Published By National Aeronautics and Space Administration
Issued over 9 years ago
Summary
Description
PI at ArkLight proposes to implement photon counting detectors at near-IR (1-1.8 microns) and mid-IR (3-4 microns) with single photon sensitivity based on frequency up-conversion during Phase 2, representing an innovative Lidar technology for ASCENDS mission. By working with Prof. Ding at Lehigh University, PI will explore fundamental limits to quantum efficiencies for up-conversion detection at 1.57 microns. She will implement, characterize, and optimize single up-conversion device capable of detecting 1.57 microns and 1.27 microns. She plans to achieve detections of CO2 and O2 using implemented up-conversion device. She will investigate fundamental limits to noises for up-conversion detections. She will compare among PPLN, PPKTP, and PPLT as up-conversion media. She will expand detection wavelengths to cover ranges of 1-1.8 microns and 3-4 microns. She plans to introduce novel techniques for improving performances of up-conversion devices. She will investigate versatility of up-conversion devices under harsh environments. To achieve all these objectives, she has laid out a detailed work plan describing all the specific tasks necessary. Through optimizations, she will achieve the quantum efficiency of 50%, dark count rate of 50 Hz, bandwidth of GHz, electrical consumption of < 1 W, weight of < 1 lb, and dimension of 7x4x4 (all in inches).

Description
Aircraft icing continues to be one of the major safety and operational concerns of the FAA, elements of the military, and the foreign military and civilian counterparts. Attempts to develop methods to directly detect aircraft icing meteorological conditions have met with mixed success. Combining microwave radiometers with radars has shown great promise, but deficiencies of the radiometers have limited their value. In this proposed effort we will develop a fast sampling multifrequency profiling and dual polarization narrow beam radiometer system to overcome these deficiencies. In this proposed radiometer system, all beams are collinear and match the antenna gain pattern of weather research radars. The radiometer will have the capability of profiling (ranging) water vapor along the beam as well as discriminate ice and water phase hydrometeors. We will also develop a fast beam steering system to operate in concert with the radar. Phase II will produce a turnkey radiometric system, ready to deploy.

Description
Busek proposes to develop light metal Hall Effect thrusters that will help reduce the travel time, mass, and cost of SMD spacecraft. Busek has identified three attractive light metal propellants: magnesium (Mg), zinc (Zn), and a eutectic (Mg/Zn). These metals are plentiful and practical alternatives to Xe and Kr, which are expensive and scarce, and Bi, which is overly condensable and requires a high voltage power processing unit (PPU) to reach velocities of interest. Because Mg and Zn are lightweight, specific impulse > 3000 s will be available with a near term, low voltage PPU, decreasing propellant mass and program and hardware costs. Both metals have favorable ionization properties, implying high efficiencies are possible. Mg can also be combusted with water in a rocket, enabling a multi-mode propulsion system where the Hall thruster and rocket share propellant. The availability of a high thrust impulsive mode can greatly decrease delta V and trip times for SMD spacecraft. These light metals are non-toxic and solid at room temperature. They can be stored and fed to a thruster as a wire. For Zn and Mg/Zn, liquid distribution is also feasible. Life testing will be low cost because the light metals are inexpensive and self pumping; they will condense on the vacuum chamber wall. Vapor pressure curves suggest minimal spacecraft interactions. In-situ propellant production is also possible. Mg, for example, can be extracted from Martian regolith using solar energy. The key innovation in this proposal is the use of light metals to fuel a Hall thruster. In Phase I, Busek will design and demonstrate a wire based light metal feed system that will be integrated with an existing 1-2 kW bismuth vapor Hall Effect thruster. Busek will then demonstrate a Mg, Zn, or Mg/Zn discharge and measure its operating parameters. Finally, Busek will lay out a dedicated thruster and feed system to be built and tested in Phase II.

Description
<p>Using biologically-inspired neuromorphic optic flow algorithms is a novel approach in collision avoidance for UAS. Traditional computer vision algorithms rely on solving nonlinear partial differential equation systems to estimate optic flow which is a computationally expensive task. Neuromorphic algorithms instead make use of lessons learned in biology to solve these problems in a more efficient manner. An example is the fly&#39;s motion detector, which can be modeled by a system that uses a set of locally calculated, parallel spatio-temporal correlations for a set of velocities determined by the input sampling rates and flying speeds. Correlation results are interpreted as likelihood for a motion direction and speed. Stages of obstacle detection and tracking can temporally and spatially integrate these likelihoods to increase the signal-to-noise ratio, and in turn the detection rate. In addition to its computational efficiency, the proposed neuromorphic solution is more stable and noise tolerant than solving a nonlinear optimization problem. Even if single computational nodes get corrupted due to functional or structural failures in the hardware, the performance of appropriately designed parallel, distributed neuromorphic algorithms degrades gracefully. Neuromorphic algorithms are commonly implemented using software running on general-purpose multicore/graphic processing unit systems. This approach, though flexible, can have significant overhead in terms of power, performance, and is not easily portable across platforms, therefore reducing its scope of applicability. In the second phase, we will port the neuromorphic algorithms to field programmable gate arrays (FPGAs) and application specific integrated chips (ASICs). This will allow us to meet demanding performance requirements needed in UAS such as fast processing, low weight, low power consumption, as well as robustness to hardware failure.</p>

The Total Solar Irradiance (TSI) data set SOR3TSID contains the total solar irradiance (a.k.a solar constant) data collected by the Total Irradiance Monitor (TIM) instrument covering the full wavelength spectrum averaged at daily intervals. The data are normalized to one astronomical unit (1 AU). The TIM instrument measures the Total Solar Irradiance (TSI), monitoring changes in incident sunlight to the Earth's atmosphere using an ambient temperature active cavity radiometer to a designed absolute accuracy of 100 parts per million (ppm, 1 ppm=0.0001% at 1-sigma) and a precision and long-term relative accuracy of 10 ppm per year. Due to the small size these data and to maximize ease of use to end-users, each delivered TSI product contains science results for the entire mission. Updates to Level 3 TSI data occur monthly in order to reduce repeated delivery of data.

Summary
Description
Mean depth was calculated from the bathymetry surface for each cell using the ArcGIS Spatial Analyst Focal Statistics "Mean" parameter. Mean depth represents the average depth value (in meters) within a square 3x3 cell window. The 2x2 meter resolution mean depth GeoTIFF was exported and added as a new map layer to aid in benthic habitat classification. Acoustic imagery was acquired for the VICRNM on two separate missions onboard the NOAA ship, Nancy Foster. The first mission took place from 2/18/04 to 3/5/04. The second mission took place from 2/1/05 to 2/12/05. On both missions, seafloor depths between 14 to 55 m were mapped using a RESON SeaBat 8101 ER (240 kHz) MBES sensor. This pole-mounted system measured water depths across a 150 degree swath consisting of 101 individual 1.5 degree x 1.5 degree beams. The beams to the port and starboard of nadir (i.e., directly underneath the ship) overlapped adjacent survey lines by approximately 10 m. The vessel survey speed was between 5 and 8 kn. In 2004, the ship's location was determined by a Trimble DSM 132 DGPS system, which provided a RTCM differential data stream from the U.S. Coast Guard Continually Operating Reference Station (CORS) at Port Isabel, Puerto Rico. Gyro, heave, pitch and roll correctors were acquired using an Ixsea Octans gyrocompass. In 2005, the ship's positioning and orientation were determined by the Applanix POS/MV 320 V4, which is a GPS aided Inertial Motion Unit (IMU) providing measurements of roll, pitch and heading. The POS/MV obtained its positions from two dual frequency Trimble Zephyr GPS antennae. An auxiliary Trimble DSM 132 DGPS system provided a RTCM differential data stream from the U.S. Coast Guard CORS at Port Isabel, Puerto Rico. For both years, CTD (conductivity, temperature and depth) measurements were taken approximately every 4 hours using a Seabird Electronics SBE-19 to correct for the changing sound velocities in the water column. In 2004, raw data were logged in .xtf (extended triton format) using Triton ISIS software 6.2. In 2005, raw data were logged in .gsf (generic sensor format) using SAIC ISS 2000 software. Data from 2004 were referenced to the WGS84 UTM 20 N horizontal coordinate system, and data from 2005 were referenced to the NAD83 UTM 20 N horizontal coordinate system. Data from both projects were referenced to the Mean Lower Low Water (MLLW) vertical tidal coordinate system. The 2004 and 2005 MBES bathymetric data were both corrected for sensor offsets, latency, roll, pitch, yaw, static draft, the changing speed of sound in the water column and the influence of tides in CARIS Hips & Sips 5.3 and 5.4, respectively. The 2004 data was then binned to create a 1 x 1 m raster surface, and the 2005 data was binned to a create 2 x 2 m raster surface. After these final surfaces were created, the datum for the 2004 bathymetric surfaces was transformed from WGS84 to NAD83 using the "Project Raster" function in ArcGIS 9.1. The 2004 surface was transformed so that it would have the same datum as the 2005 surface. The 2004 bathymetric surface was then down sampled from 1 x 1 to 2 x 2 m using the "Resample" function in ArcGIS 9.1. The 2004 surface was resampled so it would have the same spatial resolution as the 2005 surface. Having the same coordinate systems and spatial resolutions, the final 2004 and 2005 bathymetry rasters were then merged using the Raster Calculator function "Merge" in ArcGIS's Spatial Analyst Extension to create a seamless bathymetry surface for the entire VICRNM area south of St. John. For a complete description of the data acquisition and processing parameters, please see the data acquisition and processing reports (DAPRs) for projects: NF-04-06-VI and NF-05-05-VI (Monaco & Rooney, 2004; Battista & Lazar, 2005).
