English: A space blanket is a blanket used to reduce heat loss. It is also known as an emergency blanket, first aid blanket, survival blanket, or isothermal blanket. They were developed by NASA in 1964 for use in the space program. They are often constructed of a thin sheet of metallized polyethylene terephthalate or other plastic coated with a silver- or gold-colored metallic reflecting agent.
