Technology developed by NASA - JUST NASA, not counting ESA or anyone else:
LED units that can ease muscle pain and arthritis and will soon be used to combat MS, complications of diabetes, Parkinsonâs.
Robot limbs - which are now being used to make more advanced prosthetics.
A new version of the  temporary artificial hearts they use to keep people alive while they are waiting for transplants. Itâs 1/10th the size. For kids. FOR KIDS.
Improved de-icing systems for aircraft.
Concrete safety grooving used to make steps less slippery.

Chemical sensors that detect metal fatigue in aircraft. To, ya know, keep them from crashing.
A device using surplus rocket fuel that can destroy land mines without setting them off.
Lots and lots of fire retardant stuff.
The breathing apparatus firefighters wear to keep them from breathing smoke.

Better ways to clean up oil spills, limiting damage to the ocean and wildlife.
Improved water purification for both people in the third world and campers.
A lot lot LOT of software, some of it used in medicine.
Structural analysis software used to design airplanes, cars, roller coasters, etc.
Powdered lubricants which greatly reduce the cost of keeping jet engines in good order, lowering the price of air tickets.
Ultrasonic monitors that can: Spot problems in railroad ties before thereâs an accident, analyze groundwater for contaminants, adjust dosage for people undergoing radiation therapy and assess internal swelling. So far. Itâs basically a tricorder.
Improved guidelines for handling seafood, juice, and dairy products.
So, shut up about how space stuff should be canceled. Because itâs benefitting ALL of us, and itâs a sideshow from the real issues.
