Zusammenfassung:	<jats:p>The primary goal of the Geospace Environment Modeling (GEM) program of the National Science Foundation (NSF) is the development of one or more comprehensive, physical, first principles model(s) of Earth's geospace environment. There are many needs for such models, including the codification of our understanding of the physical processes, as a tool for the analysis of single (or a few) spacecraft observations, and in an operational setting for the forecast of space weather, to name a few. The analogy with atmospheric sciences shows that such model development takes decades and that the quality of models mostly progresses in small, incremental steps. In the course of model development it is imperative to test the models frequently in real world scenarios in order to document the progress and to expose shortcomings.</jats:p>
