Summary
FLOCK 4Y-25, also known as Flock 4y-25, is a CubeSat (3U) satellite manufactured by PLAN and launched on January 3, 2023, from the Cape Canaveral Space Force Station using Falcon 9 launch vehicle. It has dimensions of 0.3 meters in length and span, with a diameter of 0.1 meter. The satellite weighs 5.7 kilograms both at launch and dry mass, indicating it carries no additional fuel or consumables for extended missions. Its primary payload is the Dove 24b2 imaging system capable of capturing images using PS0, PS1, or PS2 equipment. FLOCK 4Y-25's mission is technology demonstration, powered by solar cells and batteries, with a projected lifetime ranging from about one year in an ISS orbit to two to three years in a Sun-Synchronous Orbit (SSO). The satellite has no motor except for some variants (#Flock-3p') which may have FEEP motors. Its shape consists of a box-like structure with two pan extensions. The ownership and operational control are under PLAN, the same entity responsible for its manufacturing.
