The General Mission Analysis Tool (GMAT) is an open-source tool for space mission design and navigation. GMAT is developed by a team of NASA, private industry, and public and private contributors.
The GMAT development team is pleased to announce the release of GMAT version R2026a. For a complete list of new features, compatibility changes, and bug fixes, see the R2026a Release Notes in the Users Guide.
Simulation for spacecraft attitude control system analysis and design
42 is a comprehensive general-purpose simulation of spacecraft attitude and orbit dynamics. Its primary purpose is to support design and validation of attitude control systems, from concept studies through integration and test. 42 accurately models multi-body spacecraft attitude dynamics (with rigid and/or flexible bodies), and both two-body and three-body orbital flight regimes, modelling environments from low Earth orbit to throughout the solar system. 42 simulates multiple spacecraft...
Savors is a visualization framework that supports the ingestion of data streams created by arbitrary command pipelines. Any number of data streams can be shown synchronized by time in the same or different views, which can be arranged in any layout. These capabilities combined with a powerful parallelization mechanism and interaction models already familiar to administrators allows Savors to display complex visualizations of data streamed from many different systems with minimal effort.
Real-time interactive 3D graphics API for scientific simulations
...A simulation developer can use OpenFrames to specify what they want to visualize, without having to know any details of computer graphics programming.
OpenFrames is currently used by three NASA programs: Copernicus (NASA JSC), the General Mission Analysis Tool (GMAT, NASA GSFC), and a Virtual Reality exploration tool (NASA GSFC).
The TRANSIMS Studio application is an integrated development environment for the TRansportation ANalysis and SIMulation System (TRANSIMS). Components include a run time environment to execute TRANSIMS in parallel, as well as a full featured GUI.
A wildfire decision support system and visualization tool from Emxsys.
The Wildfire Management Tool (WMT) predicts the potential fire behavior of a wildland fire. WMT incorporates a 3D terrain viewer, the tenets of the Campbell Prediction System (CPS) and the Rothermel fire spread equations to depict fire behavior. WMT is used to adjust tactics & strategies to ensure the safety of firefighters and the effective use of firefighting resources.

JSatTrak is a Satellite tracking program written in Java. It allows you to predict the position of any satellite in real time or in the past or future. It uses advanced SGP4/SDP4 algorithms developed by NASA/NORAD to propagate the satellite orbits.
Metropolis is a visualization tool for TRANSIMS traffic simulation output. It specializes in viewing the dynamic outputs of the micro-simulator, such as vehicle motion and other time-varying data.
ViSBARD (Visual System for Browsing, Analysis, and Retrieval of Data) is an interactive visualization and analysis tool for space physics data. It provides an integrated 3-D/2-D environment to analyze measurements across many spacecraft and MHD models.
The Molwind project aims at developing Open Source software to visualize relationships among molecular entities such as chemical structures on the basis of NASA WorldWind. Different levels of complexity get visible by zooming in areas of interest.
growler is a C++-based distributed object and event architecture.
Its primary application has been in support of interactive, distributed visualization, "concurrent visualization", and computational steering.
Nodemon is a visualization tool for monitoring system resource utilization. It was developed for monitoring the Columbia supercomputer, a 10,240-processor Linux system at NASA Ames Research Center. It can monitor resources on any Linux system or cluster
