When you think of NASA, you probably think of astronauts and space shuttles. What’s less known is that since its inception in 1958, the US space agency has gone well beyond making space travel possible.

Not content with putting a man on the moon, they’ve been busy creating new technology that’s found in many of the things we come into contact with everyday, to not only make our lives easier, but healthier. Here, the top six things we can thank our outer space friends for.

1. Indoor workouts

Yes, everyone’s go-to gym machine, the treadmill, was made for astronauts. One of the long-term effects of extended periods of time in zero gravity is that it weakens the body, causing bones to decrease in density and muscles to break down. While originally designed for astronauts to move their bodies to keep them from degenerating, they offer up a good solution for the rest of us to keep fit when the couch is calling.

2. Straighter teeth

Answering the prayers of high school kids the world over, NASA came up with a surefire solution to getting teased for having a mouth full of metal. How? By inventing the translucent ceramic that became the main component of the first “invisible” dental braces, which are now one of the best-selling orthodontic products of all time (and making sure 15-year-old boys get a date to the disco.)

3. Nike trainers

While working at NASA, an aeronautic engineer named Frank Ruddy took a technology used to create sturdy lightweight helmets and applied the same process to shoes. Ruddy thought if you were to hollow out the sole of a sneaker and put in its place a pad of interconnected cells, it would up the wearer’s comfort. From there, he pitched to Nike and the bouncy Nike Air shoes we all know and love were born.

4. Freeze dried fruit

You can thank NASA for those Insta-worthy smoothie toppings. After conducting research on space food in preparation for the Apollo missions, together with Nestle they came up with freeze drying – a process that involves dehydration of food to make it more convenient to transport. Side note: contrary to popular belief, NASA didn’t actually invent lunchbox favorite, Space Food Sticks. (We know, we’re still processing that one too.)

5. A comfortable sleep

Originally developed to protect aircraft passengers in the case of a collision, memory foam has made its way into everything from mattresses to sneakers. The foam works by feeding gas into pressurized areas to match the press being pushed against it (like your body after working a 12 hour day). It was first called “slow spring back foam,” then “temper foam.” The latter name was taken by a Swedish bedding company which created the Tempur-Pedic mattress.

6. Sunglasses

What’s now considered a fashion statement was the brainchild of NASA – a solution for scientists who were being exposed to damaging light that could impact their long-term vision. The UV filter glass developed was used to create technology they could protect their eyes with while operating laser equipment and now, what we shade our eyes with from the sun (and to up our summer selfie game).
