APOD from 2009-09-27
To Fly Free in Space
Astronaut Bruce McCandless II ventured 100 meters from the Challenger using an MMU in 1984, marking the first untethered spacewalk. The nitrogen-jet-powered MMU, weightless in orbit but heavy on Earth, has been used for satellite work and was later replaced by the SAFER unit.
