January 28, 2019 - Bruce on the Loose

Bruce on the Loose  Floating in space with a freedom never before experienced, astronaut Bruce McCandless put NASA’s new Manned Maneuvering Unit (MMU) through its paces during the ambitious STS-41B mission, which was launched 35 years ago this week. McCandless’s two-hour solo jaunt, during which he ventured over 90 meters (300 ft) from the shuttle Challenger, was the first time a spacewalking astronaut traveled without a safety tether. The MMU was maneuvered with a set of nitrogen thrusters that McCandless operated with joysticks located at the end of the arm rests. Astronaut Robert Stewart also spent nearly an hour testing the MMU. During the eight-day mission, Challenger’s crew of five also deployed the Palapa-B2 and Westar-VI communications satellites.
