Earth observation satellite "Daichi 4" unveiled, plans for launch next year Kanagawa. The Earth observation satellite was developed by JAXA (Japan Aerospace Exploration Agency) and Mitsubishi Electric at a cost of approximately 32 billion yen.
It weighs approximately 3 tons and is very tall when equipped with solar panels. It is 10 meters long and 20 meters wide. Since images can be created based on the strength and weakness of radio waves emitted by satellites as they reflect on the ground, it can be observed at a high resolution of approximately 3 meters even at night.
