Spacewalk. Astronaut Bruce McCandless in his manned maneouvering unit (MMU) during an extravehicular activity (EVA, spacewalk) above the Earth on 7th February 1984. This occurred 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 Kennedy Space Center, USA, on 3rd February 1984 and landed back at Kennedy on 12th February 1984.
