Scratch-resistant lenses were developed by NASA by applying a diamond-like lubricating coat over plastic lenses. This application was originally used in the space program in a "dual ion-beam bonding process." Today, the coating is still used on hard resin plastic used in most eye glasses that people wear every day.
Humans need food, and astronauts in space are no exception. To keep the astronauts food fresh NASA adopted the practice of freeze-drying food. This process proved effective on food and allowed for extended manned space flights such as the Apollo flights. In the process, the food is frozen and then most of the moisture is removed from the frozen object. The moisture is removed by sublimation; it turns into a vapor before a liquid. The process works best on liquids, thin slices of meat, and small objects like peas.
Technology originally developed for boots that were worn on the moon, now have been applied to athletic shoes in the mid-sole section. The technology improves shock absorption, stability, and motion control. The sneaker industry has also used this technology to try to brainwash consumers into believing they need this commodity, creating a social spin-off of its own.
CAT & MRI Technologies
The entire purpose of the early Apollo missions were to choose a suitable landing ground for the first man on the moon. To do this, they needed technology that could photograph the moon's surface. NASA created this technology, and from it scientists developed Computer-Aided Topography (CAT) and Magnetic Resonance Imaging (MRI) technologies. Today, CAT scanners and MRIs are used in hospitals world-wide.
As with athletic shoes, part of the astronauts' outfits were adapted for non-space purposes. This feature of the astronauts' outfit was the suit itself. The suit was designed to keep astronauts at a comfortable temperature while working in space. Today, the same concept is behind... [continues]
