Spacewalk: meaning, definitions and examples
🚀
spacewalk
[ ˈspeɪsˌwɔk ]
astronomy activity
A spacewalk refers to an activity where astronauts leave the confines of their spacecraft to perform tasks outside in space. This can involve repairs, maintenance, or conducting scientific experiments. Spacewalks are crucial for the upkeep of space stations and satellites and allow astronauts to test new equipment intended for future missions. They require extensive training and preparation to ensure the safety of the astronauts in the vacuum of space.
Synonyms
EVA, extravehicular activity.
Examples of usage
- The astronaut performed a spacewalk to repair the satellite.

Etymology
The term 'spacewalk' was first coined in the early 1960s during the era of space exploration when astronauts began to conduct activities outside their spacecraft. The first human to conduct a spacewalk was Soviet cosmonaut Alexei Leonov, who exited his spacecraft on March 18, 1965, during the Voskhod 2 mission. This term combines the words 'space', referring to the vast void outside Earth’s atmosphere, and 'walk', indicating the physical activity of moving outside the confines of the spacecraft while secured by a tether. Over the years, the practice of spacewalking has evolved with advancements in technology, safety protocols, and the understanding of microgravity environments. Today, spacewalks are integral to the operation of the International Space Station and other space missions.
