Abstract

To examine the feasibility of Japan's own Jovian-system exploration, the effectiveness of aeroassist is analyzed by trajectory calculation of flights through Jovian atmosphere. As a result, aeroassist enables hyperbolically-approaching spacecraft to be inserted into Jovian circumference orbits. And moreover, it is clarified that aeroassist is by far more effective than rocket retrofiring as far as weight is concerned. Consequently, Japan's own Jovian exploration will be feasible if carried out by aeroassist.
