EVA (Extravehicular Activity)
Extravehicular Activity (EVA) refers to activities that astronauts perform outside their spacecraft while in space. This includes tasks like repairs, maintenance, and scientific research, as well as activities during spacewalks for exploration. EVAs are crucial for operations on the International Space Station and during missions to the Moon or Mars. Astronauts wear specially designed spacesuits to protect them from the harsh conditions of space, including extreme temperatures and lack of oxygen. Each EVA requires careful planning and training to ensure the safety and success of the mission.
