A space suit is a specialized garment designed to protect astronauts while they work in the harsh environment of outer space. It provides life support by supplying oxygen, removing carbon dioxide, and regulating temperature. The suit also shields astronauts from radiation and micrometeoroids, ensuring their safety during spacewalks or missions on other celestial bodies. Space suits are equipped with various features, including a helmet with a visor for visibility and communication systems. They are often used during missions conducted by organizations like NASA and are essential for activities such as repairing satellites or conducting scientific experiments outside the International Space Station.
