Summary
The FLOCK 4S-48 satellite, also known as Flock 4s-48, is a CubeSat (3U) launched on January 24, 2021, from Cape Canaveral Air Force Station's Launch Complex 40 using the Falcon 9 launch vehicle. It was manufactured by PLAN and has dimensions of 0.3 meters in length and diameter with a span of 0.3 meters. The satellite weighs 5.7 kilograms both dry and at launch and is equipped with PS0, PS1 or PS2 imaging payload under the Dove 2465 mission. Its power comes from solar cells and batteries. It operates primarily for technology purposes in either an ISS orbit (~1 year) or SSO (2-3 years). The satellite's shape is described as a box with two panels and was stabilized by February 8, 2021.
