Celebrates 50 Years of Spacewalking

NASA Celebrates 50 Years of Spacewalking - In this Feb. 7, 1984 photograph taken by his fellow crewmembers aboard the Earth-orbiting Space Shuttle Challenger on the STS-41B mission, NASA astronaut Bruce McCandless II approaches his maximum distance from the vehicle. McCandless became the first astronaut to maneuver about in space untethered, during this first "field" tryout of a nitrogen-propelled, hand-controlled backpack device called the Manned Maneuvering Unit (MMU). - Image Credit: NASA
