The Exploration Visualization Environment (EVE) is a simulation, visualization, and analysis system designed to integrate engineering data with a virtual environment in support of the design and planning of space-based missions. Through the integration of time-dependent data with detailed graphical models within a full-scale three-dimensional solar system or independent reference frame, the analyst can gain valuable insight into the correlation of data with simulation events. EVE provides a rich set of navigation tools (both in time and space) to enable the user to analyze the data. EVE has been developed to run crossplatform under Linux, Windows, and Mac OS X, and draws upon the experience and use of the Synergistic Engineering Environment (SEE).

EVE has been developed to support the needs of engineers and scientists within spacecraft design and mission planning where a better understanding of the problem can be gained through the integration of data from multiple domains and sources. It is often necessary to analyze the behaviors or results of one analysis in one domain in the context of another domain or sets of domains, such as understanding the impacts on the payload unloading capabilities of a Lander design due to a higher deck height due to engine resizing. In addition, most of the time an analysis not only crosses these domains, but also crosses entire design teams. Therefore, it is often necessary to make sure that design teams are at the same level of understanding of an overall problem before each person can see how their specific detail is related to the overall problem.

EVE is built on several components, including a solar system model, spacecraft geometry representation models, geometry manipulation tools, dynamics propagators, data importers, report writers, image and animation capture modules, analysis modules, a data display management system, a navigation module, a time control module, and a graphical user interface suite.
