A description is given of the manner in which A. Leonov performed his walk in space. The spacesuit worn by Leonov is presented as a complex engineering scheme involving the color of the suit, the light filters protecting the astronaut from solar radiation, the self-contained oxygen-supply system, ventilation, its own power supply network to meet communications requirements, and the physiological control system. The spacesuit is made from rubber, fabrics, metal, synthetic materials, and consists of a metal helmet with transparent visor, an airtight suit, and special shoes and gloves. An umbilical cord is connected to the spacesuit, providing it with oxygen for breathing and air for ventilation of the suit. This extremely durable and elastic cable also contains flexible wires for transmitting telemetering data and maintaining communications with the spacecrafts commander and with ground stations. During the tests, physiologists decided to remove the nitrogen from the astronauts body before he left the air lock, thus making it possible to lower barometric pressure in the spacesuit to 0.4 atm without endangering the life of its occupant. It was found that the breathing of pure oxygen for over 1 hour literally washes all nitrogen from the tissues. The astronauts collaborated with designers and engineers in solving many of the complex design problems of the Voskhod-2 spacecraft.
