space walk
Tethered astronaut activity
A space walk is an activity in which an astronaut exits a spacecraft to work in the vacuum of space, tethered to the vehicle and wearing a pressurized suit.
The technical term is extravehicular activity or EVA.
The astronauts performed a six-hour space walk to repair the telescope.
Also spelled spacewalk.
