Extravehicular Activity, often called EVA, refers to any activities performed by astronauts outside their spacecraft. This can include tasks like repairing equipment, conducting experiments, or simply enjoying the view of Earth from space. EVAs are crucial for maintaining the International Space Station and advancing our understanding of space. During an EVA, astronauts wear special suits known as space suits that protect them from the harsh environment of space. These suits provide oxygen, temperature control, and shielding from radiation. EVAs are carefully planned and executed, as they require precise coordination and communication between the astronauts and their team on the spacecraft.
