Mercury Planetary Orbiter (MPO): ESA’s instrumental steward
It’s hard to pin down one specific instrument from the 16 that constitute BepiColombo, as each instrument is as important as the next. However, the ESA’s MPO orbiter holds 11 instruments that can unlock the secrets of Mercury’s elusive surface and composition.
With imagers, spectrographs and other hightech equipment, the MPO will undoubtedly show scientists Mercury’s past and its evolution into its current state, from the core to the magnetosphere. By using instruments that are tuned to look at Mercury in wavelengths unperceivable to the human eye, the nature of Mercury will be explored after BepiColombo’s arrival.
