Remote Sensing Moisture Model Could Aid Farmers

Global farmers could get better decision-making help as refinements are made to North Alabama soil moisture modeling research being done by an atmospheric science doctoral student at The University of Alabama in Huntsville. The models indicate how much added moisture would be needed in a given area versus historical data to achieve various crop yields, and they could aid in making expensive infrastructure investments by helping to determine their economic viability.

NASA Model Provides 3-D View of L.A. Earthquake

On March 28, residents of Greater Los Angeles experienced the largest earthquake to strike the region since 2008. The magnitude 5.1 quake was centered near La Habra in northwestern Orange County about 21 miles (33 kilometers) east-southeast of Los Angeles, and was widely felt throughout Southern California. There have been hundreds of aftershocks, including one of magnitude 4.1.Scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif., have developed a model of the earthquake, based on the distribution of aftershocks and other seismic information from the U.S. Geological Survey.A new image based on the model shows what the earthquake may look like through the eyes of an interferometric synthetic aperture radar, such as NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR). JPL scientists plan to acquire UAVSAR data from the region of the March 28 quake, possibly as soon as this week, and process the data to validate and improve the results of their model. The UAVSAR flights serve as a baseline for pre-earthquake activity. As earthquakes occur during the course of this project, the team is measuring the deformation at the time of the earthquakes to determine the distribution of slip on the faults, and then monitoring longer-term motions after the earthquakes to learn more about fault zone properties.

Weekly Status Reporting & Approval Application Revision 2

The Weekly Status Reporting & Approval Application is a Web application that enables organizations to gather weekly or monthly (periodically) statuses electronically from all employees using a time-based process. Users input their status, which may include uploaded images, into previously agreed-to categories. The system provides an approval process that allows for forwarding of statuses up the organizational hierarchy by designated approvers. Approved statuses get put into a final downloadable report. Historical statuses can be downloaded in report form to get a year at a glance for individuals and groups.

CoolSPICE: SPICE Simulator for Cryogenic Electronics

Accurate assessment of circuits at cold temperatures is extremely difficult due to lack of models and tools that can simulate circuit behavior at cryogenic temperatures. A library of cryogenic temperature models was built, as well as a circuit simulator that can use those models and simulate complex circuits at temperatures as low as 4 K.

Telescience Resource Kit, Release 3

Release 3 of the Telescience Resource Kit (TReK) has become available. TReK 3 is a suite of application programs that can be used to monitor and control a payload aboard the International Space Station. TReK provides both local ground support system services and an interface to utilize remote services provided by the Payload Operations Integration Center.

Software Tools for Fault Management Technologies

The ability to detect, diagnose, and respond to faults and anomalies in a timely fashion is a major concern in space missions. Fault Management (FM) primarily concerns operational mitigations of spacecraft failures. Qualtech Systems worked towards development of software tools for facilitating FM by using TEAMS (Testability Engineering and Maintenance System) as the underlying platform. The software tools will aid in satisfying a large subset of FM objectives: Determining completeness and appropriateness of FM designs and implementations; decreasing the labor and time required to develop and test FM models and algorithms; improving visualization of FM designs and analytic results; aiding testing and V&V (verification and validation) of FM designs and determining residual risk resulting from incomplete coverage; and increasing reliability of FM systems are major areas of focus.

Data Acquisition and Processing Software — DAPS

DAPS was designed to support the DAWN-AIR project participating in the Genesis and Rapid Intensification Processes (GRIP) hurricane campaign. It controls the data acquisition system consisting of a scanner that directs the lidar beam, an inertial navigation system/GPS (INS/GPS) unit for monitoring aircraft motion, a DSP module, and serial and video modules while acquiring and processing lidar data in real time. DAPS was optimized to meet the project requirement: acquiring and processing more than 550,000 samples per second. DAPS was capable of managing such extensive computational loads without experiencing a single incident of crash or system failure during the entire 130 flight hours of the GRIP mission.
