NASA Technology in Your Life

How does NASA technology benefit life on Earth? It probably has an impact in more ways than you think! Since 1976, our Spinoff program has profiled nearly 2,000 space technologies that have transformed into commercial products and services. In celebration of Spinoff’s 40th year of publication, we’ve assembled a collection of spinoffs that have had the greatest impact on Earth. 

Take a look and see how many you utilize on a regular basis:

Digital Image Sensors

Whether you take pictures and videos with a DSLR camera or a cell phone, or even capture action on the go with a device like a GoPro Hero, you’re using NASA technology. The CMOS active pixel sensor in most digital image- capturing devices was invented when we needed to miniaturize cameras for interplanetary missions. This technology is also widely used in medical imaging and dental X-ray devices.

Enriched Baby Formula

While developing life support for Mars missions, NASA-funded researchers discovered a natural source for an omega-3 fatty acid previously found primarily in breast milk that plays a key role in infant development. The ingredient has since been added to more than 90% of infant formula on the market and is helping babies worldwide develop healthy brains, eyes and hearts.

NASTRAN Software

NASTRAN is a software developed by our engineers that performs structural analysis in the 1960s. Still popular today, it’s been used to help design everything from airplanes and cars to nuclear reactors and even Disney’s Space Mountain roller coaster.

Food Safety Standards

Looking to ensure the absolute safety of prepackaged foods for spaceflight, we partnered with the Pillsbury Company to create a new, systematic approach to quality control. Now known as Hazard Analysis and Critical Control Points (HACCP), the method has become an industry standard that benefits consumers worldwide by keeping food free from a wide range of potential chemical, physical and biological hazards.

Neutral Body Posture Specifications

What form does the human body naturally assume when all physical influences, including the pull of gravity, stop affecting it? We conducted research to find out using Skylab, America’s first space station, and later published specifications for what it called neutral body posture. The study has informed seat designs in everything from airplanes and office chairs to several models of Nissan automobiles.

Advanced Water Filtration

We recently discovered unexpected sources of water on the moon and Mars, but even so, space remains a desert for human explorers, and every drop must be recycled and reused. A nano filter devised to purify water in orbit is currently at work on Earth, in devices that supply water to remote villages as well as in a water bottle that lets hikers and adventurers stay hydrated using streams and lakes.

Swimsuit Designs

Wind-tunnel testing at our Langley Research Center played a key role in the development of Speedo’s LZR Racer swimsuit, proving which materials and seams best reduced drag as a swimmer cuts through the water. The swimsuit made a splash during its Olympic debut in 2008, as nearly every medal winner and world-record breaker wore the suit.

Air Purifier

When plants grow, they release a gas called ethylene that accelerates decay, hastening the wilting of flowers and the ripening of fruits and vegetables. Air circulation on Earth keeps the fumes from building up, but in the hermetically sealed environment of a spacecraft, ethylene poses a real challenge to the would-be space farmers. We funded the development of an ethylene scrubber for the International Space Station that has subsequently proved capable of purifying air on Earth from all kinds of pathogens and particulates. Grocery stores use it to keep produce fresh longer. It’s also been marketed for home use and has even been embraced by winemakers, who employ the scrubber to keep aging wine in barrels free from mold, mildew and musty odors.

Scratch-Resistant, UV-Reflective Lenses

Some of the earliest research into effective scratch-resistant coatings for prescription and sunglass lenses drew from work done at Ames Research Center on coatings for astronaut helmet visors and plastic membranes used in water purification systems. In the 1980s, we developed sunlight-filtering lenses to provide eye protection and enhance colors, and these lenses have found their way into sunglasses, ski goggles and safety masks for welders.

Dustbuster

An Apollo-era partnership with Black & Decker to build battery-operated tools for moon exploration and sample collection led to the development of a line of consumer, medical and industrial hand-held cordless tools. This includes the popular Dustbuster cordless vacuum.

Five Ways Your Holidays Might Be Similar to the Crew on the Space Station

The holiday season is here! You might think that your celebrations are WAY different than what is done on the International Space Station, but you might be surprised…Here are a few ways your holidays might be similar to the crew on the space station:

1. You’re Instagramming All Your Decorations

Yep! Just like on Earth, the space station crew has the capability to use social media while on orbit. If you don’t follow them, you should check it out and get an out of this world perspective of what life is like on the International Space Station. (Expedition 34 crew members assemble in the Unity node of the space station for a brief celebration of the Christmas holiday on Dec. 24, 2012.)

2. You Have to Make Sure to Call Your Relatives

You don’t want to forget to wish Aunt Sue “Happy Holidays”, she might not send you a gift next year! The crew on the space station have the ability to talk to their loved ones every day. (Cosmonaut Mikhail Tyurin, and astronauts Michael E. Lopez-Alegria and Sunita L. Williams conduct a teleconference on Dec. 25, 2006.)

3. The Family Photos Never Seem to End

The crew on the station might not be related by blood, or even country of birth, but they share living space, meals and time together just like a family on Earth. And when it comes to the holidays, you bet they’ll be snapping pictures to capture the moments. (The six Expedition 30 crew members assemble in the U.S. Lab aboard the space station for a brief celebration of the Christmas holiday on Dec. 25, 2011.)

4. Meal Prep is a Task Shared by All

When you’re making food for multiple people, everyone needs to pitch in and help…the crew on the space station included! (Astronauts Michael Fincke, Sandra Magnus and cosmonaut Yury Lonchakov, pose for a photo as they prepare to share a Christmas meal on the space station on Dec. 25, 2008.)

5. Eating Cookies is a Must

What would the holidays be like without eating cookies? They even have the chance to eat them in space…pretty cool! (Astronauts Michael Fincke and Sandra Magnus hold Christmas cookies while posing for a photo near the galley on the space station on Dec. 25, 2008.)

Earth By The Numbers

Ahhh, Earth. Our home planet and oasis in space. You’re probably very familiar with this world, but here are a few things you may not know about our “Pale Blue Dot” of a planet.

From the vantage point of space, we are able to observe our planet globally using sensitive instruments to understand the delicate balance among its oceans, air, land and life. Satellite observations help study and predict weather, drought, pollution, climate change and many other phenomena that affect the environment, economy and society. 

1. Known to Harbor Life

Of the nine planets, countless asteroids and meteors in our solar system, Earth is the only one known to harbor life. It has a thin layer of atmosphere that separates us from the coldness of space.

2.  All By Its Lonesome

Unlike some other planets in the system that have three or more rings, the Earth has zero, but we do have one lonely moon that orbits us.

3. Moving At The Speed Of Life

Earth is the third planet from the sun and is located about 93,000,000 miles away from it. At this distance, the Earth moves at 66,000 miles per hour through space to complete its 365 day rotation.

4. You Can Breathe Easy

Earth’s atmosphere is 78% nitrogen, 21% oxygen and about 1% other ingredients. Most other planets in our solar system have an atmosphere, but Earth’s is the only one that’s breathable. 

5. For Real?

Did you grow up thinking that each calendar year was 365 days long? It’s actually 365 days, 5 hours, 48 minutes and 56 seconds...in other words, it’s 365.2564 days long. This is why an extra day is add during a leap year: to help offset this time difference. 

6. Far Out

We measure the distance of planets in our solar system in a measurement known as an Astronomical Unit, or AU. This measurement is based on the distance of the Earth from the sun. Earth is one AU from the sun, while Mars is 1.52 AU and Jupiter is 5.2 AU.

7. Taking Selfies...Before It Was Cool

The first ever photo of Earth was captured on October 24, 1946 when a V-2 test rocket was launched into space from New Mexico.

8. Slumped Over Already

The Earth doesn’t sit upright like you would think. It’s actually sitting on its side a bit, or rotational axis as it’s called, the Earth sits at a 23.45 degree rotational axis spin.

9. How Original...

How did it get the name Earth? The name “Earth” is at least 1,000 years old. All the planets in our system are named after Greek and Roman gods and goddesses, except for Earth. The name itself is of English and German origin and simply means “ground”.

55 Cancri e: Where Skies Sparkle Above a Never-ending Ocean of Lava

We’ve discovered thousands of exoplanets – planets beyond our solar system – so far. These worlds are mysterious, but observations from telescopes on the ground and in space help us understand what they might look like.

Take the planet 55 Cancri e, for instance. It’s relatively close, galactically speaking, at 41 light-years away. It’s a rocky planet, nearly two times bigger than Earth, that whips around its star every 18 hours (as opposed to the 365 days it takes our planet to orbit the Sun. Slacker).

The planet’s star, 55 Cancri, is slightly smaller than our Sun, but it’s 65 times closer than the Sun is to Earth. Imagine a massive sun on the horizon! Because 55 Cancri e is so close to its star, it’s tidally locked just like our Moon is to the Earth. One side is always bathed in daylight, the other is in perpetual darkness. It’s also hot. Really hot. So hot that silicate rocks would melt into a molten ocean of melted rock. IT’S COVERED IN AN OCEAN OF LAVA. So, it’s that hot (between 3,140 degrees and 2,420 degrees F).

Scientists think 55 Cancri e also may harbor a thick atmosphere that circulates heat from the dayside to the nightside. Silicate vapor in the atmosphere could condense into sparkling clouds on the cooler, darker nightside that would reflect the lava below. It’s also possible that it would rain sand on the nightside, but … sparkling skies!

This animation blinks between two images of our Mars Phoenix Lander. The first – dark smudges on the planet’s surface. The second – the same Martian terrain nearly a decade later, covered in dust. Our Mars orbiter captured this shot as it surveyed the planet from orbit: the first in 2008. The second: late 2017.

In August 2008, Phoenix completed its three-month mission studying Martian ice, soil and atmosphere. The lander worked for two additional months before reduced sunlight caused energy to become insufficient to keep the lander functioning. The solar-powered robot was not designed to survive through the dark and cold conditions of a Martian arctic winter.

Sometimes... there’s more than meets the eye. 👀 You’re looking at two very different takes on an iconic image. ⁣

Human eyes can see only a small portion of the range of radiation given off by the objects around us. We call this wide array of radiation the electromagnetic spectrum, and the part we can see visible light.

In the first image, researchers revisited one of Hubble Space Telescope’s most popular sights: the Eagle Nebula’s Pillars of Creation. Here, the pillars are seen in infrared light, which pierces through obscuring dust and gas and unveil a more unfamiliar — but just as amazing — view of the pillars. ⁣ ⁣ The entire frame is peppered with bright stars and baby stars are revealed being formed within the pillars themselves. The image on the bottom is the pillars in visible light.

Love Letters from Space

Love is in the air, and it’s out in space too! The universe is full of amazing chemistry, cosmic couples held together by gravitational attraction, and stars pulsing like beating hearts.

Celestial objects send out messages we can detect if we know how to listen for them. Our upcoming Nancy Grace Roman Space Telescope will help us scour the skies for all kinds of star-crossed signals.

Celestial Conversation Hearts

Communication is key for any relationship – including our relationship with space. Different telescopes are tuned to pick up different messages from across the universe, and combining them helps us learn even more. Roman is designed to see some visible light – the type of light our eyes can see, featured in the photo above from a ground-based telescope – in addition to longer wavelengths, called infrared. That will help us peer through clouds of dust and across immense stretches of space.

Other telescopes can see different types of light, and some detectors can even help us study cosmic rays, ghostly neutrinos, and ripples in space called gravitational waves.

Intergalactic Hugs

This visible and near-infrared image from the Hubble Space Telescope captures two hearts locked in a cosmic embrace. Known as the Antennae Galaxies, this pair’s love burns bright. The two spiral galaxies are merging together, igniting the birth of brand new baby stars.

Stellar nurseries are often very dusty places, which can make it hard to tell what’s going on. But since Roman can peer through dust, it will help us see stars in their infancy. And Roman’s large view of space coupled with its sharp, deep imaging will help us study how galaxy mergers have evolved since the early universe.

Cosmic Chemistry

Those stars are destined to create new chemistry, forging elements and scattering them into space as they live, die, and merge together. Roman will help us understand the cosmic era when stars first began forming. The mission will help scientists learn more about how elements were created and distributed throughout galaxies.

Did you know that U and I (uranium and iodine) were both made from merging neutron stars? Speaking of which…

Fatal Attraction

When two neutron stars come together in a marriage of sorts, it creates some spectacular fireworks! While they start out as stellar sweethearts, these and some other types of cosmic couples are fated for devastating breakups.

When a white dwarf – the leftover core from a Sun-like star that ran out of fuel – steals material from its companion, it can throw everything off balance and lead to a cataclysmic explosion. Studying these outbursts, called type Ia supernovae, led to the discovery that the expansion of the universe is speeding up. Roman will scan the skies for these exploding stars to help us figure out what’s causing the expansion to accelerate – a mystery known as dark energy.

Going Solo

Plenty of things in our galaxy are single, including hundreds of millions of stellar-mass black holes and trillions of “rogue” planets. These objects are effectively invisible – dark objects lost in the inky void of space – but Roman will see them thanks to wrinkles in space-time.

Anything with mass warps the fabric of space-time. So when an intervening object nearly aligns with a background star from our vantage point, light from the star curves as it travels through the warped space-time around the nearer object. The object acts like a natural lens, focusing and amplifying the background star’s light.

Thanks to this observational effect, which makes stars appear to temporarily pulse brighter, Roman will reveal all kinds of things we’d never be able to see otherwise.

Roman is nearly ready to set its sights on so many celestial spectacles. Follow along with the mission’s build progress in this interactive virtual tour of the observatory, and check out these space-themed Valentine’s Day cards.

Hello! When preparing for a mission what are your primary concerns for the astronauts safety- what do you focus on with the most intensity to feel confident in sending a crew up?

Space Food

Food: everyone needs it to survive and in space there’s no exception. Let’s take a closer look at what astronauts eat while in space. 

Since the start of human spaceflight, we’ve worked to improve the taste, texture and shelf life of food for our crews. Our food scientists are challenged with developing healthy menus that can meet all of the unique requirements for living and working in the extreme environment of space.

Consider the differences of living on Earth and in space. Food scientists must develop foods that will be easier to handle and consume in a microgravity environment. These food products require no refrigeration and provide the nutrition humans need to remain healthy during spaceflight.

Freeze drying food allows food to remain stable at ambient temperatures, while also significantly reducing the weight.

Fun Facts About Space Food:

Astronauts use tortillas in many of their meals

Tortillas provide an edible wrapper to keep food from floating away. Why tortillas and not bread? Tortillas make far less crumbs and can be stored easier. Bread crumbs could potentially float around and get stuck in filters or equipment.

The first food eaten by an American astronaut in space: Applesauce

The first American astronaut to eat in space dined on applesauce squeezed from a no-frills, aluminum toothpaste-like tube. Since then, food technology has cooked up better ways to prepare, package and preserve space fare in a tastier, more appetizing fashion.

All food that is sent to the space station is precooked

Sending precooked food means that it requires no refrigeration and is either ready to eat or can be prepared simply by adding water or by heating. The only exception are the fruit and vegetables stowed in the fresh food locker.

Salt and pepper are used in liquid form on the International Space Station

Seasonings like salt and pepper have to be used in liquid form and dispensed through a bottle on the space station. If they were granulated, the particles would float away before they even reached the food.

Food can taste bland in space

Some people who live in space have said that food is not the same while in microgravity. Some say that it tastes bland, some do not like their favorite foods and some love to eat foods they would never eat on Earth. We believe this phenomenon is caused by something called “stuffy head” This happens when crew member’s heads get stopped up because blood collects in the upper part of the body. For this reason, hot sauce is used A LOT on the space station to make up for the bland flavor.

Astronaut ice cream is not actually eaten on the space station

Even though astronaut ice cream is sold in many science centers and enjoyed by many people on Earth, it’s not actually sent to the space station. That said, whenever there is space in a freezer heading to orbit, the astronauts can get real ice cream onboard! 

Instead of bowls there are bags and cans

Most American food is stored in sealed bags, while most Russian food is kept in cans. 

Here’s what the crew aboard the space station enjoyed during Thanksgiving in 2015: 

Smoked Turkey

Candied Yams

Rehydratable Corn

Potatoes Au Gratin
