Space blankets

It was made from Nasa but we use it everyday life

Why did NASA make _ _ _ _ _ _ _?

First developed by NASA in 1964 for the US space program, the material consists of a thin sheet of Plastic that is coated with a metallic Reflecting agent, making it metallize usually gold or silver in color, which reflects up to 97% of radiated heat.

For use in space, polyimide kapton,substrate is usually employed due to its resistance to the hostile space environment, large temperature range (cryogenic to −260 °C and for short excursions up to over 480 °C), low outgrassing (making it suitable for vacuum use) and resistance to ultraviolet radiation. Aluminized , with foil thickness of 50 and 125 µm, was used on the Apollo lunar module The polyimide gives the foils their distinctive amber-gold color.

Space blankets are made by vaccum desposting a very precise amount of pure aluminum vapor onto a very thin, durable film substrate.NASA made it for astronauts to sleep better and to stay warm in space . Space blanket were also used to protect things that are fragile and space blankets are very thick.

How does this technology help us today

We use it for emergencies like to signal and used in first aid kit
  1. The obvious – wrapping in it for warmth.
  2. Use as an extra layer in sleeping bag for warmth.
  3. Stringing up as a signal device – not too tight – so it creates movement in the wind and increases your chance of being seen.
  4. Place it on the ground as a signal device and fold in different patterns to communicate a message.
  5. Melt snow by placing small amounts on space blanket in the sun and funnel into a container.
  6. Small rain shelter: over the corners of blanket.
  7. Use as material to write on, given you have a marker.
  8. Twist for extra rope material.
  9. Build a to carry small items.
  10. Twist and loop it through pants, and tie to make a belt.
  11. Tie off ends to create air space for an improvised flotation device.
  12. Cut off small pieces as part of lure to catch fish (they like shiny materials).
  13. Use sticks and foil to create a cup and boil water. Hold over the flame but not so close that it burns the foil. (The melting point of Mylar is listed at 254° C.)
  14. Use blanket as aluminum foil to warm food near the coals of a fire.
  15. Create a sling.
  16. Use as a tourniquet.
  17. Use as a compression bandage.
  18. Put in your kids’ backpack carrier to give them additional warmth.
  19. Use as gaiters, by wrapping around leg – secure with duct tape.
  20. Using as a pack liner (inside) or cover (outside) to keep clothes dry in rainy weather.
  21. Twist into an antenna to boost cell phone, radio, or TV reception.
  22. Improvised survival lingerie – be creative.
