spacewalker
Suited void explorer
A spacewalker is an astronaut who performs a spacewalk—working outside a spacecraft while in orbit.
The term emphasizes the person rather than the activity: The spacewalker spent six hours repairing the station's solar panels.
Also called an extravehicular activity (EVA) specialist in technical contexts.
