Extravehicular mobility unit (EMU)

The Extravehicular Mobility Unit (EMU) is a specialized spacesuit used by astronauts when they perform tasks outside their spacecraft, such as repairing satellites or conducting scientific experiments in space. The suit is designed to provide life support by supplying oxygen, maintaining temperature, and protecting against space hazards like micrometeoroids and radiation. It features a helmet with a visor to shield against sunlight and a communication system, allowing astronauts to talk to their team while working. Overall, the EMU ensures astronauts can work safely and effectively in the harsh environment of space.
