Launched from the Baikonur Cosmodrome aboard the maiden flight of the Soyuz 11A511 s/n U15000-02 launch vehicle.[3] Kosmos 133 was planned "all up" test, to include an automated docking with a second Soyuz spacecraft (Soyuz 7K-OK No.1), which was scheduled for launch the day after Kosmos 133.
Kosmos 133 was operated in a low Earth orbit, on 28 November 1966, it had a perigee of 171.0 km (106.3 mi), an apogee of 223.0 km (138.6 mi), an inclination of 51.9°, and an orbital period of 88.4 minutes.[2]
Problems found during ground testing of the second spacecraft resulted in its launch being delayed, and it was destroyed when its launch vehicle exploded on its launch pad following a scrubbed launch attempt in December 1966. Before this, the attitude control system (ACS) of Kosmos 133 malfunctioned, resulting in rapid consumption of orientation fuel, leaving it spinning at 2 rpm. After large efforts by ground control and 5 attempts at retrofire over two days, the craft was finally coming down for a landing. Due to the inaccuracy of the reentry burn, it was determined that the capsule would land in China. The self-destruct command was given and the satellite exploded 30 November 1966 at 10:21 GMT.[1]
The fireball passed over west Japan and was recorded by photos and a sketch. Kōichirō Tomita identified that it was the Kosmos 133 spacecraft (30 November 1966).[4]
