Missions to triple asteroids

In this talk, I will present the activities developed in the Instituto Nacional de Pesquisas Espaciais (INPE) in Brazil. In particular, feasibility studies for a mission to a triple asteroid will be included. Triple asteroid missions have significant importance for advancing our understanding of the early solar system and the formation of planetary bodies. These missions provide unique opportunities to study the complex interactions within multi-body systems, offering insights into the gravitational dynamics, compositional diversity, and evolutionary processes of asteroids. Understanding triple asteroids can also enhance our knowledge of resource availability for future space exploration and potential planetary defense strategies. By investigating their orbits, physical properties, and surface characteristics, scientists can gather critical data that may inform future asteroid mining endeavors and help mitigate the risks posed by near-Earth objects. In particular, a mission to the asteroid 2021 SN263 have been studied at INPE and other institutions. The results will be presented, including possible orbits, launch dates, velocity impulse costs and other important parameters for the mission.
