The Iconic Photos from STS-41B: Documenting the First Untethered Spacewalk

As astronaut Bruce McCandless II flew the Manned Maneuvering Unit (MMU) out of the space shuttle Challenger’s payload bay for the first time on February 7, 1984, many in the agency were fearful about the use of a self-propelled and untethered backpack in space. (Previous spacewalkers remained connected to the vehicle with tethers.
