IMPACT is one of the STEREO mission's four measurement packages whose principal objective is to understand the origin and consequences of coronal mass ejections (CME's). CME's are the most energetic eruptions on the Sun. They are responsible for essentially all of the largest solar geomagnetic storms. In order to understand and forecast CME's, we need 3-Dimensional images of them and of the ambient solar corona and heliosphere.
