A novel multispacecraft technique applied to Magnetospheric Multiscale (MMS) mission data collected in the Earth’s magnetosheath enables evaluation of the energy cascade rate solving the full Yaglom’s equation in a turbulent space plasma. The method differs from existing approaches in that (i) it is inherently three-dimensional; (ii) it provides a statistically significant number of estimates from a single data stream; and (iii) it allows for a direct visualization of energy flux in turbulent plasmas. This new technique will ultimately provide a realistic, comprehensive picture of the turbulence process in plasmas.
