Extravehicular Activity (EVA)

Extravehicular Activity (EVA) refers to any work performed outside a spacecraft or space station in the vacuum of space. It typically involves astronauts donning specialized suits that provide life support, protection, and mobility. EVAs are used for tasks such as repairs, maintenance, installing new equipment, or scientific experiments. Conducted in the harsh environment of space, these activities require careful planning and precision to ensure safety. EVAs are crucial for spacecraft upkeep and scientific research beyond Earth's atmosphere, often called "spacewalks," but they are technically more precise as they happen outside the confines of the spacecraft.
