Current science objectives, such as high-contrast imaging of exoplanets, have led to the development of highorder adaptive optics (AO) systems possessing several thousand deformable mirror (DM) actuators. These systems typically rely on integrator-based control...

NASA Langley Research Center has developed a novel spectral analysis system that provides rapid multispectral analysis and imaging in a miniaturized system design. Typical spectrometers make use of linear gratings with linear slits or charge-coupled device (CCD) arrays to separate and detect...

Utilizing the full mechanical capabilities of individual nanotubes is a primary research goal in nanotube reinforced nanocomposite materials. Practical use of these nanomaterials requires creating stable and strong linkages between nanotubes without...

NASA Langley Research Center has developed a novel negative dielectric constant material based on ion-conducting materials. A negative dielectric constant material is an essential key for creating metamaterials, or artificial negative index materials (NIMs). NIMs have generated...

Thrust chambers have historically been difficult to manufacture. They require extensive tooling and labor, and are expensive with long lead times. Thrust chambers were designed for manufacture using conventional machining. As a result, designs required multiple pieces to ensure machine tool access to...

Typically, the cost of a spaceborne imaging system is driven by the size and mass of the primary aperture. Innovative solutions for imagers that are less complex and are lightweight are very desirable. Currently, telescopes such as JWST and ATLAST are very expensive and very complex.

The objective of the LTAS Simulator application is to transmit one or more streams of simulated LTAS data frames in User Datagram Protocol (UDP) packets to the network. Each LTAS data frame is filled with simulated data values, with each data field determined using several methods: 1) constant...

The Inductive Monitoring System (IMS) software uses data mining techniques to automatically characterize nominal system operation by analyzing archived system data. These nominal characterizations are then used to perform near-realtime...

Superconductivity, where electrical currents travel unhindered through a material, has many practical uses. It is used in applications extending from MRIs in hospitals to the cavities of particle accelerators. However, practical exploitation of superconductivity also presents many challenges.
