Alexei Leonov, first space walk, 1965

First space walk. Soviet cosmonaut Alexei Leonov (born 1934), outside the Voskhod 2 spacecraft in a spacesuit on 18 March 1965, while orbiting the Earth (in the background). This was the world's first extravehicular activity (EVA), or space walk. Voskhod 2 had launched earlier that day, and Leonov exited the spacecraft at 08:30 UTC. He remained outside for 10 minutes, before trying to re-enter. Because his suit had ballooned while outside, he had to let some of his air out before he could successfully re-enter. Cameras mounted on the airlock were meant to record the space walk, but most had to be abandoned due to the problems with Leonov's spacesuit. The CCCP on Leonov's helmet refers to the USSR

Komarov before Soyuz 1 launch, 1967

Komarov before Soyuz 1 launch, speaking at the launch site in Kazakhstan, on 23 April 1967. Soviet cosmonaut Vladimir Komarov (1927-1967) was killed during this mission. He launched later the same day, but the spacecraft soon began to spin out of control during its orbits. Komarov's wife was brought to the control centre to say farewell. After 18 orbits, Komarov attempted to perform a re-entry and safe landing on 24 April 1967. The parachutes failed to deploy properly, and he was killed on impact, becoming the first person to die during a space flight. It was later reported that the Soviets had rushed the launch of Soyuz 1 before it was fully ready, timing it to coincide with political celebrations for Lenin's birthday

Manned maneuvring unit space walk, 1984

Manned maneuvring unit space walk, 1984. Astronaut Bruce McCandless floats free above the Earth in his manned manoeuvring unit (MMU) on 7th February 1984, during the 10th space shuttle flight (mission 41B). McCandless, who helped design the MMU, was the first person to fly it, thus becoming the first "human satellite" in orbit around the Earth. The MMU is propelled by small nitrogen thrusters which are controlled by the astronaut's hands. Because no umbilical cord attaches the astronaut to the spacecraft, it gives much greater mobility than was available to earlier spacewalkers. Mission 41B was launched from the Kennedy Space Center (KSC) on 3rd February 1984, and landed back at KSC on 12th February
