6 Ways NASA Technology Makes You Healthier

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 aren’t always what you’d 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, let’s look at some ways NASA is improving wellness for astronauts—and everyone else.

1. Weightless weight-lifting

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 doesn’t 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 Francis’ 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 intensive—and extensive—workout, right at home.

2. Polymer coating keeps hearts beating

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 pacemaker’s 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.

3. Sutures strong enough for interplanetary transport

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 (that’s 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 body—it was also perfect as super strong sutures for after surgery.

4. Plant pots that clean the air

It may surprise you, but the most polluted air you breathe is likely the air inside your home and office. That’s 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, there’s no environment more insulated than a spaceship flying through the vacuum of space.

On Earth, plants are a big part of the “life support” 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 plant’s 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 plant’s ability to clean your air.

5. Gas sensor detects pollution from overhead

Although this next innovation wasn’t created with pollution in mind, it’s now helping keep an eye on one of the biggest greenhouse gasses: methane.

We created this tiny methane “sniffer” 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. 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.

6. DNA “paint” highlights cellular damage

There’s 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 what’s 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 “paint.”

But that’s not all the “paint” 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 we’ll mail it to you!

How Well Do you Know Neptune?

Dark, cold and whipped by supersonic winds, Neptune is the last of the hydrogen and helium gas giants in our solar system. More than 30 times as far from the sun as Earth, the planet takes almost 165 Earth years to orbit our sun! In fact, in 2011, Neptune completed its first orbit since its discovery in 1846.

Here are a few things you might not know about the windiest planet:

If the sun were as tall as a typical front door, the Earth would be the size of a nickel and Neptune would be about as big as a baseball.

Neptune orbits our sun, a star. Neptune is the eighth planet from the sun at a distance of about 4.5 billion km (2.8 billion miles) or 30.07 AU.

One day on Neptune takes about 16 hours (the time it takes for Neptune to rotate or spin once)

Neptune makes a complete orbit around the sun (a year in Neptunian time) in about 165 Earth years (60,190 Earth days)

Neptune has six rings

Voyager 2 is the only spacecraft to have visited Neptune

Neptune has 13 moons. They are named after various sea gods and nymphs in Greek mythology

Did you know that Neptune has storms?

Similar to Jupiter, Neptune has storms that create gigantic spots in its atmosphere…well, it did. When Voyager 2 flew past Neptune in 1989, it tracked and imaged the “Great Dark Spot” — a storm larger than the entire Earth! When the Hubble Space Telescope imaged Neptune the spot had disappeared, only to be replaced with two smaller storms, which in turn also disappeared.

The Smoke From a (Not-so) Distant Fire

Flying directly through thick plumes of smoke may seem more harrowing than exciting. But for members of the CAMP2Ex science team, the chance to fly a P-3 Orion straight through clouds of smoke billowing off fires from Borneo this week was too good an opportunity to pass up.

CAMP2Ex stands for the Cloud, Aerosol and Monsoon Processes in the Philippines Experiment. The 2, by the way, is silent.

It’s a field campaign based out of Clark in the Philippines, flying our P-3, a Learjet and collaborating with researchers on the research vessel Sally Ride to understand how tiny particles in the atmosphere affect cloud formations and monsoon season.

The tiny aerosol particles we’re looking at don’t just come from smoke. Aerosol particles also come from pollution, billowing dust and sea salt from the ocean. They can have an outsized effect on weather and climate, seeding clouds that bring rain and altering how the atmosphere absorbs the Sun’s heat.

The smoke we were flying Monday came from peat fires, burning through the soil. That’s pretty unusual — the last time Borneo had these kind of fires was in 2015, so it was a rare opportunity to sample the chemistry of the smoke and find out what’s mixing with the air.

The planes are loaded with instruments to learn more about aerosol particles and the makeup of clouds, like this high-speed camera that captures images of the particles in flight.

One instrument on the plane collects droplets of cloud water as the plane flies through them, and on the ground, we test how acidic and what kind of particles form the cloud drops.

All of these measurements are tools in improving our understanding of the interaction between particles in the air and clouds, rainfall and precipitation in the Pacific Ocean.

What's Up? - May 2018

What’s Up For May?

The Moon and Saturn meet Mars in the morning as our InSight spacecraft launches to the Red Planet on May 5!

You won't want to miss red Mars in the southern morning skies this month.

InSight, our first mission to explore Mars' deep interior, launches on May 5th with a launch window that begins at 4:05 a.m. PDT and lasts for two hours.

Some lucky viewers in central and southern California and even parts of the Mexican Pacific coast will get a chance to see the spacecraft launch with their unaided eyes AND its destination, Mars, at the same time.

Mars shines a little brighter than last month, as it approaches opposition on July 27th. That's when Mars and the Sun will be on opposite sides of the Earth. This will be Mars' closest approach to Earth since 2003!

Compare the planet's increases in brightness with your own eyes between now and July 27th.

The Eta Aquarid meteor shower will be washed out by the Moon this month, but if you are awake for the InSight launch anyway, have a look. This shower is better viewed from the southern hemisphere, but medium rates of 10 to 30 meteors per hour MAY be seen before dawn.

Of course, you could travel to the South Pacific to see the shower at its best!

There's no sharp peak to this shower--just several nights with good rates, centered on May 6th.

Jupiter reaches opposition on May 9th, heralding the best Jupiter-observing season, especially for mid-evening viewing. That's because the king of the planets rises at sunset and sets at dawn.

Wait a few hours after sunset, when Jupiter is higher in the sky, for the best views. If you viewed Jupiter last month, expect the view to be even better this month!

Watch the full What’s Up for May Video:

There are so many sights to see in the sky. To stay informed, subscribe to our What’s Up video series on Facebook. Make sure to follow us on Tumblr for your regular dose of space: http://nasa.tumblr.com.

Meet NGC 2841

Location: In the constellation Ursa Major

Type: Flocculent spiral galaxy

Discovered by: William Herschel

NGC 2841 is a beautiful example of a flocculent spiral galaxy – a type with discontinuous, featherlike, and patchy arms. A bright cusp of starlight distinguishes the galaxy's center from the dust lanes that outline the group of almost white middle-aged stars. The far younger blue stars trace the spiral arms.

Find out more information about NGC 2841 here.

Right now, the Hubble Space Telescope is exploring #GalaxiesGalore! Find more galaxy content and spectacular new images by following along on Hubble’s Twitter, Facebook, and Instagram.

NASA Spotlight: Christina Hernandez, NASA Mars 2020 Rover Instrument Engineer

“I was in love with the beauty of space. It was my introduction to appreciating the beauty of complex, chaotic things—black holes, giant gas planets, or killer asteroids—that got my imagination riled up.“ -Christina Hernandez

Christina Hernandez, a space enthusiast and self-proclaimed nerd, is an aerospace engineer at our Jet Propulsion Laboratory in California where she works as an instrument engineer on our newest rover mission – Mars2020. The Mars2020 rover is a robotic scientist that is launching to the Red Planet next year. If you would like to launch to the Red Planet as well, you can Send Your Name to Mars along with millions of other people! Christina’s job is to make sure that the instruments we send to the Martian surface are designed, built, tested and operated correctly so we can retrieve allll the science. When she isn’t building space robots, she loves exploring new hiking trails, reading science fiction and experimenting in the kitchen. Christina took a break from building our next Martian scientist to answer some questions about her life and her career:

If you could go to Mars, would you? And what are three things you’d bring with you?

Only if I had a round trip ticket! I like the tacos and beach here on Earth too much. If I could go, I would bring a bag of Hot Cheetos, a Metallica album, and the book On the Shoulders of Giants.

If you could name the Mars2020 rover, what would you name it and why?

Pilas, a reference to a phrase my family says a lot, ponte las pilas. It literally means put your batteries on or in other words, get to work, look alive or put some energy into it. Our rover is going to need to have her batteries up and running for all the science she is going to be doing! Luckily, the rover has a radioisotope thermoelectric generator (RTG) to help keep the batteries charged!

What’s been your most memorable day at NASA?

It’s been seeing three of the instruments I worked on getting bolted and connected to the flight rover. I’ll never forget seeing the first 1’s and 0’s being exchanged between the rover compute element (RCE), the rover’s on-board brain, and the instruments’ electronics boxes (their brains). I am sure it was a wonderful conversation between the two!

It’s a long journey to get from Earth to Mars. What would be on your ultimate road trip playlist?

Metallica, The Cure, Queen, Echo and the Bunnymen, Frank Sinatra, Ramon Ayala, AC/DC, Selena, Los Angeles Azules, ughhhh – I think I just need a Spotify subscription to Mars.

What is one piece of advice you wish someone would’ve told you?

Take your ego out of the solution space when problem solving.

Do you have any secret skills, talents, or hobbies?

I love reading. Each year I read a minimum of 20 books, with my goal this year being 30 books. It’s funny I increased my goal during what has definitely been my busiest year at work. I recently got into watercolor painting. After spending so much time connected at work, I started looking for more analog hobbies. I am a terrible painter right now, but I painted my first painting the other day. It was of two nebulas! It’s not too bad! I am hoping watercolor can help connect me more to the color complexities of nature...and it’s fun!

What’s a project or problem that you would love the ability to tackle/work on?

I would love to work on designs for planetary human explorers. So far, I have focused on robotic explore, but when you throw a “loveable, warm, squishy thing” into the loop, its creates a different dimension to design – both with respect to operability and risk.

Thanks so much Christina! The Mars2020 rover is planned to launch on July 17, 2020, and touch down in Jezero crater on Mars on February 18, 2021.
