TIE: The Imagery Exchange for the NASA Global Imagery Browse Services (GIBS) Project

The NASA Earth Observing System Data and Information System (EOSDIS) is a data-centric system designed for processing and archiving from NASA’s Earth Observation missions and their distribution, as well as provision of specialized services to users. The major components of EOSDIS are 12 Distributed Active Archive Centers (DAACs), 14 Science Investigator-led Processing Systems (SIPSs), and the EOS Clearing House (ECHO). The Global Imagery Browse Services (GIBS) is the value-added image archive and access service for NASA Earth Science data products. It is the high-resolution global imagery solution for NASA. As the central imagery hub, GIBS is in need of an automated, scalable imagery capturing and generation solution.

Space Communications and Navigation (SCaN) Game Phase III

The Space Communications and Navigation (SCaN) program is responsible for providing communications and navigation services to spaceflight missions located throughout the solar system. Astronauts, mission controllers, and scientists depend upon the reliable transmission of information between Earth and spacecraft in low Earth orbit (LEO) or deep space.

Adverse Condition and Critical Event Prediction Toolbox (ACCEPT)

One of the main features is the relaxation of the technical conditions required for robust early detection of the onset of adverse events.Many natural or complex engineered systems rely upon critical functions or processes that can be measured with the aid of various sensors or other novel devices. As a result, sensor and measurement data can be used to learn a parametric or non-parametric model of the behavior for a given process or metric. For such processes or metrics, it may be critical to avoid or be forewarned of impending level crossings that may characterize entry into extreme or potentially catastrophic operating regimes. Under certain circumstances, the metric to be monitored may represent the residual, or difference between an actual value and a predicted value generated by an independent regression method, rather than a physical process having a physically interpretable meaning.

MATLAB Webification Science Client

The Matlab Webification Science Client consists of several functions that access remote w10n-sci repositories to retrieve data. It supports user sessions to authenticate and authorize access to restricted repositories. In command line mode, it can list the contents of a w10n-sci node, change to other nodes, and retrieve data in chunks or as entire files. Command line mode facilitates batch processing of w10n-sci data by embedding these functions in custom MATLAB scripts.

Software Models Electromagnetics of Wireless Power Transfer

Imagine coming home and dropping your phone, laptop, and Bluetooth® headset on your kitchen table so that they all recharge simultaneously. What if you could drive your electric car into a garage, park above a mat, and know it will be charged in the morning? What if there was a new medical implant to replace the one you wear — and the new version does not include power cords or the need to replace batteries?

Improving Weapons with Simulation

As engineers design new weapons or modify existing ones, reducing time and money on development can be critical in providing soldiers with improved weapons without undue delay. A new sight may be planned for the M4 rifle, but how well does a prototype design work, and where would be the best place to mount it for the best accuracy and ease of use? Or new, nonlethal weapons may be needed, but will they perform as expected at different ranges?

Simulating Material Migration

Accurately tracking and predicting the subsurface migration of specific materials over time and over multiple phases is critical to efficient and effective strategy development and deployment in a growing number of applications. STOMP (Sub surface Transport Over Multiple Phases) is a general-purpose tool that provides multidimensional analysis of subsurface flow and reactive transport phenomena. It was originally designed to support environmental remediation of subsurfaces contaminated with volatile organic compounds and/or radioactive material.
