How is the space blanket used in space?

In space, a space blanket, often made of reflective material like Mylar, is used primarily for thermal insulation. It helps regulate temperature by reflecting heat back toward the wearer or equipment, protecting astronauts and sensitive instruments from extreme temperature fluctuations. Additionally, space blankets are lightweight and compact, making them easy to carry and deploy in various situations, such as emergencies or when extra warmth is needed in the cold vacuum of space.
