A spacewalk, also known as an extravehicular activity (EVA), is when an astronaut exits their spacecraft to perform work in the vacuum of space. This can involve repairs, maintenance, or scientific experiments outside the International Space Station (ISS) or other spacecraft. Astronauts wear specially designed spacesuits to protect them from the harsh environment of space, including extreme temperatures, radiation, and micrometeoroids. Spacewalks are crucial for the upkeep of space stations and for conducting research that can only be done outside the spacecraft.
