Zond 6

Zond-6's scientific payload consists of a radiation detector, a micrometeorite detector and a biological container. This is the first time that a machine returning from the Moon achieves a controlled return to the atmosphere. L1 was a Soviet spacecraft launched on Proton, designed in parallel of 7K-L1, which flew on the N-1 launcher. It was conceived to carry out crewed flybys of the Moon, like Apollo 8. This spacecraft sent the first living beings to fly over the Moon, turtles, on board Zond 5. The work made on this spacecraft will be used for the improvement of the Soyuz spacecraft.
