Original Note:
Astronauts used jetpacks, officially called Manned Maneuvering Units (MMU) to move around during untethered space walks, although they were retired following the Space Shuttle Challenger disaster in 1986. Similar tech is still used for tethered space walks https://en.wikipedia.org/wiki/Manned_Maneuvering_Unit?wprov=sfti1
