NASA cool.
An important part of our mission is keeping astronauts strong and healthy during stays in space, but did you know that our technology also helps keep you healthy? And the origins of these space innovations arenât always what youâd expect.
As we release the latest edition of NASA Spinoff, our yearly publication that celebrates all the ways NASA technology benefits us here on Earth, letâs look at some ways NASA is improving wellness for astronautsâand everyone else.
Without gravity to work against, astronauts lose bone and muscle mass in space. To fight it, they work out regularly. But to get them a good burn, we had to get creative. After all, pumping iron doesnât do much good when the weights float.
The solution? Elastic resistance. Inventor Paul Francis was already working on a portable home gym that relied on spiral-shaped springs made of an elastic material. He thought the same idea would work on the space station and after additional development and extensive testing, we agreed.
Our Interim Resistive Exercise Device launched in 2000 to help keep astronauts fit. And Francisâ original plan took off too. The technology perfected for NASA is at the heart of the Bowflex Revolution as well as a new line of handheld devices called OYO DoubleFlex, both of which enable an intensiveâand extensiveâworkout, right at home.
A key ingredient in a lifesaving treatment for many patients with congestive heart failure is made from a material a NASA researcher stumbled upon while working on a supersonic jet in the 1990s.
Today, a special kind of pacemaker that helps synchronize the left and right sides of the heart utilizes the unique substance known as LaRC-SI. The strong material can be cast extremely thin, which makes it easier to insert in the tightly twisted veins of the heart, and because it insulates so well, the pacemakerâs electric pulses go exactly where they should.
Since it was approved by the FDA in 2009, the device has been implanted hundreds of thousands of times.
Many people mistakenly think we created Teflon. Not true: DuPont invented the unique polymer in 1938. But an innovative new way to use the material was developed to help us transport samples back from Mars and now aids in stitching up surgery patients.
Our scientists would love to get pristine Martian samples into our labs for more advanced testing. One complicating factor? The red dust makes it hard to get a clean seal on the sample container. That means the sample could get contaminated on its way back to Earth.
The team building the cannister had an idea, but they needed a material with very specific properties to make it work. They decided to use Polytetrafluoroethylene (thatâs the scientific name for Teflon), which works really well in space.
The material we commonly recognize as Teflon starts as a powder, and to transform it into a nonstick coating, the powder gets processed a certain way. But process it differently, and you can get all kinds of different results.
For our Mars sample return cannister prototype, the powder was compressed at high pressures into a block, which was then forced through an extruder. (Imagine pressing playdough through a mold). It had never been done before, but the end result was durable, flexible and extremely thin: exactly what we needed.
And since the material can be implanted safely in the human bodyâit was also perfect as super strong sutures for after surgery.
It may surprise you, but the most polluted air you breathe is likely the air inside your home and office. Thatâs especially true these days with energy-efficient insulation: the hot air gets sealed in, but so do any toxins coming off the paint, furniture, cooking gas, etc.
This was a problem NASA began worrying about decades ago, when we started planning for long duration space missions. After all, thereâs no environment more insulated than a spaceship flying through the vacuum of space.
On Earth, plants are a big part of the âlife supportâ system cleaning our air, so we wondered if they could do the same indoors or in space.
The results from extensive research surprised us: we learned the most important air scrubbing happens not through a plantâs leaves, but around its roots. And now you can get the cleanest air out of your houseplants by using a special plant pot, available online, developed with that finding in mind: it maximizes air flow through the soil, multiplying the plantâs ability to clean your air.
Although this next innovation wasnât created with pollution in mind, itâs now helping keep an eye on one of the biggest greenhouse gasses: methane.
We created this tiny methane âsnifferâ to help us look for signs of life on Mars. On Earth, the biggest source of methane is actually bacteria, so when one of our telescopes on the ground caught a glimpse of the gas on Mars, we knew we needed to take a closer look.
We sent this new, extremely sensitive sensor on the Curiosity Rover, but we knew it could also be put to good use here on our home planet. Â We adapted it, and today it gets mounted on drones and cars to quickly and accurately detect gas leaks and methane emissions from pipelines, oil wells and more.
The sensor can also be used to better study emissions from swamps and other natural sources, to better understand and perhaps mitigate their effects on climate change.
Thereâs been a lot of news lately about DNA editing: can genes be changed safely to make people healthier? Should they be?
As scientists and ethicists tackle these big questions, they need to be sure they know exactly whatâs changing in the genome when they use the editing tools that already exist.
Well, thanks to a tool NASA helped create, we can actually highlight any abnormalities in the genetic code with special fluorescent âpaint.â
But thatâs not all the âpaintâ can do. We actually created it to better understand any genetic damage our astronauts incurred during their time in space, where radiation levels are far higher than on Earth. Down here, it could help do the same. For example, it can help doctors select the right cancer treatment by identifying the exact mutation in cancer cells.
You can learn more about all these innovations, and dozens more, in the 2019 edition of NASA Spinoff. Read it online or request a limited quantity print copy and weâll mail it to you!
