Abstract:To achieve the capability to affordably produce scores of nano-spacecraft for envisioned constellation missions, a new manufacturing process is needed to reduce the time and cost of fabricating and testing the nanosats. However, to achieve substantial savings, a fundamental paradigm shift in how… more
Abstract:NASA has determined that the use of modular and reconfigurable components is critical for the success of future large and complex space systems. In order to achieve this goal, it is necessary to be able to assemble and reassemble modules both on the ground and on orbit. Therefore, it requires a… more
Abstract:Ground/shore based Test Range instrumentation systems tracking coverage are physically and geographically constrained by line-of-sight limitations while test items continue to increase in speed and range performance. A means to extend Test Range coverage is required to support increasingly… more
Abstract:72904-Aerosol particles have important impacts on visibility, acid deposition, climate, and human health, although large uncertainties remain on their quantification. A significant part of the anthropogenic aerosol is generated from energy-related activities, and organic compounds are known to… more
Abstract:72080-Nitrogen dioxide emissions are regulated by a national ambient air quality standard under the 1970 Clean Air Act. The prevalent means of detection, a chemiluminescence-based monitor (the so-called NOx box), often provides inaccurate readings for nitrogen dioxide in the presence of other… more
Abstract:AFRL/VSSS is the lead Air Force group providing the DoD community with physics-based predictive models critical to assessing the utility of EO/IR spectro-polarimetric sensing for aerospace reconnaissance and target cueing. AFRL/VSSS is presently upgrading the government-standard MODTRAN atmospheric… more
Abstract:Aerosol particles play an important role in visibility, acid deposition, climate, and human health, although large uncertainties remain in quantifying their impacts which depend on their chemical composition and atmospheric transformations. An innovative aerosol mass spectrometer (AMS)has been… more
Abstract:76321-Predictions of global warming caused by human activities rely on complex models, which include time variable sources and sinks of atmospheric gases such as carbon dioxide. Reliable modeling depends on the existence of accurate and frequently-taken atmospheric profiles of these greenhouse… more
Abstract:75422-The increase of atmospheric CO2 from fossil fuel combustion is a major contributor to global warming and climate change. Improved measurement technology for directly determining the exchange fluxes of the stable isotopes of CO2 is crucial to understanding the natural carbon cycle, which… more
Abstract:75716-Aerosol particles in the atmosphere have important effects on visibility, acid deposition, climate, and human health. A significant part of anthropogenic aerosols is generated from energy-related activities, and organic compounds are known to constitute a significant fraction of ambient… more
Abstract:This Small Business Innovation Research Phase II project addresses the need for improved monitoring technologies for continuous particulate mass and chemical speciation of ambient aerosols. Aerodyne Research, Inc. will develop a prototype Aerosol Chemical Speciation Monitor (ACMS) that measures… more
Abstract:75169-There is a need to monitor the efficiency of phytoremediation, in which green plants are used to extract and remove metals, radionuclides, and other contaminants from soil, subsurface sediments, or ground water. In particular, the concentration and partitioning of the contaminants in plant… more
Abstract:Communications security (COMSEC) role in space continues to grow as the available bandwidth expands. The DOD Transformational Communications (TC) vision will transform the space, air, and ground networks into a fully integrated internet-like network. This vision requires cryptographic… more
Abstract:The military and intelligence communities seek computing systems that can safely share information with different degrees of confidentiality. Systems achieving that goal are said to operate in multi-level mode, which indicates that the system contains information at several different levels of… more
Abstract:High-power Hall thrusters operating at high thrust-to-power ratios will consume and emit unprecedented amounts of xenon propellant. The inherent costs associated with xenon use have significantly hindered development of such devices. Metallic propellants, specifically bismuth, have recently… more
Abstract:Testing of high energy weapons systems in wind tunnels carries high risk due to the destructive power of the laser.

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
