The innovation is a compact, UAV compatible, high-definition hyperspectral imaging system. The system concurrently-acquires a hyperspectral image using a compact grating imaging spectrometer and a much-higher spatial resolution color photographic image using a portable, measurement-grade, high-definition CCD camera (2,000 x 1,312 pixel). The spectral resolution of the hyperspectral image is better ...

A critically important region of the electromagnetic spectrum is the hard X-ray/soft gamma-ray band from 10 KeV to a few MeVs. In this band, a wealth of astrophysical processes occur in an even greater diversity of astrophysical objects and phenomena, both on a compact and diffuse scale. Surprisingly, for such a pivotal region of the spectrum, the high energy sky is still quite unexplored in that ...

A program for the development of an active pulsed flow noise control solution for turbomachinery noise caused by rotor wake interactions with stators is proposed. The system utilizes an array of pulsed jet flows near the leading edges of several stator blades to generate volume velocity sources to counter the fluctuating lift dipole sources caused by the wake-stator interaction. By placing the aco ...

The development of thin-film coatings with an actively tunable solar reflectance is proposed for momentum control on solar sails. As currently conceived, maneuvering and attitude control on solar sail spacecraft is achieved by mechanically adjusting the angle of one or more solar sails or panels with respect to the solar flux to create torque. The maneuvering and propulsion force is obtained from ...

Active Control eXperts (ACX), Inc. proposes a Phase I research and development effort for the development, conceptual design, and proof-of-concept experiment of a hybrid active/passive sound attenuation system for aircraft interiors. While the attenuation of structural vibration and structure-borne sound using passive means is the current state-of-the-art, and active structural acoustic control (A ...

Vibration reduction will be an important contributor to the success of future earth observing platforms. Unwanted motion in the micrometer to nanometer range must be prevented from interfering with components requiring precise alignment and pointing such as telescopes and interferometers. Active structural control employing smart materials is an ideal technology for accomplishing this goal, howeve ...

NASA seeks new and innovative technologies for materials, processes, and manufacturing that will provide safe, reliable, lightweight, and less expensive launch vehicle and spacecraft components. This project focuses on improving the strength of the lightest weight material known to man, i.e., aerogels. Improvements in strength would allow these materials to be used on launch vehicles and in spacec ...

Ambitious near Earth and interplanetary missions require long life, high efficiency, high Isp primary propulsion. To address this need, Busek proposes to develop a Hall thruster with increased performance, reduce mass, reduced complexity and lower cost over state-of-the-art ion propulsion systems. In Phase I, using an existing nominally 2 kW thruster we propose to evaluate several innovative metho ...
