Space-walk. View of US astronaut Bruce McCandless (1911-1968) using a Manned Manoeuvring Unit (MMU) during an extra-vehicular activity (EVA, spacewalk) in orbit over the Earth. 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 Kennedy Space Center, USA, on 3rd February 1984 and landed back at Kennedy on 12th February 1984.
