Chinese scientists plan to build a colossal 0.6-mile-wide solar power station in space, designed to beam energy back to Earth, likened to an orbital "Three Gorges Dam."

The station will transmit energy via microwaves from geostationary orbit, offering uninterrupted power, unlike ground-based solar stations hindered by weather and atmosphere.

To construct the massive array, China’s Long March-9 reusable rockets will loft components into orbit, each with a lift capacity of 150 tons.

China isn’t alone. The U.S., Japan’s JAXA, and the European Space Agency are exploring similar space-based solar power systems, with Japan launching a test satellite this year.

Dubbed the "Three Gorges Dam in space," this project mirrors the scale of Earth’s largest hydropower station, which generates 100 billion kilowatt-hours annually.
According to NASA, solar intensity in space is ten times stronger than on Earth, making orbital stations a more efficient solution to global energy demands.

The Long March-9 rockets are pivotal not just for solar arrays but also for China’s lunar research base plans, aiming for completion by 2035.
If successful, space-based solar power could redefine global energy supply, providing a clean, continuous source of electricity while minimizing Earth’s resource exploitation.
