Athletes Go for the Gold with NASA Spinoffs

NASA technology tends to find its way into the sporting world more often than you’d expect. Fitness is important to the space program because astronauts must undergo the extreme g-forces of getting into space and endure the long-term effects of weightlessness on the human body. The agency’s engineering expertise also means that items like shoes and swimsuits can be improved with NASA know-how.

As the 2024 Olympics are in full swing in Paris, here are some of the many NASA-derived technologies that have helped competitive athletes train for the games and made sure they’re properly equipped to win.

The LZR Racer reduces skin friction drag by covering more skin than traditional swimsuits. Multiple pieces of the water-resistant and extremely lightweight LZR Pulse fabric connect at ultrasonically welded seams and incorporate extremely low-profile zippers to keep viscous drag to a minimum.

Swimsuits That Don’t Drag

When the swimsuit manufacturer Speedo wanted its LZR Racer suit to have as little drag as possible, the company turned to the experts at Langley Research Center to test its materials and design. The end result was that the new suit reduced drag by 24 percent compared to the prior generation of Speedo racing suit and broke 13 world records in 2008. While the original LZR Racer is no longer used in competition due to the advantage it gave wearers, its legacy lives on in derivatives still produced to this day.

Trilion Quality Systems worked with NASA’s Glenn Research Center to adapt existing stereo photogrammetry software to work with high-speed cameras. Now the company sells the package widely, and it is used to analyze stress and strain in everything from knee implants to running shoes and more.

High-Speed Cameras for High-Speed Shoes

After space shuttle Columbia, investigators needed to see how materials reacted during recreation tests with high-speed cameras, which involved working with industry to create a system that could analyze footage filmed at 30,000 frames per second. Engineers at Adidas used this system to analyze the behavior of Olympic marathoners' feet as they hit the ground and adjusted the design of the company’s high-performance footwear based on these observations.

Martial artist Barry French holds an Impax Body Shield while former European middle-weight kickboxing champion Daryl Tyler delivers an explosive jump side kick; the force of the impact is registered precisely and shown on the display panel of the electronic box French is wearing on his belt.

One-Thousandth-of-an-Inch Punch

In the 1980s, Olympic martial artists needed a way to measure the impact of their strikes to improve training for competition. Impulse Technology reached out to Glenn Research Center to create the Impax sensor, an ultra-thin film sensor which creates a small amount of voltage when struck. The more force applied, the more voltage it generates, enabling a computerized display to show how powerful a punch or kick was.

Astronaut Sunita Williams poses while using the Interim Resistive Exercise Device on the ISS. The cylinders at the base of each side house the SpiraFlex FlexPacks that inventor Paul Francis honed under NASA contracts. They would go on to power the Bowflex Revolution and other commercial exercise equipment.

Weight Training Without the Weight

Astronauts spending long periods of time in space needed a way to maintain muscle mass without the effect of gravity, but lifting free weights doesn’t work when you’re practically weightless. An exercise machine that uses elastic resistance to provide the same benefits as weightlifting went to the space station in the year 2000. That resistance technology was commercialized into the Bowflex Revolution home exercise equipment shortly afterwards.

Why do you need your earbuds to have a wire so badly?

I am assuming this is about a post I reblogged like six months ago when I went off on forced technological enshitification and the slow erosion of consumer options. But sure, I'll bite.

Why do I "need" my earbuds to have a wire? I dunno, Anon, maybe I:

Don't want to have to worry about recharging my earbuds.

Don't want my earbuds to be even easier to lose.

Don't want my earbuds to need separate accessories that are as easy to lose as the earbuds.

Prefer to have bluetooth turned off on my devices for security and safety reasons.

Like being able to seamlessly plug my earbuds into my computer, my MP3 player, or any other device with a headphone jack.

Don't want to spend 50 dollars on decent wireless earbuds when I can do all the above things with a pair of solid earbuds that cost me like $12 during the Obama administration.

Don't care about what kinds of headphones or earbuds people wear but don't like what it says about our society when other people apparently care what kind of earbuds I'm wearing so much they have send an Anonymous ask to interrogate me about it.

And I guess, more abstractly, because fuck Apple. That's why.

Happy New Year 2024 from Korea.

Year of the 🐲🐉!

To be fair, a lot of goofy-sounding rocketry/aerospace terminology has a legitimate nomenclatural role beyond just being silly euphemisms.

"Unplanned rapid disassembly", for example, exists as the necessary counterpart to planned rapid disassembly: sometimes a rocket is legitimately supposed to fall apart or blow up, so you need a specific term to emphasise that it wasn't supposed to do that.

Similarly, "lithobraking" was coined by analogy with aerobraking (shedding velocity via atmospheric friction) and hydrobraking (shedding velocity by landing in water), and it does have some intentional applications; the Mars Pathfinder probe, for example, was deliberately crashed into the Martian surface while surrounded by giant airbags, and reportedly bounced at least 15 times before coming to rest.

(That said, aerospace engineers absolutely do use these terms humorously as well, because engineers are just Like That.)
