The space race produced far more than moon landings. The intense push to solve problems in orbit, from keeping astronauts safe to building lighter equipment, generated technologies that now show up in smartphones, hospitals, mattresses, and swimming pools. NASA has profiled more than 2,000 commercial spinoff technologies since 1976, spanning categories from health and medicine to consumer goods to public safety.
Smartphone Cameras and Digital Imaging
The camera in your phone exists because of a NASA project that started in 1990. Dr. Eric Fossum was hired at NASA’s Jet Propulsion Laboratory to improve imaging technology for interplanetary missions. The existing sensors, called CCDs, were power-hungry and bulky. Fossum pivoted to a different approach, developing the first CMOS active pixel image sensor by borrowing a noise-reduction technique from CCD devices. The method takes two voltage measurements of each pixel, one without light and one with, then subtracts them to clean up the signal. The result was a smaller, more efficient sensor that could survive the harsh conditions of deep space.
In 1995, Fossum and colleague Dr. Sabrina Kemeny licensed the technology and founded a company called Photobit to develop CMOS sensors commercially. Within a few years, these sensors appeared in webcams and “pill cams,” tiny swallowable devices that photograph the digestive tract. Then the cell phone industry took off. By 2013, more than a billion CMOS sensors were manufactured annually. Today that number has grown to roughly seven billion per year. Virtually all digital still and video cameras, including every smartphone camera on the market, use CMOS technology that traces directly back to JPL.
Memory Foam
Memory foam was created in 1966 by aeronautical engineer Charles Yost, who had previously helped build a recovery system for the Apollo command module. NASA contracted Yost to improve airline seating for crash protection, and during that work he invented an open-cell polymeric foam with unusual properties: it was both highly energy-absorbent and soft. NASA’s Ames Research Center incorporated it into a new airplane seat design that distributed body weight evenly across the entire contact area, improving both crash survivability and long-flight comfort.
Originally called “slow spring back foam,” the material flows to match the contour of whatever body presses against it, then returns to its original shape once the pressure is removed. That behavior made it ideal for far more than airplane seats. It now appears in mattresses, pillows, wheelchair cushions, helmet liners, and shoe insoles. The global memory foam mattress market alone is worth billions of dollars, all rooted in a NASA contract to make airplane seats safer.
Infrared Ear Thermometers
The ear thermometers used in hospitals and homes came from the same science NASA uses to measure the temperature of distant stars. Astronomers gauge a star’s heat by measuring the infrared energy it emits. In the 1990s, Diatek Corporation partnered with JPL to apply that principle to the human eardrum. The result was the Diatek Model 7000 aural thermometer, which weighed just eight ounces and could read a patient’s temperature in under two seconds. Before this, getting an accurate temperature reading meant waiting several minutes with a mercury thermometer under the tongue. The infrared approach was faster, more hygienic, and especially practical for young children.
Programmable Insulin Pumps
Modern insulin pumps owe key components to two separate space programs. The miniaturized fluid control system at the heart of early programmable pumps was originally developed for life-detection experiments aboard NASA’s two Viking spacecraft, which landed on Mars in 1976. Those experiments needed to handle tiny volumes of fluid with extreme precision in a device small enough to fit on a lander. That same micro-fluid technology was adapted to deliver precise doses of insulin inside the human body.
The pumps also use a miniature two-way communications system based on space telemetry, the same technology that allows mission controllers to monitor a spacecraft’s systems from millions of miles away. In an insulin pump, this telemetry sends signals from the implanted device with operating information like insulin usage and pump performance, giving patients and doctors a real-time window into how the device is functioning.
Noise-Canceling Headsets
The lightweight headsets used in call centers, aviation, and everyday Bluetooth earbuds trace their lineage to NASA’s Mercury and Apollo programs. ITT Labs delivered a radio transceiver to NASA that happened to include a headset made by Pacific Plantronics. When astronaut Wally Schirra saw the lightweight design, he asked whether it could be built directly into his helmet. That request kicked off a collaboration between Plantronics and NASA focused on noise-canceling microphones using dual miniature transducers, tiny components that convert sound waves into electrical signals while filtering out background noise.
The improved headset was developed for the Faith 7 Mercury mission and continued through Gemini, Apollo, and Skylab. Neil Armstrong’s “one small step” transmission traveled from this headset technology to Mission Control and then to the world. Plantronics went on to build its entire commercial product line on the expertise it developed designing mission-critical audio equipment for NASA.
Water Purification
Keeping drinking water safe inside a sealed spacecraft required a purification method that worked without heavy chemical systems. For the Apollo program, NASA developed silver ion purification, which releases small amounts of silver into water to destroy viruses and waterborne bacteria without adding chlorine or other chemicals that could produce harmful byproducts in a closed environment.
After Apollo, the technology moved into civilian use. It was first adapted to sanitize swimming pools, offering a gentler alternative to heavy chlorination. From there it expanded to industrial applications: cooling towers at General Motors plants, amusement park water systems, ice manufacturing facilities, and closed-loop process cooling systems. The same basic principle, using silver ions to kill pathogens, now operates in water treatment contexts around the world.
The Broader Pattern
What connects all of these technologies is a common origin story. Space imposes extreme constraints: limited power, limited weight, limited space, zero room for failure. Engineers solving those problems produced solutions that turned out to be exactly what civilian life needed too. A sensor that could survive interplanetary radiation also happened to be small and efficient enough for a phone. A foam designed to protect pilots in a crash also happened to make a better mattress. NASA’s spinoff catalog covers more than 2,000 technologies across energy, transportation, public safety, and industrial productivity, and new ones are still being added every year. The space race ended decades ago, but its engineering legacy keeps quietly running in the background of daily life.
