Kosmos 772 (Russian: Космос 772 meaning Cosmos 772) was an uncrewed military Soyuz 7K-S test. It was an unsuccessful mission as only one transmitter worked. Only the 166 MHz frequency transmitter operated, all of the other normal Soyuz wavelengths transmitters failed. [1] [2] The experience from these flights were used in the development of the successor program Soyuz spacecraft the Soyuz 7K-ST.[3] [4] [5] [6] [7] [8]
