NASA’s Goddard Space Flight Center has developed a non-scanning, 3D imaging laser system that uses a simple lens system to simultaneously generate a one-dimensional or two-dimensional array of optical (light) spots to illuminate an object, surface, or image to generate a topographic profile.

Scientists at NASA’s Glenn Research Center have developed a circuit board that serves as a control and sampling interface to an inertial measurement unit (IMU). The circuit board provides sampling and communication abilities that allow the IMU to be sampled at precise intervals....

Functional and parametric degradation of microcircuits due to total ionizing dose (TID) often poses serious obstacles to deployment of critical state-of-the-art (SOTA) technologies in NASA missions. Moreover, because device dielectrics in which such degradation occurs vary from one...

The current technology for catalytic oxidation of aqueous organic contaminants at elevated temperature and pressure works well at operating conditions of 265 °F and 70 psia with effluent TOCs (total organic carbon) of less than 0.5 ppm. However, it does not perform well at the reduced...

NASA’s Kennedy Space Center (KSC) seeks to license its Advanced Fire Retardant Materials to industry. KSC’s scientists have developed processes and know-how to impart fire retardancy to common polymers such as nylons, polyesters, and...

Conventional air revitalization technology for removal of CO2, moisture, and trace organic contaminants usually involves a packed bed of sorbent pellets that can be regenerated using a concept similar to that of pressure swing adsorption (PSA). Additional heat input for thermal...

The broadband component of fan noise has grown in relevance with the utilization of increased bypass ratio and advanced fan designs. Thus, while the attenuation of fan tones remains paramount, the ability to simultaneously reduce broadband fan noise levels has become more...

Capillary columns offer challenges in gas chromatography (GC) work due to their small size and fragile nature. Typical repair techniques to join two capillary columns require cumbersome metal fittings. This solution is not applicable in...

NASA’s Langley Research Center has developed a self-latching piezocomposite actuator. The self-latching nature of this invention allows for piezo actuators that do not require constant power draw. Among other applications, the invention is well suited for use in aerodynamic control surfaces and engine inlets....

NASA’s Marshall Space Flight Center engineers have developed a new reed valve for controlling fluid flow back and forth between two chambers. The VARR valve provides two-way flow that is proportional to flow demand. As the pressure gradient builds on one side, the reed valve responds by opening an amount...

Spacecraft thermal control systems typically perform three key functions — heat acquisition, heat transport, and heat rejection — in addition to those of insulation, heat generation, and heat storage. In a typical pumped fluid-loop spacecraft thermal control system, heat is acquired from...

NASA’s Ames Research Center has developed an interactive diagnostic modeling evaluator (i-DME) tool to aid in modeling for noise and lag in the data and debugging of system models when fault detection, isolation, and recovery results are incorrect. i-DME is designed to dramatically speed up the modeling...

For a future potential radar sounder mission to small celestial bodies like comets and asteroids, it is important to understand the interaction between propagating waves and interior geophysical structures. In general, it is not easy to build a software model capable of handling...

NASA has patented a unique chemical sensor array leveraging nanostructures for monitoring the concentration of chemical species or gas molecules that is not damaged when exposed to protons and other high-energy particles over time. The nanotechnology-enabled chemical sensor array uses single...

Electron-ionized atom trapping technology is widely used in mass spectrometry and atomic clocks. The complexity of the trapping configuration operating in an ultra-high vacuum system is driven by demands for ultimate sensitivity, performance, and fundamental...

After decades of composite over-wrapped pressure vessel (COPV) development, manufacturing variance is still high, and has necessitated higher safety factors and additional mass to be flown on spacecraft, reducing overall performance. When liners are used in COPVs, they need...

Researchers at the Massachusetts Institute of Technology (MIT) have developed a system that determines exactly how much power is being used by every appliance, lighting fixture, and device in a home.

Cornell University scientists have developed an oxygen-assisted aluminum/carbon dioxide power cell that uses electrochemical reactions to both sequester the carbon dioxide and produce electricity.

NASA announced this month that its Asteroid Redirect Mission (ARM) will proceed to the next phase of design and development ahead of a planned launch in late 2021. ARM will demonstrate a solar electric propulsion system as a robotic spacecraft travels to a near-Earth asteroid (NEA). After collecting a multi-ton boulder from...

New research, developed in part by NASA’s Jet Propulsion Laboratory, could someday be used to provide first responders and firefighters with real-time temperature, gas, and danger alerts.

In a University of Maryland study, researchers at the A. James Clark School of Engineering have demonstrated that windows made of transparent wood provide more consistent natural lighting and better energy efficiency than glass.

This month, Singapore unveiled the world's first self-driving taxis. Select passengers hailed free rides last Thursday through their smartphones. While multiple companies, including Google and Volvo, have been testing self-driving cars on public roads for several years, nuTonomy, an automonomous vehicle...

An innovative underground radar technology developed at Louisiana Tech University is helping the City of Slidell in south Louisiana to identify and document underground infrastructure damage that had gone undetected in the months and years following Hurricane Katrina.
