Explorers of the Outer Planets: The Journey of the Pioneers and Voyagers from Earth to Neptune and Beyond

In the book «Explorers of the Outer Planets: The Journey of the «Pioneers» and «Voyagers» from Earth to Neptune and Beyond», Igor Lisov narrates in captivating detail the history of the preparation, planning, funding, launches, and flights of the «Pioneers» and «Voyagers» — spacecraft tasked with investigating the planets of the outer Solar System. These expeditions provided incredibly valuable information about Jupiter, Saturn, Uranus, and Neptune — celestial bodies that humanity's knowledge of was previously quite superficial. Two «Voyagers» are still in flight today: gradually losing power, they stop sending signals and move further away from Earth, beyond the Solar System. These ships will never return, yet aboard the «Voyagers» are messages from Earthlings intended for extraterrestrial civilizations — in case such a meeting ever occurs.
