Spacewalk Without A Tether

Published June 19, 2016
Science fiction? In 1984, Bruce McCandless made the first untethered spacewalk, as far as 100 m (109 yd) away from the Space Shuttle.
The device, a jet pack for space called the Manned Maneuvering Unit (MMU), was only used a few times before it was deemed unnecessarily risky. It was followed by a smaller version - the Simplified Aid for EVA Rescue (SAFER) - which an astronaut always wears today if performing a spacewalk outside the International Space Station (ISS). It should only be used in emergencies, something which has not happened yet.
