environmentally friendly solar power satellite production.
With ongoing advancements in space exploration and renewable energy, the possibilities for a brighter, cleaner future are within our reach.
