spacewalkers
Suited vacuum explorers
Spacewalkers are astronauts who exit their spacecraft to work in the vacuum of space, tethered to the vessel while performing repairs, installations, or experiments.
The term evokes the surreal image of humans walking where there is no ground: Spacewalkers spent six hours replacing a faulty solar panel.
