Is your vacuum cleaner from SPACE?
This week, Glenn is discussing his recent purchase of a Sputnik satellite, which has got many of us thinking about space and space technology. More specifically, we've been wondering how technology initially designed for use outside Earth's atmosphere impacted our lives down here on terra firma. The U.S. spent approximately $30 billion ($110 billion in today's money) between the Soviet launch of Sputnik in 1957 and the Moon Landing in 1969. What do we have to show for it besides some moon rocks?
As it turns out, a LOT of tech originally developed for space missions has made its way into products that most people use every day. From memory foam to cordless vacuums here are 5 pieces of space tech that you use every day:

Have you ever seen a photograph of an early camera, the big ones with the tripod and curtain, and wondered how we went from that to the tiny little cameras that fit inside your cellphone? Thank NASA for that brilliant innovation. When you are launching a spaceship or satellite out of the atmosphere, the space onboard comes at a premium. In order to make more room for other equipment, NASA wanted smaller, lighter cameras without compromising image quality, and the innovations made to accomplish this goal paved the way for the cameras in your phone.
Cordless vacuums and power tools

When exploring the moon, NASA wanted astronauts to use a drill to collect samples from the lunar surface. The problem: the moon has a severe lack of electrical outlets to power the drills. NASA tasked Black & Decker with developing a battery-powered motor powerful enough to take chunks out of the moon. The resulting motor was later adapted to power cordless power tools and vacuums in households across America.

What do distant stars and planets have in common with your eardrum? Both have their temperature read by the same infrared technology. The thermometers that can be found in medicine cabinets and doctors' offices across the world can trace their origins back to the astronomers at NASA who came up with the idea to measure the temperature of distant objects by the infrared light they emit.

This one may seem obvious, but sometimes you need a massively complicated problem to come up with simple solutions. During the Space Shuttle program, NASA had a big problem: hydroplaning. Hydroplaning is dangerous enough when you are going 70 miles an hour in your car, but when you're talking about a Space Shuttle landing at about 215 miles per hour, it's an entirely different animal. So what was NASA's space-age solution? Cutting grooves in the pavement to quickly divert water off the runway, a practice now common on many highways across the world.
Memory foam

If you've ever slept on a memory foam mattress, it probably won't come as a shock to find out that the foam was created to cushion falls from orbit. Charles Yotes was an astronautical engineer who is credited with the invention of memory foam. Yotes developed the technology for the foam while working on the recovery system for the Apollo command module. The foam was originally designed to help cushion the astronauts and their equipment during their descent from space. Now, the space foam is used to create some of the most comfortable mattresses on Earth. Far out.
