Summary
FLOCK 1-23 (also known as Flock 1-25) is a CubeSat (3U) satellite owned and operated by Planet Labs (PLABS), launched from the Taiyuan Satellite Launch Center (TYMSC) on November 20, 1998. It has dimensions of 0.3 meters in length, 0.1 meters in diameter, and spans 0.3 meters. The satellite weighs 4.25 kilograms both at launch and dry mass. Equipped with a PS0, PS1 or PS2 imaging payload (Dove 0722), it utilizes solar cells and batteries for power generation. Its mission is primarily technological in nature. The satellite's shape is described as box+2 pan configuration, with a reflective surface area (RCS) of 0.0914 square meters. Launched using an Antares 120 launch vehicle from Pad 0A, it was stabilized by February 27, 2014. Its expected lifetime varies between approximately one year in the International Space Station orbit and two to three years in Sun-Synchronous Orbit (SSO).
