Description

<p>We propose to develop a new landing approach that significantly reduces development time and obviates the most complicated, most expensive and highest-risk phase of any landing mission. The concept is a blanket- or carpet-like two-dimensional (2D) lander with a low mass/drag ratio, which allows the lander to efficiently shed its approach velocity and provide a more robust structure for landing integrity. The flat nature and low mass of these landers allows dozens to be stacked for transport and distributed <em>en masse</em> to the surface. The concept leverages recent developments in microelectronics and MEMS technology, such as the lab-on-a-chip, integrated RF comm, and laser probes.</p>

Description

All electronic systems are prone to wear-out and eventual failure and this has direct implications for Vehicle Health Management for NASA with its long space missions. The accurate prediction of an impending failure can provide significant savings in functionality and mission success.[1] Accurate and timely failure prediction can support the mitigation of catastrophic faults in spacecraft systems as well as autonomous control and dynamic repairs to faults. Electronic prognostics provide advanced warnings of impending electronic module failures. The specific innovation proposed will provide tools for setting and determining the advanced warning time for prognostic-enabled electronic systems, also referred to as defining the remaining useful life (RUL). The testbed will be a high efficiency, DC-to-DC Power Converter commonly found in advanced power systems. Such power converters are commonly found in a wide range of electronic systems to adjust power levels, yet are subject to failures. The innovation would help prevent data loss and support uninterrupted operation. The reason for funding is that NASA has a stated requirement for autonomous and automated solutions to systems health management systems and electronic prognostics are required to support this objective.

Description

We propose an alternative to using Microsoft Word for representing medical procedures that will make the procedures easier to construct and maintain, particularly when there are changes to the hardware or changes to the resulting format of the procedure. We call this alternative an "electronic procedure". Rather than a text-based document, this content-based document separates the text from the formatting standards and tags items contained in the procedure so that they can be recognized by other electronic systems. If a standard format changes, a reference to that format is updated. The electronic procedures can be re-converted in a single batch process, and the entire body of procedures will have the new format. Changes to hardware can be made in a similar manner, where changing a piece of hardware in a procedure will change all references to it in that procedure. Switching to this new representation offers many short and long-term benefits, which we describe herein. We have already demonstrated the use of electronic procedures for modeling ISS operational procedures (and in modeling one ISS medical procedure). We hope to extend this work into the medical operations field so we can demonstrate how medical procedures can benefit from this technology.

Description

This proposal addresses the need for miniature deep UV light sources that operate at very low ambient temperatures without heating or temperature regulation for use in advanced in situ planetary science instruments involved in the reagent-less detection and identification of trace amounts of organic, inorganic, and biogenic materials. The proposed sources are aluminum gallium nitride (AlGaN) semiconductor lasers and light emitting devices emitting between 210 nm to 250 nm, a spectral range which has been demonstrated to provide higher detection sensitivity and chemical differentiability than sources emitting at longer wavelengths. Instrument applications include non-contact, robot-arm or body mounted, reagentless chemical imaging instruments and detectors for analysis of chemical extractions from soil, rock, or ice employing non-contact, non-destructive native fluorescence and/or resonance Raman spectroscopic methods. The proposed semiconductor source approach avoids the problems that continue to limit emission wavelengths of semiconductor lasers to wavelengths above 340 nm. Using free electron injection we have demonstrated internal quantum efficiencies over 100 times higher than reported elsewhere. It is the goal of this program to demonstrate deep UV laser emission from a semiconductor device less than 250 nm using the proposed approach. This will lead to miniature, high efficiency, TRL 4 devices.

Description

Physical Sciences Inc (PSI) proposes the development of a longwave infrared (LWIR) imaging spatial heterodyne spectrometer (I-SHS) for standoff detection of clear air turbulence (CAT) and wake vortices from an airborne platform. PSI will team with Georgia Tech Research Institute (GTRI) who has produced significant research on the application of LWIR hyperspectral imaging for detection of these and other air hazards. The research has produced extensive simulations, however, the predicted spectral radiance signatures are an order of magnitude below the noise floor of state of the art in LWIR hyperspectral imagers. The proposed LWIR I-SHS will offer this order of magnitude improvement in noise equivalent spectral radiance through a combination of high throughput and minimal noise-inducing sampling errors owing to the stationary interferometer. A preliminary systems analysis predicts a per-pixel NESR of 1E-9 W/(cm^2 ster cm^-1) at 16 cm^-1 spectral resolution. In Phase I, PSI will formalize a system performance model and will produce and characterize a breadboard I-SHS which will be used to demonstrate a molecular imaging measurement as a surrogate for a wake vortex. With the support of GTRI, PSI will generate requirements and a conceptual design for a TRL 5 system to be developed in Phase II.

Description

The Gimbal-stabilized Compact Hyperspectral Imaging System (GCHIS) fully integrates multi-sensor spectral imaging, stereovision, GPS and inertial measurement, gimbal-stabilization, and gimbal-pointing-and-tracking capabilities into a compact light weight package. Advanced adaptive Kalman filter and attitude calibration algorithms are embedded for precision inertial measurement and real-time platform stabilization/pointing control. Innovative multi-thread-coded, fully parallel execution software is implemented with the latest multi-core CPU, which makes operation of GCHIS seamless. GCHIS concurrently acquires pushbroom hyperspectral imagery and multispectral snapshot stereo pairs. It features: 1) at least a 1392 pixel swathwidth and 5nm spectral resolution in the VNIR range for hyperspectral imaging; 2) at least 1600 x 1200 frame size for four band multispectral imaging; 3) 12 bit digitization depth for all imaging components; 4) less than 20lbs complete instrument mass; and 5) 1/100 degree platform stabilization/pointing accuracy. GCHIS has a fast data rate for high resolution and large area coverage. GCHIS can deliver one-foot resolution orthorectified hyperspectral imagery and inch level resolution multispectral stereo imagery. With gimbaled stabilization and programmable pointing, GCHIS is highly resistant to air turbulence and can handle diverse flight profiles, e.g. non-linear corridors and block areas, high and low altitudes, re-visiting or repeated measurement for change detection, and etc.

Description

This work proposes to capitalize on our Phase I success in a novel visible-near infrared Stokes polarization imaging technology based on high performance fast tunable phase retarder and novel algorithms for analyzing and diagnosing biological phantoms and cells. Phase I results have demonstrated the feasibility of this technique in in-vivo analyzing biological phantoms and cells. In this Phase II proposal, Boston Applied Technologies Incorporated, will team up with the Catholic University of America and Georgetown University to further develop this technique and apply it to biological cell analysis. Prototypes Stokes imaging system with real time video will be designed and developed. Computer-aided diagnosis software will be further developed for the imaging system with improved classification accuracy and speed. The Stokes polarization imaging system and its computer-aided diagnosis software will be tested on fresh tissue samples from laboratory animals. The tissues will include normal tissues from multiple organs as well as cancerous tissue from laboratory animals. The Stokes images will be compared to reflectance confocal microscopy images and standard light microscopy images to reveal the polarization fingerprints of biological tissues/cells.

Description

This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the agricultural conservation practice (CPIS05), Combination of Irrigation Sources (CIS) on agricultural land by county. A combination of irrigation sources means one or more sources of irrigation, such as wells, ponds, or streams are used on agricultural land. (U.S. Department of Agriculture, 1995) This data set was created with geographic information systems (GIS) and database management tools. The acres on which CIS's are applied were totaled at the county level in the tabular NRI database and then apportioned to a raster coverage of agricultural land within the county based on the Enhanced National Land Cover Dataset (NLCDe) 1-kilometer resolution land cover grids (Nakagaki, 2003). Federal land is not considered in this analysis because NRI does not record information on those lands.

Description

<p>Until the former NIAC was closed, we had investigated a nano-meter accuracy formation flight method based on photon thrusters and tethers, Photon Tether Formation Flight (PTFF), with the maximum baseline distance over 10 km for the next generation NASA space missions. Since photons have extremely small thrust per power, thrust amplification by recycling photons between two high reflectance mirrors located separately in two pairing satellites was proposed to overcome the limit.</p><p>Our original emphasis was on propellant-free nanometer accuracy tethered formation flying, however, during our study on photon thruster demonstration, we discovered that our photon thruster (Photonic Laser Thruster, PLT) has a much larger potential in NASA mission applications than precision tethered formation flying. The potential resulted from a surprising discovery on the extraordinary stability of PLT against dynamic motions of mirrors in our unique active optical cavity, which may enable in space propulsion for an extremely wide range of unprecedented NASA missions. For example, 10,000 times recycling of photons with 15 kilo-watt input laser power, which can be delivered by a 100 kW solar panel would produce up to 1 N of photon thrust, which is sufficient to enable these missions.</p><p>One of most crucial technologies to scaling up and implementing the PLT is Directed Energy technology that has developed and matured long range delivery of high power laser beams. The state-of-the-art DE technology is capable of delivering powers of multi-mega-watts over distances of hundreds of km, and matured precision pointing and focusing capability. Recently, an AFRL researcher for DE unintentionally demonstrated ~5 mN (more than 100 times scaling up of our previous NIAC demonstration of 35 μN) photon thrust in PLT with the use of a kW-class Thin Disk Laser, although the laser was not optimized for PLT. Currently, the DE community is developing much higher power lasers, and the adaptation of such lasers for PLT can facilitate Newton-class PLTs in the near future. Therefore, the time has arrived to develop and implement PLT for a wide range of unprecedented in-space NASA applications and this is the motivation for the present NIAC Phase II proposal.</p>

Description

Georeferenced image, acquired on August 27, 1965 over a portion of the Ouray National Wildlife Refuge. Image covers the northern portion of the refuge including Leota and Johnson Bottoms. This data set is a georeferenced version of an original black and white aerial photograph downloaded from Earth Explorer USGS; www.earthexplorer.usgs.gov. The original photo Frame 131 was georeferenced against the 2009 NAIP image within ArcMap 10.1. Six to eight points were used in the georeferencing process. This data set provides a look back in time following the closure of the Flaming Gorge Dam. It allows a look at landscape features including riparian vegetation extent, existing farmland, shrublands, etc. It also provides an important look at the location of the Green River channel to interpret river dynamics and movement. The image covers most of Leota Bottom and all of Johnson Bottom. This image provides a snapshot soon after construction began on the wetland impoundments within Leota Bottom. Pixel resolution of this image is 0.6 meters. This image should be used for resource level interpretation only.
