A model describing supercritical-pressure, multi-species turbulent mixing has been developed to simulate situations prevailing in diesel, gas turbine, and HCCI (homogeneous charge compression ignition) engines. It is also a situation occurring in atmospheric planetary science,...

Elementary-reaction chemical kinetics of hydrocarbon oxidation consists of hundreds to thousands of species and thousands of reactions. As such, it is impossible to use it in models and codes involving turbulence because computations are unfeasible due to lack of memory and...

The FAA, using its CARI-6 program, provides galactic cosmic radiation dosage rates for any location on the Earth from ground up to 60,000 ft (≈18,300 m). One way to protect astronauts from galactic cosmic radiation (GCR) on a Mars mission is to use...

The iSWA system is a Web-based dissemination framework for NASA-relevant space weather information that combines forecasts based on the most advanced space weather models with concurrent space environment information. A key design driver for the iSWA system is to generate and present vast amounts of...

Mars Science Laboratory (MSL) surface operations require precise and accurate knowledge of rover position. A key means of establishing/verifying position is to match ortho-rectified mosaics from the MSL onboard cameras to orbital data. Manual localization by matching mosaics to HiRISE...

The SAM/MSL Terrestrial Background Spectral Library is one of the tools developed for identifying known terrestrial background for the Mars Science Laboratory (MSL) Sample Analysis at Mars (SAM) mission. The SAM instrument suite can detect trace elements in the ppb range and therefore requires a...

Spaceflight and planetary exploration place severe constraints on the available bandwidth for downlinking large hyperspectral images. Communications with spacecraft often occur intermittently, so mission-relevant hyperspectral data must wait for analysis on the ground before it can inform...

Web Sockets is a network full-duplex communication channel that allows Javascript programs embedded in Web pages to establish connections to applications running on the server that provided the Web pages. Two-way communication is...

A mobile device application created by NASA visualizes recent global climate data from Earth science satellites, including air temperature, sea surface salinity, carbon monoxide, ozone, and water vapor, as well as gravity and sea level variations. This app is an Open GL simple 3D object viewer for the Apple IOS and...

Mixed-initiative teams of robots and humans working side-by-side in close proximity to each other need to be capable of reasoning about the actions and activities of each other within a mission context. This capability requires the robotic agents to have a sense of self, and their...

This software enables one to calculate elevation-dependent relative air mass. When imaging a setting or rising Sun on the ground or from space, the shape and the intensity distribution of a captured image are affected by the following three...

A software program analyzes data measured by the Vehicle Cabin Atmosphere Monitor (VCAM) and quantifies the concentrations of trace chemicals detected by VCAM. The software contains a unique way to quantify the signal measured by VCAM, to establish the concentration curve,...

MAPS is a suite of software tools used for pre-flight planning, real-time support, and post-flight analysis of spacecraft attitude and pointing for the International Space Station (ISS), HII Transfer Vehicle (HTV), Automated Transfer Vehicle (ATV), and other low Earth orbit (LEO)...

Documents, such as reports that are consistent in format, are excellent candidates for automation. Autodoc was designed as a means to automate such reports in order to reduce the amount of labor necessary to produce reports, and to improve the accuracy...

The Exploration Visualization Environment (EVE) is a graphical environment for the visualization, analysis, and simulation of engineering data, specializing in aerospace and aeronautic concepts. EVE is based on the history and successful application of the Synergistic Engineering Environment (SEE) and provides...

For Orion Exploration Flight Test One (EFT-1), the unit-under-test for flight software verification has been chosen as the entire integrated flight software load. At the time of this reporting, the unit test tool, while powerful, operates on very small units, usually classes. This leaves a sizable...

A software simulator was developed to simulate data flow from the Interface Data Processing Segment (IDPS) to the Science Data Segment (SDS) for the NPOESS Preparatory Project (NPP) via multiple Secure FTP (sftp) connections. The simulator is a multi-threaded Java program that handles the...

GPS radio occultation measurements are vital for climate monitoring and atmospheric temperature change detection. However, the data are irregularly distributed in space and time, which makes it inconvenient for many applications.

To reduce the cost of building specialized interfaces, missions can adopt Goddard Mission Services Evolution Center (GMSEC) technologies and applications. Assurances need to be made that application implementation should follow the GMSEC messaging standards. The GMSEC Interface...

The NASA Experiment Designer (NED) is a client-server application that enables end-to-end support for driving long-running scientific computer simulations such as climate and weather models. The tool provides a friendly, single point of entry for configuring parameters associated...

This software was designed to automate delivery of tasking requests to a central queue, enabling integrated observation scenarios across multiple assets. It is a JAVA code application that enables machine-to-machine access between a client platform and the Campaign Manager application program interface (API) to...

This library provides an abstraction layer that an end user can access, interpolate, and perform fieldline integration for space weather simulation data. Normally, accessing and interpolating space weather simulation data requires knowledge of...

Lossless data compression has been employed in space to reduce communication bandwidth requirements for onboard storage for more than 15 years. A widely used space compression standard is the recommendation published by the Consultative Committee on Space Data Systems (CCSDS). The standard describes a simple,...
