Space-Based Solar Power (SBSP)<\/a>, a technology Japan is currently pioneering to ensure a sustainable future, has the ability to provide a world where solar energy never fades, even when the sun sets or clouds gather. At the heart of this journey is the OHISAMA project<\/a>, named after a lovely Japanese term for \u2018the sun\u2019 that conveys warmth and gratitude.Commissioned by the Ministry of Economy, Trade and Industry (METI) Japan, this mission plans to launch a small satellite into orbit by 2026. Unlike land-based solar farms, this revolving power station will capture high-intensity sunlight in space and beam it back to Earth using precise microwave technology. If successful, OHISAMA will provide the first real-world proof that we can harvest clean, \u2018always-on\u2019 energy from space.<\/p>\n

What is the OHISAMA mission
<\/h2>\n<\/p>\n

The OHISAMA project is a government-led initiative coordinated by the Japan Aerospace Exploration Agency (JAXA) and Japan Space Systems. The mission will use a small satellite weighing approximately 180 kilograms which is roughly the size of a household washing machine. Scheduled for launch in 2026, the satellite will be placed into a low earth orbit at the height of about 400 to 450 kilometres from the ground.Once in position, the satellite will unfold a solar panel measuring approximately two square metres to capture sunlight. While the power output is roughly one kilowatt, which is just enough to run a small appliance, the mission\u2019s true purpose is to serve as a high-tech \u2018proof of concept.\u2019 It aims to demonstrate that solar energy can be collected in the harsh environment of space, and beam down accurately to a specific target on our planet in the form of microwaves.<\/p>\n

How can we beam down solar energy from satellite
<\/h2>\n<\/p>\n

The process begins with the satellite\u2019s solar panels, which convert sunlight into direct current (DC) electricity. This electricity is then converted into a 5.8 GHz microwave beam. These microwaves are a reliable power supply with the ability to pass through Earth’s atmosphere with very little loss of energy, unlike the laser beams which can be blocked by heavy rain or thick clouds.On the ground, a specialized receiving station in Suwa, Nagano Prefecture (Japan) will be waiting to catch the beam. This station has 13 antenna arrays spread across 600 square metres, designed to capture the microwave signal and convert it back into usable electricity. These ground receivers are often called \u2018rectennas\u2019 (rectifying antennas).<\/p>\n
