Spacewalk

A spacewalk, also known as an extravehicular activity (EVA), refers to the act of an astronaut leaving the confines of a spacecraft to perform tasks in the vacuum of space. This can include repairs, maintenance, scientific experiments, or construction work on space structures, like the International Space Station (ISS). Spacewalks are conducted while the astronaut is tethered to the spacecraft for safety and are typically performed in a pressurized spacesuit to provide life support and protection from the harsh space environment. Spacewalks are essential for the operation and upkeep of space equipment and contribute to the advancement of human understanding of outer space.
