Description

This is a subset of AMSR-E rain rat eproduct along CloudSat field of view track. The goal of the subset is to select and return AMSR-E data that are within +-100 km across the CloudSat track. Thus resultant subset swath is 45 pixels cross-track. Apart from that, all efforts are made to preserve the original HDF-EOS formatting of the source full-sized data. The Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) instrument on the NASA EOS Aqua satellite provides global passive microwave measurements of terrestrial, oceanic, and atmospheric variables for the investigation of water and energy cycles. The original, full-sized, product is Level-2B swath product (AE_Rain), and it contains instantaneous measurements of rain rate and rain type (convective vs. stratiform), generated from Level-2A brightness temperatures (AE_L2A). The Goddard Space Flight Center (GSFC) Profiling algorithm determines rain rate and type over ocean areas, and a Modified GSFC Profiling algorithm over land. Data are stored in HDF-EOS format, and are available from 18 June 2002 to present via FTP.

Description

Proposed for development is a proof-of-concept prototype for the final stage of a multistage cryocooler. This final stage comprises a high frequency pulse tube cold head that cools from an intermediate temperature of 10?20 K down to below the critical temperature of helium (5.2 K) using an alternate approach compared to conventional technology. This approach offers unique advantages that have never before been explored and will allow us to achieve high thermodynamic efficiency with compact size, using ordinary helium as the working fluid. The first and second stages that will eventually pre-cool the third stage cold head can be either existing commercial Sunpower Stirling cryocoolers or pulse tube technology now under development. If the third stage cold head proves successful all the pieces will be in place for developing a compact, efficient and reliable cryocooler.

Description

The objective of the project is to develop an open architecture, computer aided analysis and control design toolbox for distributed parameter systems, in particular, this effort aims at creating computational tools for emerging applications in aerodynamic analysis and control of high performance aerial vehicles. For small-unmanned aerial vehicles a well-designed network of micro actuators can enable aggressive performance not possible using traditional control surfaces such as ailerons, elevators, rudder and flaps. Even for larger aircraft the emerging paradigm of control involves an array of actuators and distributed sensing and actuation. In addition to enhanced performance these control architectures can provide greater redundancy to confront actuator failures. In Phase I, various aspects of the model definition, control parameterization, model reduction, control design and simulation for verification were illustrated for a benchmark problem. In addition, a computational architecture leveraging commonly available tools to the scientists/engineers was defined. The proposed toolbox in conjunction with commonly used general purpose software will provide designers the ability to seamlessly test control design for aerodynamic applications by integrating and automating several key steps in design cycle. These tools will find commercial applications not only in the emerging unmanned aerial vehicle industry but other land, sea and air vehicles as well.

Description

The Lunar Organic Waste Reformer (LOWR) utilizes high temperature steam reformation to convert all plastic, paper, and human waste materials into useful gases. In the LOWR, solar thermal concentrators are used to heat steam directly to 600 C, after which the steam is mixed with a small amount of oxygen and injected into a reactor which is being fed with waste materials via a lock hopper. At the high temperatures, the oxygenated steam will react with all organic materials to produce a gas mixture largely composed of hydrogen, CO and carbon dioxide. After removing the remaining steam from the product stream via condensation, the gases are dusulfurized and then fed to a catalytic reactor where they can be combined with hydrogen to produce methane, methanol, or other fuels. Both the necessary hydrogen and oxygen for the process can be produced by electrolysis of part of the water content of the waste material, which is extracted from the wastes directly by the reformer itself. With effective recycling of the steam, no consumables are lost in the process. All products are liquids or gases, making the system highly reliable and subject to automation. In the proposed Phase 2 program, Pioneer Astronautics will build a full-scale end-to-end LOWR system capable of turning 10 kg of waste per day into methane and oxygen.

Description

We propose to design a working prototype Geospatial Decision Support Toolkit (GeoKit) that will enable scientists, agencies, and stakeholders to configure and deploy their own web based applications containing maps, forms, algorithms, and a rich set of functionality related to visualization, analysis, querying, and publication of geospatial data and information. GeoKit will focus on development of a suite of tools that will operate on data, to create rule-based applications for risk analysis, risk mitigation, operations management, and science research support. GeoKit will enhance the the use of data from NASA and other sources, provide a tool for non-software developers to create a website with custom functions and tools that operate on geospatial data, and provide a framework for development of new tools to support risk assessment, risk management, and operational analysis of spatially- explicit data from NASA platforms, climate reanalyses, and user-defined sources, as well as allow real-time publication of results in standard geobrowser compatible formats.

Description

Hydrographic and Impairment Statistics (HIS) is a National Park Service (NPS) Water Resources Division (WRD) project established to track certain goals created in response to the Government Performance and Results Act of 1993 (GPRA). One water resources management goal established by the Department of the Interior under GRPA requires NPS to track the percent of its managed surface waters that are meeting Clean Water Act (CWA) water quality standards. This goal requires an accurate inventory that spatially quantifies the surface water hydrography that each bureau manages and a procedure to determine and track which waterbodies are or are not meeting water quality standards as outlined by Section 303(d) of the CWA. This project helps meet this DOI GRPA goal by inventorying and monitoring in a geographic information system for the NPS: (1) CWA 303(d) quality impaired waters and causes; (2) hydrographic statistics based on the United States Geological Survey (USGS) National Hydrography Dataset (NHD); and (3) special designations recognizing waters of exceptional quality as defined in State water quality standards. Hydrographic and 303(d) impairment statistics were evaluated based on a combination of 1:24,000 (NHD) and finer scale data (frequently provided by state GIS layers). Information on State-designated uses and waters of exceptional quality are only available for a limited number of parks at this time.

Description

Communications security (COMSEC) is essential to satellite communications. Its role continues to grow as the available bandwidth expands to meet the ever increasing strategic and tactical data requirements of the 21st century. NASA's exploration of planetary surfaces will require a communication architecture that supports operational capabilities in which assets can communicate seamlessly and securely to coordinate exploration as well as communicate back to Earth. The flexibility and pervasiveness of the internet, including the transition to IPV6, is already being extended to military space assets ? e.g. the global grid. NASAs adoption of these same standards appears likely. The specific problem addressed by the Aeronix Phase I SBIR is to identify and develop modifications to our existing High Assurance Advanced Security Module (ASM) solution that satisfy the NASA networking requirements. The innovation of the proposed solution is the development of an unclassified IP based network encryptor that is compatible with commercially available ground based HAIPE equipment operating with Suite B algorithms and the ability to operate in the presence of failures caused by the harsh environment of space.

Description

NASA seeks Unmanned Aircraft Systems (UASs) for Earth science data collection for missions with variable durations, operating proximities, altitudes, and environmental conditions. Of particular interest is the Ice Bridge mission, which takes observations in support of Arctic and Antarctic research by identifying ice sheet motion, three-dimensional ice features, and other atmospheric and surface effects. These UAS aircraft may be equipped with a variety of sensors, with each aircraft potentially completing a unique set of objectives, only some of which take advantage of or require distributed sensing. Such a flexible system demands that vehicles be capable of seamless entry and exit of aircraft from any distributed sensing task. The approach proposed here satisfies these needs through a distributed sensing architecture that allows cluster sensor information to interface with and influence a multi-aircraft, high-precision, closed-loop path planning and control system. In addition, the UAS path planner is capable of managing dynamic flight regimes, including high winds and turbulence, while ensuring proper target tracking. This combination of features maximizes mission utility and path repeatability.

Description

Lynntech proposes a novel flow control methodology for airfoils undergoing dynamic stall. Dynamic stall refers to an aerodynamic phenomenon that is experienced by airfoils that undergo rapid changes in the flow angle of attack such as rotorcraft based airfoils, flapping wing technologies as well as fixed wing aircrafts undergoing sudden angle of attack changes. Dynamic stall is inherently an unsteady, non linear and complicated effect that can affect such flight parameters as lift, drag and airfoil stability. Lynntech, along with its STTR partner in Dr. Noel Clemens and Dr. Jayant Sirohi, at the University of Texas at Austin proposes to use novel pulsed plasma discharge based actuators for flow control on dynamically stalled airfoils. Lynntech has more than 20 years of experience with applied plasma physics and 10 years of experience with turbulent CFD modeling. Dr. Noel Clemens at the University of Texas Flow Imaging Research Laboratory in the Department of Aerospace Engineering, who has implemented and tested various types of plasma actuators for flow control. The proposed technology consists of pulsed plasma actuators which will induce high velocity airflow within the airfoil boundary layer, thus reattaching the flow. The proposed plasma actuator can achieve high Reynolds number (>5e6) flow control compared to contemporary dielectric barrier discharge plasma actuators without relying on corona discharge / hot plasma technology. Advantages of the system include low power consumption, ease of installation, increased flight stability, reduced drag and higher stall angles.

Description

Traditional approaches for active flow separation control using dielectric barrier discharge (DBD) plasma actuators are limited to relatively low-speed flows and atmospheric conditions. It results in low feasibility of the DBDs for aerospace applications, such as active flow control at turbine blades, fixed wings, rotary wings and hypersonic vehicles, which require a satisfactory performance of the DBD plasma actuators at wide range of conditions, including rarified flows and combustion mixtures. An optimization of the DBD plasma actuators should be achieved using efficient, comprehensive, physically-based DBD simulation tool for different operation conditions. We propose to develop a DBD plasma actuator simulation tool for a wide range of ambient gas pressures. The proposed tool will treat DBD plasma kinetically at low pressures. At high pressures (atmospheric conditions) plasma will be treated using hydrodynamic approach. The proposed tool will be validated by comparison with the experimental and numerical data on the DBD investigations.

Description

The Nevada Division of Wildlife operates the Gallagher Fish Hatchery in the Ruby Lake NWR in Ruby Valley, Nevada. The results of previous sampling of water, sediment and aquatic vegetation that was conducted in September 1993 Wiemeyer and Tuttle 1995, suggested that copper and zinc concentrations in vegetations andor sediment samples from a ditch downstream of the fish hatchery. Copper sulfate is occasionally used by fish hatchery personnel to control algal blooms, usually in August and September of each year Martha Collins, personnel communication. These applications may be conducted both at the north fishrearing facility, about 15 miles north of refuge headquarters, and at the main hatchery complex, approximately 1.1 miles south of refuge headquarters. Concentrations of several metals and trace elements also appeared to be somewhat elevated in water, sediment, and vegetation samples collected at the south end of the South Marsh, at least when compared to other locations on the refuge. The Refuge Manager of the Ruby Lake NWR requested that the Nevada Fish and Wildlife Office collect various samples downstream of hatchery operations to determine if the fish hatchery could possibly be a source of metals and if they could have an adverse effect on refuge resources. Information was also needed on concentrations of metals and trace elements in aquatic invertebrates from the refuge as food items for fish and wildlife on the refuge.

Description

Atmospheric pressure sensing in particular is of critical importance to any attemp of Mars landing. Pressure sensing has traditionally always drawn high interest from the military due to its applications to high-performance military airplanes and helicopters, missiles and ballons. Aerodynamics also find its applications in civilian aviation. After over 100 years of research and development, most powered aerodynamic experiments can be accurately simulated numerically on a computer today. However, aerodynamic experiments and measurements are still needed for the input parameters to the simulation, for the final verification of results and routine monitoring of performance. As a matter of fact, precision aerodynamic measurements gain ever higher importance today than before. There are 3 special challenges of measuring pressure on Mars: (1) the thin atmosphere requires high ensitrivity sensors; (2) the extreme temerature range; and (3) the survival of the landing impact. This proposal address them all. At home on the Earch, air pressure measurements reveal a lot of useful information about aircraft engine performance, about the air flow on aircraft wings, about the on-blade dynamic pressure of a helicopter, and about the optimal design and motion of a parachute among other things. The unique advantage of our solution lies in its high stability against temperature variations and mechanical disturbances, rendering the proposed system rugged and robust enough for Mars landing and exploration while keeping the cost at the level of commercial off the shelf fiber-optic communications systems. In Phase I of this program, we propose to demonstrate a bench-top system with several high-sensitivity etalon pressure sensors with high temperature and mechanical stability. In Phase II, we will develop the complete pressure sensor system using existing fiber optic components with monitoring and feedback control software.
