Flight Description

The world's first group space flight . At the same time as Vostok-4, Vostok-3 was in space, piloted by Andriyan Nikolaev . Due to the great accuracy in putting both ships into orbit, the parameters of their orbits practically coincided, the maximum approach of the ships was about 6.5 km. In flight, the astronauts visually observed each other's ships. One of the tasks of the joint flight of the two ships was a military experiment under the program of creating a satellite interceptor, while Vostok-4 played the role of an interceptor, while the launch of Vostok-3 a little earlier was the goal. ^[one]

From an interview with Pavel Popovich:

The next day, I started. It entered orbit, immediately saw its ship. Between us was four kilometers.

Andrey began: “Golden eagle, Golden eagle, I am the Falcon. How do you hear me? ”

I shout to him: “Hello, Andrey! I not only hear you, I see you! You fly to my right like a little moon. ”

Physiological Characteristics

Laboratory studies of the urine of cosmonauts Popovich and Nikolaev showed an increased calcium content in the astronauts' body, which was explained by the absence of loads on the human muscular system in zero gravity comparable to atmospheric pressure on Earth, which also led to demineralization of bone tissues. In addition, this circumstance was explained by the peculiarities of the new spacesuits supporting the pressure inside, equivalent to ^1⁄2 atm ^[2] .
