Korea Aerospace Research Institute (KARI) Beat National Aeronautics and Space Administration (NASA) Record

January 31, 2024

Many nations are making investments in the research and development of space solar power.

The Korea Aerospace Research Institute (KARI) has successfully tested wireless power transmission across a distance of 1.81 kilometres in space, surpassing the 1.5 kilometres set by the U.S. National Aeronautics and Space Administration (NASA) as the greatest distance to date.

Alongside the Korea Electrotechnology Research Institute, the test used an aerostat with a light-emitting diode (LED) for power receiving and an antenna.

The Korea Deep Space Antenna (KDSA) in Yeoju, Gyeonggi Province, used transmission technology to send electricity during the test. The aerostat's receiving antenna received two kilowatts of electrical power from the aeronautical antenna.

Lead researcher Park Deok-jong stated that the LED lit up as a symbol of the power created when the antenna turned the signal into direct current.
