Summary
The satellite FLOCK 4Y-5, also known as Flock 4y-5, is a CubeSat (3U) technology demonstration satellite manufactured by PLAN and owned by the same entity. It was launched on January 3, 2023, from AFETR Launch Complex 40 aboard 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 kg, which is the same as its launch mass. It is equipped with PS0, PS1 or PS2 imaging payloads (Dove 24b4) for technology demonstration purposes. Power is supplied by solar cells and batteries. The expected lifetime of FLOCK 4Y-5 is approximately one year in an ISS orbit and two to three years in a Sun-Synchronous Orbit (SSO).

The Pentagon's Mystery Spaceplane Takes Off
On April 22, 2010, an Atlas V lifted off from Cape Canaveral carrying a reusable robotic spaceplane so secret that the Air Force would not even confirm its mission duration.
