Summary
COSMOS 1644 (also known as Kosmos-1644) is a reconnaissance satellite, specifically designed for photographic film return missions, launched on April 3, 1985, by the Soviet Union from the Tyuratam Space Center's LC31 launch pad using a Soyuz-U launch vehicle. The spacecraft measures 6 meters in length and has a diameter of 2.2 meters with a span of 6 meters. It is based on the Zenit bus configuration and carries the Oblik No. 12L payload, weighing 2655 kg at launch. Its propulsion system includes motors such as the 11D82M and S5.120 (maneuver module). The satellite's power source consists of batteries, and it has a spherical shape with a deployable cone structure for its mission purposes. The satellite was operated by GUKOS and manufactured by TSSKB.
