A study based on data collected by these missions has estimated how much energy is transferred from larger to smaller scales within the magnetosheath, revealing that turbulence is the key, making this process a hundred times more efficient than in the solar wind.

The study included several years of data from four Cluster spacecraft and two THEMIS spacecraft.
