Air Traffic Lab Answers Questions About Future Flying

The holiday season is upon us and that means crowded airports and delayed flights. Researchers at NASA's Langley Research Center are working to change that. They are conducting studies to help reshape the future of American air travel in a brand-new Air Traffic Operations Laboratory (ATOL). They are studying the Next Generation Air Transportation System, a new national airspace technology being implemented by the Federal Aviation Administration.

Foldable Material Can Support Many Times its Weight

Researchers at Drexel University and Dalian University of Technology in China have chemically engineered a new, electrically conductive nanomaterial that is flexible enough to fold, but strong enough to support many times its own weight. They believe it can be used to improve electrical energy storage, water filtration, and radio frequency shielding in technology from portable electronics to coaxial cables.

Webb Telescope’s Heart Survives Deep-Freeze Test

After 116 days of being subjected to extremely frigid temperatures like those in space, the heart of the James Webb Space Telescope, the Integrated Science Instrument Module (ISIM) and its sensitive instruments, emerged unscathed from the thermal vacuum chamber at NASA’s Goddard Space Flight Center.

Sensor Uses Radio Waves to Detect Subtle Pressure Changes

Stanford engineers have invented a wireless pressure sensor that has already been used to measure brain pressure in lab mice with brain injuries. The underlying technology has such broad potential that it could one day be used to create skin-like materials that can sense pressure, leading to prosthetic devices with the electronic equivalent of a sense of touch. In one simple demonstration they used this wireless pressure sensor to read a team member’s pulse without touching him.

3D Audio Research Helps Make Cockpit Safer

Imagine yourself in a cockpit, flying a mission, listening to a multitude of critical voices delivering vital messages, all at the same time and from the same direction. Now imagine the same environment, except that the voices are now distinct and separate. The Air Force Research Laboratory (AFRL) has developed 3D sound technology that creates a sound environment that mimics the way the human body receives aural cues, much like 3D movies create the perception that the viewer is part of the movie.

NASA Technologists Advance Next-Generation 3D Imaging

Building, fixing, and refueling space-based assets or rendezvousing with a comet or asteroid will require a robotic vehicle and a super-precise, high-resolution 3D imaging lidar that generates the real-time images needed to guide the vehicle to a target traveling at thousands of miles per hour.A team of technologists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is developing a next-generation 3D scanning lidar — dubbed the Goddard Reconfigurable Solid-state Scanning Lidar (GRSSLi) — that could provide the imagery required to execute these orbital dances.Equipped with a low-power, eye-safe laser, a micro-electro-mechanical scanner, and a single photodetector, GRSSLi will "paint" a scene with the scanning laser. Its detector will sense the reflected light to create a high-resolution 3-D image at kilometer distances — a significant increase in capability over current imaging lidars that are effective only at meter distances.Just as important, the instrument is equipped with onboard "vision" algorithms that interpret the three-dimensional image returned by the lidar. The softwar estimates location and attitude of a target relative to the lidar.SourceAlso: Learn about NASA's Asteroid Redirect Mission.
