Circuits Enhance Scientific Instruments and Safety Devices

Originating Technology/NASA Contribution Since its founding in 1958, NASA has pioneered the use of different frequencies on the electromagnetic spectrum—including X-ray, microwave, and infrared wavelengths—to gather information about distant celestial bodies. During the 1962 Mariner 2 mission, NASA used microwave radiometers that operated in the range of 15–23 gigahertz (GHz) to assess the surface temperature of Venus and to determine the percentage of water vapor in its atmosphere.

Tough Textiles Protect Payloads and Public Safety Officers

Originating Technology/NASA Contribution Special textiles have been mission-critical components for successful space missions since the early years of NASA’s first parachutes and space suits in the late 1950s. One of the Agency’s more recognizable uses for textiles, the Mars Pathfinder airbags, provided a cushioned, instrument-friendly landing in 1997. This same technology also successfully protected the Mars Exploration Rovers when they landed on the Red Planet in 2004.

Forecasting Tools Point to Fishing Hotspots

Originating Technology/NASA Contribution Sport fishing is an uncertain pastime. Some days the fish are biting; others, not. But for captains of charter fishing boats and recreational fishermen making the most of a day off from work, returning without a catch is more than just a disappointment—it can have a financial impact as well, from wasted gas to frustrated clients taking their business elsewhere. Thanks to an evolving commercial partnership, oceanic data gathered by NASA satellites is now helping take the guesswork out of finding fishing hotspots.

Air Purifiers Eliminate Pathogens, Preserve Food

Originating Technology/NASA Contribution In order for NASA astronauts to explore the solar system, they will need to travel not just as pioneers but as settlers, learning to live off the land. Current mission needs have NASA scientists exploring ways to extract oxygen from the lunar soil and potable water from human wastes. One of the basic goals, however, will be for pioneering space travelers to learn to grow and manage their own crops. This requires the development of space-age greenhouses where astronaut farmers can experiment with harvesting large-scale food crops.

Fabrics Protect Sensitive Skin from UV Rays

Originating Technology/NASA Contribution Beginning in 1968, NASA began researching garments to help astronauts stay cool. The Agency designed the Apollo space suits to use battery-powered pumps to circulate cool water through channels in the inner layers of the garments. This led to commercial cooling vests for patients with heat control disorders (first featured in Spinoff 1979) and for workers in heat stress occupations (featured in Spinoff 1982).

Phase Change Fabrics Control Temperature

Originating Technology/NASA Contribution Since designing the first space suits in the 1950s, NASA has been interested in developing materials to keep astronauts comfortable and cool. In order to protect an astronaut from the extreme temperatures in space, engineers at Johnson Space Center created liquid-cooled garments that run water in small channels throughout the suit in what is called an active control system. However, in the 1980s, NASA began to investigate passive control strategies—fabric that could control temperature without pumped liquids—building on work by the U.S. Air Force.

Tiny Devices Project Sharp, Colorful Images Consumer, Home, and Recreation

Originating Technology/NASA Contribution Johnson Space Center, NASA’s center for the design of systems for human space flight, began developing high-resolution visual displays in the 1990s for telepresence, which uses virtual reality technology to immerse an operator into the environment of a robot in another location. Telepresence is used by several industries when virtual immersion in an environment is a safer option, including remote training exercises and virtual prototyping, as well as remote monitoring of hazardous environments. Microdisplay panels, the tiny screens that comprise the visual displays for telepresence, are also used in some electronic viewfinders for digital video and still cameras.
