  Despite the close relationship between planetary science and plasma physics,
few advanced numerical tools allow to bridge the two topics. The code Menura
proposes a breakthrough towards the self-consistent modelling of these
overlapping field, in a novel 2-step approach allowing for the global
simulation of the interaction between a fully turbulent solar wind and various
bodies of the solar system. This article introduces the new code and its 2-step
global algorithm, illustrated by a first example: the interaction between a
turbulent solar wind and a comet.
