The time-varying magnetic fields generated on ESA's BepiColombo Mercury Planetary Orbiter (MPO) spacecraft have been measured recently to assess their influence on the Mercury magnetometer (MERMAG) instrument. We describe the basic measurement setup and present as an example some early results from a Solar Array Drive Mechanism (SADM).
The origin of global magnetic fields in celestial bodies is generally ascribed to dynamo action by fluid motions in their electrically conducting interiors. Some objects – e.g. close‐in extra‐solar planets or the moons of some giant planets – are embedded in ambient magnetic fields which modify the generation of the internal field in these bodies. Recently, the feedback of the magnetospheric field...
The magnetometer (MAG) on the Mercury Planetary Orbiter (MPO) of the joint European–Japanese BepiColombo mission to planet Mercury is a low-noise, tri-axial, dual-sensor, digital fluxgate instrument with its sensors mounted on a 2.8-m-long boom. The primary MPO/MAG science objectives are to determine the spatial and temporal structure of the magnetic field in the Hermean system, in particular the...
