NASA in your house: 10 inventions that revolutionized everyday life

Image: NASA

You probably never realized that NASA, the same agency that revolutionized space travel back in the sixties and seventies, is also responsible for the microchips in your favorite electronics, the alarm that warns you of fire, the sensor that lets you take a quick selfie on your phone , among other everyday inventions. Ready to rediscover them?

1
Microchip

Before microchips, computers relied on glass vacuum tubes that were large, fragile, and too heavy for a spacecraft. To solve this, NASA, during the moon race in the 60s, made a massive bet on a new invention called the integrated circuit, which packed complex electronics onto a tiny sliver of silicon. While these early "microchips" were very expensive and unproven, the Apollo program committed to buying over 60 per cent of all chips made in America. This guaranteed market gave companies like Fairchild Semiconductor, a Californian technology company, the support they needed to perfect the tech and lower the costs. NASA's support as the principal customer for microchips helped the digital revolution happen much sooner than expected. Today, that technology is within almost every electronic device, from the microwave to the laptop.

Smoke Detector

They are among the most important safety tools in our homes, and most people don't know their modern version was shaped for a 1970s space mission. Truth is, the first electric smoke detector was invented in the 1930s by Swiss physicist Walter Jaeger, almost by accident, while working on a gas detection device. Early smoke detectors worked, but they were often too expensive or sensitive for everyday homes.

In the 1970s, NASA teamed up with Honeywell Corporation, a North Carolina-based technology and manufacturing company, to improve the design for Skylab, the first U.S. space station. Astronauts needed an alarm that could detect a real fire without constantly reacting to harmless gases inside the station's tight living quarters. So they added an adjustable sensitivity and long-lasting backup batteries, creating the "nuisance-free" smoke alarm we still use in our homes today.

Cell Phone Camera

In the 1990s, NASA's Jet Propulsion Laboratory needed to shrink cameras down so they could fit on small spacecraft without draining the battery. Engineer Eric Fossum invented the image sensor, which put all the camera's functions onto a single tiny chip , making cameras much smaller and more efficient than ever before.

In 1995, Fossum founded the company Photobit to bring this space-age sensor to the commercial market. Today, this technology allows smartphones to take high-quality photos while staying thin enough to fit almost everywhere, making it the most used camera tech in the world.

Cordless Tools

In the early 1960s, Black & Decker developed the first cordless electric drill for commercial use. NASA later recognized the potential and, in 1965, contracted Black & Decker to adapt and refine this technology for the Apollo program, creating a lightweight, battery-powered drill that could operate in the moon's harsh environment and in zero gravity.

But that wasn't all. To make it work for space, they had to improve a specialized motor and smart software that didn't drain the battery too fas t. By the late 1970s, the Dustbuster, the first cordless vacuum, was created, along with the improved battery-powered tools we still rely on today.

Memory Foam

Have you ever wondered why your mattress is smart enough to remember its original shape? Memory foam is a type of high-density polyurethane foam that softens when heated and under pressure. When you lie down on it, it molds to your body, and when you get up, it slowly returns to its original shape. That's what the "memory" part is about.

NASA developed memory foam in the 1960s to improve seat cushioning and crash protection for airline pilots and passengers, and later adapted it to protect astronauts from "G-forces" during space travel . As it reacted to body heat, the foam softened and molded perfectly to a person's frame, absorbing shock on impact. It took about twenty years to reach the public; the first memory foam mattress didn't hit the market until the early 1990s by companies like Tempur-Pedic and Fagerdala World Foams.

Sneaker Air Cushioning

Ever wondered how Nike Airs were created? The truth is that the bounce in many modern sneakers is actually a product of the space industry. A NASA engineer named Frank Rudy, who worked on the Saturn and Apollo rocket engines, was introduced to a process called blow rubber moulding, used to create sealed, pressurised membranes for aerospace applications. He realized this same process could be used to trap gas inside a shoe sole.

In 1977, he brought this idea to Nike, and this led to the creation of the Nike Air Tailwind in 1978, the first shoe to feature this space-inspired cushioning. Today, air-cushioned soles are a standard, using the same aerospace tech to protect joints in every step.

7
Water Filters

In 1963, NASA faced an important challenge for the Apollo program: keeping drinking water pure for long missions without using heavy chemicals. To solve this, they pioneered a system that used silver ions to kill bacteria and activated carbon to remove pollutants. This allowed astronauts to have clean water stored for weeks.

By the 1970s, NASA shared this technology with the public, leading to the creation of companies like Aquaspace. These days, this same silver-ion and carbon tech is used inside household water pitchers and refrigerator filters to remove contaminants.

8
Scratch-Resistant Lenses

In the 1970s, NASA scientist Ted Wydeven of the Ames Research Center was working on a spacecraft water purification system when he coated a filter with a thin plastic film using an electric discharge of an organic vapor. The result protected the plastic surfaces of aerospace equipment from scratching.

This film made plastic up to ten times more scratch-resistant than earlier materials. In 1983, Foster-Grant licensed the technology and used it to produce scratch-resistant lenses for sunglasses and eyeglasses, introducing space technology to our daily lives.

Ear Thermometer

NASA technology and modern healthcare are surprisingly close. It turns out that the same tech used to measure the heat of distant stars is now in our medicine cabinet . In the 1980s, NASA developed special infrared sensors because scientists evidently couldn't place a physical thermometer on a planet millions of miles away. These sensors worked by "reading" invisible heat energy from a distance.

By 1991, a medical technology company called Diatek teamed up with NASA to bring this space tech into daily medicine. They realized the human eardrum also emits infrared heat, and that could work as a perfect window to measure our body temperature. This partnership resulted in the first handheld ear thermometer, making fever checks much more comfortable and easier.

10
Super Soaker

You probably assumed that the world's most famous water gun was created in a toy lab. It was actually invented in the home workshop of NASA engineer Lonnie Johnson. In 1982, while working on a new heat pump that used water instead of refrigerant, a nozzle he was testing shot a powerful stream across his bathroom.

Johnson realized its toy potential and licensed his "Power Drencher" design to the toy company Larami. It was renamed to the Super Soaker in 1991, and it uses the same air-pressure principles Johnson applied to spacecraft systems.

America’s past

Grab a root and learn some interesting Civil War Lingo!

Image: Erika Wittlieb

The Civil War wasn’t just cannons and cavalry. It was also a time when soldiers invented a whole dictionary. Some terms were funny, some grim, and others quite practical. Today, we’ll peek into the soldier’s vocabulary , from "fresh fish" rookies to the itchy reality of "graybacks." So pull up a chair, maybe grab a root, and let’s take a trip through the words that marched alongside history.

1
Fresh fish

Image: Chris Chow

If you were new to the army , you were "fresh fish." Veterans spotted them a mile away, wide-eyed, uniforms still smelling like the depot, and not yet hardened by camp life. They got teased, trained, and sometimes tricked. Of course, every seasoned soldier once wore the "fresh fish" badge, so the teasing came with a knowing grin.

2
Grab a root

Image: Lars Blankers

Dinner time in camp could mean beans, hardtack, or, if you were lucky, a potato. Asking someone to "grab a root" was soldier shorthand for "let’s eat." Potatoes were cheap, filling, and easy to cook over a campfire.

3
Sawbones

Image: Piron Guillaume

Medical science in the 1860s wasn’t exactly what we call gentle. Army surgeons were nicknamed "sawbones," partly for their skill with amputations, a normal procedure during wartime. It wasn’t always fair, since many doctors were dedicated and resourceful, but the name stuck.

4
Graybacks

Image: Scott Umstattd

Ask a soldier about "graybacks" and you might get two very different answers. One was lice, the pest that thrived in crowded camps. The other was a nickname Union troops used for Confederate soldiers . Either way, it wasn’t a compliment.

5
Bonnie Blue Flag

This was the hit song of the Confederacy , praising the states that left the Union. The "Bonnie Blue Flag" itself showed a single white star on a blue field, the first banner of the Confederacy. The song’s lively chorus made it a favorite at rallies, campfires, and any place soldiers needed a boost of spirit.

6
Furlough

Image: Stijn Swinnen

A furlough was a soldier’s golden ticket home , even if only for a short while. The paperwork described the soldier’s looks, regiment, and exact return date, plus a stern warning about being labeled a deserter if he didn’t show up on time.

7
Housewife

Image: Annie Spratt

Every soldier carried a "housewife," though it wasn’t a person; it was a sewing kit . Packed with needles, thread, and spare buttons, it kept uniforms in one piece. With supply lines stretched thin, a quick stitch could mean the difference between looking like a soldier or a scarecrow.

8
Insult

Image: Aleksey Kashmar

On a Civil War battlefield, an "insult" wasn’t words, it was a sudden attack on a fortified position. The idea was to strike before the defenders could react. Success could turn the tide of a fight, but failure usually meant heavy losses. It was risky and brutal.

9
Kepi

Image: Jen Theodore

The kepi was the go-to cap for Union soldiers, with a flat circular top and short visor . It was light, practical, and easy to make, so it became part of the classic Civil War look. Confederate soldiers sometimes wore them too, but it was a Union signature item.

10
Ordnance

Image: Rick Lobs

If it was in any way designed to make the enemy’s day worse, it was "ordnance." This covered everything from muskets to cannonballs . Armies guarded their ordnance like gold, since running low meant fighting at a disadvantage.

11
Skirmish

Image: Carol Highsmith's America

Not every fight was a massive battle. A "skirmish" was a smaller clash , often between scouting parties or outposts. Quick, unpredictable, and sometimes over in minutes, skirmishes kept soldiers on edge and commanders guessing what the enemy was really up to.

Cities as movie characters: have you seen these 10 great examples?

Image: Teitur Hansen / Andrew Adams

Our country produces countless quality movies every year, drawing inspiration from a vast range of places, people, and events. One of the most classic sources of inspiration is the array of wonderful cities scattered across the nation. For example, Gone With the Wind wouldn’t be the same if set anywhere other than Atlanta, and the same goes for movies like Rocky , set in Philadelphia, or Casino , in Las Vegas. These movies take us on journeys through cities that are as much characters as the actors themselves. Let’s take a look at 10 films that are closely tied to the cities that inspired them.

1
Atlanta - "Gone with the Wind"

Image: Brad Huchteman

We can’t think of a film that captures the South quite like Gone with the Wind , can you?

In this sweeping epic that tells the story of love, war, and survival during the Civil War, Atlanta plays a crucial role as the backdrop for Scarlett O’Hara’s turbulent life and relationships, especially with Rhett Butler, played by the great Clark Gable.

The brilliance of the film and Scarlett’s story, iconically portrayed by Vivien Leigh, mirrors the history and transformation of Atlanta itself, a city that goes from bustling to ravaging due to war.

If you’re from Atlanta, cheer proudly—your city made it to the top of this list!

2
St. Louis - "Meet me in St. Louis"

Image: Chris Hardy

Some movies make us wonder: Which came first—the city’s popularity or the movie’s? In any case, we can’t deny that some movies and cities share equal popularity, regardless of which one started it. That is the case of Meet Me in St. Louis a charming, feel-good musical that transports us to turn-of-the-century St. Louis.

The film follows the Smith family as they experience love, heartbreak, and the excitement of the 1904 World’s Fair. The one and only Judy Garland stars as Esther, and her unforgettable performance of "Have Yourself a Merry Little Christmas" makes this film a holiday favorite. St. Louis shines as the backdrop, from the family’s cozy home to the city’s festive atmosphere, giving the story an old-fashioned warmth.

3
New York City - "12 Angry Men"

Image: Jason Briscoe

Movies that were inspired by The City that Never Sleeps? Well, that could be an article in itself. From The Godfather to Taxi Driver to Do the Right Thing , the list is truly endless. But for the sake of this article, we’ve committed to only one and that’s 12 Angry Men .

This classic courtroom drama follows twelve jurors as they decide the fate of a young man accused of murder. Set in the heart of New York City, 12 Angry Men contrasts the pressure and intensity of city life, against the claustrophobic jury room, where tempers flare. The cast is led by Henry Fonda, who plays a calm and reasoned juror who slowly persuades the others to see the case in a different light.

Much like living in this city, watching the film makes you feel every emotion possible!

Washington, D.C. - "All The President’s Men"

Image: Harold Mendoza

Washington, D.C., is the capital of our country, and when you think of it, you think of politics, prominent figures, and government matters. Combine that with the Watergate scandal—an event that shook America’s political class to its core—and you have the foundation for a compelling movie.

Based on a true story, All the President’s Men follows Washington Post journalists Bob Woodward and Carl Bernstein as they investigate political corruption at the highest level. Washington, D.C., serves as the backdrop to a story that offers a front-row seat to the unraveling of a presidency. Robert Redford and Dustin Hoffman deliver standout performances as the determined reporters who refuse to give up.

Washington, D.C., is the perfect setting for this high-stakes thriller.

5
Philadelphia - "Rocky"

Image: Jonathan Gong

"Every champion was once a contender who refused to give up," said Rocky, and with that, Philadelphia became forever associated with persistence, resilience, and, of course, boxing.

Philadelphia is inseparable from Rocky , the story of a down-and-out boxer who gets the chance of a lifetime. Sylvester Stallone stars as Rocky Balboa, whose iconic run up the steps of the Philadelphia Museum of Art is as legendary as the movie itself. The city’s blue-collar spirit is on full display, making it the perfect backdrop for Rocky’s fight for respect and glory. Philly becomes a symbol of perseverance, where dreams are chased, and grit is rewarded.

Honorable mentions: The Wrestler (2008), The Sixth Sense (1999), and Blow Out (1981) also showcase Philly’s diverse storytelling.

6
Miami - "Scarface"

Image: aurora.kreativ

What do you think of when you think of Miami? For us, it’s not just the beaches or the Everglades—it’s Tony Montana. And not because Miami is exactly dangerous, but because Scarface and its unforgettable anti-hero have been living rent-free in our minds ever since it premiered.

If you’ve seen it, you know it: this film takes us on a wild ride through the rise and fall of Tony Montana , played by Al Pacino in one of his most iconic roles.

As for the city, Miami—with its sunny beaches and drug-fueled underworld—serves as the perfect backdrop for Tony’s relentless climb to power. The city itself becomes a symbol of both opportunity and excess, where fast cars, palm trees, and glowing lights mask a darker reality. While we don’t think this is an accurate representation of this beautiful city, we can’t deny it was a supreme one!

7
Chicago - "Home Alone"

Image: Fineas Anton

Chicago has seen some incredible productions, from the namesake musical to _The Untouchables_—each capturing the spirit of this dynamic city in its own way. But since we’ve already discussed crime-related films, let’s dive into comedy. And if we combine Chicago and the comedy category , nothing beats Home Alone .

In the movie, we follow Kevin, a kid left behind in the city while his family heads off on a holiday trip. Alone and loving it, Kevin, played by Macaulay Culkin, soon has to defend his home from two not-so-bright burglars, portrayed by Joe Pesci and Daniel Stern.

The cozy suburban setting is perfectly snowy and festive, making it feel like the ultimate holiday getaway. Well, that is if you can ignore the burglars!

8
Detroit - "True Romance"

Image: Alex Brisbey

Movies that mention Elvis Presley? Yes, please! This movie has action, an Elvis fan, and a great city—Detroit—and we have Quentin Tarantino to thank for it.

True Romance takes viewers on a wild ride through Detroit, following Clarence, played by Christian Slater, and Alabama, played by Patricia Arquette, as they try to outrun the mob.

The streets of Detroit and the industrial vibe of the city perfectly match the film’s fast-paced, chaotic energy. It’s a Tarantino film, one is expecting this kind of rhythm.

It’s a love story wrapped in a crime drama, with a dash of dark humor and a lot of action. The Motor City isn’t just a backdrop, we can consider it a character that adds to the rawness of the film.

9
San Francisco - "Mrs. Doubtfire"

Image: Josh Hild

10

San Francisco has that heartwarming spirit, and the story of a father who would do anything for his kids perfectly matches that vibe—it’s highly relatable, don’t you think?

In Mrs. Doubtfire , we follow Robin Williams although he’s not in his usual clothes. He dresses up as an elderly British woman, Mrs. Doubtfire, to work as a nanny and stay close to his kids.

The hilly streets of the City make it a perfect background for all the shenanigans going on in the family. From the classic foggy mornings to the iconic scene on the Golden Gate Bridge, the movie takes us around San Francisco with a perfectly matched playful spirit.

11
Las Vegas - "Casino"

Image: David Lusvardi

Quite appropriate, don’t you think? When you think of Vegas, you think of card games, gambling, a nice drink in your hand, and a comfortable hotel to return to.

In the movie Casino, we are taken into the neon lights and dark underbelly of Las Vegas, where the lives of casino operators and the mob intertwine . Directed by Martin Scorsese, the film stars Robert De Niro, Sharon Stone, and Joe Pesci in a dazzling, dangerous story about power, money, and, of course, betrayal.

Las Vegas, with its unique and vibrant spirit, is the perfect setting for this story in which stakes are high and risks even higher. Have you watched it?
