Foil blanket

A space blanket (depending on the function, also known as a Mylar blanket, first aid blanket, safety blanket, thermal blanket, weather blanket, or heat sheet) is an especially low-weight, low-bulk blanket made of heat-reflective thin plastic sheeting. They are used on the exterior surfaces of spacecraft for thermal control as well as by people.
