Cosmos 133



Cosmos 133 was a Soviet Soyuz test satellite launched from the Baikonur cosmodrome aboard a Soyuz rocket. It was the first test flight of the Soyuz 7K-OK earth orbit spacecraft. It was a planned "all up" test with a second Soyuz to be launched the following day and automatically dock with Cosmos 133. However, its attitude control system malfunctioned, resulting in rapid consumption of orientation fuel, leaving it spinning at 2 rpm. After heroic 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 November 30, 1966 at 10:21 GMT.
