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...
