Magnetospheric Orbiter Sunshield and Interface Structure (MOSIF) shaker test
The Proto-Flight Model (PFM) of the BepiColombo Mercury Magnetospheric Orbiter Sunshield and Interface Structure (MOSIF) being lifted by an overhead crane for installation on the electrodynamic multishaker in the Test Centre at ESA's European Space Research and Technology Centre (ESTEC) in Noordwijk, the Netherlands on 28 September 2011. MOSIF is being prepared for the lateral vibration tests that will qualify it for the dynamic mechanical environment specified by the launcher authority.
MOSIF will shield the Mercury Magnetospheric Orbiter (MMO) from the Sun during the journey to Mercury and provide the mechanical and electrical interfaces between the MMO and the Mercury Planetary Orbiter (MPO).
