Water is indispensable for human health and well-being. A person cannot live for more than a few days without clean, drinkable water. It is, therefore, one of the most crucial provisions astronauts need to live and work in space, whether orbiting Earth, working at a lunar base, or traveling to Mars.

A laser diode is a semiconductor-based laser used to generate analog signals or digital pulses for transmission through optical fibers or through open air. In simpler terms, it is the type of laser that scans the barcode of a product to determine its price or reads the information stored on a compact disc to play music.

Smoke inhalation injury from the noxious products of fire combustion accounts for as much as 80 percent of fire-related deaths in the United States. Many of these deaths are preventable. Smoke Mask, Inc. (SMI), of Myrtle Beach, South Carolina, is working to decrease these casualties with its line of life safety devices.

In the winter of 2009, Washington, DC, workers faced the prospect of a difficult commute due to record-setting snowfalls. But thousands of the city’s Metrorail riders found the public transportation system fully functional, thanks in part to a NASA technology invented years before.

Successfully building, flying, and maintaining the space shuttles was an immensely complex job that required a high level of detailed, precise engineering. After each shuttle landed, it entered a maintenance, repair, and overhaul (MRO) phase. Each system was thoroughly checked and tested, and worn or damaged parts replaced, before the shuttle was rolled out for its next mission.

NASA Technology

The rotors of certain helicopters can spin at speeds as high as 500 revolutions per minute. As the blades slice through the air, they flex, moving into the wind and back out, experiencing pressure changes on the order of thousands of times a second and even higher.

For 6 years prior to the retirement of the Space Shuttle Program, the shuttles carried an onboard repair kit with a tool for emergency use: two tubes of NOAX, or “good goo,” as some people called it. NOAX flew on all 22 flights following the Columbia accident, and was designed to repair damage that occurred on the exterior of the shuttle.

NASA Technology

Helicopters present many advantages over fixed-wing aircraft: they can take off from and land in tight spots, they can move in any direction with relative ease, and they can hover in one area for extended periods of time. But that maneuverability comes with costs.

After 10 months of traveling through deep space to Mars, the Phoenix Lander finally approached its destination. The last 7 minutes of the spacecraft’s 423 million-mile-journey—the entry, descent, and landing (EDL) phase—were the most critical and also the most difficult. In the history of Mars landing missions, only 5 of 13 attempts have succeeded. It would have been tragic for Phoenix to go so far yet fail to arrive safely.

NASA Technology

As NASA designs new spacecraft for its science missions and begins designs for the next generation of human spaceflight vehicles, it also works to revolutionize Earth’s airspace with safer, more efficient air vehicles. Throughout its research and development activities, NASA employs the best design tools available.
