Mitsubishi Electric Corp. recently unveiled its latest satellite, Daichi-4, designed to monitor the Earth's surface using state-of-the-art radar systems to identify abnormal changes that could signal potential disasters. The satellite's purpose revolves around disaster prevention and enhancing the understanding of regions affected by calamities.
During the media presentation in Kamakura, Kanagawa Prefecture, Katsuya Sakai, the deputy head of Mitsubishi Electric's Space Systems division, expressed aspirations for Daichi-4 to play a pivotal role in establishing a secure and comfortable society. The development of this satellite was a long process that spanned over eight years, initiated after an order from the Japan Aerospace Exploration Agency, showcasing the commitment and dedication put into its creation.
Daichi-4, weighing approximately 3 tons and extending up to 20 meters in width with deployed solar panels and equipment, is slated for launch aboard the H-3 rocket in fiscal 2024. Its groundbreaking technology allows for observations four times wider than its predecessor, Daichi-2, significantly enhancing the data collection capabilities for disaster monitoring and response. This upgraded satellite promises more frequent and precise assessments of various environmental changes, ranging from volcanic activities to ground subsidence and disaster aftermath evaluations.
