Summary
FLOCK 4Y-21, also known as Flock 4y-21, is a CubeSat (3U) satellite manufactured by PLAN and launched on January 3, 2023, from AFETR Launch Pad LC40 using the Falcon 9 launch vehicle. This technology demonstration satellite has dimensions of 0.3 meters in length, 0.1 meters in diameter, and spans 0.3 meters. It has a dry mass of 5.7 kg and was equipped with a PS0, PS1 or PS2 imaging payload named Dove 24ba at launch. The satellite’s power system consists of solar cells and batteries, and it operates in either an ISS orbit for approximately one year or in Sun-Synchronous Orbit (SSO) for 2-3 years. It has no motor except for a few variants (#Flock-3p') that use FEEP propulsion systems.
