2014 marks the 45th anniversary since Neil Armstrong first walked on the moon, and 3 years since NASA’s space shuttle program was grounded.
America is not currently launching into space, but the movie Gravity and the TV show Cosmos have reminded Americans of the wonder that is our universe.
In the time since NASA’s last shuttle was in space, they have been focusing on advancing shuttle technology so that space exploration will be safer and more efficient once we return.
The first thing they have done is upgrading the external tank’s thermal protection system.
The tank is insulated with closed cell foam, and then covered with another material, called ablator, to further dissipate heat.
The closed cell foam is so effective that it maintains the shuttle’s liquid nitrogen fuel’s temperature of 423 degrees below zero Fahrenheit.
And that’s not all it does; this spray foam can also endure the whopping 2,200 degrees Fahrenheit temperature during the shuttle’s ascent into space.
It’s pretty inspiring to think of all of the technological developments that have come since spray foam insulation’s first invention.
Unlike Foam It Green’s spray foam kits, the shuttle’s foam is applied mostly by computer automated systems.
But it is still very cool to know that the foam in your walls is a distant cousin of the foam that will one day launch into space.
And when NASA shuttles finally return to space, we hope that you can watch the launch, comfortably from your spray foam insulated home.
