Description

Fire suppression systems provide an essential safety function onboard spacecraft. The transition away from halon-based systems has presented an opportunity for efficient and cost-effective alternative approaches. ADA Technologies proposes to develop a fine-water-mist fire suppression system suitable for use in microgravity. The ADA design features a single pressure tank with a patented effervescent-gas spray nozzle to generate droplets of a size that is optimum for fire suppression. The proposed work will modify ADA's current fine-water-mist device to allow for operation in reduced and micro-gravity environments. Design modifications will focus on providing a uniform mixture of water and atomization gas to the effervescent nozzle. The resulting extinguisher will be compact, simple, and rugged, with pound-per-pound better suppression capability than carbon dioxide fire extinguishers. ADA is teaming with the Colorado School of Mines to employ their expertise in micro-gravity combustion and related fire suppression test facilities. In Phase II, the designs will be refined and upgraded to improve their manufacturability, reduce weight and volume, and lower unit costs. The project team is collaborating with an aviation safety hardware supplier to market the systems to the commercial aircraft industry and is exploring industrial applications.

Description

<p>A sustained human presence on the Moon, Mars, or other celestial bodies, will require numerous disciplines to create technologies, solve current known problems, and anticipate new ones. One problem identified during the Apollo missions is plume ejecta: the expulsion of dust, regolith, or other loose material from the force of launch or landing.  Rocket plume effects on Mars will be different from those on the Moon. Because Mars has an atmosphere, ejected particles will not travel as far, meaning that infrastructure could be placed at a safe distance from the launch pad and not receive blast effects. However, the presence of an atmosphere will cause the rocket exhaust to collimate, which will probably produce much deeper craters than the Apollo missions produced on the Moon. </p><p>Plume ejecta was observed and photographed during the recent landing of the Mars rover, Curiosity. Even though the sky crane landing system was designed to minimize plume effects on the Mars surface, areas of surface erosion were observed after landing. Curiosity is the largest vehicle that has landed on Mars. A human-sized lander will be considerably larger, will have more powerful rockets, and therefore, will probably disturb the surface soil much more. Deploying a landing pad or stabilizing the soil can mitigate this problem.</p><p>The goal of this project was to develop technology for building a landing pad through the following tasks:</p><ol><li>Demonstrate microwave sintering under Mars like conditions.</li><li>Investigate surface stabilization methods used for terrestrial applications and develop recommendations for a Mars landing pad based on these methods.</li><li>Develop a plan for implementing a microwave sintering system on a mobile rover.</li></ol><p>The project was completed successfully, achieving the first ever sintering of a Mars simulant under Mars like conditions.  In addition, a design for a rover mounted sintering system was created.  Recommendations for initial soil measurements were developed based of off terrestrial experience.</p>

Description

NOAA's National Geophysical Data Center (NGDC) is building high-resolution digital elevation models (DEMs) for select U.S. coastal regions. These integrated bathymetric-topographic DEMs are used to support tsunami forecasting and modeling efforts at the NOAA Center for Tsunami Research, Pacific Marine Environmental Laboratory (PMEL). The DEMs are part of the tsunami forecast system SIFT (Short-term Inundation Forecasting for Tsunamis) currently being developed by PMEL for the NOAA Tsunami Warning Centers, and are used in the MOST (Method of Splitting Tsunami) model developed by PMEL to simulate tsunami generation, propagation, and inundation. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources, including NGDC, the U.S. National Ocean Service (NOS), the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE), the Federal Emergency Management Agency (FEMA), and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to the vertical tidal datum of Mean High Water (MHW) and horizontal datum of World Geodetic System 1984 (WGS84). Grid spacings for the DEMs range from 1/3 arc-second (~10 meters) to 3 arc-seconds (~90 meters).

Description

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate. Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion. As a result, there is an increased demand for accurate information regarding past and present shoreline changes. To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project. There is no widely accepted standard for analyzing shoreline change. Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments. The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast. The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.

As a guide to newcomers and visitors, fishery biologists have compiled a list of some of the wellknown fishing waters in Alaska. The list is merely a starting point and makes no pretense at completeness. It will, however, serve to point out a number of the fishing spots, the important sport fish there and a guide to facilities available. With a little experience the new angler will seek out his own fishing spot, not to be found in this brief list. For convenience, fishing waters are tabulated for Southeastern Alaska, Anchorage Kenai Region, Kodiak, Alaska Peninsula and Northern Alaska.

Description

Liquidmetal Technologies (LMT) and the University of Southern California (USC)'s M.C. Gill Composites Center team up to develop manufacturing processes for large-scale bulk metallic glass (BMG) and fiber laminate systems for aerospace applications. The proposed innovation consists of the development of a process to manufacture thin BMG sheets (150mm x 300mm x 0.1-1mm) by tube casting and hot rolling along with a process to fabricate fiber metal laminates (FMLs) utilizing the BMG sheets thereof and carbon fiber prepregs. While Phase I would focus on development of a small-scale prototype, the completed Phase I work would also give insight into the feasibility of large-scale manufacturing processes, such as vertical continuous casting, flash processing, autoclave moulding, out-of-autoclave moulding, and press moulding, many of which would be explored in a potential Phase II effort. Thus, in Phase I the technology readiness level (TRL) of the proposed innovation would increase from 2 to 3, and in Phase II the TRL would increase from 3 to 5.

Description

This raster data set represents water-level change in the High Plains aquifer of the United States from 1980 to 1995, in feet. The High Plains aquifer underlies 112.6 million acres (176,000 square miles) in parts of eight States: Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. The aquifer's saturated thickness ranges from near zero to about 1,200 feet (Weeks and Gutentag, 1981). Water-level declines occurred in parts of the High Plains aquifer soon after the onset of substantial irrigation with groundwater (about 1950) (Luckey and others, 1981; Gutentag and others, 1984). This data set was generated in ESRI ArcInfo Workstation Version 9.3, which is a geographic information system (GIS), using water-level-change data from wells measured in 1980 and 1995 and from some additional wells in New Mexico, which were measured in 1996 and 1997. For this data set, areas of no substantial change were designated as areas where water-level change was between a rise of 3 feet and and decline of 3 feet; the raster was set to zero in the areas of no substantial change.

Description

SNAP is designed to reduce food insecurity – reduced food intake or disrupted eating patterns in a household due to lack of money or other resources – but data quantifying this effect is limited. The objectives of this study were to: Assess how food security and food expenditures vary with SNAP participation. Examine how relationships between SNAP and food security and between SNAP and food expenditures vary by household characteristics and circumstances. Estimating the effect of SNAP on food insecurity using household survey data is challenging because households that choose to participate in SNAP can differ in systematic ways from households that do not participate, making it hard to distinguish the impact of SNAP from these other factors. This study sought to control for the SNAP participation “selection bias” by comparing information collected from households within days of entering the program (new entrants) to information obtained after about 6 months of participation.

Description

An eye-safe, multispectral cross-track scan subsystem with a large receiver aperture and a narrow FOV is proposed for the NASA Cloud Physics Lidar (CPL) to increase the horizontal scan area coverage. The /-14 degree cross-track scan capability will cover /- 5 km from nadir at a 20 km altitude. The cross-track scanner uses a bidirectional scan pattern, which collects 10,000 data points per cross track scan at a 5 kHz transmitter rep rate. Solar background is reduced with narrow bandpass filters and a narrow transmitter linewidth with center wavelength control. The scanner accounts for the return pulse lag angle due to pulse time of flight. The existing CPL vertical resolution is maintained at 30 m. Photon counting SPAD detectors and PMT's are used with photon counting modules and multichannel scalers, which support eye-safe operation. The compact receiver telescope design is achieved with a configuration that uses a fixed primary mirror and a scanning secondary mirror, which directs the return signal through a Coude path to the the detector optics bench. The multispectral lidar uses polarization discrimination on two of the three receiver channels, and the optics design supports a 100 urad receiver Instantaneous Field Of View to minimize the solar background noise.

Description

The NASA Jupiter Europa Orbiter (JEO) conceptual payload contains a thermal instrument with six different spectral bands ranging from 85m to 100lm. The thermal instrument is based on multiple linear arrays of thermopile detectors that are intrinsically radiation hard; however, the thermopile CMOS readout needs to be hardened to tolerate the radiation sources of the JEO mission. Black Forest Engineering (BFE) is developing a thermopile readout to tolerate the JEO mission radiation sources. On Phase II, BFE will test new circuitry for radiation hardness, complete the design of a 1x128 thermopile readout integrated circuit (ROIC) and fabricate the ROIC using 180 nm CMOS technology. The Phase II ROIC also includes on-chip 16-bit analog-to-digital conversion and serial digital output for system noise immunity. The Phase II ROIC will be characterized to meet the JEO thermal instrument requirement.
