The development of multi-meter diameter radiofrequency (RF) antennas for NASA and DoD will have a significant impact of future space programs. Polymer membrane technologies are well suited for large area deployable space antennas by significantly reducing the mass and volume of the launch vehicle. Low CTE polymer piezoelectric membrane technology is now at a maturity level to enable the development of high performance large area electrically formal membrane reflectors. Advanced COATING technology is crucial to enabling technological developmental of high performance RF antennas. The production of a conductive and highly reflective thermal control COATING that matches the CTE of the polymer membrane is at the center of this development program. In addition, in Phase I, the piezoelectric polymeric membrane had a significant deformation at the application of the electrical potential - this manifested the need for stress balancing the coating. Specifically, the objective is to develop the thin-film stress-balanced COATING that will precisely match the CTE of the polymer to the coating material itself, resulting in a zero CTE membrane/coating composite structure. In addition, the coated membrane will exhibit the required RF performance, thermal characteristics, and environmental endurance, such as: atomic oxygen (AO) resistance; visible and ultra-violet (VUV) radiation rejection; and space temperature extremes. Surface Optics Corporation (SOC) has considerable experience in producing RF/Thermal coatings and precisely controlled intrinsic stress thin-films; both are necessary to the success of this program. NeXolve is the partnering organization with SOC, providing the polymer membranes that have the appropriate piezoelectric formulation, surface properties, and zero CTE.

Cloud computing has the potential to permit scientists to scale up to solve large science problems without having to invest in hardware and software infrastructure. Even though its use has become commonplace in the business realm, its use in HPC is still limited to a few applications. This project aims at developing, prototyping, validating, and commercializing the world's first cloud-enabled acceleration library of linear algebra solvers. Considering that linear algebra is the most common computational bottleneck in scientific software applications (more than 70% of HPC cycles), the resulting Specialized Linear Algebra Cloud technology will directly impact numerous applications, such as the design of aerospace and automotive vehicles, exploration for new oil & gas reserves, nuclear energy research, and the design of computer chips, among many others. The Phase I work will incorporate innovations for removing the bandwidth bottleneck in the outsource model of a Specialized Linear Algebra Cloud. We will also design a core platform able to support solver-as-a-service technology in HPC environments. The Phase I technology will be evaluated in three different scenarios: (A) Infrastructure Cloud outsourcing computations to Specialized Clouds, (B) Infrastructure Cloud making use of internal Specialized Clouds, and (C) End-users accelerating code through direct access to Specialized Clouds. Accelogic's novel numerical libraries are expected to provide next-generation speed/efficiency to existing cloud systems, with direct application to NASA programs, other government applications, and many valuable uses in academia and the private sector. The Phase I proof-of-concept work should advance the technology from TRL 2 to TRL 3, and we expect to reach TRL 5 during Phase II. A world-class combination of experts in algorithm design, computer networks, and numerical analysis pursue these development goals.

The ALTUS Cloud Electrification Study (ACES) was based at the Naval Air Facility Key West in Florida. ACES researchers in August 2002 conducted overflights of thunderstorms over the southwestern corner of Florida. For the first time in NASA research an uninhabited aerial vehicle (UAV) named ALTUS was used to collect cloud electrification data. Carrying field mills, optical sensors, electric field sensors and other instruments, it allowed scientists to collect cloud electrification data for the first time from above the storm from it's birth through dissipation. This experiment allowed scientists to achieve the dual goals of gathering weather data safely, and testing new aircraft technology. This dataset consists of data from the Electric Field Mills which yield information about the atmospheric electrical fields above the instruments.
Gulf of Mexico Hypoxia Watch Bottom Dissolved Oxygen Contours for June and July SEAMAP Cruise of 2001

Summary
Description
The NOAA Hypoxia Watch project provides near-real-time, web-based maps of dissolved oxygen near the sea floor over the Texas-Louisiana continental shelf during a period that extends from mid-June to mid-July. The NOAA National Marine Fisheries Service Mississippi Laboratories at Pascagoula and Stennis Space Center and the NOAA National Coastal Data Development Center (NCDDC) at Stennis Space Center began the Hypoxia Watch project in 2001. Scientists aboard the NOAA Research Vessel Oregon II measure seawater properties, such as water temperature, salinity, chlorophyll, and dissolved oxygen at each of approximately 240 locations as the Oregon II cruises the waters south of Pascagoula, MS and then makes its way from Brownsville, Texas, to the mouth of the Mississippi River. A scientist aboard the ship processes the measurements from electronic dissolved oxygen sensors, checks the measurements periodically with chemical analyses of the seawater, then sends the data by e-mail to NCDDC at Stennis Space Center approximately every three to four days. Physical Scientists at NCDDC transform the dissolved oxygen measurements into contour maps, which identify areas of low oxygen, or hypoxia. During the thirty-day cruise, as the data is received from the ship, NCDDC generates new maps and immediately publishes them on the web. The first map will usually cover an area off the Mississippi coast, successive maps will add areas of the continental shelf from Brownsville to Corpus Christi, and the final map will usually cover the entire Texas-Louisiana-Mississippi coast. Maps are published every three to four days from approximately June 22 to July 20.

Description
The USGS, in cooperation with NOAA, is producing detailed maps of the seafloor off southern New England. The current phase of this cooperative research program is directed toward analyzing how bathymetric relief relates to the distribution of sedimentary environments and benthic communities. As part of this program, digital terrain models (DTMs) from bathymetry collected as part of NOAA's hydrographic charting activities are converted into ESRI raster grids and imagery, verified with bottom sampling and photography, and used to produce interpretations of seabed geology and hydrodynamic processes. Although each of the 7 continuous-coverage, completed surveys individually provides important benthic environmental information, many applications require a geographically broader perspective. For example, the usefulness of individual surveys is limited for the planning and construction of cross-Sound infrastructure, such as cables and pipelines, or for the testing of regional circulation models. To address this need, we integrated the 7 contiguous multibeam bathymetric DTMs into one dataset that covers much of Block Island Sound. The new dataset is adjusted to mean lower low water, is provided in UTM Zone 19 NAD83 and geographic WGS84 projections, and is gridded to 4-m resolution. This resolution is adequate for seafloor-feature and process interpretation, but small enough to be queried and manipulated with standard GIS programs and to allow for future growth. Natural features visible in the grid include boulder lag deposits of submerged moraines, sand-wave fields, and scour depressions that reflect the strength of the oscillating tidal currents. Bedform asymmetry allows interpretations of net sediment transport. Together the merged data reveal a larger, more continuous perspective of bathymetric topography than previously available, providing a fundamental framework for research and resource management activities off this portion of the Rhode Island coast.

The Neuse River Estuary in North Carolina is a broad, V-shaped water body located on the southwestern end of Pamlico Sound. This estuary suffers from severe eutrophication for which several water quality models have recently been developed to aid in the management of nutrient loading to the estuary. In an effort to help constrain model estimates of the fraction of nutrients delivered by direct ground-water discharge, continuous resistivity profile (CRP) measurements were made during the spring of 2004 and 2005. CRP is used to measure electrical resistivity of sediments, a property that is sensitive to difference in salinity of submarine ground water. The 2004 and 2005 surveys used floating resistivity streamers of 100 m and 50 m respectively. The depth penetration of the streamers is approximately 20% of the streamer length which translates to approximately 20-25 m with the 100 m streamer and 12-14 m with the 50 m streamer. These data were processed using AGI's EarthImager 2D software. CRP data enables the mapping of the extent and depth of the fresher ground water within the estuary.

The goal of this study was to inventory butterflies and skippers on a number of wetland prairie sites in southeastern North Dakota, and pinpoint the location and abundance of the Dakota Skipper Hesperia dacotae, Powesheik Skipper Oarisma powesheik, Regal Fritillary Speyeria idalia, and other rare butterflies. The sites inventoried are under the control of the U.S. Fish and Wildlife Service in three counties: Ransom, Richland, and Sargent. Surveys in 1997 began on 29 June and concluded on 10 July. As in the 19931996 North Dakota surveys, survey technique entailed walking transects of sites and recording the presence of species by quarter section, and exact locations of rare species. As in the 1996 surveys, the most significant finding in this survey is that four of the eight habitatrestricted butterfly and skipper species identified as rare in North and South Dakota are present on the prairies south of Stacks Slough Waterfowl Production Area. This report will document the results of the survey, with sites grouped into 5 areas, and detail sightings of rare species.
Electronic Correlated Noise Calibration Standard for Interferometric and Polarimetric Microwave Radiometers Project
Published By National Aeronautics and Space Administration
Issued over 9 years ago
Summary
Description
A new type of calibration standard is proposed which produces a pair of microwave noise signals to aid in the characterization and calibration of correlating radiometers. The proposed Correlated Noise Calibration Standard (CNCS) is able to generate pairs of broad bandwidth stochastic noise signals with a wide variety of statistical properties. The CNCS can be used with synthetic aperture interferometers to generate specific visibility functions. It can be used with fully polarimetric radiometers to generate specific 3rd and 4th Stokes parameters of brightness temperature. It can also be used with spectrometers to generate specific power spectra and autocorrelations. It is possible to combine these features and, for example, generate the pair of signals that would be measured by a fully polarimetric, spectrally resolving, synthetic aperture radiometer at a particular pair of polarizations and antenna baselines for a specified scene over a specified frequency band. The proposed CNCS will cover all the frequencies used for radiometric observations in the 1 to 40 GHz range. In specific, the Phase II project will develop the system prototypes for L and X bands. While intended for ground based characterization of radiometer systems, the technological approach is amenable to on-orbit calibration.

Description
To date, the majority of the gearboxes used on the rovers have been based on very conventional materials, process and designs. This has primarily been a result of the fast paced schedules associated with rover development. With little time for recovery, these programs are extremely risk adverse and the idea of developing new technology on the program is absolutely impractical. As there is no rover planned for the 2007 there is a longer than normal dwell between rover programs. The hope is to capitalize on this time to advance the technology used on the common gearboxes employed on the rover. This will allow new technology to be introduced into the gearbox designs. The plan for reducing the gearbox mass relies on a three pronged approach. First, design innovations above and beyond AGMA standards will be evaluated for incorporation into the basic planetary gearbox design. Second, advanced materials and processes will be evaluated for use in gears and planet bearings. And lastly, the cost implications of the advanced technology will be compiled to insure the correct balance is maintained between weight reduction and cost expense.

Monitoring the health and wellness of mission pilots is a critically important function. Space flight has an adverse effect on the human immune response. During space flight the immune system weakens and some herpes viruses that are typically latent begin to appear in the saliva. Currently, saliva samples are taken in space and preserved for post flight assay. The presence of reactivated herpes virus in saliva samples is an indication of a weakening immune defense. RST Bioscience LLC proposes an innovative in flight assay to monitor the efficacy of the immune system in-situ. RST Bioscience has designed a test that is perfectly suited for space flight. The test will be small, light weight and easy to use. The sample used in this test will be saliva, which can be easily collected through non-invasive means. Results are delivered in minutes to hours. The test is sterile and disposable, used sample is contained and disposed of along with the disposable kit. There is no heavy equipment needed to process samples or read results. The kit is self-contained. Phase 1 will focus on assay development. In phase 2 we will build and test a prototype of the disposable delivery device.
