Brine Dewatering Using Ultrasonic Nebulization, Phase II
data.nasa.gov | Last Updated 2018-07-19T12:56:52.000Z
Recovery of water from brine is critically important for future manned space exploration. Resupply of water is prohibitively costly for such extended missions. Water reclamation processes typically recover 90-95% of the water present in wastewater formed by combining urine, hygiene water, and humidity condensate with the remaining concentrated in brine. This concentrated brine contains a significant amount of water, potentially a very valuable resource. The proposed prototype development will recover virtually all of the remaining water using an ultrasonic brine dewatering system (UBDS). In the UBDS process, extremely small nebulized droplets of the brine are created ultrasonically at the brine-air interface. Small droplets enable quicker drying due to their high relative surface area. This is particularly important when drying brines that contain thermally labile materials, which require relatively low temperature drying. The UBDS prototype has no nozzles to become plugged, requires little power, is simple and small, requires minimal astronaut attention and is compatible with continuous, closed cycle operation that can be made gravity independent. The innovative Phase 2 prototype will fulfill the unmet need to significantly improve water loop closure during extended manned missions. The Phase 2 project will provide an automated UBDS prototype that will be delivered to NASA for further testing.

A Silicon Carbide Foundry for NASA's UV and High Temperature CMOS Electronics Needs, Phase II
data.nasa.gov | Last Updated 2018-07-19T07:45:39.000Z
CoolCAD Electronics has developed a patent-pending technology to design and fabricate Silicon Carbide (SiC) MOSFET opto-electronic integrated circuits (ICs). We both fully design and fabricate these SiC Opto-Electronic ICs in the U.S. using our own design methodologies, SiC process recipes and in-house fabrication facility. We will design, fabricate and test SiC Extreme, Vacuum and Deep Ultraviolet photodetectors. We will prototype PN Junction and Schottky barrier linear photodiodes, as well as low dark count avalanche photodiodes. We will design and fabricate a two-dimensional 256 by 256 passive UV SiC focal plane array. Array elements will be fabricated in-house, out of both PN junction and Schottky barrier detectors, using CoolCAD's process and facilities. We will design and fabricate opto-electronic integrated circuits, where we will integrate various types of detectors with a MOS operational amplifier into a single IC to actively convert the photo current to usable voltage levels. We will also design and fabricate an integrated photodetector and 3-Transistor pixel for active readout. Multiple active pixel readout 3-T circuits will be an array to form a SiC active pixel MOS Deep UV imager. Our in-house fabrication process will also be upgraded. We will automate optical alignment to improve our microfabrication resolution and reduce minimum feature size. We will perform gate oxide anneals to improve carrier mobility. Improving mobility and reducing the minimum feature size will increase MOSFET performance and increase speed of opto-integrated circuits. Furthermore, SiC allows for optoelectronic operation at high temperatures. We will test our circuits up to 500C and utilize special metal contact stacks to enhance high temperature reliability. Finally, we will make our in-house process available to NASA and provide a process development kit for use of our fabrication facility to prototype new application specific SiC integrated circuits.

Goddard Satellite-Based Surface Turbulent Fluxes, 1x1 deg Daily Grid, Set1 V2c (GSSTF) at GES DISC
data.nasa.gov | Last Updated 2019-04-22T02:52:42.000Z
These data are the Goddard Satellite-based Surface Turbulent Fluxes Version-2c (GSSTF2c) Dataset recently produced through a MEaSUREs funded project led by Dr. Chung-Lin Shie (UMBC/GEST, NASA/GSFC), converted to HDF-EOS5 format. The stewardship of this HDF-EOS5 dataset is part of the MEaSUREs project. GSSTF version 2b (Shie et al. 2010, Shie et al. 2009) generally agreed better with available ship measurements obtained from several field experiments in 1999 than GSSTF2 (Chou et al. 2003) did in all three flux components, i.e., latent heat flux [LHF], sensible heat flux [SHF], and wind stress [WST] (Shie 2010a,b). GSSTF2b was also found favorable, particularly for LHF and SHF, in an intercomparison study that accessed eleven products of ocean surface turbulent fluxes, in which GSSTF2 and GSSTF2b were also included (Brunke et al. 2011). However, a temporal trend appeared in the globally averaged LHF of GSSTF2b, particularly post year 2000. Shie (2010a,b) attributed the LHF trend to the trends originally found in the globally averaged SSM/I Tb's, i.e., Tb(19v), Tb(19h), Tb(22v) and Tb(37v), which were used to retrieve the GSSTF2b bottom-layer (the lowest atmospheric 500 meter layer) precipitable water [WB], then the surface specific humidity [Qa], and subsequently LHF. The SSM/I Tb's trends were recently found mainly due to the variations/trends of Earth incidence angle (EIA) in the SSM/I satellites (Hilburn and Shie 2011a,b). They have further developed an algorithm properly resolving the EIA problem and successfully reproducing the corrected Tb's by genuinely removing the "artifactitious" trends. An upgraded production of GSSTF2c (Shie et al. 2011) using the corrected Tb's has been completed very recently. GSSTF2c shows a significant improvement in the resultant WB, and subsequently the retrieved LHF - the temporal trends of WB and LHF are greatly reduced after the proper adjustments/treatments in the SSM/I Tb's (Shie and Hilburn 2011). In closing, we believe that the insightful "Rice Cooker Theory" by Shie (2010a,b), i.e., "To produce a good and trustworthy 'output product' (delicious 'cooked rice') depends not only on a well-functioned 'model/algorithm' ('rice cooker'), but also on a genuine and reliable 'input data' ('raw rice') with good quality" should help us better comprehend the impact of the improved Tb on the subsequently retrieved LHF of GSSTF2c. This is the Daily (24-hour) product; data are projected to equidistant Grid that covers the globe at 1x1 degree cell size, resulting in data arrays of 360x180 size. A finer resolution, 0.25 deg, of this product has been released as Version 3. The GSSTF, Version 2c, daily fluxes have first been produced for each individual available SSM/I satellite tapes (e.g., F08, F10, F11, F13, F14 and F15). Then, the Combined daily fluxes are produced by averaging (equally weighted) over available flux data/files from various satellites. These Combined daily flux data are considered as the "final" GSSTF, Version 2c, and are stored in this HDF-EOS5 collection. There are only one set of GSSTF, Version 2c, Combined data, "Set1" The "individual" daily flux data files, produced for each individual satellite, are also available in HDF-EOS5, although from different collections: GSSTF_Fxx_2c, where Fxx are the individual satellites (F08, F10, etc..) The input data sets used for this recent GSSTF production include the upgraded and improved datasets such as the Special Sensor Microwave Imager (SSM/I) Version-6 (V6) product of brightness temperature [Tb], total precipitable water [W], and wind speed [U] produced by the Wentz of Remote Sensing Systems (RSS), as well as the NCEP/DOE Reanalysis-2 (R2) product of sea skin temperature [SKT], 2-meter air temperature [Tair], and sea level pressure [SLP]. Relevant to this MEaSUREs project, these are converted to HDF-EOS5, and are stored in the GSSTF_NCEP_2c collection. Please use these

Next Generation Neutron and Gamma-Ray Spectrometer for Planetary Spacecraft
data.nasa.gov | Last Updated 2018-09-07T17:42:54.000Z
We propose to develop a passive and active source neutron and gamma-ray spectrometer to characterize the abundance of near-surface hydrogen and rock-forming elements on a variety of spacecraft missions to planetary bodies (Moon, Mars, NEOs, comets). The instrument (initially at TRL-2) will use a new type of scintillator, Cs2YLiCl6:Ce (CLYC). CLYC is self-annealing at room temperature and provides both high efficiency detection of neutrons and excellent energy resolution for gamma-rays. The proposed work will investigate the use of a CLYC scintillator with a cosmic-ray background source as well as with an active pulsed neutron generator (PNG) source of neutrons for geochemical analysis. Our goal is to progress the overall instrument package (detector and PNG) to TRL-4. The ability of CLYC to detect both neutrons and gamma-rays (with a photomultiplier tube) has been demonstrated via a previously awarded NASA SBIR to RMD, thus we assert CLYC at TRL-3. The use of CLYC with a PNG is at TRL-2, and our proposal will develop timing-based electronics for the coupled system and perform testing in a laboratory environment, resulting in an overall instrument at TRL-4. Description of Methodology to be used: Task 1: Monte-Carlo modeling to determine optimal detector size based on minimum planetary radius and mission parameters as well as a science trade study of D-D vs. D-T pulsed neutron source with variable pulse rates and length. Task 2: Development of methods for maintaining high-performance characteristics of a CLYC detector in the space environment. Task 3: Development of integrated detector and electronics modules capable of operating in both passive and active source modes. Task 4: Testing of the integrated detector and electronics system with an isotopic and pulsed neutron source. Description of Relevance to PICASSO: This work supports the goals of PICASSO as it increases the TRL of a platform-independent (orbital or surface) instrument that is well suited for several medium-class planetary missions in NASA's Decadal Survey. For example, several science mission objectives specifically referred to by NASA are geochemical characterization during a comet sample return mission, a Trojan Tour and Rendezvous mission, and a rover-based Lunar South Pole-Aitken Basin sample return mission. The geochemical data provided by this instrument would directly address NASA's goals and objectives to 'characterize the chemical composition of comets', and to 'determine water resources in lunar polar regions and near-Earth asteroids'.

Compact High Efficiency GaN-based PPU, Phase I
data.nasa.gov | Last Updated 2018-09-07T17:39:50.000Z
Busek proposes to develop a low-cost, lightweight Hall Effect Thruster (HET) Power Processing Unit (PPU) at targeted 1kW/kg power density with more than 97% efficiency. The proposed PPU solution adopts advanced GaN power MOSFETs and PCB based planar magnetics technology to enable high switching frequency operation. Reduced headcount of magnetics, semiconductors and associated driver integrated circuits will allow for significant size reduction of all passive components to support ultra-high power density designs. This innovation will further miniaturize HET PPUs from today’s state-of-art by an anticipated 30% in volume and mass, with cost reductions exceeding 50% versus SOA solutions. The unique advantages of the proposed system can be summarized in three parts. First, the system utilizes a novel single-core multi-port circuit topology which integrates all the PPU subsystems through a single stage power conversion using a single multi-winding transformer. This significantly reduces system volume, weight, and cost. Second, the power flow control for each subsystem is fully independent regardless of power stage sharing. Each subsystem has its own phase shift control to regulate the desired output voltage and current. Third, the proposed PPU circuit topology is essentially a soft-switching DC-DC converter which can ensure zero-voltage-switching operation for all the switching devices. The proposal adopts the advanced GaN power MOSFETs and PCB based planar magnetics technology to enable high switching frequency operation, which supports a 30% size reduction of magnetics and other passive components in the high-efficiency and high-power density design. In Phase II Busek will characterize the breadboard PPU with sub-kilowatt Hall thrusters and develop a proto-flight brass-board level unit using GaN devices. At the conclusion of Phase II, Busek will deliver a PPU to NASA for additional characterization testing.
