Japan is going to test sending electricity from space through Space Solar Power technology in 2026. The satellite named Ohisama will send solar energy to the earth in the form of microwaves from a height of 450 kilometers. This mission is the first step towards bringing about a revolutionary change in the field of stable, reliable and clean energy.
Space Solar Power Mission: Japan is going to launch a demonstration satellite named Ohisama in 2026, which will convert solar energy generated in space into electricity by sending it directly to Earth. This mission was conducted by Japan Aerospace Exploration Agency’s Usuda Deep Space Center and Space One Co. Will be done with the cooperation of. Its aim is to develop stable and reliable energy sources and open new possibilities for future commercial use and space missions.
Space-Based Solar Power
Space-Based Solar Power (SBSP) aims to place large solar panels in Earth orbit. These panels will generate electricity from sunlight and send it to the ground through microwave or laser. The receiving station will then supply this energy to the grid.
This system is not affected by clouds, rain or day-night changes, making it a stable and reliable energy source. This will help in reducing future energy crisis and impact on climate.
Ohisama mission and technical details
The Ohisama satellite weighs 180 kilograms and will send 720 watts of power into the microwave from an altitude of 450 kilometers. Its power panel is 70 cm × 2 m. Japan Aerospace Exploration Agency’s Usuda Deep Space Center has receiving antennas, which will test this energy by lighting LEDs. This satellite is Space One Co. Will be launched from Kairos 5 rocket.
In future plans, huge solar arrays can be installed at an altitude of 36,000 kilometers, which can generate 1 GW of electricity and meet 10 percent of Tokyo’s annual electricity needs.
Japan’s global leading position
America, China and Europe are also working on this technology, but Japan has been doing research in this field since the 1980s. Its expertise in microwave transmission and beam control keeps it ahead in the global race. If successful, it could enable commercial use in the 2040s and energy supplies for future lunar missions.
