ESA’s Cluster spacecraft were in the right place at the right time on September 15, 2001. They flew through a region of the Earth’s magnetosphere at the exact moment that it reconfigured itself. The wealth of data will help scientists better model interactions between the Earth’s magnetosphere and the solar wind, as well as the magnetic fields around other stars and exotic objects with powerful magnetic fields.
