Extravehicular activity

A spacewalk, also known as an extravehicular activity (EVA), is any activity done by an astronaut outside a spacecraft beyond the Earth's atmosphere. The term "spacewalk" is often used to describe any activity outside a spacecraft, but technically, it refers to any activity outside a spacecraft in the vacuum of space. The first spacewalk was performed by Soviet cosmonaut Alexei Leonov on March 18, 1965, lasting 12 minutes and 9 seconds. In Hebrew, a spacewalk is called הילוך בחלל (hilukh bakhalal). In Russian, it is known as выход в открытый космос (vyhod v otkrytyy kosmos). In Chinese, the term is 太空行走 (tàikōng xíngzǒu). Spacewalks are crucial for various tasks such as repairing satellites, conducting scientific experiments, and maintaining the International Space Station (ISS). They require specialized training and equipment to protect astronauts from the hazards of space, including extreme temperatures, radiation, and micrometeoroids.
