The designation Kosmos (Russian: Космос meaning Cosmos) is a generic name given to a large number of Soviet, and subsequently Russian, satellites, the first of which was launched in 1962. Satellites given Kosmos designations include military spacecraft, failed probes to the Moon and the planets, prototypes for crewed spacecraft, and scientific spacecraft. This is a list of satellites with Kosmos designations between 751 and 1000.
Kosmos 777 was the second spacecraft of the Cosmos 699-type to experience a fragmentation. There may have been two fragmentation events on the day it first broke apart. It created dozens of pieces of debris that could not be tracked.[1]
This was the third spacecraft of the Kosmos 699-type to break apart. It had been naturally decaying for 6 months prior to breaking apart. Much of the debris reentered before being officially cataloged.[1]
Test of 14 meter long module with maneuvering engine . Objective-to increase the size of space stations.[2]
2 February 1978
Baikonur launch. Orbit 214 x 278 km. Inclination 52 degrees. Weight-possibly 20 tonnes. A later test flight Kosmos 1267 docked with Salyut 6 and was called the Star Module.[3]
Baikonur launch. Orbit 150 x 358 km. Inclination 65 degrees. Weight-possibly 4 tonnes. Identified a Republic of South Africa nuclear device that looked like it was about to be exploded in the upper atmosphere.[6]
Baikonur launch. Orbit 251 x 265 km. Inclination 65 degrees. Weight-possibly 3,500 kg. First failure of a nuclear-powered radar ocean surveillance satellite to maneuver to storage orbit.[8]Nuclear reactor failed to eject, spacecraft reentered over Canada
Plesetsk launch. Orbit 964 x 1,010 km. Inclination 83 degrees. Weight-possibly 700 kg. First satellite acknowledged as part of Navsat System.[10] Kosmos 1000 shape was a cylinder with a dome at each end (this was probably the standard small Kosmos satellite), all enclosed in a drum shaped solar panel, length and diameter about 2 meters.[11] Ship locations were believed to be precision computed using the Doppler Effect.[12]
* — satellite was destroyed in orbit rather than decaying and burning up in the Earth's atmosphere
