2D In situ measurements

An extensive payload is proposed for MarcoPolo-2D.  This is required to gather information to:

• Permit safe close proximity operations (i.e. sampling)
• Identify highest science value potential sampling and landing sites
• Provide geological context for the sample
• Undertake fundamental research about the physical and chemical nature of the asteroid.

Mapping at various wavelengths from visible through to mid infra-red will required, with a range of spatial resolution down to <cm.  Chemical analysis of evolved species and chemical variation on the surface with a focus on more volatile components will be performed.  The internal structure will be investigated by a number of experiments, including various radar instruments as well as shape and mass characterisation.  Regolith properties and structure will also be explored, in order to provide additional understanding to the ground truth for remote spectral observation.
