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.

9

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.

Tiger salamander

Image: Anastasia Pirri

Meet the tiger salamander—one of the largest terrestrial salamanders in North America. While its size is certainly impressive, the tiger salamander also has other traits that make it stand out. Take its appearance, for example: its dark brown body with bright yellow blotches resembles tiger stripes, which is why it has such a peculiar name. But there's more! Unlike many other salamanders, this one spends much of its time underground, using its large, powerful limbs to dig.

Fun fact: Some states, like Colorado and Kansas, have named it their official state amphibian!

2

Eastern Hellbender

Although the tiger salamander is impressively large, another salamander stands out for its huge size: the Eastern Hellbender.

Cryptobranchus alleganiensis alleganiensis is its scientific name (quite a mouthful, right?). It holds the title of the largest salamander in North America. In fact, it's sometimes nicknamed "snot otter" due to its large body and the slippery texture of its skin.

3

Amphiuma

Image: Wolfgang Hasselmann

When you first see this creature, you might mistake it for a snake or an eel. But it's actually an amphibian—more specifically, an aquatic salamander known as the amphiuma. Its appearance, let’s just say, isn’t exactly what most would call "cute."

This unusual amphibian can grow up to 3 feet long! And while not immediately noticeable, it has tiny legs with only one, two, or three toes, depending on the species. Its limbs aren't very useful, but they do make the amphiuma look just a bit creepier.

4

Colorado River Toad

Image: Crystal McClernon

The Colorado River Toad may not be the cutest or most dazzling creature out there, but it's certainly one of the most fascinating. Native to the southwestern United States, this amphibian is one of the largest toads in North America, but what sets it apart isn't its size. So, while it may look slow and harmless, this toad is capable of releasing a dangerous, highly psychoactive toxin that acts as a defense mechanism and can be fatal to many species, including dogs.

5

Common Mudpuppy

Now, it's time for an amphibian whose cuteness is one of its most distinctive features; even its name reflects that! We're talking about the Common Mudpuppy, an aquatic salamander that inhabits streams, rivers, ponds, and lakes. It's also one of the few salamanders that remain fully aquatic throughout their entire life. And that’s precisely why it sports a pair of large, red external gills on the sides of its head, giving it an almost 16th-century European look!

6

Gray Tree Frog

Image: Aurora K

The small Gray Tree Frog inhabits the forests and woodlands of the eastern United States. And while it's true you might find it on trees and plants, its nickname isn't entirely accurate when it comes to color. Yes, it can be gray, but this amphibian has the ability to change its color to blend in with its surroundings! It also has another superpower: the ability to survive freezing temperatures. By producing a natural antifreeze, it protects its organs during cold conditions that most of us couldn’t begin to handle.

7

Spotted Salamander

Image: Kristina Kutleša

As its name suggests, what distinguishes the Spotted Salamander is its shocking look. But beware, its mottled appearance isn't just for show. It also acts as a warning to ward off predators! If you've ever seen one in the wild, consider yourself lucky because although it’s fairly widespread, this salamander spends most of its time underground.

8

Pacific Giant Salamander

Image: wallace Henry

If you venture into the mountainous regions of the Pacific Northwest, you might come face-to-face with the Pacific Giant Salamander, one of the largest terrestrial salamanders in North America.

Reaching up to 14 inches in length, this amphibian is striking to see—but it’s even more surprising when you hear it. That’s right: unlike most of its kind, the Pacific giant salamander can make audible barking sounds!

9

Barking Tree Frog

Image: José M. Alarcón

We have a contestant that could go head-to-head with the Pacific Giant Salamander in a barking contest: the aptly named Barking Tree Frog.

Let’s just say the frog’s striking features are perfectly summed up by its name. In states like Florida, Georgia, and South Carolina, you can find this little amphibian calling from the treetops or near freshwater shores.

10

Dusky Gopher Frog

Finally, we have the most mysterious and elusive of all: the Dusky Gopher Frog. As one of the rarest frog species in the U.S., the Dusky Gopher Frog is incredibly elusive and critically endangered, with fewer than 200 individuals left in the wild. The dusky frog spends most of its life hidden underground and only comes out during the mating season.
