We propose to develop an innovative solar thermal system for oxygen production from lunar regolith. In this system solar radiation is collected by the concentrator array which transfers the concentrated solar radiation to the optical waveguide (OW) transmission line made of low loss optical fibers. The OW transmission line directs the solar radiation to the thermal receiver for processing of lunar regolith for oxygen production. Key features of the proposed system are: 1. Highly concentrated solar radiation (~ 4W103suns) can be transmitted via the flexible OW transmission line directly to the thermal receiver for oxygen production from lunar regolith; 2. Power scale-up of the system can be achieved by incremental increase of the number of concentrator units; 3. The system can be autonomous, stationary or mobile, and easily transported and deployed on the lunar surface; and 4. The system can be applied to a variety of oxygen production processes. The proposed Phase II program consists of the following tasks: Task-1: Develop an engineering prototype of the solar thermal system. Task-2: Integrate the solar thermal system with the carbothermal process reactor for utility demonstration and performance evaluation. Task-3: Improve the key components to the level acceptable for a space-based operational system.

Lake Mead is a large interstate reservoir located in the Mojave Desert of southeastern Nevada and northwestern Arizona. It was impounded in 1935 by the construction of Hoover Dam and is one of a series of multi-purpose reservoirs on the Colorado River. The lake extends 183 km from the mouth of the Grand Canyon to Black Canyon, the site of Hoover Dam, and provides water for residential, commercial, industrial, recreational, and other non-agricultural users in communities across the southwestern United States. Extensive research has been conducted on Lake Mead, but a majority of the studies have involved determining levels of anthropogenic contaminants such as synthetic organic compounds, heavy metals and dissolved ions, furans/dioxins, and nutrient loading in lake water, sediment, and biota (Preissler, et al., 1998; Bevans et al, 1996; Bevans et al., 1998; Covay and Leiker, 1998; LaBounty and Horn, 1997; Paulson, 1981). By contrast, little work has focused on the sediments in the lake and the processes of deposition (Gould, 1951). To address these questions, sidescan-sonar imagery and high-resolution seismic-reflection profiles were collected throughout Lake Mead by the USGS in cooperation with researchers from University of Nevada Las Vegas (UNLV). These data allow a detailed mapping of the surficial geology and the distribution and thickness of sediment that has accumulated in the lake since the completion of Hoover Dam. Results indicate that the accumulation of post-impoundment sediment is primarily restricted to former river and stream beds that are now submerged below the lake while the margins of the lake appear to be devoid of post-impoundment sediment. The sediment cover along the original Colorado River bed is continuous and is typically greater than 10 m thick through much of its length. Sediment thickness in some areas exceeds 35 m while the smaller tributary valleys typically are filled with less than 4 m of sediment. Away from the river beds that are now covered with post-impoundment sediment, pre-impoundment alluvial deposits and rock outcrops are still exposed on the lake floor. For more information on the seismic surveys see http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=1999-014-FA These data are also available via GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean ( http://www.virtualocean.org/) earth science exploration and visualization applications.

Description
A Mars ascent vehicle (MAV) uses solid rocket motors to propel soil samples into orbit, but the motors cannot provide steering. Cold gas thrusters are used for initial steering and spin stabilization for the final stage of flight. This approach is heavy and results in a spinning sample container in orbit, which is difficult to recover. Wickman Spacecraft & Propulsion Company (WSPC) proposes innovative hot gas thrusters for steering that use the gases from the solid rocket combustion chambers. This approach reduces weight and provides a non-spinning orbiting container to increase mission success probability. WSPC is the only company with hot, metalized gas valve technology. The MAV valves must handle metalized gases at 5,600 F. Minuteman motor experience and WSPC tests indicate that thin layers of tungsten in discrete valve locations would work for this application. WSPC will create a layout of a MAV hot gas TVC system to ensure the weight is less than the baseline cold gas system. Valve materials will be tested with the MAV propellant to ensure the valve operates properly. Phase II will be the testing of the TVC system with the first stage MAV solid rocket motor to simulate a MAV ascent into orbit.

To-date, the realization of small-scale, high-performance liquid bipropellant rocket engines has largely been limited by the inability to operate at high chamber pressures in a regeneratively-cooled environment using on-board pumps for propellant pressurization. Ventions seeks to fulfill this critical need by using a novel fabrication scheme to realize small-scale thrust chambers and turbopumps, and proposes to extend its previously-demonstrated technologies (under DARPA and NASA sponsored efforts) to develop a 3,000lbf, regeneratively-cooled, cryogenic propulsion system with a T/W ratio of approx. 100 and a vacuum Isp up to 355sec.

Description
Micron-thin surface hot-film signatures will be used to simultaneously obtain airspeed and flow direction. The flow-angle and airspeed sensor system (FASS) will provide airspeed with practically zero-lag and to less than one knot accuracy and flow angularity to a fraction of a degree, with natural immunity to EMI and RFI. Unlike Pitot-static and other conventional techniques, which experience serious limitations in accuracy, pneumatic lags, and frequency response in thin upper atmospheres, FASS will measure airspeed all the way to zero knots and perform equally well at sea level as well at high altitudes and even in the thin Martian atmosphere. The FASS addresses important flight-operation and flight research problems with crucial impact on vehicle performance, stability & control, structural loads, and pilot action. FASS will permit easy integration with aircraft avionics systems including conventional instruments used for pressure, temperature, and density measurements. Sensor elements will be coated to withstand harsh environment and waterproofed for underwater applications. FASS will be developed and marketed both as a stand-alone device and as an embedded, non-intrusive system. Commercial applications include aerospace vehicles, submarines, ships, boats, atmospheric wind sensing, oceanographic measurements, and tall structures.

To advance the state-of-the-art uplink laser communication technology, new adaptive optic beam compensation techniques are needed for removing various time-varying atmospheric disturbances on an uplink laser beam. The net effect of atmospheric wavefront turbulence produces degraded laser beam quality and limited data transfer rates and communication range. Crystal Research, Inc. proposes to develop a new type miniaturized adaptive optic device that is capable of removing all significant atmospheric turbulence distortions. The proposed device is based on electro-optic phase modulation in a single crystal substrate through electro-optic effect. By avoiding actuator systems associated with moving mirrors, the proposed innovation not only significantly reduces cost, size, weight, and power consumption, but also greatly enhances the system performance and reliability. The superior parameters of the proposed device could enable meeting the stated NASA mission goals of boosting data transfer rates in optical communication by a factor of 10-100 relative to the current state of the art. The new capabilities of the proposed adaptive optic device could lead to important advances in deep space and other optical communication systems. In Phase I, we will fully exploit the advantages and feasibility of the proposed concept by demonstrating critical component technologies in laboratory breadboard experiments.

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.

A RESON SeaBat⢠7125 multibeam echosounder in conjunction with an Applanix Position Orientation Solution for Marine Vessels (POS MVâ¢) WaveMaster system motion sensor, HYPACK®/HYSWEEP® navigation software, and Ashtech Z-Xtreme GPS receivers or Trimble R8 receivers was used to survey the Missouri River bed at 15 pipeline crossings at four different locations, at three power plant locations, and at one transmission tower during the 2011 flood event. The format of this data is a grid with each cell covering 0.5 meter by 0.5 meter. The elevation value (North American Vertical Datum, NAVD88) represented by each cell is the most probable elevation for that cell based on calculated Total Propagated Uncertainty (TPU) as calculated in Caris HIPS and SIPS software. Calculated TPS values are then used by Caris to create a Combined Uncertainty and Bathymetric Estimator (CUBE) surface. The surface grid was used to export the cell centroid position (Northing, Easting in UTM zone 14 North, in meters) along with the cell elevation (referenced to NAVD88, in meters) to create the text file. The data were collected by the U.S. Geological Survey in cooperation with the Environmental Protection Agency (EPA) and the Omaha Public Power District (OPPD).
Dual Use Catalytically Initiated Combustor (CIC) for Rocket Engine Ignition and Thruster Applications Project

Summary
Description
This proposal responds to subtopic O2.02 "Propulsion Technologies" and the stated need to develop component technologies that will lead to future propulsion systems that are reliable and have adequate performance without requiring excessive specialized handling equipment and procedures or needing to push materials and designs to the limits of their capabilities. We propose the development of a low part count and low energy Catalytically Initiated Combustor (CIC) that can serve as a rocket engine igniter as well as the basis for a family of low cost and highly reliable launch vehicle and satellite thrusters. We propose a 6-month Phase I program to 1) demonstrate reliable ignition and operation of our baseline CIC with hydrogen, methane, and propane fuels, 2) demonstrate reliable ignition and operation of our baseline CIC under cold gas inlet conditions, 3) demonstrate extended duration hot fire testing and durability of our CIC design over multiple ignition cycles, and 4) demonstrate rapid pulsed operation necessary for a launch vehicle or space craft thruster application. Under our proposed Phase I effort, we will also conduct a market survey of potential customers and define a flight weight CIC with maximum commercial utility as either an igniter or small thruster.

The deleterious effects of lunar dust, typically less than 50 5m in diameter, have to be addressed prior to establishing a human base and long duration human presence on the surface of the moon. These effects include abrasion of seals, gaskets, motors, actuators, gimbals, bearings, blocking of optical windows, and coating of thermal control surfaces and solar panels with lunar dust. Negative physiological effects due to dust inhalation by astronauts must be mitigated. Issues related to lunar dust have been identified since the Apollo missions; however, no credible mitigation techniques have been implemented to date. The essence of this proposed activity is to develop a multi-use coating system - a highly wear resistant coating surface for use in the space environment that can also perform as part of an electrically conductive circuit upon demand to minimize wear surface abrasion and, when electrically activated, repel fine lunar dust particles from wear surfaces, sealing surfaces, and complex geometries.

The Fish and Wildlife Service Service has identified the bottomland hardwoods of the Lower Mississippi River Delta as one of the highest Service priorities for waterfowl habitat within the United States. The Cache River National Wildlife Refuge CRR has been recognized as a high value basin in the Mississippi Delta for wintering migratory waterfowl. The Cache River Basin is subject to agricultural runoff from upstream and surrounding farmlands. Even though the use of organochlorine OC pesticides has drastically declined, these compounds have a slow rate of decomposition. It is therefore essential to analyze fish samples to determine if agricultural runoff is impacting the resources on the Cache River Refuge. Each fish sampling site. exceeded the 85 percentile for copper and mercury. All concentrations of chromium from the sampling sites were below EPA recommended levels for fish tissue concentrations. Additional studies should be conducted to determine possible sources of the inorganic and organic contaminants found on and near the CRR in order to control their release and controlreduce possible contamination of the Services trust resources, particularly fish eating migratory birds.
