Space Suit Components and Functions

The video tutorial explains how to build a NASA-approved EMU space suit. It covers the construction of the inner cooling garment, the multi-layered outerwear, the helmet and communication system, the life support backpack, and the control module. Each component is designed to protect astronauts from the harsh conditions of space, including temperature extremes, space dust, and the vacuum of space. The suit allows astronauts to float weightlessly while ensuring their safety and comfort.
