Summary
IGS R-8 is a reconnaissance satellite (OBJECT_ID: 2024-176A) launched on September 26, 2024, from the Tanegashima Space Center in Japan using the H-IIA 202 launch vehicle. The spacecraft has dimensions of 3 meters in length and 4 meters in diameter with a span of 16.5 meters due to its deployable solar panels. It weighs approximately 1500 kg at launch, reducing to a dry mass of 1000 kg. IGS R-8 is part of Japan's Information Gathering Satellite program managed by the Cabinet Satellite Intelligence Center (CSICE) and manufactured by Mitsubishi Electric Corporation (MELCO). Equipped with an advanced Synthetic Aperture Radar (SAR) system for high-resolution Earth observation, it operates in radar bands and provides sub-meter resolution imaging. The satellite is powered by solar arrays and employs a three-axis stabilization system to ensure precision pointing capabilities, enabling it to conduct reconnaissance and environmental monitoring missions over its five-year designed mission duration.
