  Using observational data from the \emph{Magnetospheric Multiscale} (MMS)
Mission in the Earth's magnetosheath, we estimate the energy cascade rate using
different techniques within the framework of incompressible magnetohydrodynamic
(MHD) turbulence. At the energy containing scale, the energy budget is
controlled by the von K\'arm\'an decay law. Inertial range cascade is estimated
by fitting a linear scaling to the mixed third-order structure function.
Finally, we use a multi-spacecraft technique to estimate the
Kolmogorov-Yaglom-like cascade rate in the kinetic range, well below the ion
inertial length scale. We find that the inertial range cascade rate is almost
equal to the one predicted by the von K\'arm\'an law at the energy containing
scale, while the cascade rate evaluated at the kinetic scale is somewhat lower,
as anticipated in theory~\citep{Yang2017PoP}. Further, in agreement with a
recent study~\citep{Hadid2018PRL}, we find that the incompressive cascade rate
in the Earth's magnetosheath is about $1000$ times larger than the cascade rate
in the pristine solar wind.
