Extravehicular activities (EVAs) refer to tasks performed by astronauts outside their spacecraft while in space. These activities are essential for various missions, including repairs, maintenance, and scientific experiments. EVAs allow astronauts to work in the vacuum of space, often using specialized suits to protect them from harsh conditions.
During an EVA, astronauts may use tools and equipment to complete their objectives. The International Space Station (ISS) is a common site for EVAs, where astronauts conduct repairs or install new technology. EVAs are carefully planned and executed to ensure the safety and success of the mission.
