Summary
KORSAT-2, also known as ADD-425-2, is an Earth observation and reconnaissance satellite launched on December 21, 2024, from the Air Force Western Test Range (AFWTR) using a Falcon 9 launch vehicle. The spacecraft measures 2.9 meters in length with a diameter of 1.9 meters and a span of 6 meters when its solar arrays are deployed. It has a dry mass of 750 kilograms and was launched with a total mass of 800 kilograms. KORSAT-2 is equipped with a Synthetic Aperture Radar (SAR) payload featuring a specialized 5-meter antenna composed of 24 petals that deploy to form a parabolic dish. The satellite's power system includes four fixed solar arrays and batteries, and it uses three-axis stabilization through reaction wheels and magnetorquers for precise orientation control. It is designed to operate in orbit for five years as part of the 425 Project SAR constellation and belongs to the Defense Acquisition Program Administration (DAPA). The satellite's shape is hexagonal with three panels, and its color is silver due to an aluminum-clad exterior. KORSAT-2 is manufactured by Korea Aerospace Industries (KAI) and is related to other satellites in the series such as KORSAT-1, KORSAT-3, and KORSAT-4.
