Flock-1 is a CubeSat satellite constellation launched on 9 January 2014. The satellite is built in a CubeSat bus, and each constellation consists of 28 satellites. All instruments are powered by solar cells mounted on the spacecraft body, along with triple-folded wings, providing approximately 20 watts at maximal power.


Flock-1 constellation was launched from Mid-Atlantic Regional Spaceport Launch Pad 0, Wallops Island, on 9 January 2014 by an Antares 120 rocket. The satellites were deployed from the International Space Station (ISS) from 11 February 2014 to 28 February 2014.[1]

Another Flock start in January 2015 on a Falcon 9 launch vehicle.


The satellite is intended for commercial Earth observation service. For this purpose, each satellite is equipped with a camera capable of 3 to 5 m (9.8 to 16.4 ft) ground resolution. Details of intended service by individual satellites were never released publicly and are largely unknown.
