NASA has always relied upon extreme engineering to tackle the equally
extreme challenges of space exploration, and to enable the great scientific
discoveries and feats of spaceflight that have dazzled the public over the
decades. Much of that engineering has now come back down to Earth in the form
of technological applications that touch the lives of millions, as detailed in
the U.S. space agency's annual "Spinoff" report released this month.
Spinoff tech can creep into common items such as UV-resistant swimwear
and clothing, or enter crucial systems such as third generation (3G) cellular networks. But
whatever the application, all the spinoffs draw upon their strengths as rigorously
engineered solutions driven by the unprecedented demands of space exploration.
For instance, NASA helped create a less brittle type of aerogel that
insulates space shuttle systems against the subzero temperatures of its liquid
oxygen and hydrogen fuel, maintained at -297 degrees F and -423 degrees F,
respectively. The same aerogel material has since become a part of oil pipeline
insulation, extreme weather clothing and infrared shielding for military
helicopters.
All those astronaut exercises
aboard the International Space Station have translated into
"anti-gravity" treadmills that help rehabilitate wounded soldiers, not
to mention injured athletes on professional basketball and football teams. The
G-Trainer device turns the original NASA concept on its head by adjusting air
pressure to dial down the weight on a person's lower body, rather than adding
weight to an astronaut's lower body in a low gravity space environment.
NASA engineers directly lent their talents in upgrading a robot that
helps soldiers find improvised explosives in Iraq and Afghanistan. The engineers had borrowed two MARCBots as a means of testing a futuristic wireless
network for deployment on the moon, but ended up replacing the analog camera
with a digital camera,
encrypting the controllers and video transmission against possible hacking, and
boosting the robot's movement and communications. Hundreds of newly upgraded
robots have now gone overseas to join their human wranglers in the U.S. military.
The search for life on
Mars has inspired NASA scientists to create biosensors based on nanotubes that
can detect illness-causing bacteria such as strains of E. coli. Such sensors
cut down testing times from days to just two hours, and may soon help detect
bacteria, viruses and other pathogens in everything from shower water to fruits
and vegetables.
Even early space-age technology from the days of the Apollo program's
splashdown landings continues to save human lives on Earth. Back then, NASA
engineered a stabilized life raft that could resist choppy seas and avoid
flipping over with astronauts inside during helicopter retrievals. If extreme
circumstances managed to flip the tent-like raft, water ballast helped the raft
do a somersault and right itself.
Entrepreneur Jim Givens bought the license to NASA's raft after
patenting his own similar design, and has since sold several thousand of the
inflatable rafts credited with saving the lives of over 450 people at sea. One raft
went through the most brutal of tests during Hurricane Allen in 1980, when four
men rode out 35-foot waves and wind gusts of up to 218 mph. Sometimes the raft
became submerged beneath several feet of water and flipped before righting
itself, which lead survivor Bob Harvey to comment, "We didn't feel
comfortable, but we did feel secure."
Some U.S. taxpayers may continue to grumble about a space agency that
sets lofty goals and then sometimes scrambles to meet them. But in NASA's case,
the technological journey and the act of reaching for new worlds has already
borne much fruit on Earth.
