Cosmos 1001

Cosmos 1001 was a redesigned Soviet Soyuz T spacecraft that failed an uncrewed test in 1978. The spacecraft was the upgraded Soyuz for Salyut-6 and Salyut-7. This is Soyuz's 45th flight. The Soyuz is a Soviet crewed spaceship, developed to made manned lunar missions. This version called 7K will fly 4 times on the giant launcher N1, and several tens of times on Proton to fly over the Moon, which will be successful during the mission Zond 4. Soyuz will become the first spacecraft to transport living beings to the Moon during the flight of Zond 5, with two turtles. Subsequently, it is adapted to low orbit and will fly on the Soyuz launcher to serve the Salyut and Mir stations and the ISS.
