Summary
The FLOCK 4S-39 satellite, also known as Flock 4s-39, is a CubeSat (3U) technology satellite manufactured by PLAN and owned by the same entity. It was launched on January 24, 2021, from AFETR Launch Complex 40 using a Falcon 9 launch vehicle. The satellite has dimensions of 0.3 meters in length, 0.1 meters in diameter, and spans 0.3 meters. Its dry mass is 5.7 kilograms, which is also its launch mass. Equipped with a PS0, PS1 or PS2 imaging payload (Dove 2458), it relies on solar cells and batteries for power. The expected lifetime of the satellite varies from approximately one year in an ISS orbit to two to three years in sun-synchronous orbit (SSO). Its shape is described as box-shaped with two panels.
