In the 1950s, Mylar was first introduced in a commercial capacity as bathroom wall coverings. Although it didn’t last long in this manner, NASA saw potential in the plastic metal coated film material. NASA was confident in the material’s reflective capabilities in protecting against the sun while also retaining heat. Neil Armstrong’s space suit he wore on his historical moon walk was made with gold Mylar. The space blanket was soon a fixture of space travel.
Since it’s beginnings over 45 years ago, this blanket has become a necessity in survival kits and camping packs. Although the metal used is aluminum, they are capable of preventing up to 97% of heat loss. The metal reflects the sun’s rays while retaining and helping to maintain body heat.
Space blankets have many uses in emergency situations. Rescue vehicles, like ambulances and fire trucks, have started keeping them in stock to use when tending to victims of tragedy. Water crafts and agencies, like the Coast Guard, use space blankets for rescues.
Campers, hunters, and hikers are learning that space blankets are necessary parts of their gear. I the event that you get lost or stranded, a space blanket can keep you safe from hypothermia or frost bite. They also have many other ways to be used in a survival application.
Let’s say that you’re hiking and you get lost. Basic survival tips tell you to stay put. What are you supposed to do to ensure you stay alive long enough to be found? Wrap yourself in a space blanket. It will keep your core temperature from getting dangerously low. In extreme weather conditions, the blanket can be put underneath your clothing to maximize protection.
If it starts raining or snowing and you couldn’t find shelter, you would be stuck, which is dangerous. If you pack multiple blankets, you could use one for your body and others to create a makeshift shelter. Space blankets are windproof and waterproof. If you get stuck in a hot desert, space blankets can be used to create shade to reduce sun and heat exposure.
It is not uncommon to find space blankets in other forms. Because of its capabilities, a space blanket can also be in a sack form, called a survival sack, which protects you if you have to lay on open ground. Some versions, called casualty blankets, are used by military personnel; these space blankets serve the same purpose but they have an olive colored outer layer for the added strength needed for many uses.
If you have a survival kit or you are making plans to go hunting, camping, or hiking, you should make sure that space blankets are included in your list of things to pack. Most people assume that if the need were to arise, they could build a fire to help them stay warm. This alone cannot guarantee that you will survive, especially if it begins to snow or rain. It is not too safe to have a fire in an enclosed area either; there isn’t always proper ventilation for the smoke.
A space blanket is ultra thin and almost weightless. In its folded form, it takes up a small amount of space, about as much as a folded handkerchief. Space blankets are important parts of survival and rescue gear. Some people carry one around with them everywhere, in their cars or purses. In this way, you would be prepared in an emergency.
