avaruusasut

Avaruusasut, commonly known as spacesuits, are protective garments worn by astronauts to sustain life in the vacuum of space. These suits are essentially self-contained spacecraft, providing a stable environment for the wearer. A primary function of an avaruusasu is to maintain a breathable atmosphere, supplying oxygen and removing carbon dioxide. They also regulate pressure, as the vacuum of space would otherwise cause bodily fluids to boil. Temperature control is another critical aspect, shielding the astronaut from extreme heat in direct sunlight and frigid temperatures in shadow.

Avaruusasut are designed to protect against micrometeoroids, small particles traveling at high velocities that could puncture the suit. They also offer protection from harmful solar radiation. Mobility is a key design consideration, allowing astronauts to perform tasks outside their spacecraft. This is achieved through a complex system of joints and flexible materials. Communication systems, including microphones and speakers, are integrated into the helmet to allow for contact with mission control and other crew members.

The development of avaruusasut has evolved significantly since the early days of space exploration, becoming more sophisticated and adaptable to the diverse requirements of various missions, from spacewalks to lunar surface operations. These suits are a vital piece of technology enabling humanity's presence beyond Earth's atmosphere.
