Multiple teams in China are currently focused on technologies needed for building and running a space-based solar power facility, which will allow the sun's energy to be captured nonstop, something that isn't possible from Earth, said Hou Xinbin, a senior researcher at the.

Space-Based Solar Power (SBSP or SSP), the concept of gathering solar power in space using solar power satellites (SPS) to send it back to Earth, may sound like science fiction, but it is getting closer to reality. China plans to build a 1km-wide solar array in the geostationary orbit about. That vision is now one step closer to reality as China pushes forward with its ambitious space-based solar power project. If successful, this could revolutionize. When the United States, Japan, or the European Space Agency talk about orbital power stations, it tends to stay in the research-paper realm. When China starts funding hardware and building test facilities, the world pays attention. stronautics said that China's planned space solar power plant is expected to have a capacity of one te, Dongfanghong, weighed only 173 kilograms, China's space station, which was completed in 2022, weighs 100 tons. It is moving solar power into space.
