Description
This program targets the development of new highly anisotropic nonlinear optical nanocomposite materials for NASA and non-NASA applications in advanced photonic and optoelectronic devices and optical integrated circuits. Integration of electronic and optical components onto a single platform is becoming essential to advancing sensor, computational, memory, and communications technologies. Designing optical and electronic materials from the molecular scale up is expected to result in a new era of complex materials exhibiting enhanced optical properties, low processing costs, and substrate compatibility to enable device-on- a-chip technologies. The nonlinear optical materials for development in this program will be composed of complex nanocomposite heterostructures produced by molecular self-assembly derived from a well-characterized family of quasi one-dimensional electronic materials with chemically tunable optical properties and dynamics. These materials can be grown as single crystals or oriented thin films at low temperatures without epitaxial growth making their production low cost and platform-independent. These materials have intimately coupled optical and electronic activity and are transparent over much of the electromagnetic spectrum making them well suited for optoelectronic devices. The highly anisotropic and low-dimensional nature of these materials also provides highly oriented optoelectronic responses and quantum confinement effects that are desirable in advanced micro-optoelectronic devices.

Description
The Oregon Department of Geology & Mineral Industries (DOGAMI) contracted with Watershed Sciences, Inc. to collect high resolution topographic LiDAR data for multiple areas within the State of Oregon. The areas for LiDAR collection have been designed as part of a collaborative effort of state, federal, and local agencies in order to meet a wide range of project goals. This LiDAR data set was collected in 7 delivery areas from January 3 through July 14, 2010 and encompasses portions of the following counties in Oregon: Lincoln, Polk, Tillamook and Yamhill. This data set consists of bare earth and unclassified points. The average point density is 9.17 points per square meter over terrestrial surfaces. In some areas of heavy vegetation or forest cover, there may be relatively few ground points in the LiDAR data. Elevation values for open water surfaces are not valid elevation values because few LiDAR points are returned from water surfaces. LiDAR intensity values were also collected. This LiDAR data set was collected on different dates and organized into 7 deliveries. To determine which delivery or deliveries are in your area of interest, download yambo_deliveries.pdf at: ftp://coast.noaa.gov/pub/DigitalCoast/lidar1_z/geoid12a/data/1077/supplemental/yambo_deliveries.pdf The specific date of collection and total area covered for each delivery are listed below. Delivery 1: Date of Collection: 20100414 Total Area = 10,760 sq acres Delivery 2: Date of Collection: 20100301-20100605 Total Area = 62,451 sq acres Delivery 3: Date of Collection: 20100507-20100714 Total Area = 122,938 sq acres Delivery 4: Date of Collection: 20100103-20100527 Total Area = 97,317 sq acres Delivery 5: Date of Collection: 20100103-20100527 Total Area = 147,839 sq acres Delivery 6: Date of Collection: 20100305-20100515 Total Area = 84,277 sq acres Delivery 7: Date of Collection: 20100317-20100714 Total Area = 167,271 sq acres

Description
The innovation proposed here is a computational framework for high performance, high fidelity computational fluid dynamics (CFD) to enable accurate, fast and robust simulation of unsteady turbulent, reacting or non-reacting flows involving real or ideal fluids in several applications. This framework will provide a state-of-the-art unsteady turbulent flow simulation capability employing Hybrid RANS-LES (HRLES) methods which are a blend of Reynolds Averaged Navier-Stokes (RANS) and Large Eddy Simulation (LES) approaches. Low-dissipation schemes will be employed which will enable high-fidelity modeling of unsteady flows as well as acoustic fields. Additionally, Lagrangian particle tracking and Eulerian multiphase models will be incorporated to enable simulation of multiphase combustion involving solid particles or liquid droplets. The work proposed here will result in a state-of-the-art design and analysis tool to enable the accurate modeling of: (a) multiphase combustion in solid and liquid rocket engines, (b) combustion stability analysis (c) acoustic fields of space propulsion syatems in near-ground operation, (d) small valves and turbopumps, etc. which constitute critical components of versatile space propulsion engines part of NASA's Constellation Program.

MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.

Description
The Coastal Zone Color Scanner Experiment (CZCS) was the first instrument devoted to the measurement of ocean color and flown on a spacecraft. Although other instruments flown on other spacecraft had sensed ocean color, their spectral bands, spatial resolution and dynamic range were optimized for land or meteorological use and had limited sensitivity in this area, whereas in CZCS, every parameter was optimized for use over water to the exclusion of any other type of sensing. CZCS had six spectral bands, four of which were used primarily for ocean color. These were of a 20 nanometer bandwidth centered at 443, 520, 550, and 670 nm. Band 5 had a 100 nm bandwidth centered at 750 nm and a dynamic range more suited to land. Band 6 operated in the 10.5 to 12.5 micrometer region and sensed emitted thermal radiance for derivation of equivalent black body temperature. (This thermal band failed within the first year of the mission, and so was not used in the global processing effort.) Bands 1-4 were preset to view water only and saturated when the IFOV was over most types of land surfaces, or clouds.

Description
Access to space for Small Satellites is enabled by the use of excess launch capacity. An integration process that minimizes risk to the primary, allows parallel integration and predictable cost/schedule for the secondary enables use of that capacity. Design_Net has developed and flown a Falcon 1 RideShare Adapter (RSA) and is developing a RSA for the Minotaur IV, EELVs and Falcon 9. An RSA is more than structure, it must have electronics to provide a single simple interface to the launch vehicle (constant from mission to mission), yet provide a standard set of services to Payloads. DNet has leveraged work on the Falcon RSA, work on advanced AFRL Plug and Play avionics and commercial investments to develop a modular Secondary Payload Support Unit (SPSU). SPSU provides deployment, power distribution, and telemetry services for secondaries. We propose building on that work by adding video capability to verify and evaluate payload deployment. During Phase 1 we develop the video to PDR level (Begin TRL 3; End TRL 4) and during Phase 2 carry development of that module coupled with the rest of the SPSU (currently at TRL 6) to TRL 8 and have a system ready for flight in 2012 timeframe.

To support NOAA Coral Reef Conservation Program (CRCP) long-term goals for sustainable management and conservation of coral reef ecosystems, towed-diver surveys (AKA towboard surveys) are conducted by the Coral Reef Ecosystem Division (CRED) of the NOAA Pacific Islands Fisheries Science Center (PIFSC) as part of Pacific Reef Assessment and Monitoring Program (RAMP) Cruises. 2 towboard surveys (totaling 4.58 km in length) were conducted at Sarigan in Mariana Archipelago from 20140325 to 20140518 as part of RAMP Cruise HA1401. Towboard surveys are a good method for obtaining a general description of large reef areas, assessing the status of low-density populations of large-bodied reef fish, large-scale disturbances (e.g., bleaching), general distribution and abundance patterns of macro-invertebrates (e.g., crown of thorns sea stars, giant clams), and for assessing trends in these populations and metrics. A pair of scuba divers (1 fish diver and 1 benthic diver) are towed 60 m behind a small survey launch at a speed of 1-2 knots and a depth of approximately 15 m. Each survey is 50 min long, covers about 2 km of habitat, and is divided into ten 5-minute survey segments. The fish diver records, to the lowest possible taxon, all large-bodied reef fishes (greater than 50 cm total length) seen within 5 m either side and 10 m in front of the towboard. Length of each individual is estimated to the nearest cm. The fish towboard is also outfitted with a forward-facing digital video camera to record the survey swath. The benthic diver records percent cover of coral and macroalgae, estimates benthic habitat type and complexity, and censuses a suite of benthic macroinvertebrates including crown of thorns sea stars and sea urchins. The benthic towboard is equipped with a downward-facing digital still camera which images the benthos at 15-second intervals. These images are analyzed for percent cover of coral, algae, and other benthic components. Both towboards are equipped with SEABIRD SBE-39 temperature/depth sensors set to record at 5-second intervals. Latitude and longitude of each survey track is recorded at 15-second intervals using a Global Positioning System (GPS) receiver onboard the tow boat. A layback algorithm is applied to more accurately map the position of the divers with respect to the reef environment. This algorithm calculates the position of the divers based on the position of the tow boat taking into account the length of the tow rope, the depth of the divers, and the curvature of the survey track. This metadata applies to the fish biomass observations.

Intelligent Automation Inc. (IAI) proposes an innovative Security-Enhanced Autonomous Network Management (SEANM) scheme for reliable communication in space networking. The SEANM scheme allows the system to adaptively reconfigure its network elements based upon awareness of network conditions, policies, and mission requirements. Existing network management tools in space networking are generally focused on specific missions and/or domains and hence do not provide an integrated and consistent solution for the future NASA space networks. Moreover, to reduce operation costs, autonomous network management is necessary. However, the related research and implementations are still at early stage and demands further investigation. In addition, due to the inherent characteristics of space networks, security aspects that are valid in the traditional networks are not fully suitable to space networks. A novel network management solution with advanced scalability and security is necessary for heterogeneous space networks. The objective of the proposed SEANM scheme is to develop an autonomous network management system so as to provide reliable and efficient support for the science and exploration mission in the future NASA space networks.
