spacewalks
Tethered astronaut outings
Spacewalks are excursions outside a spacecraft while in orbit, where astronauts float in the vacuum of space wearing pressurized suits.
The technical term is extravehicular activity (EVA).
Astronauts perform spacewalks to repair equipment, conduct experiments, or assemble structures like the International Space Station: The repair required three spacewalks over six days.
