At 10 o’clock Moscow time, the spacecraft “Vostok-2” with cosmonauts Pavel Belyayev and Alexei Leonov successfully launched from the Baikonur Cosmodrome.

At 11:34:51 Leonov went into outer space. He was connected to the spacecraft only by a 5.35-meter-long tether, which included a steel cable and electrical wires for transmitting medical observation and technical measurement data to the ship, as well as for telephone communication with the ship’s commander Belyayev.

Leonov spent 12 minutes and 9 seconds in space.

All this time, a comfortable temperature was maintained in the spacesuit, and its outer surface heated up in the sun to +60°C and cooled down in the shade to -100°C.
