Aerospace gives people a special feeling of "high cold", which is an advanced fighter, a majestic space station, which cannot be seen, touched, or used by ordinary people.
A few days ago, the well-known US website “GOBankingRates” took stock of 25 technologies from the National Aeronautics and Space Administration (NASA) in our daily life, all of which we “snap and wear”. They come from distant sky, but they are convenient for our daily life.
Food: baby milk powder, freeze-dried fruit, food safety packaging
Currently, more than 90% of infant formula in the United States contains microalgae. Originally a product of NASA research, the aim of the study was to test the potential use of algae as a “recycling agent for oxygen in space travel”.
Freeze-dried fruit is a common snack. But NASA's goal of developing freeze-drying technology is to make the fruit in the “Apollo” task easier to carry, which can maintain 98% nutrition at 20% quality.
NASA To ensure safe quality control of space flight food development, food safety packaging has become a food industry standard to protect food safety for consumers around the world.
Life: Memory foam mattress, scratch-resistant lens, UV-resistant sunglasses, cordless vacuum cleaner, Nike air cushion sports shoes, space blanket, ski boots
The comfortable memory foam mattress can fully fit the human body and relieve stress, which is a must for many families. The memory foam was not originally used for mattresses. It was originally developed by NASA to cushion the impact of spacecraft landings on astronauts.
The scratch-resistant lens has a longer life than ordinary glass. In fact, the scratch-resistant coating is a “by-product” that NASA's Jet Propulsion Laboratory (JPL) inadvertently discovered when studying aerospace diamond hard coatings.
In the 1980s, two scientists from JPL developed a welding spectacles that absorbed, filtered, and scattered the glare from the welding process. Later, the technology was widely used in UV protection sunglasses.
Originally, Black&Decker was commissioned to develop a portable device for extracting samples from below the lunar surface for the “Apollo” and “Gemini” missions. This technology has been improved to become a “cordless vacuum cleaner”.
Nike air-cushion sneakers use NASA former engineer M. Frank & middot; Rudy won the "Blow Molding Rubber Forming" technology patent, the original application of this technology is the spacesuit.
Insulation and insulation of the space blanket are essential for survival in the wild and marathon. But it was originally developed by NASA to protect spacecraft and astronauts at low temperatures.
In addition, NASA's technology in the joints of space suits has been improved and used in ski boots to improve athletes' ability to control skiing.
Home: swimming pool purification system, household insulation materials
To combat extremely low space temperatures, NASA uses aluminized polyester to create an insulation called “radiation barrier”. According to JPL, aluminized polyester is now used in most household insulation materials.
In the 1960s, NASA developed an electrolytic silver iodide filter to provide astronauts with clean drinking water, which is now widely used to purify swimming pools.
Travel: Aircraft de-icing system, precision GPS, road anti-skid trough, better tires
According to NASA's technology transfer program, civil aircraft can fly in cold weather, mainly thanks to a thermal de-icing system called Thermawing developed by NASA.
Precision GPS technology developed by JPL is installed in many mobile phones, and its data comes from the JPL global GPS receiver network. Even if you don't have a wireless connection, you can still use GPS positioning on your phone.
NASA's Langley Research Center developed anti-skid technology to prevent aircraft from accidents on wet runways. Later, the technology was widely used on highways.
In the 1970s, Goodyear developed a new tire material for the NASA & quot; Pirates Mars probe for the parachute system. The technology was later used to improve ordinary tires, increasing their lifespan by 10,000 miles.
Electronics: mobile phone cameras, laptops, high-power solar cells, wireless headsets, mice, CAT scanners
In the 1990s, NASA asked JPL scientists to create a tiny camera that could be mounted on a spacecraft while maintaining the quality of the camera. JPL says that one-third of mobile phone cameras now use this technology.
According to the Smithsonian National Air and Space Museum, “Grid Compass” was the world's first laptop and was first used in space shuttle missions in 1983, one of NASA's inventions.
The crystalline silicon solar cells used in the home were originally derived from the lightweight solar energy system developed by NASA's Environmental Research Aircraft and Sensor Technology Alliance for electric aircraft.
NASA developed wireless headsets for astronauts to facilitate communication. Now this technology has entered thousands of households.
According to JPL, a NASA researcher developed a computer mouse in the 1960s to allow users to operate on a computer screen, making the computer more interactive.
JPL originally developed a CAT scanner that scans aerospace components for advanced digital images to detect flaws. Now, it has become a commonly used medical instrument.
Healthcare: implantable cochlear, invisible dental appliance, ear thermometer
Kennedy Space Center engineer Adam · Kieser developed his early manual implanted cochlea using his experience in electrical, acoustic and vibration sensor systems in the space shuttle program, using electrical pulses instead of sound amplification techniques.
Invisible dental appliances are more aesthetically pleasing than traditional metal appliances, made of transparent polycrystalline alumina, originally developed by NASA to track heat-seeking missiles.
Nowadays, many parents use ear thermometers to measure the body temperature of sick babies or young children. JPL says the thermometer uses infrared anatomy invented by NASA and Dietek.
These 25 technologies, there is always one you have seen, touched, used. Aerospace technology can't be used only in high-altitude space. After landing, it will improve our quality of life. This is one of the driving forces for human beings to explore and fly higher and farther.
