Radiometers Optimize Local Weather Prediction

One of the greatest dangers to aircraft—playing a role in numerous destructive and fatal accidents around the world—comes in the form of droplets of water. Clouds are made up of tiny water particles with diameters typically between 10 and 50 microns. In clean air, cloud droplets can exist in

Energy-Efficient Systems Eliminate Icing Danger for UAVs

One of the more remarkable developments in aviation in recent years has been the increasing deployment of unmanned aerial vehicles, or UAVs. Since the invention of the first UAV in 1916, these remotely—or sometimes autonomously—controlled vehicles have become invaluable tools for military reconnaissance and combat, cargo transport, search and

Rocket-Powered Parachutes Rescue Entire Planes

When Boris Popov was 8 years old, he took one of his mother’s sheets and some thread, made a parachute, climbed a tree, and jumped. The homemade chute did little to break Popov’s fall; his father took the disappointed boy aside and said, “Son, you’ve got to start higher.”

Technologies Advance UAVs for Science, Military

Greek mythology tells of the inventor Daedalus using wings of his own fashioning to escape from imprisonment on the island of Crete. In 1988, a similar adventure was launched, though in this case carbon-fiber composites, gears, and driveshafts featured instead of wax and feathers.

Inflatable Antennas Support Emergency Communication

Space exploration requires reliable and efficient communication technology. One device currently under development is the inflatable antenna. Due to several unique characteristics—it is lightweight, easy to deploy, inexpensive, and requires low storage volume—inflatable technology is especially well-suited for space applications. Without requiring mechanical actuators or human assembly, something the

Smart Sensors Assess Structural Health

The materials used to make airplanes and space shuttles do not last forever. That is why NASA frequently inspects launch vehicles, fuel tanks, crew habitats, and other components for structural damage. The timely and accurate detection of cracks or other damage can prevent failure, prolong service life, and ensure safety

Hand-Held Devices Detect Explosives and Chemical Agents

Smaller, with enhanced capabilities. Less expensive, while providing improved performance. Energy efficient, without sacrificing capabilities. Smaller, less expensive, and energy efficient—but still highly durable under some of the most extreme conditions known.

Terahertz Tools Advance Imaging for Security, Industry

On January 16, 2003, the Space Shuttle Columbia launched on mission STS-107. At T plus 82 seconds, with the orbiter rocketing upwards at 1,870 miles per hour, a briefcase-sized chunk of insulating foam broke off from the external fuel tank and struck Columbia’s left wing. During reentry on February

Sensors Provide Early Warning of Biological Threats

Originating Technology/NASA Contribution The Centers for Disease Control and Prevention (CDC) estimates there are between 4 and 11 million cases of acute gastrointestinal illnesses in the United States each year—caused by pathogens in public drinking water. The bacteria Escherichia coli (E. coli) and Salmonella have within the past few years

Robots Save Soldiers’ Lives Overseas

Originating Technology/NASA Contribution NASA intends to return people to the Moon, but this time to stay. Future plans include living quarters, scientific laboratories, a permanent lunar community, and a training ground for a future mission to Mars. Ahead of these first 21st century boots on the Moon, though, the Space Agency
