<u>Explanation:</u>
The spacesuit protects the astronauts from various range of temperatures from -156°C to 121°C. Spacesuits have insulation as well as heaters. Spacesuits are equipped with thermal control systems to keep the temperature warm for the astronauts. The heaters in the spacesuit increases the temperature during extreme cold. When the astronaut's body temperature rises, the material absorbs the heat. When it drops, the material gives off the heat, providing warmth. Insulators uses micro-encapsulated phase-change materials.
