Abstract

It has been recently found that Europa, the second satellite of Jupiter, has warm water under its icy surface. Biological explorations are needed so as to investigate the existence of life on Europa and to clarify the origin of life on the Earth. A preliminary analysis is carried out on flight trajectories from the Earth to Jupiter and on the feasibility of aerobraking in Jovian atmosphere for deploying a satellite around Europa. Several interplanetary orbits from the Earth to Jupiter are calculated and that having the smallest Jovian insertion energy is selected. It is clearly shown that aerobraking is by far more advantageous for reduction of satellite weight than retrofiring of rocket motors.
