Nowadays, using modern technologies, five volunteers are sent on a spacecraft to the Saturn system. This may sound incredible, but the author of “World Oceans” explores such a scenario in detail, taking into account the technological capabilities available today. What trials await the participants of a seven-year journey? What new horizons will this mission open? These questions are revealed in the book. Saturn’s selection is also not random: its moons—with extensive underground oceans—are the closest candidates for discovering extraterrestrial life.
