Planetary Exploration Horizon 2061 Report, Chapter 3: From Science Questions To Solar System Exploration
(Centre) Radial distribution of Solar System objects (Logarithmic scale in AU) showing their diversity (planets, small bodies, dwarf planets and moons) and their distribution over 5 orders of magnitude in distance from the Sun, from slightly more than 0.1 AU to over 104 AU – still only a few percent of our distance to the closest stars. (Upper and lower panels) The main secondary systems of the Solar System display an equally broad diversity of architectures: gas giant systems (top), ice giant systems (bottom) contrast with the very different configuration of the Earth-Moon system. © NASA and ESO. — astro-ph.IM

This chapter of the Planetary Exploration Horizon 2061 Report reviews the way the six key questions about planetary systems, from their origins to the way they work and their habitability, identified in chapter 1, can be addressed by means of solar system exploration, and how one can find partial answers to these six questions by flying to the different provinces to the solar system: terrestrial planets, giant planets, small bodies, and up to its interface with the local interstellar medium.

It derives from this analysis a synthetic description of the most important space observations to be performed at the different solar system objects by future planetary exploration missions. These observation requirements illustrate the diversity of measurement techniques to be used as well as the diversity of destinations where these observations must be made. They constitute the base for the identification of the future planetary missions we need to fly by 2061, which are described in chapter 4.

Q1- How well do we understand the diversity of planetary systems objects?
Q2- How well do we understand the diversity of planetary system architectures?
Q3- What are the origins and formation scenarios for planetary systems?
Q4- How do planetary systems work?
Q5- Do planetary systems host potential habitats?
Q6- Where and how to search for life?
