We are proposing to utilize quantum dots to develop a super high-efficiency multijunction III-V solar cell for space. In metamorphic triple junction space solar cells, pioneered by Essential Research, Inc., the InGaAs junction or bottom cell of the three-cell stack is the current limiting entity. In Phase I of this program, we demonstrated that InAs quantum dots can be formed by MOVPE, and then incorporated in an InGaAs cell to provide sub-gap absorption and thus improve its short-circuit current. For the Phase II work, we propose to optimize this quantum dot InGaAs cell, and develop a three-cell stack to achieve a space solar cell whose efficiency would dramatically exceed current SOA standards. A theoretical estimate predicts that a InGaAlP(1.95 eV)/InGaAsP(1.35 eV)/InGaAs(1.2 eV) triple junction cell incorporating quantum dots to improve the bottom cell current would have an efficiency exceeding 40%. Quantum dots will allow NASA not only to improve device efficiency by expanding the spectral response of individual cells, but to improve the temperature coefficients and radiation tolerance as well. This is extremely important as NASA attempts to increase array specific power with new concentrator designs and continues to expand the range of environments to be encountered in future missions.

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).

On August 17, 1996, the Japanese Space Agency (NASDA - National Space Development Agency) launched the Advanced Earth Observing Satellite (ADEOS). ADEOS was in a descending, Sun synchronous orbit with a nominal equatorial crossing time of 10:30 a.m. Amoung the instruments carried aboard the ADEOS spacecraft was the Ocean Color and Temperature Scanner (OCTS). OCTS is an optical radiometer with 12 bands covering the visible, near infrared and thermal infrared regions. (Eight of the bands are in the VIS/NIR. These are the only bands calibrated and processed by the OBPG) OCTS has a swath width of approximately 1400 km, and a nominal nadir resolution of 700 m. The instrument operated at three tilt states (20 degrees aft, nadir and 20 degrees fore), similar to SeaWiFS.

The proposed research is in response to the In-flight Biological Sample Preservation and Analysis topic and offers a non-invasive, proven, space and cost and time effective approach to biological sample collection and preservation. Our proposal is to collect capillary whole blood from the fingertip in addition to urine samples, and to store these samples as dried spots on a custom wick-matrix. The process of sample collection is minimally invasive to non-invasive, and samples can be stored efficiently at ambient temperatures during space flight. A wide array of blood analytes can already be determined from these samples, but in addition, we propose to develop and validate further assays that meet the specific objectives of NASA, its scientists and clinicians.

<p>There is an increasing need to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) to perform missions of vital importance to national security and defense, emergency management, science, and to enable commercial applications. However, routine access by UAS to the NAS remains unrealized.&nbsp;<br /><br />The UAS community needs routine access to the global airspace for all classes of UAS. Based on this need, NASA&#39;s UAS Integration in the NAS Project identified the following goal: To provide research findings to reduce technical barriers associated with integrating UAS into the NAS utilizing integrated system level tests in a relevant environment. These barriers include: a lack of sense-and-avoid concepts and technologies that can operate within the NAS, robust communication technologies, robust human systems integration, and a relevant environment for use in testing the developed technologies.<br /><br />The project&#39;s goal will be accomplished by developing system-level integration of key concepts, technologies and/or procedures, as well as demonstrating those integrated capabilities in an operationally relevant environment.&nbsp;<br /><br />The project conducts research to address technical&nbsp;barriers in the following areas:</p><ul><li>Sense and Avoid (SAA) [synonymous with Detect and Avoid (DAA)] Performance Standards: Provide research findings to develop and validate UAS Minimum Operational Performance Standards (MOPS) for SAA performance and interoperability.</li><li>Command and Control (C2) Performance Standards: Provide research findings to develop and validate UAS MOPS for terrestrial C2 communication.</li><li>Human Systems Integration (HSI): Provide research findings to develop and validate HSI ground control station (GCS) guidelines enabling implementation of the SAA and C2 performance standards.</li><li>Integrated Test and Evaluation (IT&amp;E): Develop a relevant test environment that is a live virtual constructive (LVC) distributed environment (DE), for use in generating research findings to develop and validate HSI guidelines, DAA, and C2 MOPS with test scenarios supporting integration of UAS into the NAS.</li></ul><p>These activities support research within the aeronautics strategic thrust area 6.&nbsp;</p>

Hardrock mining for gold and other metals is proposed for the Kensington Mine, located on Lynn Canal in Southeast Alaska, approximately 45 miles north of Juneau. The adjacent Jualin Mine is in the exploration phase. Over a tenyear period, various scenarios have been proposed for the Kensington Mine, including the cyanidation process to extract gold from crushed orebearing rock, a tailings pond for tailings disposal above anadromous fish streams, mixing zones for excess tailings water into fresh andor marine waters, dry upland tailings storage, and most recently, submarine tailings disposal, and onsite process water treatment. The Kensington Mine is located adjacent to marine waters that support large numbers of migratory waterfowl, salmon, and herring. There are few baseline data on metals in local organisms available to compare with later monitoring data if this and other mines become operational. The object of this study is to produce a set of data to be used as a predevelopment baseline for metal and cyanide concentrations in sediments and biota from potentially affected areas near Kensington and adjacent mining properties. Marine sediment was collected in 1994 from two coastal locations and blue mussels Mytilus trossulus were taken from six locations adjacent to the Kensington Mine site. Total metals and cyanide analyses were done for all samples. Dolly Varden Salvelinus malma and prickly sculpin Cottus asper were collected from Sherman and Sweeny Creeks, which flow through the Kensington Mine site. Metal concentrations in sediments mean concentrations in ppm dry weight DW: As 9.65, Cd 0.1, Cr 24.41, Cu 43.94, Hg 0.027, Ni 17.75, Pb 6.07, Zn 47.24 were comparable to other Southeast Alaska locations that have not been affected by human activities. Cyanide concentrations mean of 0.07 ppm DW were close to the level of detection in all marine sediment samples. Metal concentrations in blue mussels were also comparable to those in mussels from other Southeast Alaska locations with the exception of cadmium. Cadmium concentrations mean of 9.95 ppm DW were higher than any concentrations previously reported from Southeast Alaska mussels. Composite samples of Dolly Varden and sculpin arsenic concentrations 1.88, 1.37 ppm DW, respectively were higher than expected when compared to fish from other Southeast Alaska locations, but reflect naturally high arsenic levels reported in water from Sweeny and Sherman Creeks collected by Coeur Alaska. Other freshwater fish metal concentrations were similar to those reported in previous baseline studies from Southeast Alaska. These data will provide partial baseline data prior to any mine development.
