Summary
The FLOCK 4Q-21 satellite, also known as Flock 4q-21, is a CubeSat (3U) configured spacecraft manufactured by PLAN and owned by the same entity. Launched on November 11, 2023, from AFWTR's SLC4E pad using a Falcon 9 launch vehicle, this satellite has a length of 0.3 meters and a diameter of 0.1 meters with a span also at 0.3 meters. Its dry mass is recorded at 5.7 kg, matching its launch mass. Equipped with PS0, PS1 or PS2 imaging payloads under the Dove 24b7 configuration for technological purposes, it harnesses power from solar cells and batteries. The satellite's expected lifetime varies depending on orbit, ranging from about one year in an ISS orbit to two to three years in a sun-synchronous orbit (SSO).

The 300,000 Swerves Keeping Low Earth Orbit From Crashing
Starlink satellites fired their thrusters to dodge a collision roughly 300,000 times in 2025, about 822 times a day. Behind that number is a fragile, half-automated system of warnings, probabilities, and judgment calls that decides which close approaches are worth a maneuver and which are just noise.
