Spacewalking Meaning: Definition, Examples, and Translations
🚀
spacewalking
[ˈspeɪsˌwɔː.kɪŋ ]
Definition
extravehicular activity
Spacewalking, also known as extravehicular activity (EVA), refers to the act of performing tasks outside a spacecraft in outer space. It occurs when an astronaut exits the confines of their spacecraft to conduct experiments, perform repairs, or install equipment in the vacuum of space. These activities require specialized suits that provide life support and protect astronauts from extreme temperatures and radiation. Spacewalking is crucial for maintaining satellites and the International Space Station, allowing astronauts to engage directly with their environment.
Synonyms
EVA, extravehicular activity, outdoor space activity.
Examples of usage
- The astronaut completed a spacewalking mission to repair the satellite.
- During the spacewalking activity, the crew installed new solar panels.
- Spacewalking allows astronauts to conduct research in real space conditions.

Origin of 'spacewalking'
The term 'spacewalk' originated during the early days of human space exploration in the 1960s. The first successful spacewalk was conducted by Soviet cosmonaut Alexei Leonov on March 18, 1965, during the Voskhod 2 mission where he exited the spacecraft for about 12 minutes. This significant event marked a new era in space exploration, showcasing the capability of humans to operate outside the confined environment of a spacecraft. Since then, spacewalking has become a routine part of missions involving the International Space Station (ISS) and has allowed astronauts to perform critical tasks in the vacuum of space. The concept combines the excitement of exploration with the technical challenges of working in an environment that is vastly different from Earth's, leading to advancements in spacesuit technology and life support systems.
