Description: 

During the course of the study a significant effort has been dedicated to the explorations of a very high number of configuration architectures for scenario (d), which definition became the main focus of the activity. Several hundreds of options have been analysed with a high level of detail both at mission analysis and mass budget level, to properly identify robust and feasible solutions.
The three of them make use of both staging and aero-braking to reduce the spacecraft wet mass, and they all rely either on chemical propulsion or on a mixed system combining a chemical engine with 2 very powerful electrical thrusters (ARM engines). This result is the consequence of the tight timelines imposed on the mission which do not leave any room to less powerful and more efficient electrical propulsion systems. To accommodate such demanding plan, the mission design is forced to assume certain risk like the ones associated with staging and aero-braking techniques.
