6. LASIK
Technology used to track astronauts’ eyes during periods in space in order to assess how humans’ frames of reference are affected by weightlessness has become essential for use during LASIK surgery. The device tracks a patient’s eye positions for the surgeon.
7. Shock absorbers for buildings
Shock absorbers designed to protect equipment during space shuttle launches are now used to protect bridges and buildings in areas prone to earthquakes.
8. Solar cells
Out of a need to power space missions, NASA has invented, and consistently improved, photovoltaic cells, sharing the advancements with other companies to accelerate the technology.
9. Water filtration
In the 1970s, NASA developed filtration systems that utilized iodine and cartridge filters to ensure that astronauts had access to safe, tasteless water. This filtering technology is now standard.
10. Better tires
After the Goodyear Tire and Rubber Company invented the material used in NASA’s Viking Lander parachute shrouds, the company began using it in its everyday radial tires. The material is stronger than steel and adds thousands of miles of life to the tires.
