• To investigate the origin of the Solar System by studying the origin of comets.

• To study the relationship between cometary and interstellar material.

• Global characterisation of the cometary nucleus (dynamic properties, surface morphology, composition).

• Chemical, mineralogical and isotopic compositions of volatiles and refractories in a cometary nucleus.

• Physical properties and interrelation of volatiles and refractories in a cometary nucleus.

• Study of the development of cometary activity and the processes in the surface layer of the nucleus and the inner coma (dust-gas interaction).

• Global Characterisation of the asteroid (dynamic properties, surface morphology, composition).
