One of the major envisaged goals of the BepiColombo mission is to provide a lander with in-situ instrumentation onboard. The total delta-v required to land on the surface of Mercury is challenging and limits very strongly the payload mass, which can be landed safely and operated on the surface. Therefore it is required to perform an optimisation of the selected payload by a strong integration and miniaturisation of the payload elements to be able to fulfil the scientific requirements. For geochemical measurements mobility of the instrument(s), which can be provided by a small rover, is one of the top requirements. For measurements of the planetary heat flow and physical properties of the soil a subsurface penetrator is envisaged. Providing panoramic 3D-pictures from the surface in the close vicinity of the lander during night requires a camera mounted on a rotating mast and an appropriate illumination device. A magnetometer provides measurement of the local natural magnetic field. To cope with the stringent restriction on mass and power the instruments have to share the same data processing unit and central power supply and have to be fully integrated. During the talk the instruments and their optimisation and integration into the lander, which is done in the frame of the ESA BepiColombo mission are discussed. Alternative instrumentation and their possible integration will be shown as well.
