Distributed, Fast, Intelligent Infrastructure Health Monitoring System

Improve operation and reduce maintenance costs with intelligent systems. Stennis Space Center, Mississippi NASA needed an innovative solution to conduct system assessments of frameworks and to characterize subsystems of interest. This tool would be required to determine anomalies; examine their causes (root-cause analysis); make predictive statements (prognostics); provide intelligent health monitoring with incremental knowledge for working with unknown scenarios; and provide maintenance support for a complex collection of systems, subsystems, and elements in rocket engine test platforms.

Net Radiation and Evapotranspiration (Rn/ET) Download Product Tools and Interfaces

NASA’s Jet Propulsion Laboratory, Pasadena, California This toolset automates downloads of global, multi-year Moderate Resolution Imaging Spectroradiometer (MODIS) and related data necessary for performing net radiation and evapotranspiration (Rn/ET) modeling, and provides an application programming interface (API) for simple and reliable access of these data from Python or MATLAB applications. Several useful utilities for validating and curating/indexing the downloaded data are also included.

Software Tools for Fault Management Technologies

Marshall Space Flight Center, Alabama Several key areas of improvement in effect design, development, verification, and validation of fault management processes have been identified in NASA’s Fault Management Handbook. The majority of these guidelines are focused on making the modeling tools more user friendly and reducing the modeling cost and time, as well as enhancing the analytic capabilities.

Tool to Analyze a Leaking Source of Saturated Ammonia

Lyndon B. Johnson Space Center, Houston, Texas Containers of ammonia are used to supply cooling to different modules of the International Space Station. Each container has an attachment piece used to extract the ammonia. The attachment piece may allow ammonia to exit when not connected, and may also allow ammonia to exit to an outside area even when connected. The ammonia that has exited the container may accumulate in different compartments of the spacecraft. The ammonia is not desirable when accumulated in a compartment with a certain concentration.

Mixed-Integer Convex Programming Algorithm for Constrained Attitude Guidance

NASA’s Jet Propulsion Laboratory, Pasadena, California A general problem in spaceflight since its beginning is attitude guidance: how to turn a spacecraft — also called a slew — so as to point science instruments at their targets. The slew must be done while avoiding pointing sensitive science instruments (e.g., a camera) and attitude sensors (e.g., a star tracker) at bright objects in the sky (e.g., the Sun or the Moon).

A Robust, Real-Time Collaboration Technology for Decision Support using Common Operating Picture (COP) Environments

This software provides remote geobrowser control for collaborative decision-making. Stennis Space Center, Mississippi StormCenter Communications, Inc. software takes advantage of cloud computing solutions to solve the growing need for real-time collaboration when accessing a Common Operating Picture (COP) from any device without having to give up all the vital tools and display functionality; all this is performed without disrupting current workflows. A COP is a platform shared by multiple stakeholders to provide a single, identical display of relevant operational information (i.e., mapping information, network operations and cyber security, sensors, weather, critical infrastructure) and tools to mark and manipulate the data. In the era of Big Data and the need for improved decision-making with the presence of multiple stakeholders across different disciplines, collaboration when using a COP is essential to success. This is especially important when dealing with decision-makers who are frequently non-data experts who need to take action immediately based on their situational awareness.

Products of Tomorrow: April 2016

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.
