With it we were able to discover rings around the Centaur Chariklo and the TNO Haumea detect sub-km TNOs and drastic variations of Pluto's atmospheric pressure. The knowledge of such characteristics has been important in understanding the origin and evolution of the solar system. Since the technique translates photometric resolution into astrometric resolution a better photometric condition will provide improved constraints in the determination of the body’s physical characteristics. As a natural step forward observing stellar occultation by spacecraft will provide better photometric circumstances avoiding the noise caused by atmospheric fluctuations. With CHEOPS five interesting stellar occultations have considerable chances of being observed involving the Neptunian satellite Triton where we can further study its atmosphere the TNO Quaoar and Centaur Chiron where we can improve the knowledge about the presence of rings and the TNO 2002MS4 where we can explore its environment. Note: We do not use the CHEOPS Exposure Time Calculator for this science case because we need the highest time resolution possible in imagette mode. [truncated! Please see actual data for full text]
