This artist’s impression provides an exploded view of a Souyz 2B rocket with a Fregat upper stage mounted on top. This rocket will set BepiColombo into space in August 2015.
Visible in the launcher fairing is the BepiColombo ‘stack’, consisting of the Mercury Planetary Orbiter (MPO), the Mercury Magnetospheric Orbiter (MMO), and the transfer module, all mounted on top of Fregat.
