<p>System on a chip is a method to increase engineering efficiency. State of the art components are increasing in gate count as expected according to Moore&rsquo;s law. In the past, a single engineer could write all of the code that would be placed into a smaller programmable component. As component density has increased, it now typically takes several engineers to develop a single chip. In the near future, design modularity and design reuse will be required to maintain engineering efficiency.</p><p>System on a chip allows NASA to develop or buy a library of functions which can be stitched together using a common interconnect bus. This promotes code reuse and greatly increases the speed at which a large, complex design can be developed. The direct benefits are efficiency and remaining competitive. This design methodology paves the way for the final goal of developing a complete spacecraft on a chip.</p><p>The goal of this project is to lay the key groundwork for being able to build a complete spacecraft on a chip.</p>

NASA requires protocols and architectures that will allow reduced levels of mission funding, shorter mission development schedules, and facilitate high availability of flight electronic components. The administration is strategically moving towards Internet based architectures and technologies. Internet protocols, however, are not designed for space communications and must be seamlessly adapted to support the characteristics of this environment. We are proposing the development of a Universal Space IP Transparent Proxy that leverages an innovative modular architecture to achieve accurate network monitoring and measurement as a means to effectively deal with design and performance problems of IP protocols in space environments.

Encouraged by Phase I accomplishments, the proposed Phase II program will significantly mature and align the development of a Space Qualified Non-Destructive Evaluation & Health Monitoring system with the needs of NASA. We are systematically working to improve the TRL to 5 at the end of Phase II and formulate commercialization and product development strategy beyond Phase II. The proposed health monitoring system features three innovative technologies: excitation of preferential Lamb/Rayleigh wave modes; utilization of phased array concepts; and utilization of software algorithms rather than hardware for beam forming and signal analysis. The ability to detect cracks, corrosion, disbonds, and cracks under bolts for a stiffened panel was demonstrated in Phase I. The detection methods used were pitch-catch, pulse-echo, phased array, and electromechanical impedance. To efficiently and cost-effectively achieve Phase II objectives, NextGen has teamed with Lockheed Martin Space Systems - Michoud Operations to test the proposed system in realistic environment. A cryogenic, composite LOX tank, built by Lockheed Martin for the X-34, is currently in a test fixture at NASA Marshall and will be used for evaluating our system. Additional tests will be performed to validate the durability and survivability of the system for space certification.

This data set provides soil maps for the United States (US) (including Alaska), Canada, Mexico, and a part of Guatemala. The map information content includes maximum soil depth and eight soil attributes including sand, silt, and clay content, gravel content, organic carbon content, pH, cation exchange capacity, and bulk density for the topsoil layer (0-30 cm) and the subsoil layer (30-100 cm). The spatial resolution is 0.25 degree. The Unified North American Soil Map (UNASM) combined information from the state-of-the-art US General Soil Map (STATSGO2) and Soil Landscape of Canada (SLCs) databases. The area not covered by these data sets was filled by using the Harmonized World Soil Database version 1.21 (HWSD1.21). The Northern Circumpolar Soil Carbon (NCSCD) database was used to provide more accurate and up-to-date soil organic carbon information for the high-latitude permafrost region and was combined with soil organic carbon content derived from the UNASM (Liu et al., 2013). The UNASM data were utilized in the North American Carbon Program (NACP) Multi-Scale Synthesis and Terrestrial Model Intercomparison Project (MsTMIP) as model input driver data (Huntzinger et al., 2013). The driver data were used by 22 terrestrial biosphere models to run baseline and sensitivity simulations. The compilation of these data was facilitated by the NACP Modeling and Synthesis Thematic Data Center (MAST-DC). MAST-DC was a component of the NACP (www.nacarbon.org) designed to support NACP by providing data products and data management services needed for modeling and synthesis activities.

Summary
Description
The Cape Romanzof Long Range Radar Site Cape Romanzof contains many petroleumrelated spills and hazardous substances. Therefore, in 1987 and 1988 a field study was conducted by the U.S. Fish and Wildlife Service Service to determine if contaminants from station activities had entered the Yukon Delta National Wildlife Refuges Refuge environment andor trust resources. Analytical results indicate that elevated levels of some polycyclic aromatic hydrocarbons PAHs, organochlorines and trace elements most likely originating from Cape Romanzof are accumulating in wildlife tissue. Most notable were organochlorine compounds in vole, fox and fish samples. Detected were: 1 p,p DDE in all but one sample 0.06 .15 ppm and p,p DDD in vole and fish samples 0.01 0.06 ppm, and 2 total PCBs in all samples voles, 0.95 1.14 ppm; fox adipose fat, 0.58 ppm; fish muscle, 0.16 1.22 ppm. Pathways of uptake include contact, ingestion, or inhalation of contaminated soil, sediment, water, waste or food e.g. fish, small mammals, birds. Sediment samples collected by the Service and water and sediment samples collected by WoodwardClyde Consultants indicate that the Old Landfill is a primary contributor of PAHs, PCBs, chlordane, lead and cadmium contamination.

High-efficiency UV detectors will be developed in the Phase II program with ZnO and its alloy (ZnBeO). ZnO and ZnBeO are a very suitable material for fabrication of high-speed, high-detectivity, and radiation-hard UV detectors due to their unique structural, electrical and optical properties. The proposing company (MOXtronics) has shown the feasibility of fabricating new ZnO p-i-n UV detectors in the Phase I. Such UV photodiodes will be improved for high-efficiency UV detection by using heterojunction p-i-n structures and/or Schottky contacts. In the Phase II efforts, commercial-typed heteojunction ZnO/ZnBeO-based PIN and MSM photodiodes will be fabricated and demonstrated. These photodiodes will be used for broad near-to-far UV detection.

Summary
Description
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Bathymetry, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities off southern New England, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During July-August 2008 NOAA completed hydrographic survey H11922 west of Gay Head, Massachusetts, in Rhode Island Sound and during July and September 2010 bottom photographs and surficial sediment data were acquired as part of ground-truth reconnaissance surveys of this area. Interpretations were derived from the multibeam echo-sounder data and the ground-truth data used to verify them. For more information on the ground-truth surveys see http://quashnet.er.usgs.gov/data/2010/10033/ and http://quashnet.er.usgs.gov/data/2010/10005/

The VASIMR propulsion system uses a high temperature Loop Heat Pipe (LHP) radiator to reject heat from the helicon section. The current baseline radiator uses titanium/water LHPs, however, deployable radiator and trace heating features are required to keep the water in the condenser from freezing when the radiator is turned off. The proposed project will develop high temperature toluene LHP radiators that will minimize the freezing problem, since the freezing temperature of toluene is roughly 100<SUP>o</SUP>C lower than water. Preliminary calculations on the toluene LHP radiator showed that a graded wick is required, with the pore size decreasing from the center to the surface of the wick. One goal of the project is to develop a graded alumina wick that reduces wick mass, back conduction, and pressure drop, enabling toluene as the working fluid. The ceramic wicks will also have near net shape fabrication, eliminating much of the current machining which adds costs to the LHP wicks. Optimizing the radial variation in porosity and permeability reduces the transport line sizes of toluene LHPs, significantly improving their mass and performance. The ceramic wicks can also be used in conventional LHPs, potentially reducing the LHP wick mass, pressure drop, and back conduction by 50 to 90% when compared with conventional nickel wicks. Phase I will demonstrate the feasibility of fabricating these wicks, demonstrate the wicks' machine-ability, conduct life tests, and evaluate the benefits of a graded wick versus a conventional wick with uniform properties. In Phase II, ACT will fabricate and test toluene LHP radiators with graded ceramic wicks to fully demonstrate their performances. We expect the technology to reach TRL 6 at the end of Phase II.
