 These instruments would be operated during the approach, hovering and descent phases for science purpose, for landing site selection and for spacecraft safety during near-surface manoeuvres.The Lander would have its own payload for the characterization of the "in situ" measurements (e.g., close-up camera, panoramic camera, electron microscope, X-ray diffractometer, volatile detector, microbalance, mass spectrometer).Instruments on the lander would be operated "in-situ" through automatic or Earth commanded sequences.
