Japan's space agency JAXA and Mitsubishi Electric have developed a new Earth observation satellite, Daichi-3. The developers say the satellite can detect objects as small as 80 centimeters on the Earth's surface. They expect Daichi-3 to become one of the key tools for creating maps for disaster management. The satellite is 5 meters high, 16.5 meters wide, and weighs about 3 tons. The onboard sensor has a resolution three times higher than the first Daichi, which was retired in 2011. Daichi-3 is also capable of sending up to 1.8 gigabytes of data per second, double the previous speed. JAXA plans to launch the satellite on Japan's next-generation H3 rocket by March 2023. A Mitsubishi Electric official says he hopes the satellite will be useful for preventing and mitigating disasters.
