Through space exploration, we gain a new perspective to study Earth and the solar system. The number of missions based on the study of the surface and interior of the planets are increasing every year, and the aerobraking phenomena are inevitable when we are very close to a planet atmosphere. On the other hand, several missions to other planets have already exploited aerobraking, in order to...
