Space around Earth is influenced by the highly dynamic Sun with its transient explosive eruptions and its constantly outflowing solar wind. Spacecraft operate continually in these dynamic, and often adverse conditions which can lead to a variety of effects including radiation damage and electrical phenomena which, in extreme cases, can lead to entire spaceraft loss. The application of space environment models to mission preparation helps to limit the damage and enables experts to estimate the level of protection nesessary for spacecraft to meet their life-time requirements while avoiding over-design.
